Study on correction signal generating circuit suitable for partial discharge signal simulation
摘要
Abstract
According to the standard of partial discharge measurement GB /T 7354-2003/IEC 60270:2000, a device which the phase , amplitude and number of pulses are adjustable has been designed as a simulation source for the dis -charge quantity calibration in the detection process of partial discharge device .The simulation source is made by square wave generating circuit and signal controlling circuit .In this circuit, the square wave is generated by using chip HEF4046 BP; the signal control circuit consists phase shifting circuit , square wave transforming circuit and square wave duty cycle controlling circuit .In order to verify the feasibility of the circuit , the whole circuit is built . The experimental results show that the function of the traditional quantitative pulse device is improved , the analog source can effectively output the PD signal in a variety of situations .关键词
