Title:
DEVICE AND METHOD FOR PROCESSING PARTIAL DISCHARGE
Document Type and Number:
WIPO Patent Application WO/2019/078602
Kind Code:
A1
Abstract:
This device for processing partial discharge includes: a proportional signal generation unit which generates a proportional signal which is proportional to the strength of an input signal; a transfer function generation unit which is positioned between an output end of the proportional signal generation unit and an input end of an automatic gain control unit, converts the proportional signal input to the input end on the basis of a reference voltage and a transfer function, and outputs a transfer function signal; the automatic gain control unit which performs automatic gain control when the transfer function signal is input; a partial discharge detection unit which generates an automatic gain control feedback signal through at least one RC parallel circuit to feedback the automatic gain control feedback signal to a feedback end of the automatic gain control unit, when an automatic gain control signal of the automatic gain control unit is input; and a partial discharge determination unit which filters an automatic gain control output signal on the basis of the reference voltage to generate a partial discharge determination signal, when the automatic gain control output signal of the automatic gain control unit is input.
