Abstract

The invention provides a gas spark gap switch for a nanosecond pulse generator. The gas spark gap switch comprises a coaxial cable, a high-voltage spark discharge electrode, a grounding spark discharge electrode and an electronic gas pressure controller, wherein the coaxial cable is arranged on one side of a gas cavity, the high-voltage spark discharge electrode and the grounding spark discharge electrode are arranged in the gas cavity, the high-voltage spark discharge electrode is connected with the coaxial cable, the grounding spark discharge electrode is connected with a ground electrode, and the electronic gas pressure controller is used for controlling spark discharge and extinguishing of the high-voltage spark discharge electrode and the grounding spark discharge electrode by controlling gas pressure in the gas cavity. The switch is integrally of a coaxial structure and has characteristic impedance matched with a pulse forming network, electrode spacing is adjustable, the switch is low in coupling capacitance, spark inductance and spark resistance, high in repetition frequency and wide in adjustable puncture voltage range, generated nanosecond pulse rising edge is rapid, the shape of nanosecond pulse is close to ideal rectangular pulse, and spark discharge is controlled by the gas pressure controller.

Description

technical field [0001] The invention relates to the field of manufacturing a high-voltage gas spark gap switch, in particular to a gas spark gap switch used for a nanosecond pulse generator. Background technique [0002] The gas spark gap switch is the core component of the pulse power device. Its application environment and field mainly change according to the use of the generator, and it plays a vital role in the fields of industrial dust removal, water purification, and medicine. Its performance directly affects the performance index of the pulse generator output pulse. At present, there are three main ways to trigger the gas spark gap switch of the nanosecond pulse generator. One is to apply a fast-front voltage pulse on the trigger electrode to generate a higher overvoltage multiple in the trigger gap, and the other is to use ultraviolet radiation. , and another is to use laser irradiation. [0003] Under the premise of considering the cost and comprehensive performan...
