1.In a10kV distribution system,when shunt ca-pacitors are switched off by vacuum circuit breakers,restrike overvoltage often occurs.
力系统中使用真空断路器切除无功补偿用联器时,易产生重燃过,严重影响联的安全运行。
2.Moreover, the proposed control system is of some fault diagnosis and protection functions, such as overcurrent, overvoltage-undervoltage, overtemperature and parameter overrun.
同时,该源控制系统还具有过流、过欠、过热、参数超限等故障诊断与保护功能。
3.This paper describes the mechanism that multiple reignition of breaker can restrain or increase progressively the switching-overvoltage during switching off inductive or capacitive load.
论述了开关在开断感负载时多次重燃对过的抑制递升机理。
4.Multiple reignition makes the frequency and amplitude of overvoltage increase and might do harm to transformer coils by cumulative effects for its surge steepness.
