中(zhong)電(dian)氣設備選(xuan)擇不當造成(cheng)的常見錯誤：生產過程中(zhong)交(jiao)流(liu)接觸(chu)器的體積(ji)選(xuan)擇不當，不同組(zu)的插座控制電(dian)路安裝了(le)相同體積(ji)的交(jiao)流(liu)接觸(chu)器，三(san)相負載(zai)的差異不完(wan)全考慮過的。在平衡狀態下，不能在所(suo)有正常模型(xing)中(zhong)選(xuan)擇某(mou)些組(zu)的輸出交(jiao)流(liu)接觸(chu)器的電(dian)流(liu)水(shui)平。基本上(shang)，電(dian)流(liu)水(shui)平是通過一個步驟(zou)選(xuan)擇的，該步驟(zou)會導(dao)致交(jiao)流(liu)接觸(chu)器在高溫天氣下運行期間(jian)燒斷。
