Description
Technical field
The utility model belongs to the technical field of distribution box, more particularly to ventilation, dedusting and can avoid power circuit
HTHP caused by short circuit causes a kind of low-tension distribution box for multiple-protection that distribution box burns.
Background technology
Distribution box is to be assembled in switchgear, measuring instrumentss, protection electrical equipment and auxiliary equipment according to electrical wiring requirement
In closing or semiclosed metal safe or in screen width, it arranges the requirement that should meet power system normal operation.Installed in distribution box
There is substantial amounts of component, the lasting high-speed cruising of component can cause the substantial amounts of heat of accumulation in distribution box, inside distribution box
When temperature is too high, component will be unable to normal work, or even burn component, and therefore, distribution box must be equipped with ventilation unit, but
Traditional ventilation unit can not avoid dust from entering inside fitting case, and the element longtime running inside distribution box will be covered with ash
Dirt, dusty component easily occur short circuit, cause equipment to be not normally functioning.
And existing power distribution cabinet is sealing, the electrical equipment of distribution intracavitary at work, can produce substantial amounts of heat, nothing
Method realizes effectively radiating；And during the distribution intracavitary short-circuit arcing failure of generation, high temperature, high pressure can be produced in distribution intracavitary moment；
If when power distribution cabinet degree of protection is higher, this pressure smoothly can not be discharged into outside cabinet, and distribution cabinet may be caused to be permanently deformed,
Even cabinet door is blown up, and can have larger potential safety hazard.
Therefore, it is necessary to which one kind can meet air-conditioning requirement, and can meets the distribution box of dust-proof release of pressure requirement.
Utility model content
