A Pneumatic Series High Voltage Switch

Abstract

The invention discloses a pneumatic series high voltage switch comprising multiple levels of switches, wherein each level of switch comprises a low voltage electrode, a high voltage electrode and a trigger electrode, the low voltage electrodes and the high voltage electrodes of all switches are of an annular hollow structure, an insulating rod is arranged in the annular hollow structure, a plurality of the trigger electrodes are arranged on the insulating rod, each trigger electrode corresponds to a switch, and the insulating rod is driven by a cylinder piston to move along the axial direction of the annular hollow structure. The pneumatic series high voltage switch disclosed by the invention adopts an overall coaxial linear structure, therefore the inductance of the structure is small, the high voltage switch is triggered by mechanical movement, so that the reliability is very high, complete electrical isolation of a trigger control system and a main discharge loop is realized, the trigger control system is greatly simplified, a high voltage pulse system and a laser system, which are expensive and fragile, are omitted, thereby greatly reducing the cost and improving the environmental adaptability, and the pneumatic series high voltage switch is suitable for triggering military and compact MARX generators.

Description

technical field [0001] The invention relates to the field of high voltage, in particular to a device capable of using compressed gas to drive multi-stage high voltage switches to be disconnected or turned on synchronously in series, which is applied to the trigger of a MARX generator. Background technique [0002] The MARX generator is widely used in high-voltage technology and lightning simulation. Its basic working principle is that multi-stage capacitors are charged in parallel and discharged in series to increase the charging voltage. In order to achieve the purpose of series discharge, the MARX generator trigger switch is required to be turned on synchronously, so as to realize the superposition of voltage. [0003] In "Pulse Power Science and Technology" and other books, there are introductions to the principle and circuit of the classic MARX generator, but there is no description of the specific design method of the trigger switch. The current known triggering method...
