高压绝缘在线监控仪在高压电机运行中的应用

Application of High Voltage Insulation Online Monitoring Instrument in the Operation of High-voltage Motor

电力系统及电气设备的故障大部分是由于绝缘的损坏而引起。衡量电气设备绝缘的好与坏,目前只有在停电的情况下用直流摇表(兆欧表)来判定。本文研究了一种BTS-IRT高压绝缘在线监控仪方法,利用高压电阻隔离作用,可直接安装在高压电机的开关柜内,实现高压电机绝缘电阻的在线测量(BTS-IRT高压绝缘在线监控仪以下简称监控仪)。

Faults in power systems and electrical equipment are mostly caused by insulation damage.Only in the event of power failure with DC rocking meter(mega meter)can determine and measure the good or bad insulation of electrical equipment.In this paper,a method of BTS-IRT high voltage insulation online monitoring instrument is studied.It can be directly installed in the switchgear of high voltage motor by using the function of high voltage resistance isolation and online measurement of insulation resistance of high volt.age motor can be achieved(BTS-IRT high voltage insulation online monitoring instrument,hereinafter re.ferred to as"monitoring equipment").
