摘要
简要介绍了非全相运行对系统的影响及三相不一致保护的重要性,并针对珠海新建500 k V加林变电站在验收断路器本体三相不一致保护时出现的易错易漏点进行分析归纳总结,最后提出节省成本的优化验收流程。
The impact of open-phase operation on system and the impotance of three-phase inconsistent protection are introduced. The error-prones, which occur during 500 k V circuit-breaker three-phase inconsistent protection acceptance, are summarized for 500 k V Zhuhai Jialin transformer substation. The optimization accptance flow is proposed for cost saving.
