摘要

为探究电容器组连接件因材质因素而可能在运行中引起连接件过热的问题

本文根据等比缩放原理对不同材质的试品以及经导电膏处理后的试品进行了模拟接触试验。通过对两导体接触面接触不良以至发生放电的过程中接触面间可承受最大接触间隙值和其温度变化值进行统计分析

得出结论:铝-铝面接触可以有效地降低接触面之间发生接触不良放电的概率

因该种接触形式的温升相对于其他接触类型较慢

可以短时承受因连接件接触不良温度偏高的工况。

Abstract

For the study of overheat problem of the connection elements of capacitor bank in the operation due to material factor

in this paper

the simulation contact test for the sample with different materials and the sample with conductive grease treatment is performed. It is concluded throughout the statistical analysis of poor contact of two conductors and the maximum contact gap value and its temperature variation which can be withstood by the contact surface during discharge period that the contact of aluminum-aluminum surface can reduce the discharge probability due to poor contact between the contact surface

because of the temperature rise of this type of contact is slower than other contact type

and it can withstand high temperature for a short time due to poor contact of connection elements.
