Abstract
The utility model relates to a switch cabinet with a pressure relief safety device, which comprises a top plate, wherein the top plate is fixedly arranged at the top of the switch cabinet, the top plate is provided with a gas release hole, a shielding plate is arranged on the top plate and above the gas release hole, and the shielding plate is connected above the top plate through a plurality of connecting pieces; the connecting piece includes at least one movable connecting piece and at least one fixed connecting piece, but movable connecting piece is disconnection under the effect of great pressure in the cabinet, and fixed connecting piece still keeps fixed connection under the effect of great pressure in the cabinet. According to the switch cabinet with the pressure relief safety device, when arcing faults occur, expanded air in the cabinet body is discharged from the air leakage hole in the top plate of the switch cabinet, and if a small amount of expanded air is discharged from the air leakage hole, the switch cabinet with the pressure relief safety device is provided. If a large amount of inflation air, powerful pressure makes the swing joint spare disconnection, and three swing joint spare disconnection back air can discharge more smoothly to can prevent that the cubical switchboard cabinet door from being exploded, avoid producing great bodily injury and loss of property.
Description
Technical Field
The utility model relates to a cubical switchboard field, especially a take pressure release safety device's cubical switchboard.
Background
The switch cabinet is an electrical device and mainly used for opening, closing, controlling and protecting the electrical device in the process of generating, transmitting, distributing and converting electric energy of an electric power system. Because high-low voltage switch cabinet is the equipment of a high pressure or low-voltage cable, consequently when the accident appears, when the inside arcing trouble that takes place of cubical switchboard, the interior temperature of cabinet can sharply rise, and air inflation can lead to cubical switchboard cabinet door to be fried, can cause the harm to the person and property. How to avoid or reduce the damage caused by arcing becomes a difficult problem.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a take cubical switchboard of pressure release safety device, it includes the roof, the roof sets firmly in the top of cubical switchboard, be equipped with the disappointing hole on the roof, be located the top in disappointing hole on the roof and be equipped with the sunshade, the sunshade is connected above the roof through a plurality of connecting pieces; the connecting piece comprises at least one movable connecting piece and at least one fixed connecting piece, the movable connecting piece can be disconnected under the action of larger pressure in the cabinet, and the fixed connecting piece still keeps fixed connection under the action of larger pressure in the cabinet.
Further, the movable connecting piece comprises a connecting piece, and the connecting piece is connected to the shielding plate through a plastic screw.
Further, the fixed connecting piece comprises a connecting piece which is connected to the shielding plate through a metal bolt.
Further, the web has a height such that the shield is spaced a distance from the top plate.
Furthermore, the connecting piece is Z-shaped, the upper end face of the connecting piece is connected to the shielding plate, and the lower end face of the connecting piece is connected to the top plate.
Furthermore, the number of the movable connecting pieces is 3, the number of the fixed connecting pieces is 1, and the movable connecting pieces and the fixed connecting pieces are respectively connected to four corners of the shielding plate.
Furthermore, the top plate comprises a through hole, and a screen plate with an air leakage hole is arranged on the through hole.
The utility model discloses this kind of take pressure release safety device's cubical switchboard, when the arcing trouble appears, the internal expanding air of cabinet discharges from the hole that loses heart on the cubical switchboard roof, if a small amount of inflation air from the hole that loses heart discharge can. If a large amount of inflation air, powerful pressure makes the swing joint spare disconnection, and three swing joint spare disconnection back air can discharge more smoothly to can prevent that the cubical switchboard cabinet door from being exploded, avoid producing great bodily injury and loss of property. The remaining one of the fixed connectors still secures the cover to the top plate, thereby preventing the cover from separating and injuring the person. The utility model discloses simple structure, low in production cost, but actual protection effect is showing, has application prospect.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is an explosion diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to the attached drawings 1-2, the utility model discloses this kind of take pressure release safety device's cubical switchboard, it includes roof 1, roof 1 is equipped with a plurality of bolt holes 11 all around, can set firmly roof 1 in the top of cubical switchboard through a plurality of bolt. Including a through-hole 12 on the roof 1, the welding has a otter board 2 on the through-hole 12, is equipped with the disappointing hole 21 of a plurality of on the otter board 2, and the excessive inflation air can be followed and is lost the discharge cabinet body in the hole 21.
A shielding plate 3 is arranged above the air leakage hole on the top plate 1, and the shielding plate 3 is connected above the top plate 1 through a plurality of connecting pieces; the connecting piece comprises at least one movable connecting piece and at least one fixed connecting piece, the movable connecting piece can be disconnected under the action of larger pressure in the cabinet, and the fixed connecting piece still keeps fixed connection under the action of larger pressure in the cabinet.
The movable connecting piece comprises a connecting piece 4, the connecting piece 4 is connected to the shielding plate 3 through a plastic screw 41, and a bolt hole 31 for fixing the connecting piece 4 is formed in the shielding plate 3. The fixed connection comprises a connecting piece 4, said connecting piece 4 being connected to the cover 3 by means of a metal bolt 42. The connecting piece 4 has a height such that the shielding plate is spaced apart from the top plate by a certain distance, in this embodiment, the connecting piece 4 is Z-shaped, the upper end surface of the Z-shaped connecting piece is connected to the shielding plate 3, the lower end surface of the Z-shaped connecting piece is connected to the top plate 1, and the neck of the Z-shaped connecting piece spaces the shielding plate from the top plate by a certain distance.
