摘 要：某變電站252 kV SF6瓷柱式斷路器防跳回路因設計缺陷使斷路器跳位監視回路存在寄生回路，導致操作箱對斷路器的跳位監視發生錯誤。分析了防跳回路對跳位監視回路的影響，并對比了550 kV H-GIS斷路器出現的類似問題。闡述了成因和解決方法，對防跳回路的設計提出了改進，在跳位監視回路中串聯斷路器常閉輔助節點和就地防跳繼電器的常閉節點，以解決寄生回路對跳位監視的影響。

Abstract: The anti-pumping circuit of a 252 kV SF6 circuit breaker used in a certain substation existed parasitic circuits in its open-position circuit because of design deficiency, which caused the operation box to make mistakes towards the open-position monitoring of the circuit breaker. This paper analyzed the effect of the anti-pumping circuit on the open-position monitoring circuit, and compared with a similar phenomenon that happened to the 550 kV H-GIS circuit breaker. The factor and solution has been explained, and it has also proposed improvement towards the design of the anti-pumping circuit. In the open-position monitoring circuit, the normally closed auxiliary nodal point of the circuit breaker was connected in series to the normally closed nodal point in in-site anti-pumping relay of the circuit breaker to remove the effect of parasitic circuits on open-position monitoring.
Key words: open-position monitoring; anti-pumping circuit; circuit breaker
