AONE/A-ONE AUTOVALVE,AD40-20S1參考價　　用數(shù)字萬用表歐姆檔2K以下檔測量線圈，看線圈是否斷路,如果斷路證明線圈壞。用萬用表歐姆檔200測量常閉和常開（測量常開用手按住或者通電吸住）輔助觸點通不通，如果觸點不好，此時測量電阻是很大的。表明觸點不好，如果輔助觸點接有負載，測量電壓時，電壓會達不到額定電壓。　　上圖,是雙電容單相電動機接線盒上的接線圖，圖上清晰的反映了電動機主繞組、副繞組和電容的接線位置，你只需要按圖接進電源線，用連接片連接Z2和U2，UI和VI，電動機順轉，用連接片連接Z2和U1，U2和VI，電動機逆轉。用萬用表也容易區(qū)分6根線，阻值的是啟動繞組，阻值比較小的運行繞組，阻值為零的是離心開關。
　　⑶電壓互感器使用注意事項①電壓互感器的二次繞組不允許短路。因為一旦發(fā)生短路，二次繞組將產(chǎn)生一個很大的電流，導致一次繞組電流隨之激增，由此將燒壞互感器的繞組。②電壓互感器的二次繞組應當可靠接地。③電壓互感器的二次繞組阻抗不得小于規(guī)定值，以減小誤差。

　　根據(jù)磁場轉速n1=60f/p的公式，n1下降，轉子轉速也隨之下降，使風量減小，散熱不良，又會導致電機溫度上升。要使60HZ的電動機用于50HZ的電源上不，可采用降低電源電壓的方法來解決。以380伏電動機為例說明。
