Abstract

Partial discharge detection is an effective method for evaluating the insulation condition of cable accessories. Ultra-high-frequency method for detecting partial discharge has strong anti-interference ability. Therefore, a broadband, circularly polarized Archimedean planar spiral antenna is used as the partial discharge detection sensor. After determining the antenna parameters through theoretical calculations, simulate and design the antenna. Analyze the influence of different inner diameter values on antenna performance. Exponential gradient microstrip balun is added to achieve impedance matching between the antenna and the coaxial line, and a reflection cavity is added to achieve unidirectional radiation and gain improvement of the antenna. Based on parameter analysis, optimize the design of Archimedean planar spiral antenna and complete the physical production. The test results indicate that the designed Archimedean planar spiral antenna has a gain greater than 6dB and a VSWR less than 2. The performance of the antenna meets the requirements.
