基于自激法的非接触式CVT介质损耗测量装置研究
Research on CVT dielectric loss measuring device based on self-excitation with non-contact mode
摘要
Abstract
The normal operation of CVT affects the stability of the whole power system directly.A CVT dielectric loss measuring system based on self-excitation with non-contact mode is presented in this paper.CVT's voltage and current waveforms are sampled synchronously by non-contact measuring platform.The wireless WiFi module is used to transmit the measured electrical parameters to the PC side.The harmonic analysis method is adopted to process the voltage and current signals on LabVIEW software platform,and the dielectric loss parameter (tanδ) is obtained by calculation.The test result shows that this method can effectively detect the dielectric loss and capacitance values of each capacitor in the CVT,display the voltage and current parameters,and can be used to measure the long-term insulating state of CVT.It can isolate the high voltage in the actual dielectric loss measurement,and has high safety and reliability.关键词
