中電(dian)(dian)氣設備選(xuan)擇(ze)(ze)不(bu)當造成的(de)常見錯誤：生產過程中交流接(jie)觸(chu)器(qi)的(de)體積選(xuan)擇(ze)(ze)不(bu)當，不(bu)同組的(de)插(cha)座控制電(dian)(dian)路安裝了相(xiang)同體積的(de)交流接(jie)觸(chu)器(qi)，三相(xiang)負(fu)載的(de)差異(yi)不(bu)完全考慮過的(de)。在平(ping)衡(heng)狀態下，不(bu)能在所有正常模型中選(xuan)擇(ze)(ze)某些組的(de)輸出交流接(jie)觸(chu)器(qi)的(de)電(dian)(dian)流水(shui)平(ping)。基本上，電(dian)(dian)流水(shui)平(ping)是通過一(yi)個步驟(zou)選(xuan)擇(ze)(ze)的(de)，該步驟(zou)會導致(zhi)交流接(jie)觸(chu)器(qi)在高溫天(tian)氣下運行期間燒斷。

根(gen)據電(dian)(dian)(dian)氣設備的(de)接(jie)線規定(ding)，接(jie)線盒可(ke)安(an)裝在(zai)封閉(bi)或半封閉(bi)的(de)金屬外殼中或屏幕上，以(yi)(yi)形成配電(dian)(dian)(dian)室設備。如果一(yi)切正常，可(ke)以(yi)(yi)使用(yong)手(shou)或控制開(kai)(kai)關連接(jie)或斷(duan)開(kai)(kai)電(dian)(dian)(dian)源電(dian)(dian)(dian)路(lu)。常見(jian)的(de)錯誤或異常取決于家用(yong)電(dian)(dian)(dian)器的(de)維(wei)護，以(yi)(yi)斷(duan)開(kai)(kai)電(dian)(dian)(dian)路(lu)或警報(bao)。識別儀(yi)可(ke)以(yi)(yi)在(zai)信息模式下顯示各種主(zhu)要(yao)參(can)數，還可(ke)以(yi)(yi)調整某(mou)些電(dian)(dian)(dian)氣設備的(de)主(zhu)要(yao)參(can)數，并提醒或發出所有(you)正常工作設置的(de)偏差信號。常用(yong)于發電(dian)(dian)(dian)，配電(dian)(dian)(dian)和變電(dian)(dian)(dian)站。

涉及電源系統中發電，傳輸，分配，轉換和功耗中的接通和斷開，控制或保護的作用。高壓配電柜用(yong)作電(dian)(dian)壓(ya)(ya)(ya)(ya)等級在3.6 kV~550 kV的電(dian)(dian)氣產品(pin)作為高(gao)(gao)壓(ya)(ya)(ya)(ya)隔離(li)開(kai)關(guan)，有接地開(kai)關(guan)，高(gao)(gao)壓(ya)(ya)(ya)(ya)斷路器(qi)，自動高(gao)(gao)壓(ya)(ya)(ya)(ya)重(zhong)合和斷開(kai)裝(zhuang)置，高(gao)(gao)壓(ya)(ya)(ya)(ya)操作機(ji)構(gou)，防(fang)爆高(gao)(gao)壓(ya)(ya)(ya)(ya)配電(dian)(dian)裝(zhuang)置和高(gao)(gao)壓(ya)(ya)(ya)(ya)開(kai)關(guan)柜(ju)等不同類別。通(tong)常(chang)，連接到系(xi)統主母線的電(dian)(dian)容器(qi)柜(ju)用(yong)于中央無功功率補償，并(bing)(bing)且(qie)通(tong)常(chang)與輸(shu)入柜(ju)并(bing)(bing)聯安裝(zhuang)（系(xi)統具(ju)有PT柜(ju)，應為高(gao)(gao)壓(ya)(ya)(ya)(ya)系(xi)統，而低(di)(di)壓(ya)(ya)(ya)(ya)系(xi)統沒(mei)有PT柜(ju)- PT柜(ju)相(xiang)當于降低(di)(di)變壓(ya)(ya)(ya)(ya)器(qi)，只需要低(di)(di)壓(ya)(ya)(ya)(ya)變壓(ya)(ya)(ya)(ya)器(qi)，但(dan)是電(dian)(dian)容器(qi)柜(ju)很少用(yong)于高(gao)(gao)壓(ya)(ya)(ya)(ya)系(xi)統中，并(bing)(bing)且(qie)高(gao)(gao)壓(ya)(ya)(ya)(ya)電(dian)(dian)容器(qi)很難制造，并(bing)(bing)且(qie)通(tong)常(chang)在低(di)(di)壓(ya)(ya)(ya)(ya)側進行集中補償。
