摘要

对长沙220 kV芙蓉变无功投切过程中的过电压水平及220 V直流电源系统压敏电阻的伏安特性进行了现场试验

并对D25多功能智能电子设备进行了电磁兼容及高温试验

试验结果表明

芙蓉变断路器误动事故与系统开关及无功投切过电压无关。

Abstract

The field tests to overvoltage level during the process of cutting on/off reactive power and the V-A characteristic of varistor used in the 220 V DC power supply system are carried out in the 220 kV Furong substation.The EMC and high temperature tests are developed to the model D25 multifunctional intelligence electronic equipment.The results indicate that the switch accident has nothing to do with the system switch and the overvoltage.
