高压电机定子绕组的超低频耐压试验与遥控

Extra Low Frequency Voltage Withstand Test of Motor Stator Winding of HV Generator and Remote Control

超低频0．1Hz交流耐压试验与工频交流耐压试验，当合理确定等价系数β后是完全等价的．超低频0．1Hz交流耐压试验，有设备容量小、灵巧方便、相对延长试品电机寿命并可代替直流耐压试验的优点，应大力推广．现介绍研制的超低频0.1Hz耐压试验装置，采用遥控的交流耐压试验，根本上解决了高压试验人员的安全．遥控应推广至高压试验与测量中．

if thc cquivalcnt cocfflcicnt gis rationally cltermincd the test of extra low frcqucncy 0.1Hz Ac voltagc-withstund is totally cquialcnt with the tcst of 50 HZ Ac voltage-withstand the test of 0.1 Hz Ac voltaage-withstand has the advantage of flcxibility and low size of cquipment,also it could prolong the scrvicc lifc of motor so it has a promising future. The afticle describcs the testing cqquipment of cxtra frcqucncy 0.1 HZ voltagc-withstand and the remotc control of Ac voltagc-withstand test, which rcdically solve the problem of the safcty of high voltage testing worker. The rcmote coutrol should be developpcd in thc tcshng and measure of high voltage.
