漏電保護器的種類有哪些

發布日期:2022-10-09 點擊率:118


漏電保護器按不同方式分類來滿足使用的選型。如按動作方式可分為電壓動作型和電流動作型;按動作機構分,有開關式和繼電器式;按極數和線數分,有單極二線、二極、二極三線等等。下面按動作靈敏度和按動作時間分類:①按動作靈敏度可分為:高靈敏度:漏電動作電流在30mA以下;中靈敏度:30~1000mA;低靈敏度:1000mA以上。②按動作時間可分為:快速型:漏電動作時間小于0.ls;延時型:動作時間大于0.1s,在0.1-2s之間;反時限型:隨漏電電流的增加,漏電動作時間減小。當額定漏電動作電流時,動作時間為0.2~1s;1.4倍動作電流時為0.1,0.5s;4.4倍動作電流時為小于0.05s。
