By means of automatic humidity sensing and also heating and ventilation in the cabinet body, electronic elements in the cabinet body are prevented from being affected with damp so as to be prolonged in service life.
Description
Technical field
The present invention relates to power distribution infrastructure field, specifically a kind of electric cabinet dehumidifying device.
Background technology
Electrical control cubicles is built-in with multiple electric elements, and electric elements have basic moistureproof and waterproof requirement.Moisture vapor can accelerate the corrosion of components and parts, causes defective insulation, loose contact and electric leakage, thus reduces the serviceable life of electric elements, and, also can cause uncontrollable action, bring great hidden danger to safe operation.
Electrical control cubicles can produce moisture and condensate water under following several frequently seen situation: 1) electrical control cubicles protection is improper, and rain, snow, the dabbling of mist or outside, can enter into electrical control cubicles; 2) electrical control cubicles is in the top of cable duct, if having water in cable duct, the cable so generated heat will heat ponding, produces steam, produces condensate water on the surface in colder electrical control cubicles; 3) the southern time in rainy season, superheated vapor can produce condensate water on the surface in colder electrical control cubicles.
Above-mentioned several situation all can cause moisture in electrical control cubicles overweight, thus can produce condensate water in cabinet inside, causes great potential safety hazard to the operation of electric elements.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electric cabinet dehumidifying device, and this device by automatically responding to humidity and carrying out heating in cabinet and ventilating, thus avoids the electric elements in cabinet to make moist, and extends the serviceable life of electric elements in electrical control cubicles.
For solving the problems of the technologies described above, electric cabinet dehumidifying device of the present invention comprises cabinet, its design feature is that the bottom of described cabinet is separated out Lower Hold by base spacer, first electric heater is installed in Lower Hold, base spacer offers through hole, the top sidewall of cabinet is provided with blower fan, and cabinet inside is provided with humidity induction device, and the control end of the first electric heater and blower fan and the signal output part of humidity induction device are all electrically connected on a control circuit.
Preferably, described humidity induction device is humidity sensor.
Preferably, described blower fan arranges one respectively on the two side of cabinet.
Preferably, the top of described cabinet is separated out storehouse, top by roof spacer, and top is provided with the second electric heater in storehouse, and roof spacer offers through hole, and the control end electrical connection of the second electric heater on the control circuitry.
Preferably, described first electric heater and the second electric heater are electric heating wire type self-constant temperature well heater.
The invention has the beneficial effects as follows: utilize the humidity in humidity induction device Real-Time Monitoring cabinet, when humidity exceedes threshold value, control circuit controls to open electric heater and blower fan, electric heater is responsible for heating the air in cabinet, avoid moisture condensation, blower fan is used for moisture to discharge in time, thus can ensure cabinet inner drying, avoids electric elements to make moist; Blower fan respectively installs one in both sides, and ensure that air-flow is unobstructed, make dehumidifier better effects if, electric heater is respectively arranging a set of up and down, can heat the air of top and bottom respectively, ensures heating effect; Electric heater adopts self-constant temperature well heater, can carry out automatic temperature-adjusting control, ensures heated at constant temperature.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Embodiment
With reference to accompanying drawing, electric cabinet dehumidifying device of the present invention comprises cabinet 1, the bottom of cabinet 1 is separated out Lower Hold 3 by base spacer 2, first electric heater 4 is installed in Lower Hold 3, base spacer offers through hole, the top sidewall of cabinet 1 is provided with blower fan 5, and cabinet 1 inside is provided with humidity induction device 6, and the control end of the first electric heater 4 and blower fan 5 and the signal output part of humidity induction device 6 are all electrically connected on a control circuit 7.Wherein, humidity induction device 6 is humidity sensor.
With reference to accompanying drawing, in order to improve dehumidifier effect, blower fan 5 arranges one respectively on the two side of cabinet 1.Certainly, according to cabinet 1 structure and environment, blower fan 5 also can be arranged in other position of cabinet 1.
With reference to accompanying drawing, in order to improve heating effect, the top of cabinet 1 is separated out storehouse 9, top by roof spacer 8, and top is provided with the second electric heater 10 in storehouse 9, and roof spacer 8 offers through hole, and the control end of the second electric heater 10 is connected electrically on control circuit 7.First electric heater 4 and the second electric heater 10 are electric heating wire type self-constant temperature well heater.
The present invention utilizes the humidity of in humidity induction device 6 Real-Time Monitoring cabinet 1, when humidity exceedes threshold value, control circuit 7 controls to open electric heater and blower fan 5, electric heater is responsible for heating the air in cabinet 1, avoid moisture condensation, blower fan 5 for being discharged in time by moisture, thus can ensure cabinet inner drying, avoids electric elements to make moist.Blower fan respectively installs one in both sides, and ensure that air-flow is unobstructed, make dehumidifier better effects if, electric heater is respectively arranging a set of up and down, can heat the air of top and bottom respectively, ensures heating effect; Electric heater adopts self-constant temperature well heater, can carry out automatic temperature-adjusting control, ensures heated at constant temperature.
