為什么回路電流走零線不走地線,而漏電流走地線不走零線,零線地線原理是什么?這是由配電系統(tǒng)的接線方式?jīng)Q定的。~為三相五線制接線示意圖。以L1相、單相設(shè)備為例。三相變壓器次級線圈產(chǎn)生的交流電壓,經(jīng)L1相線圈首端(火線)L1線單相設(shè)備零線(N)回到線圈末端,形成回路,滿足了產(chǎn)生電流的必要條件,即有電源和閉合回路,因而產(chǎn)生了工作電流,使設(shè)備正常工作。~為帶漏電保護(hù)空開。再來看看保護(hù)地線(PE)的接法。從圖可見,在變壓器端零線(N)和保護(hù)地線(PE)接法沒有不同,但在設(shè)備端就完全不同了,它只接金屬外殼或其它與火線和零線都絕緣的導(dǎo)電金屬部分,因此正常情況下,保護(hù)地線(PE)與電源之間沒有形成回路,因而也就沒有電流。

一般情況下,在三相四線制線路中,零線截面要大于相線截面的50%。合理選取零線截面是由于這類線路的負(fù)荷構(gòu)成中,單相負(fù)載占有很大比重,而且用電時間上也有差異,各相負(fù)荷處于不平衡狀態(tài),零線上經(jīng)常會有電流流過,如果零線選擇不當(dāng),就容易發(fā)生燒斷零線事故而造成大面積燒壞電氣設(shè)備事故。接至用電設(shè)備的保護(hù)零線應(yīng)有足夠的機(jī)械強(qiáng)度,應(yīng)盡量按IEC標(biāo)準(zhǔn)選擇零線的截面和材質(zhì),架空敷設(shè)的保護(hù)零線應(yīng)選用截面不小于10mm2的銅芯線,穿管敷設(shè)的保護(hù)零線應(yīng)選用截面不小于4mm2的銅芯線。

為什么回路電流走零線不走地線,而漏電流走地線不走零線,零線地線原理是什么?這是由配電系統(tǒng)的接線方式?jīng)Q定的。~為三相五線制接線示意圖。以L1相、單相設(shè)備為例。三相變壓器次級線圈產(chǎn)生的交流電壓,經(jīng)L1相線圈首端(火線)L1線單相設(shè)備零線(N)回到線圈末端,形成回路,滿足了產(chǎn)生電流的必要條件,即有電源和閉合回路,因而產(chǎn)生了工作電流,使設(shè)備正常工作。~為帶漏電保護(hù)空開。再來看看保護(hù)地線(PE)的接法。從圖可見,在變壓器端零線(N)和保護(hù)地線(PE)接法沒有不同,但在設(shè)備端就完全不同了,它只接金屬外殼或其它與火線和零線都絕緣的導(dǎo)電金屬部分,因此正常情況下,保護(hù)地線(PE)與電源之間沒有形成回路,因而也就沒有電流。

一般情況下,在三相四線制線路中,零線截面要大于相線截面的50%。合理選取零線截面是由于這類線路的負(fù)荷構(gòu)成中,單相負(fù)載占有很大比重,而且用電時間上也有差異,各相負(fù)荷處于不平衡狀態(tài),零線上經(jīng)常會有電流流過,如果零線選擇不當(dāng),就容易發(fā)生燒斷零線事故而造成大面積燒壞電氣設(shè)備事故。接至用電設(shè)備的保護(hù)零線應(yīng)有足夠的機(jī)械強(qiáng)度,應(yīng)盡量按IEC標(biāo)準(zhǔn)選擇零線的截面和材質(zhì),架空敷設(shè)的保護(hù)零線應(yīng)選用截面不小于10mm2的銅芯線,穿管敷設(shè)的保護(hù)零線應(yīng)選用截面不小于4mm2的銅芯線。
