The rising temperatures in Antarctica and the Arctic have aroused widespread concern. Recently, shocking images of multiple walruses falling off cliffs and dying on Russia's far north coast have been circulated on the Internet. The ecosystem is a complex system, and every link in it is very important. If a species is destroyed, there will be an irreversible butterfly effect... In the end, it is likely that humans will reap the consequences. Today, let’s talk about birds. It’s spring, everything is growing, and it’s also the season when birds are active. Chirp, chirp! These elves are like jumping notes in nature, adding endless fun to our lives. photography: Wang Zhen’s love for birds is conducive to maintaining ecological balance. to this end, * * A special "Bird Love Week" was also set up. In 1992, the "Implementation Regulations of the People's Republic of China on Terrestrial Wildlife Protection" approved by the State Council established "Bird Love Week" in the form of regulations, and determined a certain week from the end of April to early May each year as "Bird Love Week". We love and protect birds, so the power supply employees are worried about this. Although birds are cute, sometimes they are not so "cute" when it comes to power grid security. One of the important tasks of power grid employees during spring inspections and daily inspections of power lines is to eliminate bird damage. The power grid is very afraid of birds... Whether at home or abroad, a casual search on the Internet will reveal many cases of birds causing power outages. Swipe to see? Electricity leakage, power outage, railway paralysis... they all look scary. The "power" of birds is really not small! How did these terrible results occur? Judging from past cases, there are two main ways in which birds harm the power grid.: 1 The bird is directly electrocuted: If a big bird accidentally touches the wire while flying or playing, it may short-circuit the wire and cause a power outage. Of course, a bird standing on a wire will not get electrocuted. But if two birds standing on different wires come into contact, a circuit will be formed and they will get electrocuted. On the evening of March 2, 400 villagers in Sanfang Village, Shipai Town, Datian County, Sanming, Fujian Province suffered a power outage in their homes. Daejeon Power Supply Company employees inspected in the rain and found that the fault was caused by a pheasant touching the wire. (Liao Yingxian) 2 Indirect damage to lines and equipment: The bird's nest is built on a power pole. The branches and wires used to build the nest may cause short circuits and power outages. ； If bird excrement falls on the insulator, it will greatly reduce the performance of the insulator. On April 10, members of the party member service team of the maintenance and construction area of the Gucheng County Power Supply Company in Xiangyang, Hubei Province discovered that there was a major safety hazard of serious arcing on the No. 82 tower bow sub-line of the 35 kV Liuda Line. After investigation, it was found to be caused by a bird's nest. Power supply employees quickly took power outage measures to eliminate hidden dangers in line equipment. (Zhang Bo) Therefore, we must guard against birds! Have you ever seen a little thing flicker on a wire? That is one of the most commonly used bird repellents. It's a bit like a small windmill that spins in the wind. Each "blade" is equipped with a small mirror, which will reflect light while turning under the sunlight. It uses rotation and reflection to scare away birds and prevent them from building nests on electric poles. Power milfoil based on bird life * We take measures such as patrolling, demolition, prevention, and diversion to eliminate bird damage from the two aspects of "human defense + technical prevention" and maintain the stable operation of transmission and distribution lines. 1 defense: Power supply employees installed bird repellents and anti-bird stingers on lines and equipment, and strengthened daily line inspections to prevent birds from building nests on lines and equipment. Bird repelling equipment is really a bit diverse... Strengthen line inspections, especially during the critical period of bird migration and nesting. On April 12, Liu Wen and Chai Hengyuan, employees of Xinjiang Urumqi Power Supply Company, inspected the 220 kV Chaiji traction line I and II in the Chaiwopu area to protect the migration routes of migratory birds. (Wang Jinkui) On March 25, employees Zhou Sulinlong and Huang Hongsheng of Hefei Feixi Power Supply Company in Anhui Province conducted a special bird prevention patrol on poles 39 and 40 of the 35 kV small-coke line. (Cheng Qing) It is relatively common