Abstract

The invention discloses a two-electrode pneumatic high-voltage pulse switch. The pulse switch comprises an insulating shell, an air cylinder, a moving electrode, a fixed electrode, an insulating fluidmedium and a pneumatic system. The switch is characterized in that: the moving electrode is arranged on a moving rod of the air cylinder; the air cylinder and the fixed electrode are arranged on theinsulating shell; the insulating fluid medium is compressed gas or insulating oil; and the pneumatic system controls the air cylinder to drive the moving electrode to touch the fixed electrode, and the switch is conducted for discharging. The pulse switch provided by the invention has the advantages of simple structure, high speed, high voltage resistance and strong anti-interference capability.

Description

technical field [0001] The invention relates to a two-electrode pneumatic high-voltage pulse switch, in particular to a high-speed high-voltage two-electrode pneumatic switch used in a high-voltage pulse source of an electromagnetic pulse simulator. Background technique [0002] With the development of informatization, various electronic information devices are widely used, and electromagnetic pulse poses a huge threat to electronic information devices. In order to study the effect and protective effect of various electromagnetic pulses on electronic equipment, various pulse sources need to be developed, and switches with high voltage resistance and fast switching speed are required in the pulse source. The current switch has a gas switch and an oil switch. The gas switch is usually a two-electrode switch, and the gap between the two-electrode switches is filled with a certain pressure of gas, such as air, nitrogen, SF 6 Wait, when the pressure gas is released, the switch...
