摘要

为了研究动静触头槽口装配位置对真空灭弧室性能的影响

文中采用仿真计算和试验相结合的方法

对不同动静触头槽口装配位置的真空灭弧室性能进行了分析

得出了装配位置对磁感应强度和电弧形态的影响规律。当动静触头槽口错位45°装配时最大磁感应强度分别为63.71、64.31、64.18 mT

电弧尺寸比较小

电弧的运动比较稳定

电弧电压为36 V

开断性能更好。动静触头槽口错位45°装配有利于提高真空灭弧室开断性能。

Abstract

To understand the effect of rabbet assembly position of moving and static contacts on performance of vacuum interrupter

simulation and experimental methods were employed to analyze the performance of a vacuum interrupter with different rabbet assembly position

and the effects of rabbet assembly position on magnetic flux density and arc pattern were obtained. The results showed that when the dislocation degree of rabbet was 45°

the maximum value of magnetic flux density was 63.71

64.31 and 64.18 mT

respectively; the arc had smaller size

more stable movement

and the voltage of 36 V; and the interruption performance of the vacuum interrupter was better. So it is concluded that the interruption performance of the vacuum interrupter can be improved at 45° dislocation of rabbet in assembly.
