APPARATUS FOR ACQUIRING PARTIAL DISCHARGE TIMING SIGNAL AND SYSTEM FOR SUPPRESSING PARTIAL DISCHARGE NOISE AND DETECTING PATIAL DISCHARGE INCLUDING THE SAME

摘要

The present invention relates to a partial discharge timing signal acquisition device which comprises: a proportional signal generation unit generating first and second proportional signals in accordance with an input signal; a first automatic yield adjustment unit performing automatic yield adjustment with respect to a partial discharge detection signal which is generated based on the first proportional signal and is fed back to an input end through at least one partial discharge capacitor; a second automatic yield adjustment unit performing automatic yield adjustment based on a partial discharge comparison signal which is generated based on the second proportional signal and is fed back to the input end; a timing noise removal unit generating a timing noise removal signal from which timing noise is removed based on the partial discharge detection signal and the partial discharge comparison signal; and a timing signal generation unit acquiring a partial discharge generation timing. According to a test result, the generation timing is generated upon generation of a partial discharge signal period when the partial discharge signal is generated, that is, the timing signal is generated at a point of time when generation is started, thereby precisely processing noise and acquiring partial discharge. Moreover, the present invention is intended to attain the effect thereof with a timing result.
