高压直流设备外绝缘采用合成绝缘的可行性

The feasibility of the composite insulation applied to HVDC equipment

叙述高压直流设备外绝缘采用瓷绝缘在直流下存在积污严重和易产生离子迁移使绝缘老化等问题,并对合成绝缘和瓷绝缘在直流作用下其特性进行对比研究。从理论分析和试验说明合成绝缘子具有优良的耐污闪性和耐候性,将其用于高压直流设备外绝缘是可行的。

This paper presents the problems on applying china insulation on HVDC equipment ,namely,serious contaminant and ion transfer leading insulation aging,and also introduces the study on the characteristic of composite insulation and china insulation under DC.It also explains the excellent anti-pollution flashover and anti-climate of the composite insulation by the experimental and theoretical analysis,and presents the feasibility of using composite insulation for HVDC equipment.
