The pressure relief plate adopts an overhead structure, the pressure relief plate is installed at the top of the low-voltage power distribution cabinet, and the pressure relief plate is provided with the vent holes, so heat radiation of the power distribution cabinet is convenient; and one side of the pressure relief plate is fixed to the low-voltage power distribution cabinet, the other side of the pressure relief plate is tightly pressed through the pressing strips, and fixing positions of the pressure relief plate and fixing positions of the pressing strips are provided with through holes, so when a fault of the internal of the power distribution cabinet occurs, convenience can be provided for high-temperature and high-pressure gases to be capable of rapidly breaking through the pressure relief plate, and then a protective function is played.
Description
Technical field
The utility model relates to a kind of pressure relief device, is specifically related to a kind of overhead type low-voltage distribution cabinet pressure relief device.
Background technology
The pressure relief plate of current existing low-voltage distribution cabinet, adopts the sheet material sealing conventionally, adopts steel securing member to fix on one side, adopts plastics screw on one side.In the time of internal fault, high-temperature gas and air pressure, force plastics broken screw or fusing, and pressure relief plate is opened thereupon, thereby plays a protective role.But, adopt the pressure relief device of this design, owing to being Seal Design, so, under normal operation, its radiating effect is very poor, and in heavy duty situation, temperature rise is higher, is unfavorable for the long-life safe operation of equipment.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved has been to provide a kind of simple and reasonable for structure, the overhead type low-voltage distribution cabinet pressure relief device of safe and reliable, good heat dissipation effect.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of overhead type low-voltage distribution cabinet pressure relief device, comprise pressure relief plate and press strip, described pressure relief plate is arranged on the top of low-voltage distribution cabinet, one side of pressure relief plate is fixed on low-voltage distribution cashier's office in a shop, one end of described press strip is fixed on low-voltage distribution cashier's office in a shop, and the other end is pressed in the opposite side of pressure relief plate to fix pressure relief plate, is also provided with multiple air vent holes on described pressure relief plate.
Preferably, one side of described pressure relief plate is provided with the first bolt hole, and the arranged direction along the first bolt hole on described pressure relief plate is also provided with multiple rectangular through-hole, and one end of described press strip is provided with the second bolt hole, on press strip, be also provided with square hole, described square hole is positioned at the outside of the second bolt hole.
Preferably, on the air vent hole of described pressure relief plate, be provided with bending bar.
In the utility model, pressure relief plate plate adopts overhead type structure; pressure relief plate is arranged on the top of low-voltage distribution cabinet; on pressure relief plate, have air vent hole; facilitate power distribution cabinet to dispel the heat, pressure relief plate one side is being fixed on low-voltage distribution cashier's office in a shop simultaneously, and opposite side compresses by press strip; all offer through hole in the fixed position of pressure relief plate and the fixed position of press strip; can conveniently break down in power distribution cabinet inside like this time, high temperature, gases at high pressure can break through rapidly pressure relief plate, thereby play a protective role.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of overhead type low-voltage distribution cabinet of the utility model pressure relief device.
Fig. 2 is the end view of pressure relief plate in the utility model.
In figure: 1 is pressure relief plate, 2 is press strip, and 3 is air vent hole, and 4 is the first bolt hole, and 5 is rectangular through-hole, and 6 is the second bolt hole, and 7 is square hole, and 8 is bending bar, and 9 is low-voltage distribution cabinet.
Embodiment
The specific embodiment of the utility model being done below in conjunction with accompanying drawing is described further.
As shown in Figure 1, a kind of overhead type low-voltage distribution cabinet pressure relief device, comprise pressure relief plate 1 and press strip 2, described pressure relief plate 1 is arranged on the top of low-voltage distribution cabinet, one side of pressure relief plate 1 is fixed on low-voltage distribution cashier's office in a shop, one end of described press strip 2 is fixed on low-voltage distribution cashier's office in a shop, and the other end is pressed in the opposite side of pressure relief plate 1 to fix pressure relief plate 1, is also provided with multiple air vent holes 3 on described pressure relief plate 1.Pressure relief plate 1 adopts overhead type structure, facilitates the hot gas in low-voltage distribution cabinet to rise, and dispels the heat, and improves radiating effect.
Particularly, one side of pressure relief plate 1 is provided with the first bolt hole 4, pressure relief plate 1 is bolted to low-voltage distribution cashier's office in a shop by the interior setting of the first bolt hole 4, in the position near the first bolt hole 4, multiple rectangular through-hole 5 are set simultaneously, rectangular through-hole 5 is arranged along the arranged direction of the first bolt hole 4, and arrange point-blank, the minimum spacing of rectangular through-hole 5 is no more than 1cm, same, press strip 2 one end are provided with the second bolt hole 6, the interior screw that arranges of the second bolt hole 6 is to fix press strip 2, position near the second bolt hole 6 arranges square hole 7, and square hole 7 is arranged on the outside of the second bolt hole 6, the other end of press strip 2 is pressed on pressure relief plate 1, and the length being pressed on pressure relief plate 1 is no more than 2cm, like this, in ensureing the normal heat radiation of low-voltage distribution cabinet, on can also breaking down in low-voltage distribution cabinet inside, high temperature, gases at high pressure break through pressure relief plate.Under the effect of high temperature, gases at high pressure, pressure relief plate 1 is in the bending of the position of rectangular through-hole 5, and press strip 2 is in the bending of the position of square hole 7, thereby makes pressure relief plate 1 under the effect of very little power, can open rapidly protection power distribution cabinet.
