Switch and capacitor integrated fast frontier nuclear electromagnetic pulse source

Abstract

The invention relates to a switch and capacitor integrated fast frontier nuclear electromagnetic pulse source of which the output can be continuously adjusted. The switch and capacitor integrated fast frontier nuclear electromagnetic pulse source is characterized in that a switch earth electrode is an outer cylinder with a coaxial structure; a switch motion trigger electrode and a low-inductance energy-storage capacitor sequentially form an inner core with coaxial structures from outside to inside; a switch gap is reserved between the switch motion trigger electrode and the low-inductance energy-storage capacitor; the low-inductance energy-storage capacitor comprises the structure that a plurality of film dielectric capacitance components are arranged between a high-voltage electrode and a low-voltage electrode and connected in series; and one end of the high-voltage electrode is arranged on one side of the switch gap and connected with a charging cable through a through hole on one side of the ground electrode. The switch and capacitor integrated fast frontier nuclear electromagnetic pulse source has compact circuit and low inductance, greatly reduces the frontier of output pulse, avoids the structure of a Matrix generator with multiple switches and multiple energy-storage capacitors and reduces the complexity of the system. Meanwhile, the output pulse frontier meets the IEC (International Electrical Committee) 6100-2-9 standard without using a peaking capacitor and a peaking switch; and the pulse source can continuously adjust the output voltage.

Description

technical field [0001] The invention relates to a fast-frontier high-voltage pulse generator, in particular to a fast-frontier nuclear electromagnetic pulse source with integrated output of a switch and a capacitor that can be continuously adjusted. Background technique [0002] Since the 1960s, nuclear electromagnetic pulse (NEMP) and its engineering protection technology have attracted widespread attention from all countries, and many electromagnetic pulse simulators have been built in the world. The NEMP simulators built in the early stage, such as the ARES, Trestle, and NEMPS simulators in the United States, the IEMP26 simulator in Russia, and the EMIS II simulator in the Netherlands, etc., generally have a leading edge of about 8-10ns and a pulse duration of 200-500ns. With the in-depth understanding of NEMP and the gradual revision of standards, the current research hotspots are simulating a new fast-frontier EMP environment and developing a fast-frontier electromagnet...

Problems solved by technology

It can be seen from the schematic diagram that the Marx generator-type fast leading-edge high-voltage pulse source includes multi-stage energy storage capacitors and gas switches, and also includes a large number of charging / isolation resistors, grounding resistors, and trigger resistors. Therefore, the pulse source has a complex structure, large volume, and high cost. , and limited by the series establishment of the Marx generator, the output voltage cannot be continuously adjusted
