摘要

高压断路器触指部位的仿真是热分析中的关键问题。各类高压电器的触指部位在稳态工作状态下往往是最高温升点

却因结构复杂而难以实现准确仿真分析。笔者以弹簧触指为核心部件

外加其他必要结构所构成的弹簧触指导电回路为对象

通过对发热、传热二者作用规律的合理分析和建模

提出了一个适用于弹簧触指温升的仿真分析方法。根据所提出的方法

笔者对弹簧触指样品进行了交、直流各4组稳态温升仿真

通过仿真计算结果和实验数据的对比

验证了仿真方法的正确性

对高压电器设计及其他复杂触头结构的温度场仿真具有一定的参考意义。

Abstract

Various contacts of high-voltage electrical apparatus always reach the highest temperature rise in steady operation state. However

the analysis of contacts is inconvenience because of the complex structure. This paper assembles a simple electrical circuit using spring contacts as the core components and other necessary structures.For the spring contact prototype

both heat generation and transfer are taken into consideration. Based on the above analysis

the temperature rise in steady state of the spring contact prototype was simulated at 4 current levels of each AC and DC groups. By comparing the simulation and experimental results

the research method was verified

which provides certain reference for further design of high-voltage electrical apparatus and other complex temperature field simulation.
