組合空氣間隙放電路徑選擇性試驗
[Abstract]:In order to study the dispersion and randomness of the development of air gap discharge path, the characteristics of the gap between the rod and the rod, the breakdown characteristics of the combined gap, the characteristics of the discharge path selection and the random characteristics of the development of the discharge path are studied respectively. The influence of the shape of the lower rod electrode head and the arrangement of the lower rod electrode is considered in the experiment. The influence of the gap electric field nonuniformity coefficient on the discharge voltage of 50% is analyzed by electrostatic field simulation. The influence of the electrostatic field intensity around the electrode head on the characteristics of discharge path selection is also discussed, and the initial developing angle 胃 of electrode surface is calculated by image processing technique to characterize the random characteristics of discharge development on the surface of high voltage rod electrode. The experimental and simulation results show that the larger the gap electric field nonuniformity coefficient is, the lower the gap 50% discharge voltage is when the gap distance is 0.4 ~ 1.2 m. When the gap distance is the same, the bigger the curvature of the head of the lower rod electrode, the greater the field strength around the head, and the more likely it is to produce headstream, the higher the probability of being hit, the more the gap distance has an effect on the selectivity of discharge path. The smaller the gap distance is, the greater the electric field intensity around the head of the rod electrode is, and the higher the upward flow is, the higher the probability of being hit is. The increase of air gap distance will reduce the binding force of the lower rod electrode on the initial development direction of the high voltage rod electrode discharge, and the development direction of the downward flow on the head surface of the high voltage rod electrode will be enhanced.
