Device for GIS partial discharge detector is supplementary

The utility model provides a GIS partial discharge detector auxiliary device, is including setting up the first shield cover on GIS, install receiving antenna on the first shield cover, the signal reception module was connected to the other end in receiving antenna one end was in first shield cover, the signal amplification module is connected to the signal reception module, signal-radiation module is connected to the signal amplification module, the last emit antenna that connects of signal-radiation module, the signal reception module, signal amplification module and signal-radiation module installation are inside with the secondary shielding cover, emit antenna's free end leads to the external world through the flange of GIS shell. It can be in the more easy GIS partial discharge circumstances that detects in the external world, has guaranteed the safety of GIS operation, makes outside detection device more sensitive to GIS partial discharge
