During prolonged hot weather, how to cool transformers to ensure their proper operation
Thread Content
To prevent the transformer’s temperature from rising further, ensure the reliable operation of the equipment, and guarantee power supply for residents, the team members carried one heavy ice block after another, each weighing 50 pounds, placed them carefully inside the transformer room, closed the door, and then rushed to the next location. Sometimes, the ice blocks are too large, so they have to use hammers to break them into smaller pieces before they can place them in the safe area below the transformer. After several consecutive intervals, every team member was sweating profusely. “Cooling the transformer is one of our regular tasks these days; we’re all used to it. ”Team member Fan Liehu appears young, but prolonged exposure to the scorching sun has darkened his skin, making him look even more steady and reliable. In fact, that is indeed the case with him; he is meticulous and hardworking in his job. He said, “As long as the high temperatures persist, we will not retreat.” ” Under the scorching sun, Fan Liehu and his teammates, dressed in blue work uniforms and red jackets, saw their clothes go from wet to dry again and again as waves of heat hit them. After nearly two hours of fighting, cooling work was completed on transformers at 8 locations, including Fengwo Street, Nongxiao Street, Zhongxing Road, Xinghan Road, and the Telecommunications Community.
On July 21, staff from State Grid Wuyi County Power Supply Company activated the sprinkler system to cool the main transformers at two substations whose total capacity is 2*50 megavolts-amps and which are responsible for supplying power to the main urban area of Wuyi. Provided by IC: The electricity supplied to residents must be converted from its high voltage to a low voltage using a transformer. The transformer is the “heart” of a substation. The transformer spray cooling system is designed primarily to cool the main transformer; it achieves this by using water pipes and misting nozzles to release water mist, similar to the artificial rainfall we are familiar with. The system will start operating automatically, using water pipes and nozzles to spray water on the transformer; within two or three minutes, this will help cool it down, giving it a \"cooling effect\" and reducing its overall temperature by about 10 degrees. Another period of continuous high temperatures has arrived; it’s not only people who are affected by the heat, but also various mechanical devices. Since July, the persistent high temperatures – reaching 39 and 40 degrees – have placed severe safety challenges on the transformers that operate around the clock. To ensure the safe operation of transformers, State Grid Wuyi County Power Supply Company, in light of the increasing load on the power grid, promptly removed dust and dirt from the gaps in the transformers and installed spray cooling systems to improve heat dissipation, achieving an effective temperature reduction of 10 degrees. This ensures the safe and stable operation of electrical equipment, as well as the stability and safety of electricity supply for residents.
It was the hottest part of the day; after being exposed to the sun all morning, the temperature in the converter station kept rising, with waves of heat emanating from the coolers of the converter transformers. The maintenance staff confirmed that all 4 coolers had started up and made a record on the work sheet. Subsequently, 4 maintenance workers carried 2 pieces of ice weighing 5 kilograms each, ready to cool down the converter transformer.
Fog guns used to “shower” transformers. Recently, the Meteorological Observatory of Fengdu County in Chongqing issued a \"red alert for high temperatures,\" with the maximum daily temperatures in various areas of the county rising to 40 degrees Celsius. Affected by the persistent high temperatures, citizens make frequent use of air conditioners, electric fans and other cooling appliances, which keeps the power supply load rising and causes the power supply equipment to operate under heavy load, putting pressure on the operation of the power grid. On August 9, inside the 110-kilovolt Sanhe Substation in Fengdu County, Chongqing, the intense heat was almost suffocating. At the scene, the reporter saw power grid workers wearing work uniforms and safety helmets working to cool down the transformers; they used misting machines to spray water on the transformers in order to reduce their temperature and ensure their safe and reliable operation.
