Abstract
The invention discloses a power cabinet dehumidifying device comprising humidity detection units, a power circulation unit, a drying unit, a circulation pipeline and control switches. The power circulation unit is a closed circulation system, the outlet of the power circulation unit is connected with a main circulation pipeline and then connected with power cabinets through branch pipelines, the outlets of the power cabinets are connected with the main circulation pipeline through branch pipelines and then communicated with the drying unit, the drying unit is connected to the inlet of the power circulation unit, and the control switches are respectively arranged on the branch pipelines at the inlets of the power cabinets. The humidity detection units are installed in the power cabinets, are linked with a starting switch of the power circulation unit, and are linked with the control switches of the branch pipelines. By utilizing the power cabinet dehumidifying device, multiple power cabinets can be connected simultaneously, and the air humidity in the power cabinets can be effectively reduced without increasing the temperature in the power cabinets. Moreover, the power cabinet dehumidifying device has the advantages of low power, energy conservation and environmental protection.
Description
Technical field
The present invention relates to electric power system electric power cabinet, particularly relate to a kind of electric power cabinet dehydrating unit.
Background technology
Electric power cabinet is the critical facility in electric power system, and its safe operation concerns the normal operation of each relevant device, is therefore also paid much attention to inspection its protection.If electric power cabinet runs in wet condition, safely hidden danger is brought to it, when temperature is more than 30 DEG C, when relative air humidity is more than 80%, then dew condensation phenomenon can be caused, condensation can cause power equipment binding post burn into reduce insulation property and cause short circuit, causes unnecessary power outage and loss.
Conventional solution one is electric power cabinet mounting heater, ensure air oxygen detrition in cabinet, although cabinet humidity reduces like this, temperature in cabinet can be made to raise, this is to the instrument in cabinet, components and parts, and the reliability of wire, working of plastics and useful life all affect larger; Scheme two installs dehumidifier additional in the room installing case equipment, can ensure that indoor relative humidity controls below 85% like this, make the humidity in cabinet meet equipment service requirement.But because the solid space installing case equipment room is larger, so just need the dehumidifier that installation power is larger, the noise produced when so not only wasting electric energy but also dehumidifier work is also comparatively large, and room residing for some electrical power cabinet be not suitable for installing dehumidifier.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of electric power cabinet dehydrating unit, can connect multiple electric power cabinet simultaneously, guarantee electric power cabinet in running environment humidity lower while, do not make electric power cabinet temperature relatively raise, and plant capacity is little, energy-conserving and environment-protective.
To achieve these goals, technical scheme of the present invention is:
A kind of electric power cabinet dehydrating unit, comprise humidity detection unit, power cycle unit, drying unit and the composition such as circulating line and switch control rule thereof, described power cycle unit is closed-cycle system, its outlet connects major cycle pipeline, connect each electric power cabinet by branch pipe(tube) again, after each electric power cabinet outlet connects major cycle pipeline by branch pipe(tube), pass into drying unit, drying unit receives power cycle unit entrance again, and described each electric power cabinet entrance branch pipe(tube) is respectively equipped with control switch; Described humidity detection unit is arranged in each electric power cabinet, is associated with the starting switch of power cycle unit, and is associated with described branch pipe(tube) control switch.Electric power cabinet top is located at by described electric power cabinet entrance branch pipe(tube), and electric power cabinet bottom is located in described electric power cabinet outlet stool road.The exit of described electric power cabinet entrance branch pipe(tube) is provided with threeway, and its opening is towards electric power cabinet sidewall.
Further, described drying unit is sealed transparent casing, is provided with drier in it.
The invention has the beneficial effects as follows: this device can connect multiple electric power cabinet simultaneously, effectively can reduce the air humidity in electric power cabinet, do not cause electric power cabinet temperature to raise, this rating of set is less simultaneously, energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with specific embodiment, the present invention is described further.
As shown in Figure 1, a kind of electric power cabinet dehydrating unit, comprise humidity detection unit 1, power cycle unit 2, drying unit 3 and the composition such as circulating line 4 and control switch 5 thereof, described power cycle unit 2 is closed-cycle system, its outlet connects major cycle pipeline 41, each electric power cabinet 6 is connected again by branch pipe(tube) 42, after each electric power cabinet outlet connects major cycle pipeline 44 by branch pipe(tube) 43, pass into drying unit 3, drying unit receives power cycle unit 2 entrance again, and described each electric power cabinet entrance branch pipe(tube) is respectively equipped with control switch 5; Described humidity detection unit 1 is arranged in each electric power cabinet, is associated with the starting switch of power cycle unit, and is associated with described branch pipe(tube) control switch 5.Electric power cabinet top is located at by described electric power cabinet entrance branch pipe(tube) 42, and electric power cabinet bottom is located in described electric power cabinet outlet stool road 43.The exit of described electric power cabinet entrance branch pipe(tube) 42 is provided with threeway, and its opening is towards electric power cabinet sidewall.
Further, described drying unit 3 is sealed transparent casing, is provided with drier in it.
Embodiment: described power cycle unit is located near electric power cabinet, be connected with each electric power cabinet respectively with a circulating line by major cycle pipeline, moisture detector is provided with in each electric power cabinet, when humidity reaches set point, start power cycle unit, open branch pipe(tube) switch, in electric power cabinet, air enters drying unit by circulating line simultaneously, in air, the dried unit of moisture absorbed, then is circulated by power cycle unit.Outside the starting switch of described moisture detector association power cycle unit, associate corresponding branch pipe(tube) switch respectively, if this electric power cabinet humidity exceeds standard, then this electric power cabinet is dehumidified; Or also moisture detector can be located at electric power cabinet set place, associate each branch pipe(tube) switch simultaneously, when electric power cabinet humidity over limit, can dehumidify to all electric power cabinets simultaneously.Described drying unit is sealed transparent casing, and convenient its internal desiccant state of observation, can change during inefficacy in time.
Technical scheme of the present invention is not limited to the restriction of above-mentioned specific embodiment, the technology distortion that every technical scheme according to the present invention is made, and all falls within protection scope of the present invention.
