Miniaturization Study of Four-arm Positive Spin Antenna for Local Discharge Detection
摘要
Abstract
For high voltage electrical equipment such as transformer,gas insulation combination(GIS),medium voltage switchgear equipment local discharge(PD)high frequency signal high sensitivity detection requirements,to solve the existing high frequency spiral antenna(UHF)such as plane angle spiral,archimedes spiral external installation single polarization direction,large size,narrow detection band,weak anti-interference ability and low sensitivity,the four arm positive spin antenna miniaturization research.First,the HFSS simulation determines the optimal size of the antenna in the operating frequency band.Under the verification of the port parameters of the antenna and the radiation performance of the antenna,that is,the full polarization characteristics of the four-arm antenna and the S11 parameters less than-10dB,the VSWR voltage standing wave ratio less than 3 dB,and the Rogers RT/duroid 5880 with dielectric constant of 2.2 is selected as the medium substrate.Finally,the designed antenna PCB is tested in the four simulated local discharge experimental environments.The results show that the internal air gap discharge,free metal particle discharge and discharge along the surface of the four-arm positive spiral antenna can detect the pulse signal and perfectly retain the characteristic information of the four discharge information,and the size is controlled within 200 cm,the designed antenna can be used in the complex electrical equipment environment.关键词
