Abstract
The invention discloses a heating and dehumidifying device for a distribution box. The heating and dehumidifying device comprises a distribution box body. An air duct is arranged in the distribution box body. An iron plate is arranged at the bottom of one end of the air duct, a draught fan and a heater are installed on the iron plate in a combined mode, and blades of the draught fan right face the heater. The outer wall of the other end of the air duct is provided with a plurality of air outlet holes in different directions. The draught fan and the heather are connected with a temperature controller, and a temperature and humidity sensor is arranged in the distribution box body and connected with the temperature controller. The heating and dehumidifying device overcomes the defect that an existing heating device is uneven in heating, unsafe because of exposure and low in heating and dehumidifying speed, and has the advantages of being capable of quickly and evenly removing humidity in the distribution box, low in cost and the like.
Description
Technical field
The invention belongs to field of electrical equipment, more specifically relate to a kind of power distribution cabinet heating and dehumidification device.
Background technology
At present in high-voltage board, dehumidifying heater is all to adopt a heater is directly installed on cabinet inwall, heater is directly fixed on the inwall of cabinet to heater or directly manually control heating by switch; Or adopt thermostat automatically to control heating.When heater assembly heating at present, slowly, local temperature is high in temperature diffusion, and heater exposes unshielded.At present all using heater is a square aluminium alloy device with many fin, has installing hole on device, is directly fixed on the inwall of switch cubicle with screw.
And existing technology has the following disadvantages: because the very large area of some humidity is in some season, because the sharply variation of temperature easily forms condensation in power distribution cabinet, steam deposits and easily causes electric short circuit to cause accident in cabinet.
Summary of the invention
The object of this invention is to provide and a kind ofly can remove fast, uniformly the moisture in power distribution cabinet, and the low power distribution cabinet heating and dehumidification device of installation cost.
A kind of power distribution cabinet heating and dehumidification device of the present invention, comprises distribution cabinet, in distribution cabinet, is provided with air duct, and the bottom, one end of described air duct is provided with iron plate, and on iron plate, combination is provided with blower fan and heater, and the fan blade of blower fan faces heater; The other end outer wall of air duct is provided with the exhaust vent of many different directions; Described blower fan is connected thermostat jointly with heater, is also provided with Temperature Humidity Sensor transducer in distribution cabinet, and is connected with thermostat.
Further improve, described air duct is a circular steel pipe fittings.
Further improve, described deduster is strap deduster.
Further improve, it is external that described thermostat is arranged on power distribution cabinet.
Beneficial effect of the present invention is:
Compared with prior art, heating and dehumidification device of the present invention, has overcome heater heating in the past uneven, and heater exposes dangerous, the drawback that heating and dehumidification is slow.The present invention has the advantages such as moisture, the installation cost that can remove fast, uniformly in power distribution cabinet are low.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of power distribution cabinet heating and dehumidification device of the present invention, comprises distribution cabinet 1, in distribution cabinet 1, be provided with air duct 2, the bottom, one end of described air duct 2 is provided with iron plate 3, and on iron plate 3, combination is provided with blower fan 4 and heater 5, and the fan blade of blower fan 4 faces heater 5; The other end outer wall of air duct 2 is provided with the exhaust vent 6 of many different directions; Described blower fan 4 is connected thermostat 7 jointly with heater 5, is also provided with Temperature Humidity Sensor transducer 8, and is connected with thermostat 7 in distribution cabinet 1.
Described air duct 2 is a circular steel pipe fittings; Described thermostat 7 is arranged on outside distribution cabinet 1.
The invention provides a kind of power distribution cabinet heating and dehumidification device; the above is only preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improve and also should be considered as protection scope of the present invention.
