Principle and act on as follows that two-electrode gas switch coaxially flows back:
1)When gas switch is turned on, highpowerpulse current direction is:Ring flange → base combination of base combination 30 The electrode tip holder of electrode → top cover combination 10 of electrode gap → top cover combination 10 between 30 electrode → two electrode → upper lid Combine the ring flange → ten piece copper post of 10 cylindrical wall backflows → top cover combination 10 → highpowerpulse output;
2)Two electrode gaps are in the metal inner cavity of top cover combination 10, because conduction connecting structure is arranged on first electrode In the radial sidewalls of seat 11, and set location is located at the downside of electrode gap, in gas switch turn on process, top cover combination 10 metal inner cavity wall current directions are opposite with the current direction of two electrode gaps.According to the action principle of electromagnetic force, upper lid group The electromagnetic force of 10 metal inner cavity wall pulse currents generation is closed on the electric arc that two electrode gaps discharge, can be to two electrodes The electrical discharge arc in gap produces hoop beam force, and the hoop beam force causes electric arc when gas switch is turned on by hoop beam in coaxial metal structure In in narrow-minded region, in the region, transient temperature is higher, can reach 2000 ~ 4000K, the meeting of graphite molecule and cavity Oxidation reaction occurs for interior oxygen, becomes CO, CO2, after electric discharge terminates, is taken a breath by high pressure pure air, can be residual Gas and particle blow gas switch cavity, it is to avoid gas switch causes gas switch insulation resistance to because of the accumulative of residual conductive medium Pressure drop is low;Meanwhile, compared to the two-electrode gas switch without coaxial configuration, the gas of the coaxial return-flow structure of the application in the prior art During body switch conduction, pass through the electromagnetism hoop beam force that the Impulsive Current of outer metal barrel is inside so that electrical discharge arc is all each time It is in the border circular areas centered on coaxial configuration axle center, to stablize relatively, the conditions at the arc cause electrode surface by hard arc Ablation position is the border circular areas centered on coaxial configuration axle center, and electrode surface ablation degree tends to be uniform, and then improves two The service life of electrode gas discharge switch;The a small amount of graphite molecule produced during simultaneously turning on also can be by electromagnetic force hoop Beam is in the narrow region of coaxial metal structure centre, it is to avoid is splashed to pollution insulating concrete cylinder 20 on the inwall of insulating concrete cylinder 20, is kept away with this Exempt from influence of the electric arc of sputtering to insulating concrete cylinder 20, and then extend its life-span.In addition, in highpowerpulse current work situation Under, pass through the design that coaxially flows back, it is possible to increase two-electrode gas switch on/off electric dynamic balance and uniform, further lifting Large Copacity gas The arrangement works stability of body switch, and then raising gas switch electrically makees stability.
In the above-described embodiments, conduction connecting structure is using turning edge on first electrode seat is arranged on, in other embodiment In, conduction connecting structure can also replace with other forms, such as in electrode gap in the radial sidewalls of first electrode seat Lower section sets flange, and conductive pole is set on flange;In addition, conductive pole can also replace with other forms, such as wire;Again Person, conduction connecting structure can also be the structure being connected directly between in the radial sidewalls of first electrode seat, for example, pass through screw Or conductive anchor ear is conductively connected in the radial sidewalls of first electrode seat, can now be not provided with flange.In its of the present invention In his embodiment, in radial sidewalls and conduction connecting structure can also be set on bottom wall simultaneously on first electrode seat.
In the above-described embodiments, conductive pole is to be connected through a screw thread realization to fix, and in other embodiments, conductive pole also may be used To use other modes and first electrode conductive and fixed, for example, weld or pass through interference fit connection.
