Positioning device and system of partial?discharge signal source in gas?insulated?substation (GIS)

The utility model discloses a positioning device and system of a partial?discharge signal source in a gas?insulated?substation (GIS). The positioning device of the partial?discharge signal source in the gas?insulated?substation comprises a first detector for detecting the partial discharge signal of the partial discharge signal source to obtain a first signal; a second detector for detecting the partial discharge signal of the partial discharge signal source to obtain a second signal; a receiver for receiving the first signal and the second signal in the wireless communication way and determining the position of the partial discharge signal source according to the first signal and the second signal. The positioning device and system solve the problem of the prior art that the structure of the GIS partial discharge positioning system is complicated, and furthermore the structure of the GIS partial discharge positioning system is simplified.
