Development And Application Of Intelligent Interference Processor For Partial Discharge Testing

Partial discharge detection of charged transformer and reactor of high voltage electrical equipment is to determine the internal insulation equipment is one of the most important methods of the state,but the test field interference signal source and complex,to the personnel of technology and experience level is very high.At present,there are some limitations of the existing detection tech nology in the interference signal processing.In this kind of background,the research and analysis of the interference signal processing of the partial discharge test is carried out,and the direction of the paper is determined.This paper focuses on analyzing the mechanism of partial discharge,in-depth study of several common types of partial discharge,the interference in partial discharge detection signal sources,types and forms,and the suppression methods were investigated.On this basis,we propose to develop intelligent filtering anti-jamming processor,according to the comparison of signal recognition,matrix filtering technology for hardware system design and implementation of filtering algorithm,combined with the simulation of matrix filter digital filter,finally realizes the intelligent multi band filter,measurement on the maximum extent,guarantee the accuracy and reliability of the local discharge test.The debugging,testing and field test results show that the system is stable and the fil tering effect is obvious,and it can be applied in practical engineering,and has achieved good results.
