摘　　要：由于杂散电容的影响,多断口真空断路器的电压分布是不均匀的,但是目前尚无针对多断口真空断路器的均压电容选择方法。笔者对多断口真空断路器均压电容的研究现状进行了综述,总结了均压电容对提高多断口真空断路器开断能力的积极作用和可能带来的负面效应,并对积极作用以及负面效应的产生机理进行了分析。指出了现有研究的局限性,并进行了初步的分析。在此基础上,提出了多断口真空断路器均压电容的研究建议,可为多断口真空断路器均压电容的深入研究提供参考。The voltage applied to each vacuum interrupter of a multi-break vacuum circuit breaker is not equal one another because of stray capacitances.But the selection standard of grading capacitors for multi-break vacuum circuit breakers has not yet been published now.In this paper,the present research on grading capacitors for multi-break vacuum circuit breakers was overviewed.The positive role and negative effect of grading capacitors for the improvement of breaking capability of multi-break vacuum circuit breakers were summarized,and the mechanism of the positive and negative effect was analyzed.The limitation of available research results was also pointed out,and a preliminary analysis was given.Based on the analysis,several suggestions are proposed,which can provide reference for the further study of grading capacitors.
