摘要
在实际运行中经常出现因开关本体三相不一致保护误动作问题造成的开关三相跳闸状况发生。本文介绍了开关本体三相不一致保护的原理,从多方面分析了三相不一致保护误动的典型原因,并针对性地提出了相应的改进措施,实际工作证明,经过优化改进后有效避免了开关三相不一致保护误动造成的开关异常动作,具有一定推广价值。
The paper presents the principle of three-phase inconformity protection of the switch body and analyzes the typical cause of three-phase inconformity malfunction and puts forward improved measures.Practice work has proved that abnormal switch action caused by switch three-phase inconformity protection malfunction has been effectively avoided after optimization improvement which has a certain commerical value.
