What are the requirements of the petroleum and petrochemical industry for power surge protectors SPD? http://yunrun.com.cn/tech/2339.html The petrochemical industry is a key sector in China, playing a vital role in the country’s economic development. It features long production chains and a wide range of activities, including oil and gas exploration, oil and gas field development, drilling operations, oil extraction, oil and gas transportation, crude oil storage and transportation, oil refining, chemical production, and the sale of various petroleum products. These activities are aimed at meeting societal needs for gasoline, kerosene, diesel, lubricants, chemical raw materials, synthetic resins, synthetic rubbers, synthetic fibers, fertilizers, and other products. With the progress of society and the development of high-tech, various information devices, precision instruments, computers, and data network equipment are being used more and more widely in petrochemical enterprises. Lightning protection for these devices will also become a key focus of protection efforts for petrochemical enterprises. On the one hand, the use of these devices in the petrochemical industry has greatly accelerated the process of modernization and promoted the development of this industry ； On the other hand, the electronic devices used in the petrochemical industry have poor overvoltage tolerance and low insulation strength, making them highly susceptible to lightning strikes. As the number of lightning strikes on petrochemical facilities increases year by year, the damage caused is severe. Moreover, the petrochemical industry deals with many flammable, explosive, and volatile substances, so the danger posed by lightning strikes is evident. To avoid disruptions in the operation of electronic equipment caused by lightning strikes, or even permanent damage, it is particularly important to enhance lightning protection in the petrochemical industry. Production characteristics of the petroleum and petrochemical industry:
1. Petrochemical enterprises have very high requirements for continuous power supply.
◆ Petrochemical plants operate on a continuous production basis.
◆ There are extremely high demands regarding the reliability and quality of continuous power supply.
◆ Lightning strikes and voltage fluctuations can cause plant shutdowns, production interruptions, and further accidents, with serious consequences.

2. The operating environment of petrochemical power lines is special, and there is a lack of specialized lightning protection technologies.
◆ The high-voltage and low-voltage transmission, transformation, and consumption systems (internal power grids) within the enterprise’s power connection points are under the enterprise’s own management.
◆ These systems are often located in mountainous areas or along rivers and coasts, where the degree of contamination of insulators is high.
◆ Contamination of insulators leads to a decrease in the flashover voltage, thereby reducing the line’s resistance to lightning strikes.
◆ Pollutants generated by petrochemical production, such as sulfur dioxide, nitrogen oxides, dust, and organic vapors, increase the level of contamination on line insulators.

Demand for SPD surge protectors in the petroleum and petrochemical industry:
Consequently, the main requirements for SPD surge protectors in this industry include:
① A fault indication function, allowing maintenance personnel to easily determine whether a device is functioning properly.
② Remote monitoring of the SPD’s status, so that warning messages can be received in the control room.
③ Screw-based wiring, which, although time-consuming, offers a more convenient and reliable way of connecting components.
④ Smaller size, enabling space savings.
⑤ Hot-swapping capability, allowing replacement of spare parts without interrupting system operation
