| 摘 要： | 分、合闸不同期,将使系统在短时间内处于非全相运行,可能会引起中性点电压位移、过电压、加大重合闸时间,对系统稳定性不利。本文对LW10B-252型断路器进行试验,分析了液压系统油压在闭锁范围内和分合闸时间的关系以及对同期性分合闸的影响。

| Abstract: | Non-simultaneous opening or closing of the three phases of circuit breaker can lead to a short time open-phase operation in power system,and perhaps causes neutral point voltage displacement or overvoltage,prolong the reclosing time delay,and is disadvantage to the stability of power system.This paper analyses the relationship between oil-pressures in the latching range of hydraulic system and closing/opening time,and the effect on the opening or closing simultaneity. |
