一、產品概述

在電(dian)(dian)(dian)力(li)系(xi)(xi)統(tong)中(zhong)(zhong)，單(dan)相(xiang)(xiang)(xiang)接(jie)地(di)(di)故(gu)障(zhang)(zhang)約占全(quan)部故(gu)障(zhang)(zhang)的(de)(de)(de)85%,而且這些單(dan)相(xiang)(xiang)(xiang)接(jie)地(di)(di)故(gu)障(zhang)(zhang)中(zhong)(zhong)，85%以(yi)上(shang)是(shi)瞬時(shi)的(de)(de)(de)和可(ke)以(yi)恢(hui)復的(de)(de)(de)。電(dian)(dian)(dian)力(li)系(xi)(xi)統(tong)運行的(de)(de)(de)安全(quan)性和供電(dian)(dian)(dian)的(de)(de)(de)可(ke)靠(kao)性，在其(qi)它條件相(xiang)(xiang)(xiang)同的(de)(de)(de)情況下，取決(jue)于系(xi)(xi)統(tong)中(zhong)(zhong)性點(dian)的(de)(de)(de)工作方式，即中(zhong)(zhong)性點(dian)接(jie)地(di)(di)方式。在有效(xiao)(xiao)接(jie)地(di)(di)系(xi)(xi)統(tong)中(zhong)(zhong)，單(dan)相(xiang)(xiang)(xiang)接(jie)地(di)(di)故(gu)障(zhang)(zhang)線路(lu)會被迅速切除(chu)，防止(zhi)事故(gu)擴大，這對于110kV及(ji)(ji)以(yi)上(shang)的(de)(de)(de)輸變電(dian)(dian)(dian)網絡來說是(shi)合(he)適的(de)(de)(de)。35kV及(ji)(ji)以(yi)下中(zhong)(zhong)壓輸配電(dian)(dian)(dian)系(xi)(xi)統(tong)，由(you)于對供電(dian)(dian)(dian)可(ke)靠(kao)性要(yao)求高，則采用(yong)了中(zhong)(zhong)性點(dian)非有效(xiao)(xiao)接(jie)地(di)(di)方式，或(huo)稱(cheng)小電(dian)(dian)(dian)流接(jie)地(di)(di)方式，對于發(fa)生(sheng)幾率較高的(de)(de)(de)單(dan)相(xiang)(xiang)(xiang)接(jie)地(di)(di)故(gu)障(zhang)(zhang)，不(bu)會產生(sheng)危及(ji)(ji)人(ren)身、設備和系(xi)(xi)統(tong)安全(quan)的(de)(de)(de)短路(lu)電(dian)(dian)(dian)流，并具(ju)有瞬時(shi)性單(dan)相(xiang)(xiang)(xiang)接(jie)地(di)(di)故(gu)障(zhang)(zhang)自愈能力(li)，系(xi)(xi)統(tong)的(de)(de)(de)線電(dian)(dian)(dian)壓仍然對稱(cheng)，可(ke)以(yi)保(bao)持對用(yong)戶的(de)(de)(de)連續(xu)供電(dian)(dian)(dian)。

我國6~35kV中(zhong)(zhong)壓(ya)系統主要采用中(zhong)(zhong)性(xing)點不(bu)接地(di)(di)或經(jing)消弧線圈接地(di)(di)的(de)非有效接地(di)(di)方式，提高了中(zhong)(zhong)壓(ya)系統的(de)供電(dian)(dian)(dian)可(ke)靠性(xing)。但另(ling)一方面，這種接地(di)(di)方式也給中(zhong)(zhong)壓(ya)輸(shu)配電(dian)(dian)(dian)系統帶來了一些問題，主要是單(dan)相(xiang)接地(di)(di)時會引起(qi)弧光過(guo)電(dian)(dian)(dian)壓(ya)及諧振過(guo)電(dian)(dian)(dian)壓(ya)。特別對(dui)于較(jiao)高倍數的(de)間(jian)歇性(xing)弧光接地(di)(di)過(guo)電(dian)(dian)(dian)壓(ya)，如不(bu)能(neng)及時消除，可(ke)能(neng)造(zao)成(cheng)避雷器熱(re)崩潰、電(dian)(dian)(dian)纜放炮、電(dian)(dian)(dian)壓(ya)互感器故障、絕(jue)緣閃絡等各類事(shi)故，引發第二點接地(di)(di)造(zao)成(cheng)危(wei)害較(jiao)大的(de)相(xiang)間(jian)事(shi)故。

這(zhe)些事故(gu)(gu)表明(ming)中(zhong)壓系統(tong)中(zhong)性(xing)(xing)(xing)點(dian)(dian)(dian)非有(you)效(xiao)(xiao)接(jie)地(di)(di)方(fang)(fang)式會(hui)(hui)給系統(tong)電(dian)氣設備(bei)的(de)運行(xing)安(an)全帶(dai)來一(yi)些問(wen)題。這(zhe)些問(wen)題如果不能(neng)有(you)效(xiao)(xiao)解決(jue)，用戶就(jiu)會(hui)(hui)在(zai)供(gong)電(dian)可(ke)靠性(xing)(xing)(xing)和運行(xing)安(an)全性(xing)(xing)(xing)兩者(zhe)間進行(xing)選(xuan)擇(ze)，也就(jiu)是中(zhong)性(xing)(xing)(xing)點(dian)(dian)(dian)接(jie)地(di)(di)方(fang)(fang)式的(de)選(xuan)擇(ze)。多年(nian)的(de)運行(xing)經驗(yan)表明(ming)，在(zai)中(zhong)壓系統(tong)選(xuan)擇(ze)有(you)效(xiao)(xiao)接(jie)地(di)(di)方(fang)(fang)式會(hui)(hui)顯著(zhu)地(di)(di)降低供(gong)電(dian)可(ke)靠性(xing)(xing)(xing)。因(yin)此保持中(zhong)性(xing)(xing)(xing)點(dian)(dian)(dian)非有(you)效(xiao)(xiao)接(jie)地(di)(di)方(fang)(fang)式提(ti)高供(gong)電(dian)可(ke)靠性(xing)(xing)(xing)的(de)優點(dian)(dian)(dian)同時解決(jue)這(zhe)種接(jie)地(di)(di)方(fang)(fang)式帶(dai)來的(de)問(wen)題是近年(nian)來中(zhong)壓系統(tong)的(de)一(yi)個主要研究課題。解決(jue)這(zhe)一(yi)問(wen)題的(de)關鍵在(zai)于準(zhun)確的(de)故(gu)(gu)障選(xuan)線和有(you)效(xiao)(xiao)的(de)后續處理。在(zai)準(zhun)確確定故(gu)(gu)障支路的(de)基礎上，根據(ju)故(gu)(gu)障支路負載的(de)重要性(xing)(xing)(xing)以及故(gu)(gu)障的(de)性(xing)(xing)(xing)質來靈活、有(you)效(xiao)(xiao)地(di)(di)確定故(gu)(gu)障的(de)處理方(fang)(fang)式，形成系統(tong)解決(jue)方(fang)(fang)案。

目前市場上廣泛(fan)使用的(de)小電流選(xuan)線(xian)方式(shi)往往受到接地(di)點阻抗變化范(fan)圍大(da)、工況復(fu)雜、零(ling)序電流信號(hao)弱、電磁干擾強等各種因素的(de)影響，難以快速、準確地(di)選(xuan)出發生單相接地(di)故障支路(lu)，選(xuan)線(xian)準確率(lv)較低。
