1、根據(jù)不同的電氣設(shè)備的供電方式選用不同的漏電保護(hù)器

　　單相220V電源供電的電氣設(shè)備，應(yīng)選用二極二線或單極二線式漏電保護(hù)器。

　　三相三線式380V電源供電的電氣設(shè)備，應(yīng)選用三極式漏電保護(hù)器。

　　三相四線式380V電源供電的電氣設(shè)備或單相設(shè)備與三相設(shè)備共用的電路，應(yīng)選用三極四線或四極四線式漏電保護(hù)器。

　　2、根據(jù)電氣線路的正常泄漏電流，選擇漏電保護(hù)器的額定漏電動(dòng)作電流

　　選擇漏電保護(hù)器的額定漏電動(dòng)作電流值時(shí)，應(yīng)充分考慮到被保護(hù)線路和設(shè)備可能發(fā)生的正常漏電流值。

　　選用的漏電保護(hù)器的額定漏電不動(dòng)作電流，應(yīng)小于電氣線路和設(shè)備的正常漏電電流的大值的2倍。

　　漏電保護(hù)器的額定電壓、額定電流、短路分?jǐn)嗄芰?、額定漏電電流、分?jǐn)鄷r(shí)間應(yīng)滿足被保護(hù)供電線路和電氣設(shè)備的要求。

　　漏電保護(hù)器接線錯(cuò)誤方式：

　　1、用于支線保護(hù)時(shí)，各支線應(yīng)有各自的專用零線，且兩相鄰支線路的零線不得相連。如果將兩分支線路相連，零線中的電流互流，破壞零序電流互感器內(nèi)的工作電流平衡，使漏電保護(hù)器發(fā)生誤動(dòng)作。如果想就近利用動(dòng)力分支線的零線作為照明分支線的零線，則會(huì)造成動(dòng)力分支線的漏電保護(hù)器動(dòng)作。

　　2、一個(gè)用電設(shè)備只能接在一條保護(hù)支路內(nèi)，不得跨接在兩條分支回路內(nèi)，不得接在零序互感器的前面，也不得采取一線一地制供電，否則，會(huì)導(dǎo)致漏電保護(hù)器誤動(dòng)作。

　　3、裝有漏電保護(hù)器和未裝漏電保護(hù)器的用電設(shè)備，不得共用一個(gè)接地裝置。例如，當(dāng)電機(jī)M1的絕緣損壞而外殼帶電時(shí)，電機(jī)M2的外殼也帶電，由于電流沒有經(jīng)過漏電保護(hù)器，所以未起到漏電保護(hù)的作用。

大功率功放的變壓器必須做的非常大，這樣就會(huì)導(dǎo)致：笨重，發(fā)熱量大。

　　4、單相負(fù)荷應(yīng)盡可能均衡分配。如果分配不均（如一相的線路偏長，設(shè)備集中），則負(fù)荷較重的一相，其漏電電流偏大，因而干線的三相不平衡漏電電流增大，達(dá)到一定值時(shí)就會(huì)使干線首端的漏電保護(hù)器動(dòng)作。

所以變壓器的效率很低，一般不會(huì)超過35%。