to install bird repellents. On March 12, employees at the Liji Power Supply Station of Huangpi Power Supply Company in Wuhan, Hubei Province installed bird repellents on the Xiajiatian branch line of the 10 kV Songji Line. (Wang Zhicheng and Chen Tao) On March 16, Liu Chenglong, an employee of Shandong Linyi Tancheng Power Supply Company, installed a bird repellent on pole 32 of the 10 kV Xinwen branch line. (Xu Hui) On March 18, Liang Xinxin, an employee of Tangzhuang Power Supply Station of Weihui Power Supply Company in Xinxiang, Henan Province, installed a bird repellent device on the 10 kV Heqin Line in Tangzhuang Town. (Zhang Haiqiang and Qin Mingliang) On April 7, Chen Quanyu, an employee of the Distribution Operation and Inspection Center of Tongshan District Power Supply Company in Xuzhou, Jiangsu Province, installed a bird repellent on pole 39 of the 10 kV South Water Line. (Li Mingjun) On March 3, Zhang Zhong, an employee of the Jiaocheng County Power Supply Company in Luliang, Shanxi Province, installed a bird repellent on pole 39 of the Xiling Branch of the Guangxing Line. (Zhang Laizhong) On March 4, Shaanxi Ankang Power Supply Company employee Li Kang and others installed a bird repellent on the 10 kV Park III line of Wuli Park Station. (Zhu Qianqian and Ma Zhijun) On March 4, Zang Chuanliang and Yang Zongai, employees of Zhucheng Power Supply Company in Weifang, Shandong Province, installed a bird repellent on pole 12 of the 10 kV Haogezhuang South Line. (Gu Xueqing) Bird-proof stingers are generally installed on higher-voltage towers to repel large birds. On April 1, operation and maintenance employees of Hubei Power Transmission and Transformation Company installed anti-bird spurs at key locations on the towers of Jingzhou 500 kV Yuxing Line I and Line II. (Li Yong) On March 23, Wei Zhong and Wang Zhen, employees of Hubei Suizhou Power Supply Company, installed anti-bird spikes on Tower 4 of the 110 kV Xuyang Line. (Yang Lei and Zhang Wan) Let some natural enemy units such as "snakes" and "eagles" try to innovate, and the effect seems to be pretty good. The Hutuo Power Supply Station of Leting County Power Supply Company in Tangshan City, northern Hebei Province, took advantage of the natural law that birds are afraid of snakes and installed plastic simulated snakes on the poles of Gaojia's 10 kV wiring. It has been verified that the effect of repelling birds is obvious. (He Hongyun) Employees of Liaoning Yingkou Power Supply Company developed a new type of intelligent bird repellent device: The appearance is designed in the shape of an eagle according to 1:1, and there are infrared induction monitoring system, sound system and charging system inside. When the infrared sensing system detects that birds enter the 1.5-meter radius of the device, it will trigger the sound system and emit ultrasonic waves to drive away the birds. The unit is self-powered using solar panels. (Xie Zhifeng) There are also special sonic bird repellers. On April 12, Cui Maohong, an employee of the Xinfu District Power Supply Company in Xinzhou, Shanxi Province, installed an ultrasonic bird repeller on pole 30 of the 10 kV Donglou Line trunk line in Donglou Township. (Peng Jianyou) On March 28, employees of Hebei Baoding Power Supply Company installed ultrasonic bird repellers on the tower of the 500 kV Dafang II Line. (Yang Yang) Some have made some improvements to the cross arm to make it more difficult for birds to build nests. Employees of Jiyang Power Supply Company in Jinan, Shandong Province innovatively invented the anti-bird cross arm. They added a triangular angle iron to the tower hoop and the end of the insulator to make it more difficult for birds to build nests. This kind of cross arm is widely used and has obvious anti-bird effect. (Chen Bin) If you really can’t defend yourself, protect yourself! Use anti-bird baffles to protect key parts of the tower. On December 22, 2019, Wan Haifeng and Zhong Yongchun, employees of Jiangxi Electric Power Maintenance Company, replaced the anti-bird baffle on Tower 45 of the 500 kV Ma Shi II Line. (Zou Song and Gong Yude) On June 24, 2019, Lian Xin and Wang Fengbo, employees of the live shift in the transmission and inspection room of Anhui Fuyang Power Supply Company, installed anti-bird baffles on the structure of the 220 kV Garden Substation. (Ren Changbo) Birds cannot be driven away at once. More considerations must be made for their reproduction. The power supply employees are also worried about this. 2 move: For those that have built nests on power facilities, power supply employees help them move their nests ； For those that have not built nests yet, power supply employees "build houses" for them in a safe