Abstract

In order to make the vacuum circuit breaker used in high-voltage level, it is necessary to study the high voltage vacuum interrupter. This paper presented an axial magnetic field three quarters of the coil structure for high voltage level. Its axial magnetic field characteristics were calculated and analyzed with the Maxwell Ansoft software, The magnetic field produced by the structure is uniform, the maximum magnetic field value is 9.4mT, the minimum magnetic field value is 4.08mT, the uniform area of the maximum magnetic field is 0.25 dm2, 40% of the total area occupied by, and the residual magnetic field is small. The value is 2.8mT. The influence of the magnetic field strength and uniformity for the different slot positions of the contact was analyzed. The results showed that the slot position is in the right of the contact; the maximum magnetic field value is larger and more uniform. It also can enhance the arc control of the contact, promote arc converting to diffuse arc, improve the breaking capacity.

一种新型高压真空灭流器轴向磁场接触四分之三线圈及其性能

为了使真空断路器应用于高压水平，有必要对高压真空断路器进行研究。本文提出了一种轴向磁场四分之三的线圈结构，适用于高压电平。利用Maxwell Ansoft软件对其轴向磁场特性进行了计算和分析，该结构产生的磁场均匀，最大磁场值为9.4mT，最小磁场值为4.08mT，最大磁场的均匀面积为0.25 dm2，占总面积的40%，剩余磁场较小。其值为2.8mT。分析了接触面不同槽位对磁场强度和均匀性的影响。结果表明:槽位位于触点右侧;最大磁场值更大，更均匀。还能增强触点的电弧控制，促进电弧向扩散电弧转化，提高分断能力。
