A Press-fit Structure of Modular Pulse Thyristor

Abstract

The invention discloses a press-fitting structure of a modular pulse thyristor, comprising an upper press-fitting disc, a lower press-fitting disc, an upper lead-out wire disc, a lower lead-out wire disc, a press-fit bolt, a buffer element, an insulating rod, a protection circuit module, Trigger circuit module, cable terminal access screw holes and outer protective cover; buffers are installed between the upper press mounting plate and the upper lead-out cable plate, and between the lower pressure-mount plate and the lower lead-out cable plate element. A series of single thyristor thyristor switches connected in series and in parallel are pressed between the upper and lower pressing plates. The pressing force is realized by the tension of several rod-shaped insulating rods between the upper and lower pressing plates. There are studs or internal threaded holes for fixing rod-shaped insulating pull rods on the upper and lower press-fitting discs, and the studs or internal threaded holes are evenly distributed on the press-fitting discs in a symmetrical layout.

Description

technical field [0001] The present invention belongs to the field of high-voltage electrical appliance technology and pulse power technology, and more specifically relates to a press-fit structure of a modular pulse thyristor. Background technique [0002] Pulse power technology refers to the electrophysical technology that stores high-density energy for a long time, performs rapid compression, conversion, or directly releases energy to the load in a short time. Switching devices occupy a special place in pulsed power systems, and any progress in the ability to transfer stored energy to loads is premised on the successful design and development of a variety of pulsed high-current switches. [0003] In the application occasions of capacitive energy storage pulse power technology such as strong laser devices, strong magnetic field devices, and high-power microwaves, the requirements for switches are mainly to withstand high voltage, high current, short breakdown time delay and...

Problems solved by technology

[0006] Aiming at the defects of the prior art, the purpose of the present invention is to provide a press-fit structure of the modularized pulse thyristor, aiming at solving the problem of using the switch high and low voltage extremely unilateral centralized lead wire layout in the prior art, because the lead wires The ends are concentrated on one side, resulting in unbalanced force and torque at each point of the switch when the electric stress shock comes, which is likely to cause damage to the switch structure and fatigue damage.
