①當電氣設(shè)備發(fā)生漏電時，出現(xiàn)兩種異?，F(xiàn)象：

　　一是，三相電流的平衡遭到破壞，出現(xiàn)零序電流；

　　二是，正常時不帶電的金屬外殼出現(xiàn)對地電壓（正常時，金屬外殼與大地均為零電位）。

　?、诹阈螂娏骰ジ衅鞯淖饔寐╇姳Ｗo器通過電流互感器檢測取得異常訊號，經(jīng)過中間機構(gòu)轉(zhuǎn)換傳遞，使執(zhí)行機構(gòu)動作，通過開關(guān)裝置斷開電源。電流互感器的結(jié)構(gòu)與變壓器類似，是由兩個互相絕緣繞在同一鐵心上的線圈組成。當一次線圈有剩余電流時，二次線圈就會感應(yīng)出電流。

　　③漏電保護器工作原理將漏電保護器安裝在線路中，一次線圈與電網(wǎng)的線路相連接，二次線圈與漏電保護器中的脫扣器連接。當用電設(shè)備正常運行時，線路中電流呈平衡狀態(tài)，互感器中電流矢量之和為零（電流是有方向的矢量，如按流出的方向為“＋”，返回方向為“－”，在互感器中往返的電流大小相等，方向相反，正負相互抵銷）。由于一次線圈中沒有剩余電流，所以不會感應(yīng)二次線圈，漏電保護器的開關(guān)裝置處于閉合狀態(tài)運行。當設(shè)備外殼發(fā)生漏電并有人觸及時，則在故障點產(chǎn)生分流，此漏電電流經(jīng)人體？大地？工作接地，返回變壓器中性點（并未經(jīng)電流互感器），致使互感器申流入、流出的電流出現(xiàn)了不平衡（電流矢量之和不為零），一次線圈申產(chǎn)生剩余電流。因此，便會感應(yīng)二次線圈，當這個電流值達到該漏電保護器限定的動作電流值時，自動開關(guān)脫扣，切斷電源。