place in advance. On March 26, Hubei Xianning Power Supply Company Maintenance Branch carried out transmission inspection * When members of the service team were patrolling the 220 kV Sunbao Line, they discovered five baby birds in a bird's nest on the line. After discussion, the power man carefully "moved" the bird to a new home, which not only ensured the safety of the power grid, but also protected the young life. (He Chengjiang Bolongqun) On March 20, employees of Zhejiang Ningbo Power Supply Company moved away from the Bird's Nest on Tower 48 along the 220 kV River in Luotuo Town, Zhenhai District, Ningbo. (Wang Mubin and Zhao Qin) On March 20, employees Lu Shaolong and Zhou Ze of Shuyang Power Supply Company in Suqian, Jiangsu Province removed a bird's nest with electricity on pole 54-12 of the 10 kV Nangong Line. (Zhong Yingying) On April 1, Wu Yuze, a transmission and inspection employee of Xiaoshan District Power Supply Company in Hangzhou, Zhejiang, and his colleagues "moved" birds on Tower 3 of the 110 kV Wenyan Line. (Cai Minyan and Li Jun) Protect birds, save birds, power grid squirrels love the birds that build nests on iron towers. Although they often cause bad consequences, they really don’t mean it! After all, birds are our humans’ best friends. Look, aren't they cute~ But these big birds always fall in love with tall and strong iron towers... Faced with these innocent little cuties, Power Supply is very caring and patient. They do so many things in their daily work: 1 Guardian bird babies grow up in Heilongjiang In June 2014, Wang Qike, a transmission operation and maintenance employee of Heilongjiang Daqing Power Supply Company, discovered an extra-large bird's nest on the top of No. 18 Tower of the 220 kV Dachun Line A and B. It turns out that this is no ordinary bird; * * There are only about 3,000 Oriental white storks in the world, a protected bird. After professional discussion, it was finally decided to move the Oriental White Storks and sent them to the Longfeng Wetland Reserve Management Center in Daqing City. When they grew up, power supply employees and management center personnel released them together. (Zhang Xinmin) Hebei In 2018, more than 30 Oriental white storks nested and reproduced on the tower of the Xuelianwan-Bijiaquan 35 kV tie line in Fengnan District, Tangshan, Hebei. Fortunately, this was a backup line and was not running with electricity. Su Chunling, a line operation and maintenance employee of the Fengnan District Power Supply Company, and his colleagues guarded them, stepped up inspections, and made every effort to ensure the normal operation of the main power supply and try to avoid using lines where Oriental white storks nest. From April to September, these oriental white storks gave birth to a total of 16 new lives. The protection and efforts of the power supply employees have been best rewarded. (Zhou Yuxiang) In July 2019, Chen Feng, an employee of Fengcun Power Supply Station of Boye County Power Supply Company in Baoding, Hebei Province, guarded the homeless baby birds found while cleaning bird nests on the lines. (Liu Jing) 2 Build a safe haven for them in advance Zhejiang Photography: Not all nests cannot be built on the Wang Mubin Iron Tower. It is actually possible to build nests in corners and corners where there are no lines or equipment underneath. Therefore, Power Supply made this kind of strong iron nest for the birds and installed it in a safe place on the iron tower to guide the birds to come here to build their nests. Li Wengang, director of Daquan Power Supply Station in Jiawang District of Jiangsu Xuzhou Power Supply Company, and his colleagues worked hard to build a perfect bird's nest. They improved on the steel bird's nest and made bird's nests of various shapes such as wooden piles and ovals to attract more magpies to stay. Seeing that the results were limited, they continued to improve the bird's nest. They bought simulated wood, tree branches, green leaves, straw nests and other materials from the Internet, and placed hay inside, successfully creating a third-generation tree branch-style artificial bird nest that looked just like the real thing. After installing the new bird's nest, within a week, their loving bird's nest welcomed a "guest". In the past two years, they have installed nearly 50 "love birdhouses" in the Dali Village area of Jiawang, within Daquan, and near Dadong Mountain. According to statistics, the current bird occupancy rate is 87.5%, reaching the expected goal. The Bird's Nest is installed under the power facilities on the poles and does not affect the normal operation of the lines. “Green waters and green mountains, escorted by ecological bird's nests. We will