摘要
介绍了一种快速消除有害电势接线装置的研究,给出了有害电势产生和影响的分析以及接线装置的具体电气设计方案,该装置利用短路放电原理,使测试绕组自身短路放电,能快速将绕组测试端的电势降低到5V以下,较好地解决了有害电势对于电阻测试仪器设备造成的损害。
This article mainly introduced a device to eliminate the electrical potential of the motor winding. Based on both the research of the dangerous electrical potential sources and the testing in the laboratory, this device was able to reduce the harmful voltage occurring between the winding into 5V in a rapid way, which provided a good solution to protect the resistance meters from damages due to the high voltage.
