Air-tightness gap-adjustable type spark-gap switch operation method

Abstract

The present invention discloses an air-tightness gap-adjustable type spark-gap switch operation method and provides an air-tightness gap-adjustable type spark-gap switch. The switch is in the form of a spark-gap controllable switch and comprises an anode, a cathode and a trigger electrode. An air-tightness switch working space is formed by an insulated housing, an anode flange, a cathode flange, a trigger electrode insulated sheath, an anode sealing pressure plate, a trigger electrode sealing pressure plate and a sealing washer at a corresponding seam. An inflation and exhaust system is formed by an inflation valve and an exhaust valve. After that, an anode lead and a cathode lead are connected as required. Then the operation of the air-tightness gap-adjustable type spark-gap switch is enabled. The method meets the requirements of applications and changes the operating pressure of the switch and the air atmosphere of the switch. Meanwhile, the operation reliability of the switch is improved and the anti-interference capability of the switch is enhanced. Moreover, through changing the discharge distance between the cathode and the anode, the requirements of different operating voltage levels in different applications can be met. In addition, the service life of the spark-gap switch is prolonged and the environment adaptability of the switch is improved.

Description

technical field [0001] The invention belongs to the technical fields of pulse power technology, high-energy laser and high-energy pulse current experimental research, and particularly relates to an operating method of a spark gap switch with adjustable airtight gap. Background technique [0002] Pulse power technology is a technology that compresses energy in time and space, and then releases energy to specific loads with higher power in a shorter period of time. The pulse power supply is the key device in the pulse power system. Its function is to generate high instantaneous power pulses in a short period of time to drive specific loads. It generally consists of three parts: energy storage devices, high-voltage switches and loads. Among them, the high-voltage switch is a key component for forming high-voltage pulses, and it is also the core of the high-voltage pulse power supply. The performance of the high-voltage switch directly determines the overall performance of the p...

Problems solved by technology

Although traditional switches such as thyristors, IGBTs, and MOSFTs have long working life and high repetition frequency, the breaking voltage and current should not be too large, the breaking power is small, and it takes a long time to break high voltage and high current, which is expensive and requires Complex control and protection circuits, thus limiting its application in high-voltage pulse power supply technology
