主要介绍特高压断路器容性电流开合试验方法——合成试验法和直接试验法。
This paper mainly introduces test methods of synthetic test and direct test for capacitive current switching for ultra-high-voltage(UHV) circuit breakers.
KA5为跳闸报警继电器。当设备产生偏励磁、可控硅故障、过电流等故障时，KA5吸合，断路器分励线圈得电跳闸，切断主电源。
When there are bias excitation, controllable silicon failure, over current and other failures, KA5 gets absorbed and breaker loop trips by powered on so as for switching off main power supply.
通过对当前级位进行采样，控制级位的升、降和主断路器的分、合，完成机车自动过分相过程。
The system samples the current grade value and controls the grade and the main circuit breaker to avoid shorting the different phase power or damaging...
要求断路器在技术条件规定的各种自然环境、各种线路条件下都能可靠地开合电路；
