Abstract
The ultra-high frequency (UHF) method is a kind of online monitoring of partial discharge signal. It has the advantages of high sensitivity, strong anti-interference ability, and has been widely used. Therefore, an external composite spiral antenna sensor is designed for partial discharge detection of gas insulated switchgear (GIS). The composite spiral antenna adopts the equiangular spiral antenna and archimedes spiral composite structure, terminal uses the butterfly vibrator loads, the metal back cavity, ultra broadband barron, can satisfy the requirement of the antenna miniaturization. The size of UHF sensor is 120mm $\times 90\text{mm}\times 75\text{mm}$, its standing wave ratio is less than 2.5 among 1GHz-1.5GHz. And the gain above 1GHz is greater than 4dB. In the UHF band, it has good detection performance and multi-band selection characteristics.
