GIS盆式绝缘子均压环特高频接收特性研究
Research on Ultra-high Frequency Receiving Characteristic of GIS Basin-type Insulator Grading Ring
摘要
Abstract
With mass application of shielding ring basin-type insulator and constant miniaturization of equipment size,utiliza-tion of gas insulated metal-enclosed switchgear partial discharge ultra-high frequency sensor is greatly restricted and PD UHF detection is becoming difficult day by day. Aiming at above problems,regarding basin-type insulator grading ring as UHF aerial,relationship between loop aerial and factors such as PD apparent discharge magnitude,sensor position and grounding mode was tested. Meanwhile,frequency response characteristics of various UHF sensors were compared and analyzed. It was considered that GIS basin-type insulator grading ring was provided with good UHF receiving characteristic and was feasi-ble to be used for testing GIS PD as UHF aerial.关键词
