Abstract

The invention relates to the research field of gas discharge and gas insulation performance, especially a vacuum experimental device for measuring gas Thomson discharge parameters. The technical problem solved by the invention is to meet the measurement requirements of Thomson discharge parameters. The technical scheme of the invention Including the photoelectric double-channel high-voltage sealing sleeve passing through the upper cover of the discharge chamber to connect with the discharge gap, the Rogowski upper electrode is installed with an entrance for exciting electrons, the optical lens is designed to be replaceable, and the vacuum baffle valve connects the discharge chamber to the discharge chamber. It is connected with the vacuum system, and the sealed transmission package is installed on both sides of the lower cover of the discharge chamber. The discharge gap is connected with the vacuum electrode through the lower electrode connection line. The regulator inflates the discharge chamber through the sample gas channel. The vacuum discharge chamber is equipped with an extended observation window, a main observation window, and an extended connection port. The contact surfaces of each opening are sealed with fluorine rubber O-rings.

Description

technical field [0001] The invention relates to the research field of gas discharge mechanism and gas insulation performance, in particular to a vacuum experimental device for measuring gas Thomson discharge parameters. Background technique [0002] The Thomson discharge parameter of gas can be used to characterize the ability of gas to inhibit the development of discharge and the insulation performance, and can also be used to study the development mechanism of gas discharge. This parameter is very important in the fields of plasma physics and gas insulation. The main content of this experiment is to measure the discharge current of gas under different pressure, spacing and electric field strength. During the experiment, the amount of sample used is small, the working air pressure is low, and there is reciprocating mechanical movement, but the traditional dynamic seal can hardly meet the experimental requirements, which brings greater difficulty to the sealing design of the...
