摘要
针对变压器套管状态检修中出现的带电检测接口难点问题,统计分析了浙江电网变压器套管厂家分布情况,对主要的9个厂家15种套管末屏接地方式进行了研究。从信号引出的角度,将这15种末屏接地结构分为插拔式、螺纹式和特殊式3种结构,可为套管带电检测接口的研究提供参考。
Aiming at the difficulty in live detection interface in condition-based maintenance of transformer bushing, the paper statistically analyzes distribution of transformer bushing manufacturers in Zhejiang power grid and investigates 15 earthing modes of bushing tap from 9 manufacturers. The 15 earthing structures are divided into plug-insert type, screw type and special type in terms of signal eduction, which provides refer- ence for research on live detection interface of bushing.
