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, the top of described control room, bus-bar room and breaker chamber is equipped with pressure relief device, and described pressure relief device includes letting out
Pressure passageway and pressure release top board, the side of described pressure release top board is connected through the hinge, and opposite side is provided with magnetic force block, described pressure release top board
Hinged end be provided with postive stop baffle.
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, and reduces maintenance cost.
