【摘要】：空氣間隙火花放電路徑具有曲折、分支的半隨機(jī)發(fā)展特點(diǎn)。空間光電離過(guò)程光子數(shù)量和位置的隨機(jī)性是導(dǎo)致空氣間隙操作沖擊火花放電路徑具有隨機(jī)性的主要原因,空間電荷和電場(chǎng)對(duì)放電路徑的發(fā)展具有一定的約束。該文采用250/2500μs負(fù)極性操作沖擊電壓波分別開(kāi)展了間隙距離為0.4~1.2m的三種不同空氣間隙的放電試驗(yàn),對(duì)比分析了間隙距離、負(fù)極性操作沖擊電壓幅值對(duì)火花放電路徑初始方向角概率分布的影響。結(jié)果表明:棒 棒間隙、棒 雙棒間隙火花放電路徑初始方向角具有統(tǒng)計(jì)特性,且服從正態(tài)分布,該分布特性受間隙距離、棒電極形狀及外施負(fù)極性沖擊電壓幅值影響。該研究結(jié)果可以加深對(duì)空氣間隙火花放電過(guò)程的理論認(rèn)識(shí)。
[Abstract]:The air gap spark discharge path is characterized by twists and turns. The randomness of photon number and position in the spatial photoionization process is the main reason for the randomness of the air gap operation impact spark discharge path. Space charge and electric field have some constraints on the development of discharge path. In this paper, three kinds of air gap discharge experiments with gap distance of 0.4 ~ 1.2m are carried out using 250/2500 渭 s negative operating impulse voltage wave, and the gap distance is compared and analyzed. The effect of the amplitude of the negative operating impulse voltage on the probability distribution of the initial direction angle of the spark discharge path. The results show that the initial direction angle of the spark discharge path has statistical characteristics, and the initial direction angle of the spark discharge path is normal distribution. The distribution characteristics are affected by the gap distance, the shape of the rod electrode and the amplitude of the applied negative impulse voltage. The results of this study can deepen the theoretical understanding of the spark discharge process in the air gap.
