Abstract

The invention discloses an arc-extinguishing device suitable for a switch cabinet. The arc-extinguishing device suitable for the switch cabinet is characterized by comprising a supporting insulator, an arc-extinguishing grid frame, arc-extinguishing grid sheets, a spindle and a wafer, wherein the arc-extinguishing grid frame is fixedly arranged on the supporting insulator by screws; the arc-extinguishing grid frame is provided with a plurality of clamping troughs; the bottom ends of the arc-extinguishing grid sheets are inserted into the clamping troughs to be fixed; at least one of the ends of the arc-extinguishing grid sheets is not tidily arranged; the wafer and the spindle are movably connected. The arc-extinguishing device suitable for the switch cabinet, which is disclosed by the invention, has the beneficial effects that the arc-extinguishing grid sheets are fixed by the clamping troughs, so distance among the arc-extinguishing grid sheets is reduced, the amount of the arc-extinguishing grid sheets is increased, the arc-extinguishing capability can be enhanced, and installation is firmer; the arc striking capability is increased by untidy arrangement of the ends of the arc-extinguishing grid sheets.

Description

A kind of arc-control device that is applicable to switch cubicle
Technical field
The present invention relates to electrical power distribution switches cabinet field, particularly relate to a kind of arc-control device that is applicable to switch cubicle.
Background technology
No matter at home still abroad, 50kV and following equipment for power transmission and distribution have become direct or substantially direct user oriented terminal equipment, therefore very high to stability and the reliability requirement of the normal operation of switch cubicle, and to switch cubicle, safe, the convenient problem in periodic maintenance, maintenance, debug process has proposed higher, more reliable requirement.
In switch cubicle, switching device can produce certain electric arc when cut-offfing, if can't be put out timely and effectively, probably causes injury to personnel, has potential safety hazard.Normally adopt in the prior art the arc quenching chamber structure of arc-chute, the arc extinguishing grid pieces longitudinal arrangement of existing arc-chute, and the termination of arc extinguishing grid pieces is neat, it is large that this makes electric arc enter the comparison of resistance of arc-control device, is unfavorable for that electric arc enters.
Summary of the invention
Purpose of the present invention is exactly in order to address the above problem, and has proposed a kind of arc-control device that is applicable to switch cubicle.
To achieve these goals, the present invention adopts following technical scheme:
A kind of arc-control device that is applicable to switch cubicle comprises: supporting insulator, arc-chute frame, arc extinguishing grid pieces, rotating shaft and contact; Described arc-chute frame is screwed on supporting insulator, be provided with some draw-in grooves on described arc-chute frame, described arc extinguishing grid pieces bottom is inserted in described draw-in groove fixing, and the termination of described arc extinguishing grid pieces has one at least for irregular arrangement, and described contact and described rotating shaft are flexibly connected.
Described arc extinguishing grid pieces adopts the magnetic A20 steel plate of tool, copper coating.
The low side of described contact is 1/4 round.
Beneficial effect of the present invention:
By the fixing arc extinguishing grid pieces of draw-in groove, reduced the distance between arc extinguishing grid pieces, increased the quantity of arc extinguishing grid pieces, can increase the arc extinguishing ability, make to install more firm; By the irregular arrangement in arc extinguishing grid pieces termination is set, increased the striking ability.
The accompanying drawing explanation
The structural representation that Fig. 1 is arc-control device of the present invention.
Wherein, 1. supporting insulator, 2. arc extinguishing grid pieces, 3. arc-chute frame, 4. contact, 5. rotating shaft.
Embodiment:
Below in conjunction with accompanying drawing and embodiment, the present invention will be further described:
A kind of arc-control device that is applicable to switch cubicle comprises: supporting insulator 1, arc-chute frame 3, arc extinguishing grid pieces 2, rotating shaft 5 and contact 4; Described arc-chute frame 3 is screwed on supporting insulator 1, be provided with some draw-in grooves on described arc-chute frame 3, described arc extinguishing grid pieces 2 bottoms are inserted in described draw-in groove fixing, and the termination of described arc extinguishing grid pieces 2 has one at least for irregular arrangement, and described contact 4 is flexibly connected with described rotating shaft 5.
Described arc extinguishing grid pieces 2 adopts the magnetic A20 steel plate of tool, copper coating.
The low side of described contact 4 is 1/4 round.
The blow-out mode of this structure electric arc adopts metal deionization coral, the electric arc that will cut-off rear generation is controlled in the breath arc chamber be comprised of arc extinguishing grid pieces 2 fully, and design arc ignition face in breath arc chamber, electric arc is controlled on the coral sheet, interrupt electric arc by multilayer coral sheet, thereby reach quick breath arc purpose.
Its arc extinguishing grid pieces 2 adopts magnetic A20 steel plate preferably, copper coating, and suction arc ability is good, and electric arc rule shape distributes.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.

Claims (3)
