摘要
由于220 kV GIS断路器跳闸回路中手动跳闸回路与保护跳闸回路未分离,导致发生事故时断路器可能无法成功跳闸从而使事故扩大化,危及人身及财产的安全。对此危急缺陷进行分析,探讨缺陷的修改方案及其可行性,并从中选出安全、经济、可行的修改方案进行对比剖析。
Due to 220 kV GIS circuit breaker trip circuit of the manual trip circuit and protection trip circuit aren＇t separate, the circuit breaker may not be able to disconnect when the accident happened ,and the accident will become more serious ,it may do harm to personal and property safety. Defects are analyzed ,and defects modification methods and the feasibility of modified methods were explored, and feasible modification methods were selected for comparative analysis.
