style="text-indent:25px">變壓器高壓(110KV及以上)側(cè)單相接地短路應(yīng)裝設(shè)后備保護(hù),作為變壓器高壓繞組和相鄰元件接地故障主保護(hù)的后備。220KV及以上的大型變壓器,高壓統(tǒng)組均為分級(jí)絕緣,其中性點(diǎn)絕緣水平有兩種類型類絕緣水平很低,例如500KV系統(tǒng)的中性點(diǎn)絕緣水平為38KV的變壓器,中性點(diǎn)必須直接接地運(yùn)行;另一類絕水平較高,例如220KV變壓器的中性點(diǎn)絕緣水平為110KV,其性點(diǎn)可直接接地,也可在系統(tǒng)中不失去接地點(diǎn)的情況下不接地運(yùn)行。當(dāng)系統(tǒng)發(fā)生接地短路時(shí),變壓器中性點(diǎn)就將承受中性點(diǎn)對地電壓。為了限割系統(tǒng)接地故障的短路容量和零序電流水平,也為了接地保護(hù)本身的需要,有必要將220KV變器的部分中性點(diǎn)不接地運(yùn)行。電子變壓器安全試驗(yàn)</p><p
