A three-electrode field-distorted gas spark switch

Abstract

The invention provides a gas spark switch with three-electrode field distortion, which solves the problem of relatively poor service life and stability of the existing gas switch. The gas spark switch includes an insulating shell, an upper electrode, a lower electrode, an electrode connector, a trigger electrode, an electrode positioning block, a trigger connector, a left cover, a right cover and a gas nozzle; the insulating shell is a rectangular shell, including an upper Side plate, lower side plate, front side plate and rear side plate; the upper electrode and the lower electrode are set inside the insulating shell, and the electrode connectors are set in the mounting holes of the upper side plate and the lower side plate; the electrode positioning block is set in the insulating shell The left and right sides of the inner cavity; the trigger electrode includes a wedge-shaped disc and a long support plate, the wedge-shaped disc is located between the upper electrode and the lower electrode, and a central through hole is set in the center; the left end of the trigger connector is set outside the left cover plate , the right end is electrically connected to the trigger electrode; the gas nozzle is set in the gas nozzle installation hole, the gas spark switch has a compact structure, low inductance, and the trigger performance meets the needs of FMG research and development.

Description

technical field [0001] The invention belongs to the field of gas switches, in particular to a three-electrode field distortion gas spark switch, which is suitable for fast Marx generators. Background technique [0002] High-power gas switches are widely used in primary pulse sources. Because of their high operating voltage, strong flow capacity, and large amount of charge transfer, they are key devices for generating initial electric pulses. And waveform control plays a decisive role. [0003] The Marx generator is a common primary pulse source and is widely used in large pulse power devices. The traditional Marx gas switch mainly uses a long cylindrical shape as the overall outline of the switch, such as the Marx gas switch of the "Flash No. 2" accelerator. The electrode height and insulation gap distance of this gas switch are relatively long, so the structural inductance of the switch is relatively large ;In the newly developed fast discharge primary pulse source techno...
