一、產品概述

在(zai)電(dian)(dian)(dian)力(li)系(xi)(xi)(xi)(xi)統(tong)中(zhong)(zhong)(zhong)(zhong)，單(dan)相接(jie)地(di)(di)故(gu)(gu)(gu)障(zhang)約(yue)占全(quan)(quan)部故(gu)(gu)(gu)障(zhang)的85%,而且這些(xie)單(dan)相接(jie)地(di)(di)故(gu)(gu)(gu)障(zhang)中(zhong)(zhong)(zhong)(zhong)，85%以上(shang)是瞬(shun)時(shi)的和(he)可以恢復的。電(dian)(dian)(dian)力(li)系(xi)(xi)(xi)(xi)統(tong)運行的安全(quan)(quan)性和(he)供(gong)電(dian)(dian)(dian)的可靠性，在(zai)其它(ta)條件相同的情況下，取(qu)決于(yu)系(xi)(xi)(xi)(xi)統(tong)中(zhong)(zhong)(zhong)(zhong)性點的工作(zuo)方式(shi)，即(ji)中(zhong)(zhong)(zhong)(zhong)性點接(jie)地(di)(di)方式(shi)。在(zai)有效(xiao)接(jie)地(di)(di)系(xi)(xi)(xi)(xi)統(tong)中(zhong)(zhong)(zhong)(zhong)，單(dan)相接(jie)地(di)(di)故(gu)(gu)(gu)障(zhang)線路會被迅(xun)速切(qie)除，防止事故(gu)(gu)(gu)擴大，這對(dui)于(yu)110kV及(ji)以上(shang)的輸變電(dian)(dian)(dian)網絡來(lai)說是合適的。35kV及(ji)以下中(zhong)(zhong)(zhong)(zhong)壓(ya)輸配電(dian)(dian)(dian)系(xi)(xi)(xi)(xi)統(tong)，由于(yu)對(dui)供(gong)電(dian)(dian)(dian)可靠性要求高，則采(cai)用了中(zhong)(zhong)(zhong)(zhong)性點非有效(xiao)接(jie)地(di)(di)方式(shi)，或稱小電(dian)(dian)(dian)流(liu)接(jie)地(di)(di)方式(shi)，對(dui)于(yu)發生幾率較高的單(dan)相接(jie)地(di)(di)故(gu)(gu)(gu)障(zhang)，不會產生危(wei)及(ji)人身、設備和(he)系(xi)(xi)(xi)(xi)統(tong)安全(quan)(quan)的短路電(dian)(dian)(dian)流(liu)，并具有瞬(shun)時(shi)性單(dan)相接(jie)地(di)(di)故(gu)(gu)(gu)障(zhang)自愈能力(li)，系(xi)(xi)(xi)(xi)統(tong)的線電(dian)(dian)(dian)壓(ya)仍然對(dui)稱，可以保(bao)持對(dui)用戶的連續供(gong)電(dian)(dian)(dian)。

我國6~35kV中壓系(xi)(xi)統(tong)主(zhu)要采(cai)用中性點(dian)不接(jie)地(di)或(huo)經消弧線圈接(jie)地(di)的(de)非有效接(jie)地(di)方(fang)式，提高了中壓系(xi)(xi)統(tong)的(de)供電(dian)可靠(kao)性。但另一方(fang)面，這種接(jie)地(di)方(fang)式也給中壓輸配電(dian)系(xi)(xi)統(tong)帶來了一些問題，主(zhu)要是單相接(jie)地(di)時會引起弧光過(guo)電(dian)壓及諧振(zhen)過(guo)電(dian)壓。特別對于較高倍數的(de)間歇性弧光接(jie)地(di)過(guo)電(dian)壓，如不能及時消除，可能造成避雷器(qi)(qi)熱(re)崩(beng)潰、電(dian)纜(lan)放炮、電(dian)壓互感器(qi)(qi)故障、絕緣閃絡(luo)等(deng)各類事(shi)故，引發第二點(dian)接(jie)地(di)造成危害較大(da)的(de)相間事(shi)故。

這(zhe)些(xie)事故(gu)(gu)(gu)表(biao)明中(zhong)壓系(xi)(xi)統(tong)(tong)中(zhong)性(xing)點(dian)(dian)非(fei)有(you)效(xiao)接地(di)方(fang)(fang)式(shi)會給系(xi)(xi)統(tong)(tong)電(dian)氣設備的(de)(de)運行(xing)安(an)(an)全帶(dai)來(lai)一些(xie)問(wen)(wen)題(ti)。這(zhe)些(xie)問(wen)(wen)題(ti)如果不能有(you)效(xiao)解(jie)(jie)決(jue)(jue)，用戶就會在(zai)(zai)供(gong)電(dian)可(ke)靠性(xing)和運行(xing)安(an)(an)全性(xing)兩者間(jian)進行(xing)選(xuan)擇，也就是(shi)中(zhong)性(xing)點(dian)(dian)接地(di)方(fang)(fang)式(shi)的(de)(de)選(xuan)擇。多年(nian)的(de)(de)運行(xing)經驗表(biao)明，在(zai)(zai)中(zhong)壓系(xi)(xi)統(tong)(tong)選(xuan)擇有(you)效(xiao)接地(di)方(fang)(fang)式(shi)會顯(xian)著地(di)降(jiang)低供(gong)電(dian)可(ke)靠性(xing)。因此保持中(zhong)性(xing)點(dian)(dian)非(fei)有(you)效(xiao)接地(di)方(fang)(fang)式(shi)提高供(gong)電(dian)可(ke)靠性(xing)的(de)(de)優點(dian)(dian)同時(shi)解(jie)(jie)決(jue)(jue)這(zhe)種(zhong)接地(di)方(fang)(fang)式(shi)帶(dai)來(lai)的(de)(de)問(wen)(wen)題(ti)是(shi)近年(nian)來(lai)中(zhong)壓系(xi)(xi)統(tong)(tong)的(de)(de)一個主要研(yan)究課題(ti)。解(jie)(jie)決(jue)(jue)這(zhe)一問(wen)(wen)題(ti)的(de)(de)關鍵在(zai)(zai)于準(zhun)確(que)(que)的(de)(de)故(gu)(gu)(gu)障(zhang)(zhang)(zhang)選(xuan)線和有(you)效(xiao)的(de)(de)后續處理。在(zai)(zai)準(zhun)確(que)(que)確(que)(que)定(ding)故(gu)(gu)(gu)障(zhang)(zhang)(zhang)支路的(de)(de)基(ji)礎上(shang)，根(gen)據故(gu)(gu)(gu)障(zhang)(zhang)(zhang)支路負載的(de)(de)重要性(xing)以及故(gu)(gu)(gu)障(zhang)(zhang)(zhang)的(de)(de)性(xing)質來(lai)靈活、有(you)效(xiao)地(di)確(que)(que)定(ding)故(gu)(gu)(gu)障(zhang)(zhang)(zhang)的(de)(de)處理方(fang)(fang)式(shi)，形成系(xi)(xi)統(tong)(tong)解(jie)(jie)決(jue)(jue)方(fang)(fang)案。

目前(qian)市(shi)場上廣泛(fan)使用的小電流(liu)選(xuan)(xuan)線方式往往受到接地點阻抗變化(hua)范圍大、工況復雜(za)、零序電流(liu)信號(hao)弱、電磁干擾強等各種因素(su)的影響，難以(yi)快(kuai)速、準確地選(xuan)(xuan)出發生單相(xiang)接地故障支路，選(xuan)(xuan)線準確率(lv)較低(di)。
