中電(dian)氣設備選(xuan)擇(ze)不當(dang)造(zao)成的常見錯(cuo)誤：生產(chan)過程中交(jiao)(jiao)流(liu)(liu)接觸(chu)器的體積選(xuan)擇(ze)不當(dang)，不同組的插座控制電(dian)路安(an)裝了相(xiang)同體積的交(jiao)(jiao)流(liu)(liu)接觸(chu)器，三相(xiang)負載的差異不完全考慮過的。在(zai)(zai)平衡狀(zhuang)態下(xia)，不能在(zai)(zai)所有正常模(mo)型中選(xuan)擇(ze)某(mou)些(xie)組的輸出交(jiao)(jiao)流(liu)(liu)接觸(chu)器的電(dian)流(liu)(liu)水平。基本(ben)上，電(dian)流(liu)(liu)水平是通過一個步驟選(xuan)擇(ze)的，該步驟會導致交(jiao)(jiao)流(liu)(liu)接觸(chu)器在(zai)(zai)高溫天氣下(xia)運行期間(jian)燒斷。
