Electromagnetic gun arc extinguishing device based on RSD

Abstract

The invention discloses an electromagnetic gun arc extinguishing device based on RSD, and belongs to the field of electromagnetic emission. The electromagnetic gun arc extinguishing device based on RSD is connected with an armature on an electromagnetic railgun device in parallel, a trigger switch driving module and a reset circuit driving module respectively drive an RSD trigger circuit and a magnetic switch reset circuit to work when receiving control signals; when the RSD trigger circuit works, the RSD is triggered to be switched on; the magnetic switch reset circuit is used for helping themagnetic switch to realize magnetic reset before working; when the RSD is triggered, the magnetic switch isolates the RSD from external voltage to prevent the RSD from being damaged; and controllingthe turn-on of the RSD can control current transfer across the armature. According to the electromagnetic gun arc extinguishing device based on the RSD, a RSD switching device belongs to a semiconductor device, and has the advantages of stable work, strong current endurance capability, capability of bearing a current peak value up to hundreds of kA, capability of bearing bearable current rising rate which is hundreds of kA/mu s and low conduction impedance, so that the electromagnetic gun arc extinguishing devic has the advantages of long service life, high current transfer speed and the like.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic emission, and more particularly relates to an arc suppressing device for an electromagnetic gun based on an RSD (reversely switched transistor). Background technique [0002] Electromagnetic launch technology uses electromagnetic energy to propel objects to high-speed or ultra-high speed. It is a revolution in launch methods after mechanical energy launch and chemical energy launch. It transforms electromagnetic energy into instantaneous kinetic energy required for launch, which can be realized within a short distance. Accelerating loads ranging from grams to tens of tons to high speeds and breaking through the speed and energy limits of traditional launch methods is an inevitable choice for future launch methods. The electromagnetic launching device is mainly composed of electromagnetic rail gun, electromagnetic coil gun, electromagnetic reconnection gun and so on. Among them, the electr...
