A planar trigger type low jitter long life gas spark gap switch

Abstract

The invention discloses a plane triggered gas spark gap switch with low jitter and a long service life, and belongs to the technical field of pulse power. The gas spark gap switch comprises a trigger disk, two insulating cover plates, two discharge electrodes and two conductive electrodes, one insulating cover plate is separately arranged on both sides of the trigger disk, one discharge electrode and one conductive electrode are respectively arranged on both sides of each insulating cover plate, and each insulating cover plate and the trigger disk are fastened into an entirety by bolts. According to the gas spark gap switch disclosed by the invention, the trigger disk is designed into a cylinder with two concave bottom surfaces, the outside diameter of the cylindrical trigger disk is slightly smaller than the diameter of the whole gas spark gap switch, the height of the trigger disk directly determines the distance between the discharge electrodes, and the switch performance consistency is good. The design of the planar trigger electrode and the bowl-shaped discharge electrodes is conducive to the uniform distribution of an electric field of the gas spark gap switch, and the design of the periodically convex insulating cover plates is conducive to the uniform distribution of the gas flow of an insulating gas, therefore the stability of the switch is effectively improved, and the output jitter is reduced.

Description

technical field [0001] The invention relates to the technical field of pulse power, in particular to a repetition rate gas spark gap switch with low output jitter and high stability. Background technique [0002] Pulse power technology achieves instantaneous high power output by slowly storing initial energy for a long period of time and then releasing it quickly in a short period of time. Due to its high power and short pulse characteristics, pulse power technology can produce some special effects. It is currently widely used in nuclear explosion simulation, environmental protection, food processing, high-power laser / microwave and other fields. [0003] The pulse power system is the main means of obtaining pulse power, and its core is energy storage devices and switching devices. The main function of the pulse power circuit is pulse compression and pulse shaping, that is, through the control of the switch, the required energy is released within a specified time. Therefore...

Problems solved by technology

The electrode ablation phenomenon of this trigger electrode design is serious, and the service life is short, and a small change in the spatial position of the trigger discharge end will cause a significant change in the switch performance, resulting in poor switch consistency, and it is difficult to achieve long-term continuous and stable operation.
