摘要
固体环网柜应具备全绝缘性,所有裸露的电导体必须用绝缘堵头封堵保护。对12 kV固体绝缘环网柜堵头的安装困难且界面可能滞留气泡的问题进行研究,分析了绝缘堵头的安装位置和绝缘结构以及问题产生的原因,并设计出新型的堵头,电场仿真计算验证了所提解决方案的可行性。
The solid ring main unit should be provided with all insulation and all the exposed electric conductors have to be protected by insulation plugs.This paper researched on the problems of possibly retention bubbles on interface and the installation difficulty of 12 kV solid-insulated ring main units plugs,analyzed the installation location of insulation plugs,insulation structure and causes of problems,and designed the new-type plugs.The electric field simulating calculation verifies the feasibility of the mentioned solution.
