Abstract

The invention discloses a switch and capacitor integrated quick discharge unit. Two capacitors and a switch arranged between the two capacitors form a coaxial structure; a high-voltage electrode (2; 12) is led from a capacitor and is simultaneously used as the high-voltage electrode of a gas switch; and the capacitors and the switch commonly share one insulating shell. By adopting the discharge unit, under the same energy storage condition, the module dimension and the branch inductance can be reduced obviously; the output current can be improved; the boosting time can be reduced; the discharge current peak can be improved, the pulse current front can be shortened, and the switch and capacitor integrated quick discharge unit has wide application in pulse power primary energy storage Marx generators and linear pulse transformer driving sources.

Description

technical field [0001] The invention relates to a fast discharge technology integrating a switch and a capacitor, in particular to a fast discharge unit integrating a switch and a capacitor. It is widely used in pulse power primary energy storage Marx generators and linear pulse transformer drive sources. Background technique [0002] Pulse power technology has extremely important applications in national defense and civilian fields such as nuclear weapon physics, high energy density physics, radiation effect simulation, inertial confinement fusion (ICF) and fusion energy (IFE), and the pulse power drive source is the basis and premise of the application. At present, the world is actively studying the construction of the next generation of large-scale pulse power sources based on the linear pulse transformer (LTD). The most basic unit "branch" in LTD consists of two capacitors with a working voltage of 100kV and a capacity of tens of nF connected in series with a gas switch...
