Embodiment Construction

[0026] As shown in Figure 3, the multi-channel laser-triggered vacuum surface flashover switch of the present invention includes two parts: discharge work and trigger. The discharge work part is mainly composed of positive and negative electrodes 1, surface insulation medium 2, and insulation shell 4. Integrated together, there is no special insulating case4. The trigger part is composed of laser 7, laser transmission system 9, focusing system 10 and control system. The electrode 1 is tightly pressed on the surface of the insulating medium 2. On the basis of not destroying the mechanical and electrical properties of the insulating medium 2, it should be in close contact with the insulating medium 2 as much as possible. into the running line. The insulating casing 4 surrounds the electrode 1 and the insulating medium 2 of the switch in a vacuum environment. Electrode 1 stretches out from the both sides of insulating shell 4, and two ports will be sealed, and insulating shell ...

Abstract

This invention relates to one multi-channel laser trigger vacuum section flash switch, which is characterized by adding high voltage between anode and cathode, wherein, the fix impulse laser with wavelength of 532nm sends out laser beam to focus onto level anode and cathode two ends parallel laser line or one band onto insulation medium surface; the insulation medium surface laser energy intensity for 1-5mJ / mm2 to lead insulation medium surface flash to connect circuit.

Description

technical field [0001] The invention relates to a multi-channel laser trigger surface flashover switch, which is especially suitable as a fast and accurate trigger closing switch in pulse power technology. Background technique [0002] Rapid closing switch is one of the important technologies in pulse power technology, and it is also a difficult problem and an urgent problem that restricts the development of pulse power technology. Laser-triggered surface flashover switch is a switch form that can meet high-speed and high-power requirements. It is an important way to solve the rapid energy transmission and conversion in pulse power equipment. Its research and development are for the realization of new high-power narrow pulse generators, High-power microwave and dielectric wall accelerators provide important theoretical basis and technical support. [0003] There are many forms of closure switches, each with its own characteristics and scope of application. Compared with gas...
