Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for specification, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of rotation electrode gas spark of the present invention gap switch.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of rotation electrode gas spark gap switch, comprises top electrode, bottom electrode, upper insulation cover plate, lower insulation cover plate, insulating cylinder body, rotating shaft and target.
Insulating cylinder body has side opening, the upper end of insulating cylinder body is provided with annular upper electrode and is sealed by screw and sealing ring fixing, in the middle part of the ring surface of top electrode, have annular boss, in T-shaped, insulation cover plate to be embedded in annular boss and seal by screw and sealing ring with top electrode and fixes.
There is through hole at upper insulation cover plate center, and rotating shaft, through the through hole of upper insulation cover plate, is coordinated by the movable sealing of T-shaped sealing ring between rotating shaft with upper insulation cover plate, and T-shaped sealing ring is fixed by screw and sealed briquette and upper insulation cover plate.To coordinate equally between insulation cover plate with rotating shaft down.
Top electrode and bottom electrode, upper insulation cover plate and lower insulation cover plate are symmetrical arranged.
Form cavity between insulating cylinder body, top electrode, bottom electrode, upper insulation cover plate, lower insulation cover plate, the gas of inside cavity is passed in and out by the side pore of insulating cylinder body.Rotating shaft in cavity is provided with symmetrical and with the wing plate of rotational axis vertical, wing plate end is fixed with target, and left and right target is setting up and down at wing plate respectively.
During work, upper and lower electrode loads rated voltage, under the effect of air motor, rotating shaft is with certain rotational speed, drive target rotates, and rotating shaft is a trigger electrode simultaneously, when loading certain pulse-triggered voltage on the rotary shaft, target to upper and lower electrode conduction, gas ionization in conducting region.When next trigger impulse arrives, due to the rotation of target, switch conduction position is different from previous conduction position, is conducive to the recovery of previous ionization channels.Cannelure in upper and lower insulation cover plate and insulating cylinder body, is conducive to increasing creepage distance, reduces switch surface breakdown probability.
