、请妷夯ジ衅魇褂米⒁馐马棦匐妷夯ジ衅鞯亩卫@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(yīng)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。

AONE/A-ONE AUTOVALVE,AD40-20S1參考價 一般型不帶有斷相運轉(zhuǎn)保護裝置的熱繼電器動作特性整定電流倍數(shù)動作時間起始狀態(tài)1．0長期不動作1．2小于20min從熱態(tài)開始1．5小于2min從熱態(tài)開始6大于5s從冷態(tài)開始投入使用前，必須對熱繼電器的整定電流進行，以保證熱繼電器的整定電流與被保護電動機的額定電流匹配。
根據(jù)磁場轉(zhuǎn)速n1=60f/p的公式，n1下降，轉(zhuǎn)子轉(zhuǎn)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。
