电压互感器现场检查仪的设计

Design of Field Inspection Instrument for Voltage Transformer

电压互感器因多种原因无法实现有针对性的现场检测,给运行带来隐患。本文基于电压互感器的负载特性,提出一种新型的现场检查方法,能够对电压互感器的运行状况做出定性的判别,并在此基础上完成了电压互感器现场检查仪的设计。现场测试数据表明,仪器实现了预设的功能。

Due to many reasons, The objective field inspection for voltage transformer can＇t be carried out, which will cause incipient faults. This paper puts forward a new field inspection method, it can identify the state of voltage transformer, and the field inspection instrument is made successfully based on it. The date of field inspection shows that the function of device has been realized.
