Description
Technical field
This utility model belongs to a kind of high-tension distribution equipment, specifically, particularly relates to a kind of being provided with in Novel pressure relief device and puts
Cabinet.
Background technology
Switch cubicle, in running, causes once (such as short circuit, insulation ag(e)ing, human operational error etc.) because of various reasons
Loop short trouble occurs, and under the short circuit current of tens thousand of amperes, moment produces high temperature and high pressure gas, if high temperature and high pressure gas exists
Can not effectively discharge in very short time in narrow cabinet, switch cubicle can be caused to burst, adjacent switch cabinet damages, and may simultaneously
Injure personal safety.Therefore, switch cubicle is when design, it is necessary to consider effective pressure-relief measure.Existing pressure relief device includes that one is long
Square metal top board, its side iron screw fixes, and opposite side nylon screw is fixed.When breaking down in cabinet, top board becomes
Shape is opened, and release pressure and vented gasses, after pressure release, top board is scrapped.This pressure relief device needs switch cubicle internal circuit short circuit blast to produce
Raw gas pressure is the biggest just can make plastic bolt damage, and safety is low, and venting duration is slow, and after pressure release, pressure relief plate becomes
Shape can not reset, and needs again to change pressure relief plate, and maintenance cost is high, operates with inconvenience.
Utility model content
This utility model purpose is to provide the one that a kind of safety is high, pressure release is fast, maintenance cost is low, easy for operation and is provided with
The middle-placed switch cabinet of Novel pressure relief device, to overcome drawbacks described above of the prior art.
This utility model realizes by the following technical solutions: a kind of middle-placed switch cabinet being provided with Novel pressure relief device, including the highest
Spending consistent cabinet, be provided with central dividing plate inside described cabinet, described central dividing plate side is provided with control room, breaker chamber, electricity
Cable room, is provided with handcart in described breaker chamber, opposite side is provided with bus-bar room, earthed switch, and described earthed switch is fixed on centre
The lower section of dividing plate, described cabinet is arranged over pressure relief device, and described pressure relief device includes pressure release passage and pressure release cover, described pressure release
Channel connection control room, breaker chamber and bus-bar room, described pressure release is located at the top of pressure release passage and is connected to cabinet by screw rod
On body, described screw rod is cased with spring.
Described cabinet is provided with the relief hole installing check valve.
Bus in described bus-bar room is that vertical in-line is arranged.
Described control room is structure as a whole with cabinet.
Described cabinet depth is 1600mm-1800mm.
Compared with prior art, the beneficial effects of the utility model are: this utility model has simple in construction, easy to use excellent
Point, can quickly pressure release automatically, venting duration is short, improves safety, it is also possible to reuse pressure relief device, reduces
Maintenance cost.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of middle-placed switch cabinet being provided with Novel pressure relief device, including the cabinet 1 that anterior and posterior height is consistent, in cabinet 1
Portion is provided with central dividing plate 4, and central dividing plate 4 side is provided with control room 2, breaker chamber 6, cable vault 8, sets in breaker chamber 6
Having handcart 7, opposite side is provided with bus-bar room 5, earthed switch 9, and earthed switch 9 is fixed on the lower section of central dividing plate 4, bus-bar room
Bus in 5 is that vertical in-line is arranged, control room 2 is structure as a whole with cabinet 1.
As in figure 2 it is shown, pressure relief device includes pressure release passage 10 and pressure release cover 3, pressure release passage 10 connects control room 2, chopper
Room 6 and bus-bar room 5, pressure release cover 3 is located at the top of pressure release passage 10 and is connected on cabinet 1 by screw rod 11, screw rod 11
On be cased with spring 12, when the gases at high pressure being short-circuited fault in switch cubicle and produce, gases at high pressure are by pressure release cover 3 jack-up also
Compression spring 12, after pressure release, pressure release cover 3 covers on pressure release passage 10 under spring 12 restoring force effect automatically, pressure release cover 3
Can utilize with repetitive cycling.
Cabinet 1 is provided with the relief hole installing check valve, further enhancing pressure release speed, and avoids extraneous humid air
Enter the interior harmful effect to electronic component of cabinet 1.
Cabinet 1 degree of depth is 1600mm-1800mm, and overhead outlet cabinet is when main transformer cabinet busbar crane span structure inlet wire, and live part is to bus
The coverage of room 5 back plate is more than 125mm, and cabinet 1 degree of depth in the range of this can meet safe distance requirement.
