| 摘 要： | 为及时掌握电容式电压互感器(CVT)的运行状态,对三相和单相CVT采集电压信号进行实时监测告警并设定了越限告警值。在加压绕组的选择、所加电压的确定二个方面提出了自励法进行叠装式CVT的介损试验方法。通过电压检测并辅以介损试验,可有效监控CVT的绝缘状态,确保设备的安全运行。

| Abstract: | Voltage signal is acquired from three-phase and single-phase capacitor voltage transformers（CVT） for real-time monitoring alarm and out-of-limit alarm value is set in order to obtain the running state of CVT timely.Self-excitation method is proposed for superposition CVT dielectric loss test from the aspects of the selection of supercharged wind and determination of voltage applied.CVT insulation can be effectively monitored to ensure safe operation of equipment by voltage test and dielectric loss test. |
