描述

“漏電保護(hù)器”主要動作性能參數(shù)有：額定漏電動作電流、額定漏電動作時(shí)間、額定漏電不動作電流。其他參數(shù)還有：電源頻率、額定電壓、額定電流等。

①額定漏電動作電流：

在規(guī)定的條件下，使漏電保護(hù)器動作的電流值。例如30mA的保護(hù)器，當(dāng)通入電流值達(dá)到30mA時(shí)，保護(hù)器即動作斷開電源。

②額定漏電動作時(shí)間：

是指從突然施加額定漏電動作電流起，到保護(hù)電路被切斷為止的時(shí)間。例如30mA×0.1s的保護(hù)器，從電流值達(dá)到30mA起，到主觸頭分離止的時(shí)間不超過0.1s。

③額定漏電不動作電流：

在規(guī)定的條件下，漏電保護(hù)器不動作的電流值，一般應(yīng)選漏電動作電流值的二分之一。例如漏電動作電流30mA的漏電保護(hù)器，在電流值達(dá)到15mA以下時(shí)，保護(hù)器不應(yīng)動作，否則因靈敏度太高容易誤動作，影響用電設(shè)備的正常運(yùn)行。

④其他參數(shù)如：

電源頻率、額定電壓、額定電流等，在選用漏電保護(hù)器時(shí)，應(yīng)與所使用的線路和用電設(shè)備相適應(yīng)。漏電保護(hù)器的工作電壓要適應(yīng)電網(wǎng)正常波動范圍額定電壓，若波動太大，會影響保護(hù)器正常工作，尤其是電子產(chǎn)品，電源電壓低于保護(hù)器額定工作電壓時(shí)會拒動作。漏電保護(hù)器的額定工作電流，也要和回路中的實(shí)際電流一致，若實(shí)際工作電流大于保護(hù)器的額定電流時(shí)，造成過載和使保護(hù)器誤動作。
