摘要

高压直流断路器吸能装置中氧化锌阀片的并联柱数愈多、每柱中串联的氧化锌阀片的片数愈少

则电流不均衡分布的问题愈严重.计算表明

只要合理地进行搭配吸能装置各柱中的氧化锌阀片

电流的不均衡性可以减少到很低的水平.

Abstract

The current distribution between parallel ZnO varistor columns of energy absorber in HVDCCB is discussed in this paper. The inequable current dis-tribution will increase in direct ratio with the number of the parallel ZnO varistor columns and in inverse ration with the number of series ZnO varistors. Calculation results show that the reasonable selection of the ZnO varistor in each column will reduce the inequable current distribution between parallel varistor columns to a lower level.
