Abstract
The invention discloses a switch cabinet provided with a pressure relief device. The switch cabinet comprises a gas tank, a cable chamber and a pressure relief chamber; the gas tank is arranged on a left lateral plate and a right lateral plate of a cabinet body; the cable chamber is enclosed by the left lateral plate and the right lateral plate of the cabinet body, a front lower door plate and a middle partition plate; the pressure relief chamber is composed of the left lateral plate and the right lateral plate of the cabinet body, a middle partition plate and a rear seal plate; a pressure relief hole is arranged on a bottom plate of the pressure relief chamber; a one-way pressure relief hole which just can be opened towards the pressure relief chamber is arranged at the lower part of the middle partition plate between the cable chamber and the pressure relief chamber; the pressure relief hole connected with the other switch cabinet groups is arranged at the lower part of the right lateral plate of the pressure relief chamber; if the cabinet is independently used, a sealing plate deadly seals the pressure relief hole. Compared with the prior art, the problem that high-voltage gas generated when the gas tank explodes by an accident or a cable explodes due to sudden failure cannot be immediately discharged out of the cabinet is solved.
Description
Technical field
The present invention relates to the safety relief mode technical field of switch cubicle, particularly a kind of switch cubicle that is provided with pressure relief device.
Technical background
Current, in the sulfur hexafluoride gas-insulating ring main unit in the 12kV/24kV distribution system, when the explosion time that breaks down; The gases at high pressure that produced like blast can not get dredging timely; It is inner all to accumulate in cabinet, might the product abolish be led to bigger security incident.And existing gas tank formula ring main unit can not be discharged the gases at high pressure that the fault blast is produced outside the cabinet because design and manufacturing defect do not have special pressure relief device timely, has major safety risks.
Summary of the invention
Problem to be solved by this invention provides a kind of outer switch cubicle that is provided with pressure relief device of discharge cabinet of the gases at high pressure of can be in time, apace the fault blast being produced.
To achieve these goals; Technical scheme of the present invention is: this switch cubicle that is provided with pressure relief device includes the cable vault that is connected under the gas tank; Cable vault's one side under said gas tank is provided with the pressure releasing chamber that is connected on outside the said gas tank pressure relief opening, has the base plate relief hole on the base plate of said pressure releasing chamber; Median septum between said cable vault and the said pressure releasing chamber is provided with and has the dividing plate relief hole, and air-flow flows to said pressure releasing chamber from said cable vault check valve sheet is housed on this dividing plate relief hole.
In the technical scheme of the above-mentioned switch cubicle that is provided with pressure relief device, can also be more specifically: be provided with at the side plate of said pressure releasing chamber and be used for the side relief hole that is communicated with other switch group cabinet.
Owing to adopted such scheme, the present invention compared with prior art has following beneficial effect:
1, the pressure release passage of pressure releasing chamber all is to be sealed in the independent interval by aluminizing zinc metallic plate, simultaneously, is cable trough under its pressure relief opening, and the gas tank pressure release can directly be walked toward the cable trough direction, and is simple in structure, easy to make;
2, the pressure release passage of cable vault also is to be sealed in a three side sealing by aluminizing zinc metallic plate to close in the interval; The relief hole that is provided with unidirectional conducting on the median septum that leads to the rear portion pressure releasing chamber only; The gas that produces during fault can be toward the front end punching press; Can only arrive cable trough through the rear portion pressure releasing chamber, discharge outside the cabinet, as safe as a house reliable.
Two kinds of above passages are separate, can complement each other again when breaking down, and further improved security reliability.
Description of drawings
Fig. 1 is the front view that the embodiment of the invention is provided with the switch cubicle of pressure relief device.
Fig. 2 is the vertical view cutaway drawing that the embodiment of the invention is provided with the switch cubicle of pressure relief device.
Fig. 3 is the backsight cutaway view of the embodiment of the invention switch cubicle that is provided with pressure relief device.
Embodiment
To combine the concrete accompanying drawing embodiment of the present invention that the present invention is described in further detail below.
Fig. 1, Fig. 2 and the switch cubicle that is provided with pressure relief device shown in Figure 3 have a gas tank 2; Below gas tank 2, be connected to a cable vault 1 and a pressure releasing chamber 14; Terminate on the pressure releasing chamber 14 on said gas tank 2 pressure relief openings 3, have base plate relief hole 15 on the base plate of pressure releasing chamber 14; Isolated between cable vault 1 and the pressure releasing chamber 14 by median septum 4; On median septum 4, be provided with the dividing plate relief hole; Pressure releasing chamber 14 1 sides at median septum 4 are connected with check valve sheet 6 through hinge 5; Check valve sheet 6 is greater than the dividing plate relief hole, makes the explosion air-flow of cable vault 1 can be from the cable vault 1 get into pressure releasing chamber 14 through the dividing plate relief hole, gets into cable vault 1 and can not let the explosion air communication of pressure releasing chamber 14 cross the dividing plate relief hole.On the side plate 12 of pressure releasing chamber 14, also be provided with and be used for the side relief hole 8 that is communicated with other switch cubicle, can let other switch cubicle explosion gas discharge from the pressure releasing chamber 14 of this cabinet.When if this cabinet does not need with his group cabinet, side relief hole 8 can be used shrouding 7 sealings.
