Abstract
The utility model discloses a pressure-relief dust-proof device for a switch cabinet. The key points are as follows: the pressure-relief dust-proof device comprises a pedestal (1) and a cover plate (2), wherein the pedestal (1) is arranged on a pressure relief channel and provided with a directional pressure relief hole; one side of the cover plate (2), which is covered on the pressure relief hole, is hinged with the pedestal (1), and the other side is fixed on the pedestal (1) through a nylon bolt (4). In the utility model, the strip hole pressure relief is converted into a pressure relief plate fixed with the nylon bolt in the explosion process; since the other end is provided with a hinge, the pressure relief plate can move up and down so as to completely relieve the pressure; and the pressure-relief dust-proof device can achieve the effect of 100% dust-proofing when the device operates normally, thereby preventing all the small dust particles from falling into the circuit breaker and from causing short circuit and explosion of the circuit breaker. The utility model has the characteristics of favorable dust-proof effect, favorable pressure-relief effect and the like.
Description
Technical field
The utility model relates to a kind of switch cubicle, relates in particular to the pressure relief device on the switch cubicle.
Background technology
Switch cubicle inner breaker chamber pressure relief plate all adopts the surface to break into the form of bar cellular type at present; Pressure relief plate welds the locked in pressure release passage of dead or metal bolts; When having an accident, the bar cellular type opening from pressure relief plate carries out pressure release, but the pressure relief plate of this cellular type; The effect of pressure release is unsatisfactory, and the safe operation of operating personnel, equipment and electrical network has been arrived in serious threat.Simultaneously, dust gets in the hole easily.
The utility model content
The purpose of the utility model provides the effective switch cubicle pressure release dust guard of a kind of pressure release.
To achieve these goals; Adopt following technical scheme: a kind of switch cubicle pressure release dust guard; It is characterized in that: said device comprises the base with direction relief hole that is arranged on the pressure release passage; Cover plate one side and the base that cover on the relief hole are hinged, and opposite side is fixed in cover plate on the base through nylon bolt.
Said base and cover plate are hinged through hinge.
When will blasting, the utility model made to wash open the pressure relief plate that is fixed with nylon bolt into through the cylindrical void pressure release; Because have hinge on the other end; Thereby so can be up and down pressure release fully, and when equipment normally moves, can reach 100% dustproof, prevent that all little grits from falling into the circuit breaker the inside and causing circuit breaker short circuit, blast; Have rational in infrastructure, characteristics such as dustproof pressure release is effective.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is an A-A cutaway view among Fig. 1;
State diagram after Fig. 2 changed when Fig. 3 was pressure release.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
Extremely shown in Figure 3 like Fig. 1; A kind of switch cubicle pressure release dust guard comprises through metal bolts or direct weldering and dies from the base 1 on the pressure release passage that the centre of base 1 is square relief hole; One side of relief hole has two width of cloth hinge mounting hole, and opposite side has two nylon bolt installing holes.The cover plate that has hinge mounting hole and nylon bolt installing hole 2 usefulness hinges 3 are fixed in cover plate on the base 1 with nylon bolt 4.
After accomplishing installation; Big grit perhaps can cause all materials of circuit breaker short circuit can't fall into breaker chamber; Even breaker body can be washed nylon bolt open through relief hole and open fully by cover plate and reach 100% pressure release because certain reason is blasted, guarantee operating personnel's safety.
Claims (2)
1. switch cubicle pressure release dust guard; It is characterized in that: said device comprises the base with direction relief hole (1) that is arranged on the pressure release passage; Cover plate (2) one sides and the base (1) that cover on the relief hole are hinged, and opposite side is fixed in cover plate (2) on the base (1) through nylon bolt (4).
2. switch cubicle pressure release dust guard as claimed in claim 1 is characterized in that: said base (1) is hinged through hinge (3) with cover plate (2).
