Background
The low-voltage switch cabinet is suitable for industries such as power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and the like, and is used for power transmission, power distribution and electric energy conversion. After the low-voltage switch cabinet inner conductor flows through, a current heat effect is generated, and the temperature of the surface of the conductor continuously rises until the temperature is stable along with the time. This portion of the rising temperature that exceeds the temperature of the surrounding air (ambient temperature) is called the temperature rise. The insulating property of the components can be reduced when the components in the cabinet are in a high-temperature state for a long time, and the service life of the components is shortened.
At present, the heat dissipation of the cabinet top of a low-voltage switch cabinet in the market mostly adopts single-layer heat dissipation holes, however, the design can not well play a dustproof role, the components and parts can absorb moisture in the air after being covered by dust, the components and parts which are partially exposed can be corroded, and the faults of insulation reduction, short circuit, grounding and the like can be caused for a long time. And the top of the cabinet is directly sealed to play a role in heat dissipation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a dustproof top cap of heat dissipation of indoor low-voltage switchgear to there is dustproof poor problem of effect in the heat dissipation top cap of solving indoor low-voltage switchgear among the prior art.
To achieve the purpose, the utility model adopts the following technical proposal:
the utility model provides a dustproof top cap of heat dissipation of indoor low-voltage switchgear, its includes the cubical switchboard body and heat dissipation top cap, the vent has been seted up on the top of the cubical switchboard body, heat dissipation top cap assemble in vent department, just the heat dissipation top cap includes upper heating panel and lower floor's heating panel, a plurality of upper louvre has been seted up on the upper heating panel, a plurality of lower floor's louvre has been seted up on the heating panel of lower floor, upper heating panel and lower floor's heating panel pass through the connecting piece assembly as an organic whole, and upper louvre and lower floor's louvre crisscross setting each.
Particularly, one end of the heat dissipation top cover can be rotatably installed at the top end of the switch cabinet body through a plurality of hinges, and the other end of the heat dissipation top cover can be detachably assembled at the top end of the switch cabinet body through a connecting screw.
Particularly, a cabinet front drainage groove is formed in the part, close to the front face of the switch cabinet, of the top end of the switch cabinet body along the width direction of the switch cabinet front drainage groove.
Particularly, all the punching press forms the bellying of a plurality of rectangular shape on upper heat dissipation board and the lower floor's heat dissipation board, the louvre sets up in the both ends of bellying, and upper strata heat dissipation board and the crisscross distribution of bellying of lower floor's heat dissipation board after the assembly both form certain heat dissipation chamber between the two-layer heat dissipation board through the bellying.
Particularly, both ends of the upper-layer heat dissipation plate and the lower-layer heat dissipation plate are assembled into a whole through connecting screws.
The beneficial effects of the utility model are that, compare with prior art indoor low-voltage switchgear's dustproof top cap of heat dissipation has following advantage:
1, adopt double-deck heat dissipation plate structure, and the louvre staggered arrangement of two heating panels, under the circumstances of guaranteeing the radiating effect, the dust gets into from upper louvre, and isolated on lower floor's heating panel, the clean components and parts of guaranteeing in the cabinet.
2, the upper and lower two-layer heating panel two unification, whole can be opened by one side, easy dismounting.
And 3, the water flow in front of the cabinet is converged in the front drainage groove of the cabinet and is discharged from two sides of the cabinet, so that no accumulated water is generated at the top end of the cabinet body.
