Abstract
Aiming at the attenuation problem of partial discharge signal in the transmission of high voltage cable,a portable GSM short message communication repeater based on FPGA time domain reflectometry(TDR)method is designed.It is mainly used for data acquisition,filtering out narrow band interference,white noise and other interference in partial discharge,detecting accurate partial discharge signal and transmitting its amplitude.The characteristic information such as the average discharge time is fed back to the local detection device in the form of short messages,and a larger pulse is generated to replace the partial discharge signal reflected by the far end.Then the computer simulates the local signal noise environment for the denoising experiment.Finally,the experiment shows that this device not only enhances the strength of local signal,but also improves the positioning accuracy.The test results meet the requirements.关键词
