Embodiment Construction

[0039] The invention relates to a gas switch with a four-electrode structure, which includes two high-voltage electrodes and two trigger electrodes, and is triggered by pulses of positive and negative polarities. At the moment of triggering, the voltage polarity on the high-voltage electrode and the trigger electrode alternates in the order of positive, negative, positive, and negative.

[0040] figure 1 It is a longitudinal sectional structure diagram of the present invention. The four-electrode switch has a maximum working voltage of ±100kV and is triggered by a pulse of ±70kV. The distance between the high-voltage electrode and the trigger electrode, and between the trigger electrode and the trigger electrode is 6mm. The working medium can be sulfur hexafluoride gas, nitrogen gas or a mixture of the two.

[0041] When triggering at the same time, the working process of the present invention is as follows: (1) the switch is in an off state, and the high-voltage electrodes ...

Abstract

The invention relates to a four-electrode bipolar pulse triggering gas switch which comprises an insulation outer barrel, a positive polarity high-voltage electrode, a negative polarity high-voltage electrode, triggering electrodes and working media, wherein the positive polarity high-voltage electrode and the negative polarity high-voltage electrode are arranged at the two ends of the insulation outer barrel respectively, the triggering electrodes are arranged between the positive polarity high-voltage electrode and the negative polarity high-voltage electrode, and the working media are arranged in the insulation outer barrel. The positive polarity high-voltage electrode and the negative polarity high-voltage electrode are connected with positive polarity direct-current high-voltages and negative polarity direct-current high-voltages respectively, the triggering electrodes comprise a negative polarity triggering electrode and a positive polarity triggering electrode, the positive polarity triggering electrode and the negative polarity triggering electrode are connected with positive polarity pulses and negative polarity pulses respectively, the negative polarity triggering electrode is adjacent to the positive polarity high-voltage electrode, and the positive polarity triggering electrode is adjacent to the negative polarity high-voltage electrode. The four-electrode bipolar pulse triggering gas switch solves the technical problems that an existing gas switch has high requirements for pulse triggering amplitude and is low in the overvoltage coefficient in the switch self-breakdown process.

Description

technical field [0001] The invention relates to a four-electrode bipolar pulse trigger gas switch, which is mainly characterized in that positive and negative polarities are used for charging, and positive and negative polarity pulses are alternately used for triggering, which can realize low trigger threshold and low jitter. Background technique [0002] Switches play an important role in pulsed power devices, and their performance directly affects the output characteristics of the device. The gas switch is the most widely used due to its high working voltage, strong flow capacity, fast conduction speed, small resistance and inductance after conduction, and can be reused. However, gas switches have a higher trigger threshold compared to solid state switches. [0003] Most of the existing gas switches are triggered by a single unipolar pulse, which requires a high amplitude and a steep leading edge of the trigger pulse. [0004] Take the ±100kV three-electrode field-distor...
