摘要

摘要: 为降低气体放电间隙直流条件下自击穿电压分散性，尽可能不影响其自击穿电压，基于环形电极放电间隙，设计了一种在阴极中心植入辅助放电针的辅助放电电极结构。通过电场仿真，研究了辅助放电针直径、长度和顶部倒角对放电间隙场畸变的影响。实验研究了放电间隙无辅助放电针和植入辅助放电针后，其在干燥空气和SF₆气体中的直流自击穿特性。结果表明：辅助放电针直径越小、长度越长，电极环对其电场屏蔽作用越弱，放电间隙场畸变强度越大；辅助放电针对SF₆气体放电间隙直流自击穿电压值影响较小，随着场畸变系数的增大，同一气压下干燥空气自击穿电压下降百分数为SF₆气体的2～3倍；辅助放电针对直流条件下干燥空气和SF₆气体放电间隙自击穿稳定性具有有益作用，分散性减小百分数较无辅助放电针结构均提高约25%。

Abstract: In order to reduce the jitter of the direct current self-breakdown voltage, not affect the self-breakdown voltage as much as possible, an auxiliary discharge electrode structure with an auxiliary discharge needle implanted in the cathode center is designed based on the discharge gap of the annular electrode. The influence of the diameter, length and top chamfer of the auxiliary discharge needle on the field distortion is studied by electric field simulation. The direct current self-breakdown characteristics of the unintroduced auxiliary discharge needle and the introduce auxiliary discharge needle in dry air and SF₆ gas are studied by experiments. The results show that the smaller the diameter and the longer the length of the auxiliary discharge needle, the weaker the shielding effect of the electrode ring on the electric field, the stronger the field distortion intensity;the influence of the implatation of auxiliary discharge needle on the direct current self-breakdown of SF₆ gas discharge gap is small,and with the increase of the field distortion coefficient, the percentage drop of self-breakdown voltage of dry air at the same air pressure is 2～3 times that of SF6 gas; the auxiliary discharge needle has a beneficial effect on the breakdown stability of dry air and SF6 gas discharge gap under the condition of direct current , the dispersion reduction percentage is about 25% higher than that without auxiliary discharge needle.
