中間繼電器的原理是將一個輸入信 變成多個輸出信 或將信 放大（即增大繼電器觸頭容量）的繼電器。其實質是電壓繼電器，但它的觸頭較多（可多達8對）、觸頭容量可達5-10A、動作靈敏。當其他電器的觸頭對數不夠時，可借助中間繼電器來擴展他們的觸頭對數，也有通過中間繼電器實現觸電通電容量的擴展。 2、聽：A、聽其是否有很響的吱—的聲響，如有則可能是（1）電源電壓低；（2）點上有臟物或動靜鐵芯面上有臟物。若聽到咔咔—器吸不上的聲音，多為兩種情況（1）電源電壓低；（2）順吸力不夠。3、聞：聞一聞有沒有焦味，如有請查一下繞組和觸點。 在電力系統中，、可靠運行的重要屏障，繼電保護裝置能否正確動作，它主要依賴于外部開入的電氣量、開關量和裝置自身邏輯。其中重要的電氣量之一就是電壓。繼電保護裝置通過采樣對其分析與判斷，檢測出電壓斷線，就會發出PT斷線告警信 并閉鎖由距離元件或功率方向元件等組成的保護，如果不及時處理，就會嚴重影響繼電保護裝置的可靠運行。

三相負荷中，任何時候這三種功率總是同時存在：視在功率S=1.732UI有功功率P=1.732UIcosΦ無功功率Q=1.732UIsinΦ功率因數cosΦ=P/SsinΦ=Q/S當三相負載平衡時：P=3*U相*I相*cosφ=√3*U線*I線*cosφ當三相負載不平衡時：分別計算各相功率，再求?。 為此其額動作電流只需躲開正常泄漏電流值即可（毫安級），所以能十分靈敏地切斷接地故障，和防直接。而空氣開關就是純粹的過電流跳閘（安級）。空氣開關分為：微型斷路器和塑殼斷路器兩種，他們的基本功能有：1·過流、過載保護；2·短路保護。
