摘要
采用色谱试验、电气法局部放电、特高频在线局部放电、超声波局部放电与定位几种方法对500 kV变压器出现少量乙炔后进行试验,判断变压器的故障形式与位置,及时停电进行处理。并比较了各种方法的优越性和局限性,通过实际测试波形,给从事高压试验工作的人员提供第一手资料,有利于对设备放电性故障的诊断。
Through the experience of a little acetylene exiting in 500 kV transformer with chromatography test, electric partial discharge, ultra high frequency online partial discharge, supersonic partial discharge, location and other methods, the fault mode and position of transformer are determined, so as to put outage in time to treat, then the superiority and limitation of every methods are compared. By use of the practicality to test wave, the first hand materials may be supplied for the people who are engaged in high voltage testing, and is good at the discharged fault diagnosis of instruments.
