Abstract
A kind of double power supply automatic transfer switch arc-extinguish chamber with guard member, including mounting bracket, the mounting bracket is set to N shapes, the side of left and right two is vertical outer wall, centre is connected by a skew wall, in the described side of skew wall two, one arc-chutes is respectively set, arc quenching plate is provided with described arc-chutes, guard member is provided with nock in entering for the arc quenching plate, on the one hand, the guard member can effectively protect arc-chutes to enter nock and the arc quenching plate entered at nock, reduce and enter at nock to enter arc-chutes the damage that nock and the arc quenching plate entered at nock are produced in high temperature, on the other hand, because the guard member can produce hydrogen at a high temperature of arc spraying, simultaneously because guard member it is interior be set to along side it is small into nock, go out the big isosceles trapezoid of nock, add arc-chutes and enter at nock to enter arc speed, these are all conducive to the arc extinguishing of arc-extinguish chamber.
Description
Technical field
Turn automatically the present invention relates to a kind of low voltage switch arc-extinguish chamber, more particularly to a kind of dual power supply with guard member
Change switch arc-extinguish chamber.
Background technology
Double power supply automatic transfer switch is a kind of conventional low-voltage electrical apparatus, is usually used in the conversion between two road power supplys, to protect
Card is when power failure all the way or when stopping power supply, and another road power supply can be switched over rapidly, to ensure that load circuit is normal
Power supply.The shift actuating member of PC grades of double power supply automatic transfer switch is generally change-over switch, in conventional power supply and stand-by power supply
Dynamic and static contact between be provided with an arc-extinguish chamber, the arc-extinguish chamber of traditional double power supply automatic transfer switch is in contact disjunction when institute
The electric arc of generation injects directly on arc-chutes and enters nock and enter on the arc quenching plate at nock, it is easy to will enter nock and enters at nock
Arc quenching plate burn out.
The content of the invention
It is an object of the invention to overcome traditional double power supply automatic transfer switch arc-extinguish chamber to enter nock and arc quenching plate easily to burn
Bad the drawbacks of, disclosing a kind of can protect the double power supply automatic transfer switch arc-extinguish chamber of arc-chutes and arc quenching plate.
In order to realize the above object the technical solution adopted by the present invention is：A kind of double power-supply automatic transferring with guard member
Arc-extinguish chamber, including mounting bracket are switched, described mounting bracket is set to N shapes, and the side of left and right two is vertical outer wall, and centre is by a skew wall
It is connected, one arc-chutes is respectively set in the described side of skew wall two, arc quenching plate is provided with described arc-chutes, in the arc extinguishing
Entering for room arc quenching plate is provided with guard member at nock.
Further set, described guard member is that the insulating materials that can produce hydrogen at high temperature is integrally suppressed and formed.
Further set, described guard member is set to interior empty rectangular body, and right side is provided with mounting ear, by installing
Riveting post rivet hot of the mounting hole that mounting hole and left side on ear are set with being set on the mounting bracket is formed.
Further set, outer side and the arc-chutes of the guard member, which enter at nock, to coincide, interior to be set to along side
Waist is trapezoidal, and it is small side to enter at nock, and it is big side to go out at nock.
The present invention is had an advantageous effect in that：Due to entering in arc-chutes at nock there is provided guard member, on the one hand, the guarantor
Guard can effectively protect arc-chutes to enter nock and the arc quenching plate entered at nock, reduce and enter at nock to enter arc-chutes in high temperature
The damage that nock and the arc quenching plate entered at nock are produced, on the other hand, because the guard member can be produced at a high temperature of arc spraying
Raw hydrogen, simultaneously because guard member it is interior along side be set into nock it is small, go out the big isosceles trapezoid of nock, add arc-chutes and enter
Enter arc speed at nock, these are all conducive to the arc extinguishing of arc-extinguish chamber.
