摘　　要：CWB-35型穿墙套管是一种典型的电场具有强垂直分量的绝缘结构。本文针对一起CWB-35型穿墙套管内腔放电实例,通过解体检查和电场简化分析计算,确认是由于导体上的接触片与瓷套内壁的半导体釉层接触不良引起的,并及时进行了更换处理。Wall bushing has a strong vertical component of the electric field intensity.The wall bushing had cavity discharge that was caused by poor contact between the conductor contact pad and the semiconductor glaze on the inner surface of the wall bushing.This was confirmed through the disassembly inspection and the simplification analysis of the electric field.The wall bushing was replaced in time.