also make further improvements to increase bird occupancy rates. ”Li Wengang said that the artificial love bird's nest, as the "unique skill" of Daquan Power Supply Station, will be promoted to Jiawang Scenic Area and mountainous areas this year. (Yang Jie and Li Kun) Qinghai Since 2016, State Grid Qinghai Electric Power has launched the "Bird's Nest of Life" public welfare project. * * In nature reserves where many birds live and inhabit, scaffolding and artificial birdhouses on the same tower as power grid lines are erected along the power lines to guide birds to settle down. This work has achieved good results and provided Yushu samples for the protection of the ecosystem in the Sanjiangyuan region. Up to now, there are 3,200 "Birds of Life" in Sanjiangyuan, distributed in 1 city and 5 counties in Yushu Prefecture. According to statistics from power supply employees, 807 bird nests showed signs of nesting, 460 bird nests contained birds, and 310 new baby birds were born. (Xu Xiaotao and Li Juan) 3 During work, power supply employees also saved many birds Hubei - Gray Heron On April 3, 2019, Wan Yingchun, Hu Xiaobin, and Yu Huarui, employees of the Yangxin County Power Supply Company in Huangshi, Hubei Province, heard an unusual bird call on their way to the Zhujiazui Taiwan area for maintenance in the Wanghu Wetland, and followed the sound into the forest. I saw a water bird hanging on the tree struggling hard, making a cooing whine, and blood flowing from the corner of its mouth. Next to it was a nest of still-warm eggs. Hu Xiaobin found a similar type of water bird hanging on another tree, but unfortunately it had died with a fishhook in its mouth. Wan Yingchun quickly and carefully cut off the fishing line and took out the fishhook, freed the injured bird from the tree, and gently wiped the bird's bloody wound with a paper towel. Hu Xiaobin took out his mobile phone to take a photo and found out online that it was a gray heron. After the three of them treated the wounds, they immediately released the gray heron. They saw the gray heron flapping its wings and hovering above the three people's heads for a while before flying away. (Wu Xiaoxi and Liu Wenming) Sichuan - Black Bird On March 25, employees of the Zhonghe Power Supply Station of Huaying Power Supply Branch of Sichuan Guang'an Power Supply Company discovered a black bird accidentally entangled in the protective net while inspecting the 10 kV Zhongjin Line. Electricity workers rescued the bird and released it back into the wild. (Xu Wenyan and Liu Xiangyang) Tianjin - Falcon On the morning of March 29, Liu Mingyang, project manager of Tianjin Power Transmission and Transformation Company, was on his way to Zhangbei— * * On the way to the construction site of the 3R/L002 towers of the UHV project, he suddenly found a "grey stone block" in the middle of the road, and he slowly slowed down the vehicle. “Be careful, the rocks are moving! ”Yu Yanqiu, who was sitting in the passenger seat, said. The two immediately stopped the car to check the situation. “Hey, this is an eagle. It seems to be injured. ” The two carefully put the eagle into the carton. After inspection, they found that its wings were seriously injured and could not fly, so they took it back to the project department. Power transmission and transformation company * Yu Yanqiu and Zhang Zhongqiang, members of the Animal Service Team, applied medicine to stop the bleeding and bandaged the eagle under the remote guidance of the medical staff of the pet hospital. Early the next morning, Liu Mingyang sent it to the local forest police department. “This eagle is called a Falcon. * * Second-level protected animals, thank you for your contribution to wildlife protection during power construction. ”The forest police officer expressed his gratitude, “We will have dedicated personnel to treat the injured wild animal, and we will leave the follow-up work to us. I believe it will be able to fly again in the blue sky soon! ”(Hu Hao and Wang Jiaao) There are many more stories like this... Although birds sometimes affect the safety of power supply, frontline power supply workers still try their best to protect them and let them live in harmony with power supply facilities. Every life is worthy of awe, even if it is an animal or a plant. Human beings and nature have a dialectical and unified relationship. On the one hand, we must conquer nature and ensure our own continued development. ； On the other hand, we must live in harmony with nature, protect the environment, and protect the ecology. This is actually protecting ourselves. Treat the world with a soft heart, and the world will treat us with tenderness in return. Content source: Power release
