中(zhong)電氣設備(bei)選擇不(bu)當(dang)造成(cheng)的(de)常(chang)見錯誤：生產過程(cheng)中(zhong)交(jiao)流接(jie)觸器(qi)的(de)體積選擇不(bu)當(dang)，不(bu)同(tong)組的(de)插座控(kong)制電路安裝了相同(tong)體積的(de)交(jiao)流接(jie)觸器(qi)，三相負載的(de)差(cha)異不(bu)完全考慮過的(de)。在平(ping)衡狀態下，不(bu)能(neng)在所(suo)有正常(chang)模(mo)型中(zhong)選擇某些(xie)組的(de)輸出交(jiao)流接(jie)觸器(qi)的(de)電流水(shui)平(ping)。基本上，電流水(shui)平(ping)是(shi)通過一個步(bu)驟選擇的(de)，該步(bu)驟會導致(zhi)交(jiao)流接(jie)觸器(qi)在高溫天氣下運行期間燒斷。

根(gen)據電(dian)(dian)(dian)(dian)氣設備(bei)的接(jie)線(xian)規(gui)定，接(jie)線(xian)盒可(ke)安(an)裝(zhuang)在封閉或(huo)半(ban)封閉的金屬(shu)外殼中或(huo)屏(ping)幕(mu)上(shang)，以(yi)(yi)(yi)形成配電(dian)(dian)(dian)(dian)室設備(bei)。如果一切正(zheng)常(chang)，可(ke)以(yi)(yi)(yi)使用(yong)手或(huo)控制開關(guan)連接(jie)或(huo)斷開電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)路。常(chang)見的錯誤或(huo)異常(chang)取決于家(jia)用(yong)電(dian)(dian)(dian)(dian)器的維護，以(yi)(yi)(yi)斷開電(dian)(dian)(dian)(dian)路或(huo)警報。識(shi)別儀(yi)可(ke)以(yi)(yi)(yi)在信息模式(shi)下顯示各種主要(yao)(yao)參數，還(huan)可(ke)以(yi)(yi)(yi)調整某些(xie)電(dian)(dian)(dian)(dian)氣設備(bei)的主要(yao)(yao)參數，并提醒或(huo)發(fa)出所有正(zheng)常(chang)工作設置的偏差信號。常(chang)用(yong)于發(fa)電(dian)(dian)(dian)(dian)，配電(dian)(dian)(dian)(dian)和變電(dian)(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。高壓配電柜用作電(dian)壓等級在(zai)3.6 kV~550 kV的電(dian)氣產品作為高(gao)壓隔離開(kai)關(guan)，有接(jie)地開(kai)關(guan)，高(gao)壓斷(duan)路器(qi)(qi)(qi)，自動高(gao)壓重合和(he)斷(duan)開(kai)裝置(zhi)，高(gao)壓操(cao)作機構，防爆高(gao)壓配電(dian)裝置(zhi)和(he)高(gao)壓開(kai)關(guan)柜等不同類別(bie)。通常，連接(jie)到系統(tong)主母線的電(dian)容(rong)器(qi)(qi)(qi)柜用于中(zhong)央(yang)無功功率補(bu)償，并(bing)且(qie)通常與輸入柜并(bing)聯(lian)安裝（系統(tong)具(ju)有PT柜，應為高(gao)壓系統(tong)，而低(di)(di)(di)壓系統(tong)沒有PT柜- PT柜相當于降低(di)(di)(di)變(bian)壓器(qi)(qi)(qi)，只需要低(di)(di)(di)壓變(bian)壓器(qi)(qi)(qi)，但是電(dian)容(rong)器(qi)(qi)(qi)柜很(hen)少用于高(gao)壓系統(tong)中(zhong)，并(bing)且(qie)高(gao)壓電(dian)容(rong)器(qi)(qi)(qi)很(hen)難制造，并(bing)且(qie)通常在(zai)低(di)(di)(di)壓側進行集中(zhong)補(bu)償。
