摘要
介绍了500 kV就地化保护的总体特征和500 kV断路器保护的3种就地化配置方案,分析了断路器保护就地化配置对二次检修模式的影响,探讨了按串配置断路器保护将会给保护校验、技改扩建、基建验收以及紧急消缺带来的改变以及安全风险,为就地化保护应用后的二次检修作业提供参考建议。
This paper introduces the general characteristics of 500 kV local protection and three kinds of local configuration schemes of 500 kV circuit breaker protection, analyzes the effects of local configuration of circuit breaker protection on the secondary maintenance mode, and probes into the changes and safety risks brought about by series configuration of circuit breaker protection to the protection verification, technical transformation and expansion, capital construction acceptance and emergency elimination of defects. It provides reference and suggestion for the secondary maintenance after the local protection is widely applied in an all-round way.
