摘要(Abstract)：

实行变压器套管状态检修,需合适的带电检测接口,对浙江电网主要变压器套管型式及接地方式做了统计,提出并解决了套管末屏适配器研究中的信号引出、防水密封、防开路保护等3个关键问题,研制了应用于8个主要生产厂家的12种末屏接地结构的接口适配器,研制的套管在线监测接口适配器适用范围可覆盖浙江电网98%左右的在运变压器。
It needs proper live detection interface to implement condition-based maintenance(CBM) of transformer bushing.The paper analyses types and earthing mode of Zhejiang power grid′s main transformer bushings;furthermore,it proposes and handles signal induction,waterproof and open circuit protection in research of bushing tap adapter.Twelve end screen grounded interface adapters applied in eight manufacturers are developed,and the online monitoring interface adapter of transformer bushing can be used in 98 percent operating transformers in Zhejiang power grid.
