变电站防控二次雷击及地电位技术研究

Research on technology of preventing and controlling secondary lightning strike and ground potential in substations

雷电防护技术在电力系统中十分重要,供电系统的稳定运行对于社会的正常运转至关重要,但二次雷击和地电位反击等问题仍然存在,给供电系统带来了不稳定性和风险。为解决这些问题,对变电站防控二次雷击及地电位技术进行了研究,以提高焦煤集团供电系统的稳定性和可靠性。引入ALPS消散阵系统,通过实验和数据分析,验证了以消散阵系统ALPS Model D和ALPS Model T-C球形电离(极化)器为核心的解决方案的有效性,可以显著降低二次雷击和地电位反击对供电系统的影响,提高系统的安全性和可靠性。

The importance of lightning preventing and controlling technology in the power system is self-evident.The stable operation of the power supply system is crucial to the normal operation of society.However,problems such as secondary lightning strikes and ground potential counterattacks still exist,bringing instability and risks to the power supply system.In order to solve these problems,the aim is to conduct research on substation prevention and control of secondary lightning strikes and ground potential technology to improve the stability and reliability of the Jiaozuo Coal Industry Group power supply system.The ALPS dissipative array system was introduced,and through experiments and data analysis,the effectiveness of the solution with the dissipative array system ALPS Model D and ALPS Model T-C spherical ionizer(polarizer)as the core was verified,which can significantly reduce the impact of secondary lightning strikes and ground potential counterattacks on the power supply system,and improve the safety and reliability of the system.
