Problems solved by technology

In the injection plasma triggering technology, during the plasma injection process, the interior of the cavity is punctured due to air along the surface, which generates a large current discharge, which obviously causes serious ablation inside the injection device and greatly reduces the service life, thus affecting the stability of the device. Significant impact on performance and reliability

Abstract

Disclosed are a rotary plasma jet trigger device and a trigger method. In the rotary plasma jet trigger device, multiple front-stage trigger devices generate trigger pulses for alternately breaking down and conducting air gap switches; the negative polarity high-voltage DC source is charged through a protective resistor After the energy storage capacitor and the air gap switch break down and conduct based on the trigger pulse, the energy storage capacitor discharges the discharge resistor through the circuit to generate a high-voltage pulse; the needle electrode arranged in the through hole is connected to the trigger circuit to receive the high-voltage pulse, and the needle electrode The electrode, the plate electrode with the excitation chamber and the high-voltage electrode constitute the plasma injection device. When the high-voltage pulse received by the needle electrode is applied to the excitation chamber, the excitation chamber ejects plasma into the gas switch in turn to discharge to guide the gas switch. breakdown conduction.

Description

technical field [0001] The invention relates to the technical field of high-voltage electric engineering, in particular to a triggering device and a triggering method for a rotary plasma jet. Background technique [0002] Due to its low jitter and low operating coefficient, the plasma jet trigger device has a good application prospect in the field of fast discharge of high-voltage switches. In the injection plasma triggering technology, during the plasma injection process, the interior of the cavity is punctured due to air along the surface, which generates a large current discharge, which obviously causes serious ablation inside the injection device and greatly reduces the service life, thus affecting the stability of the device. Significant impact on performance and reliability. [0003] The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does n...
