Abstract

Air gap discharge is one of the most basic scientific problems in the field of high-voltage engineering. The homogeneous electric field 1.5 mm air gap negative streamer at overvoltage and atmospheric pressure is observed by a high-speed 4-channel framing camera. The ultra-high temporal resolution images of a single negative stream are captured (the exposure time is 5 ns, and the inter-frame delay is no more than 0.1 ns). It is observed that the negative streamer formed in the middle of the air gap and grew bidirectionally towards both electrodes. At the same time, the electrical measurement is also carried out.

过电压和大气压下均匀电场短气隙负流束的超高时间分辨率图像

气隙放电是高压工程领域最基本的科学问题之一。过电压和大气压力下的 1.5 毫米气隙负流均匀电场由高速 4 通道取景相机观测。拍摄到了单个负流的超高时间分辨率图像（曝光时间为 5 毫微秒，帧间延迟不超过 0.1 毫微秒）。可以观察到负极流在气隙中间形成，并向两个电极双向生长。与此同时，还进行了电学测量。
