Background technology
Dual power supply low-tension switch cabinet i.e. a kind of switch cubicle for being provided with two-way power supply, generally power supply is connect by civil power all the way
Enter, another way power supply is accessed by Generators.The mutual conversion of two-way power supply is realized by dual-power transfer switch, to meet not
Same use demand.Existing dual power supply low-tension switch cabinet is generally only provided with an air inlet and an air outlet, cold air
Entered by air inlet in cabinet, then hot-air is extracted out by the radiator fan at air outlet and realizes cooling outside cabinet.But this side
Formula can not often meet radiating requirements of the equipment in heavy-duty service.For this conventional mode be set on cabinet it is multiple enter
Air port, cold air enter simultaneously from multiple air inlets, so as to improve the effect of cooling.But this way still has certain lack
Fall into, because multiple air inlets are chronically at the state of opening, extraneous dust and steam easily enter in cabinet from air inlet, made
Equipment is damaged in into cabinet.Although can be by setting screen pack still not ideal enough come blocks dust, effect in air inlet.
Utility model content
The purpose of this utility model is to provide a kind of dual power supply with high heat dispersion that can adapt to different operating modes automatically
Automatic heat radiation Intelligent low-voltage switchgear.
To achieve the above object, the technical solution adopted in the utility model is：A kind of dual power supply automatic heat radiation intelligent low-pressure
Switch cubicle, including cabinet, the top surface of the cabinet set air outlet, and it is in rectangular that the side of cabinet, which is from top to bottom uniformly arranged multiple,
The air inlet of shape；Radiator fan is set at the air outlet, the dustproof filter screen being engaged is set in the air inlet；On air inlet
The cabinet outer surface of side sets the hush panel that is engaged with air inlet, the cabinet outer surface setting electromagnet below air inlet；Institute
The edge for stating hush panel side is hinged by spring hinge and cabinet, and the position that opposite side corresponds to electromagnet sets permanent magnet；Institute
State and controller and temperature sensor be set inside cabinet, the temperature sensor is electrically connected with controller, the electromagnet by
Controller controls.
Preferably, the air inlet cabinet inner surface setting pendulum wind mechanism, it is described pendulum wind mechanism include wind deflector and
Rubber band, the edge of the wind deflector side are hinged with the cabinet inner surface of air inlet both sides, and the edge of opposite side is into cabinet
Portion extends；The plate face of wind deflector two sets rubber band respectively, and one end of the rubber band and wind deflector are affixed, the other end and cabinet
Inner surface is affixed, and the rubber band positioned at the plate face of wind deflector two is symmetrical.
The beneficial effect that the utility model possesses embodies a concentrated reflection of：Air inlet can be switched according to the different operating modes of switch cubicle
Opening number, both with excellent heat dispersion, can also reduce the risk for entering dust and steam in cabinet.Specifically,
In use, electromagnet is powered the utility model, produces huge suction between permanent magnet, drive hush panel close into
Air port.After electromagnet closing, hush panel opens air inlet by the elastic reset of spring hinge.In cabinet
The temperature that temperature sensor is used in real-time detection cabinet, in equipment heavy-duty service, that is, when temperature is higher, control
Device controls the electromagnet of multiple air inlets to work simultaneously, makes multiple air inlets while opens, so as to realize that multiple air inlets are same
Shi Jinfeng, cool ambient air and the heat exchange of hot-air in cabinet are promoted, and then improve the heat dispersion of switch cubicle.Just
Under normal use state, that is, when the temperature is low, controller controls the work of electromagnet of an air inlet, makes an air intake
Mouth is opened, so as to control the risk for entering dust and steam inside cabinet so that utility model works situation is more steady
It is fixed.Therefore, the utility model can meet equipment according to the unlatching quantity of the different operating mode reasonable selection air inlets of switch cubicle
Radiating requirements when different load is run, there is higher intelligent level.
