Abstract
The utility model discloses a device of putting off arc, including putting off arc the bars piece and the bars support of putting off arc, put off arc the bars piece for slice character cut in bas -relief shape metallic conductor, the both sides correspondence is equipped with the picture peg, the bars support of putting off arc is the square frame structure, and align to grid has a plurality of slot on it, the bars piece of putting off arc has a plurality of pieces just all to offer a plurality of hole on each, and the bars piece of respectively putting off arc is evenly inserted through the picture peg and is established at the ditch inslot of bars support of putting off arc, this device of putting off arc sets up the hole through the bars piece of putting off arc at every on the surface to having increased the surface area of the bars piece of putting off arc, having strengthened the mobility of electric arc, the closeness of further having disperseed electric arc has weakened the energy of electric arc, realizes the smooth arc extinguishing of switch, has improved the ability that load switch cut -offs the heavy current.
Description
Technical field
This utility model belongs to high-voltage switch gear field, is specifically related to a kind of spark blowout.
Background technology
SF 6 high-voltage on-load switch can produce electric arc during cut-offfing circuit, only arc extinction be can be only achieved disconnection
The purpose of circuit.Want smooth arc extinguishing in interrupting process, it is necessary to use spark blowout ability arc extinguishing, and then realize opening of circuit
Disconnected.Traditional arc-control device simple in construction, arc quenching effect is poor, it is achieved the current arc extinguishing of below 630A is no problem, but at 630A
In above current arc extinguishing, effect is poor.
Summary of the invention
In view of this, the purpose of this utility model is provide a kind of arc extinction performance good and be suitable for the spark blowout that current range is big.
For reaching above-mentioned purpose, this utility model following technical scheme of offer: a kind of spark blowout, including blow-out grid and blow-out
Grid support, described blow-out grid is sheet metal conductor, and both sides are correspondingly provided with plate, and described blow-out grid support is frame structure,
Evenly distributed on it have several grooves, if described blow-out grid has dry tablet, each blow-out grid is uniformly plugged in blow-out by plate
In the groove of grid support；
Described blow-out grid includes that extension and cartridge part, described extension have two, is correspondingly arranged at above cartridge part two ends also
Constituting lamellar concave shape structure with cartridge part, described plate is arranged on both sides, cartridge part；Described extension tip be circular arc and with
Rounding off between cartridge part, described cartridge part is evenly distributed with several holes.
Further, described blow-out grid has 10～15.
The beneficial effects of the utility model are: this spark blowout is by offering hole on the surface of each blow-out grid, thus increases
The big surface area of blow-out grid, enhances the mobility of electric arc, has disperseed the closeness of electric arc further, weakened electric arc
Energy, it is achieved switch smooth arc extinguishing, improves on-load switch and cut-offs the ability of big electric current；Principle is simple, compact structure, outside
Insulation effect is good, reduces manufacturing cost, good in economic efficiency.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, this utility model provides drawings described below to enter
Row explanation:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As it can be seen, the spark blowout in the present embodiment, including blow-out grid 1 and blow-out grid support 2, described blow-out grid 1
For sheet metal conductor, both sides are correspondingly provided with plate 11, and described blow-out grid support 2 is frame structure, has if evenly distributed on it
Dry groove, if described blow-out grid 1 has dry tablet, each blow-out grid 1 to be uniformly plugged in blow-out grid support 2 by plate 11
In groove；
Described blow-out grid 1 includes extension 12 and cartridge part 13, and described extension 12 has two, is correspondingly arranged at cartridge part
Two ends constitute lamellar concave shape structure with cartridge part 13 above in the of 13, described plate 11 is arranged on both sides, cartridge part 13；Described
Extension 12 top be circular arc and and cartridge part 13 between rounding off, described cartridge part 13 is evenly distributed with several holes
14.Concrete, the present embodiment increases the surface area of blow-out grid 1 by offering hole 14 on the surface of each blow-out grid 1,
Thus enhance the mobility of electric arc, disperse the closeness of electric arc further, weakened the energy of electric arc, it is achieved switch is smoothly
Arc extinguishing, reaches on-load switch and cut-offs the ability of big electric current.
As the further improvement of such scheme, described blow-out grid 1 has 10～15.By rationally determining blow-out grid 1 number
Amount, can make the blow-out performance of this spark blowout reach optimum good, thus improve arc quenching effect, improve the breaking capacity of on-load switch,
Realize the current arc extinguishing to below 1800A.
Finally illustrating, preferred embodiment above is only in order to illustrate the technical solution of the utility model and unrestricted, although passing through
This utility model is described in detail by above preferred embodiment, it is to be understood by those skilled in the art that can be
In form and it is made various change, without departing from this utility model claims limited range in details.
Claims (2)
1. a spark blowout, including blow-out grid and blow-out grid support, it is characterised in that: described blow-out grid is that sheet metal is led
