    摘 要:配電網的開關設備大多數故障是由其操作機構故障引起的,通過在一體化集成的智能柱上開關上加裝傳感器,監測獲取操作機構的分、合閘線圈和儲能電機工作電流,結合環境溫濕度等特征信息的變化,提出了一種針對操作機構的多元信息狀態監測和故障診斷方法,通過對比同一操作機構的多次電流波紋變化,結合環境溫濕度的變化,預測操作機構的性能變化趨勢,綜合診斷操作機構的性能狀態,提前發現潛在的設備故障隱患,給出相對應的檢修意見,有助於全麵了解開關設備的各項狀態指標,降低開關設備的故障率。

    Abstract: Most of the faults of switchgear in distribution network are caused by the faults of its operating mechanism. Via adding sensors on the integrated column switch to monitor the working current of making and breaking coil and energy-stored motor and combining with the changes of the environmental temperature and humidity etc feature information, this paper proposed a kind of multi-information state monitoring and fault diagnosis method for the operating mechanism. By comparing the multiple current ripple changes of the same operating mechanism and combining with changes in environmental temperature and humidity, this paper forecasted the trend of performance change of the operating mechanism, diagnosed the performance status of the operating mechanism comprehensively, so that the potential equipment failure hidden danger was found out in advance and the corresponding maintenance suggestions were given, which is helpful to understand the state indicators of the switchgear comprehensively, reducing the failure rate of the switchgear.
    Key words: distribution switch; operation mechanism; condition monitoring; fault diagnosis
