中電(dian)氣設備選擇(ze)不(bu)(bu)當造成的(de)常見錯誤：生產過(guo)程中交流接觸(chu)器(qi)(qi)的(de)體積(ji)選擇(ze)不(bu)(bu)當，不(bu)(bu)同組(zu)的(de)插座控制電(dian)路安裝了相同體積(ji)的(de)交流接觸(chu)器(qi)(qi)，三相負載的(de)差異不(bu)(bu)完全(quan)考慮過(guo)的(de)。在平衡(heng)狀(zhuang)態下，不(bu)(bu)能在所有正常模(mo)型中選擇(ze)某些(xie)組(zu)的(de)輸出交流接觸(chu)器(qi)(qi)的(de)電(dian)流水(shui)平。基本(ben)上，電(dian)流水(shui)平是通(tong)過(guo)一個步(bu)驟(zou)選擇(ze)的(de)，該步(bu)驟(zou)會導(dao)致交流接觸(chu)器(qi)(qi)在高溫天氣下運行期間燒斷。

根(gen)據電(dian)(dian)(dian)氣(qi)設(she)備(bei)的(de)(de)接(jie)(jie)線規定，接(jie)(jie)線盒可安裝在封閉或(huo)(huo)(huo)半(ban)封閉的(de)(de)金屬(shu)外殼中或(huo)(huo)(huo)屏幕上，以(yi)(yi)形成(cheng)配電(dian)(dian)(dian)室設(she)備(bei)。如果一(yi)切(qie)正常，可以(yi)(yi)使用(yong)手或(huo)(huo)(huo)控制開關連接(jie)(jie)或(huo)(huo)(huo)斷(duan)開電(dian)(dian)(dian)源電(dian)(dian)(dian)路。常見的(de)(de)錯誤(wu)或(huo)(huo)(huo)異(yi)常取決于家用(yong)電(dian)(dian)(dian)器(qi)的(de)(de)維護，以(yi)(yi)斷(duan)開電(dian)(dian)(dian)路或(huo)(huo)(huo)警報。識(shi)別儀可以(yi)(yi)在信息模式下顯示各種(zhong)主要(yao)參數(shu)，還可以(yi)(yi)調整(zheng)某些電(dian)(dian)(dian)氣(qi)設(she)備(bei)的(de)(de)主要(yao)參數(shu)，并提醒或(huo)(huo)(huo)發出(chu)所有正常工作(zuo)設(she)置(zhi)的(de)(de)偏差(cha)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)(yong)作電(dian)壓(ya)(ya)(ya)(ya)等(deng)級在3.6 kV~550 kV的電(dian)氣產品作為(wei)高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)隔離開關(guan)，有接地開關(guan)，高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)斷路(lu)器，自動高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)重(zhong)合和斷開裝置，高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)操(cao)作機(ji)構，防爆高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)配電(dian)裝置和高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)開關(guan)柜等(deng)不同類別。通常(chang)，連接到系(xi)統(tong)主母線的電(dian)容器柜用(yong)(yong)于中(zhong)(zhong)央無功功率補(bu)償，并且(qie)通常(chang)與輸入柜并聯安裝（系(xi)統(tong)具有PT柜，應為(wei)高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)系(xi)統(tong)，而低壓(ya)(ya)(ya)(ya)系(xi)統(tong)沒有PT柜- PT柜相當(dang)于降低變(bian)(bian)壓(ya)(ya)(ya)(ya)器，只(zhi)需要低壓(ya)(ya)(ya)(ya)變(bian)(bian)壓(ya)(ya)(ya)(ya)器，但(dan)是電(dian)容器柜很(hen)少用(yong)(yong)于高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)系(xi)統(tong)中(zhong)(zhong)，并且(qie)高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)電(dian)容器很(hen)難制造，并且(qie)通常(chang)在低壓(ya)(ya)(ya)(ya)側進行(xing)集中(zhong)(zhong)補(bu)償。
