摘要
通过两起电容式电压互感器(CVT)红外测温实例和两起CVT二次电压降低原因分析实例,采用红外线测温和监测CVT二次电压的方法,得出CVT红外线测温和监测二次电压方法可有效发现CVT早期故障,实现对CVT绝缘性能和电气性能的带电监测,防止CVT事故扩大,可实现CVT不停电预试或延长预试周期。
In this paper, through two infrared thermometry examples of capacitor voltage transformers （CVT） and cause analysis example of secondary voltage reduction of two CVTs, it is concluded that infrared temperature measurement and monitoring of secondary voltage of CVT can find effectively the fault of CVT at earlier stage, achieve live monitoring of insulation and electrical performance of CVT, prevent development of the fault and realize live precaution test or extend precaution test inter- val of CVT.
