電(dian)(dian)(dian)工(gong)(gong)(gong)既(ji)是一門技術活，也是一門體(ti)力(li)活。許多(duo)人并不知道電(dian)(dian)(dian)工(gong)(gong)(gong)背后的(de)(de)(de)艱辛(xin)，爬高塔容易摔傷(shang)，高溫天全副(fu)勞保(bao)裝作業，電(dian)(dian)(dian)力(li)搶修三天不睡(shui)覺(jue)，操(cao)作不當(dang)電(dian)(dian)(dian)弧傷(shang)人，這些誰看到了(le)?所以，基(ji)層出身的(de)(de)(de)老板(ban)，都(dou)會尊重(zhong)電(dian)(dian)(dian)工(gong)(gong)(gong)。電(dian)(dian)(dian)工(gong)(gong)(gong)清(qing)閑，設備安全，電(dian)(dian)(dian)工(gong)(gong)(gong)就是機電(dian)(dian)(dian)設備的(de)(de)(de)保(bao)護(hu)神。

高低壓配電(dian)柜廠家談：電(dian)工對于企業的(de)重要性。現在(zai)工廠，電(dian)控模塊化，出(chu)了故障，換換部件就行，維修電(dian)工顯(xian)得越(yue)來越(yue)沒用了。這是很膚淺的(de)認識。

　溫(wen)度(du)保護(hu)動作是(shi)由(you)于開關柜(ju)變(bian)(bian)壓器溫(wen)度(du)超過(guo)(guo)(guo)設定值(zhi)。如(ru)果設置(zhi)正確，必(bi)須嘗試降(jiang)低(di)變(bian)(bian)壓器的溫(wen)度(du)。通(tong)過(guo)(guo)(guo)通(tong)風降(jiang)低(di)環(huan)境溫(wen)度(du)，通(tong)過(guo)(guo)(guo)減載降(jiang)低(di)變(bian)(bian)壓器溫(wen)升。如(ru)果設置(zhi)值(zhi)太小，可以增(zeng)加設置(zhi)值(zhi)。通(tong)過(guo)(guo)(guo)以上幾種方法打(da)開溫(wen)度(du)觸點，接(jie)通(tong)開關柜(ju)電源。

高壓開關柜突然跳閘故障的處理

1. 當(dang)變(bian)(bian)壓(ya)器(qi)發(fa)生(sheng)內部(bu)(bu)故障或過(guo)載時，會發(fa)生(sheng)氣體和(he)溫度保護作(zuo)用。如(ru)果重氣動作(zuo)是由(you)變(bian)(bian)壓(ya)器(qi)內部(bu)(bu)故障引起的，則必須對(dui)變(bian)(bian)壓(ya)器(qi)進行修理。如(ru)果新的移動、換(huan)料(liao)變(bian)(bian)壓(ya)器(qi)發(fa)生(sheng)輕氣動作(zuo)，則可以(yi)在(zai)釋放內部(bu)(bu)氣體后(hou)繼續(xu)投入運行。

2. 快(kuai)速(su)斷路，應檢查母線(xian)、變壓(ya)器及相關線(xian)路，找(zhao)出短路故(gu)(gu)障(zhang)點，排(pai)除(chu)故(gu)(gu)障(zhang)后再通電。

3. 過電流(liu)繼電器(qi)動(dong)作使開關跳閘，因為在線(xian)路上負(fu)載過大。供(gong)電前，應(ying)考慮(lv)減少或平衡負(fu)荷(he)，防(fang)止供(gong)電后再次(ci)跳閘。

4.過(guo)電(dian)(dian)流和快斷(duan)保護使開(kai)關跳閘后(hou)，繼電(dian)(dian)器(qi)可復(fu)位。這種特(te)性可以從溫度和氣體保護中區分出(chu)來。
