摘要

高压直流输电系统大量使用户外电力电容器进行无功补偿和滤波

接线柱连接失效故障日益凸显

通过分析目前普遍使用铜制金具的缺陷

认为发热主要原因是导线与线夹容易被氧化腐蚀等

本文设计了新型的铝制金具

可以避免铜制金具的缺点。

Abstract

A large number of outdoor power capacitors are used for reactive power compensation and filtering in HVDC transmission system and such fault as connection failure of wiring terminal becomes more prominent. It is thought

through analyzing the defects of copper metal fittings common used at present

that the main reason of heating is due to oxidization and corrosion of wire and clamp. In this paper

a new type of aluminous metal fittings is designed

which can avoid the defects of copper fittings.
