Laser trigger vacuum switch and switch system

Abstract

The invention discloses a laser trigger vacuum switch and a trigger system apparatus thereof. The laser trigger vacuum switch comprises a closed housing, a first electrode main member and a second electrode main member. The first electrode main member comprises an arcing electrode, a first electrode flange, a first electrode platform and a focusing mirror. The second electrode main member comprises an arcing electrode, a second electrode flange, a second electrode platform and a target electrode. The trigger system apparatus mainly comprises a computer, a converter, a switch circuit board, a laser and the laser trigger vacuum switch. The laser trigger vacuum switch has a working voltage as high as 30 kV and a working current as high as 500 kA. The problems of difficult trigger high voltage isolation, trigger stability, short service life and the like by use of electric pulses in the prior art are solved, the laser trigger energy can be effectively reduced, and the time delay and jittering of a switch device are improved. The laser of the trigger system apparatus realizes miniaturization completely, a matched laser system is greatly simplified, and a special power supply device, a special water cooling machine and a special laser collimation system are unnecessary.

Description

Technical field [0001] The invention belongs to the technical field of high-voltage and high-current pulse switches, and more specifically, relates to a laser-triggered vacuum switch and switch system. Background technique [0002] Pulsed power technology is an electrophysical technology that stores electric (magnetic field) energy with lower power (voltage, current), converts it into pulsed electromagnetic energy with much higher power, and releases it to a specific load. The product of the combination of second pulse electronics, general high voltage technology and applied physics. With its rapid development and application in national defense and civilian high-tech, high-voltage and high-current pulse switches have become one of the key devices restricting the development of modern pulse power technology. Electric energy-driven weapons such as electromagnetic railguns require that the huge energy in the energy storage element be released to the load through a switch in a very...
