Description
Technical field
It the utility model is related to the dehydrating unit of distribution box, specially distribution box automatic dehumidification device.
Background technology
It is located in the distribution box or controller switching equipment in Southern Mountain Areas of China humidity location, such as the light distribution box in major long tunnel, often
There is distribution in-box electric appliance（Son）Element causes the problems such as equipment fault through moisture, such as the corrosion of relay element, failure row
Complexity is looked into, maintenance of equipment is difficult, takes time and effort.For this present situation, currently without good solution.
The content of the invention
The utility model solves the electrical equipment in distribution box（Son）The problem of easily being broken down under element wet environment, there is provided one
Kind distribution box automatic dehumidification device.
The utility model adopts the following technical scheme that realization：Distribution box automatic dehumidification device, including high-voltage cast-aluminum system
Into and casing with door, casing both sides be respectively provided with two and open porose fixed auricle thereon, the bottom of cabinet door, which is provided with, to be dissipated
Hot hole；Box house is provided with heating and dehumidification control circuit, and control circuit is switched by humidity inductive, heating wire and hand switch concatenation
Form, the both ends outlet box of control circuit is external.In use, casing is bolted in distribution box by fixed auricle,
Two ends for leading to the control circuit outside casing are connected at the power supply reserved opening in distribution box, after inspection is errorless, by hand switch
Closure connects circuit, and automatic dehumidifying equipment is started working.When the ambient humidity height that humidity inductive inductive switching arrives is prior in the inner
When setting or the higher limit set, humidity inductive switch closure, heating wire heating power, heat gives out from the heat emission hole of casing
Go, heating and dehumidification is carried out to distribution box cavity.It is previously set or sets in the inner when the ambient humidity of humidity inductive inductive switching is low
During the lower limit put, humidity inductive switches off, and control circuit disconnects, and heating wire is stopped.
Distribution box automatic dehumidification device electrical structure described in the utility model is simple, easy to operate.It is cost-effective：This is matched somebody with somebody
Electronic box automatic dehumidification device material therefor, part can purchase on the market, cheap, can be effectively accomplished after installation
Effect on moisture extraction, expensive controller switching equipment is not damaged because by cargo sweat, while also greatly save personnel and investigate event
Barrier, the time of handling failure.It is safe for operation：The distribution box automatic dehumidification device take into account maintenance personal's safety, and there is provided one
Individual external hand switch, after needing to unpack, it will need to only switch off.The other equipment have also contemplated that asking for air draft
Topic, the radiating hole of fine mesh is devised on casing, can prevent the small worm of outside from crawling into radiating hole and causing damage.
Brief description of the drawings
Fig. 1 is the external structure schematic diagram of the utility model casing；
Fig. 2 is the schematic diagram of heating and dehumidification control circuit.
In figure：1- casings, 2- fix auricle, 3- heat emission holes, 4- mounting holes, 5- operation indicator holes.
Embodiment
Distribution box automatic dehumidification device, including made of high-voltage cast-aluminum and the casing 1 of door is carried, casing both sides are respectively provided with two
Individual to open porose fixed auricle 2 thereon, the bottom of cabinet door is provided with heat emission hole 3；Box house is provided with heating and dehumidification control circuit,
Control circuit switchs K1, heating wire L and hand switch K2 concatenation by humidity inductive and formed, and casing 1 is drawn at the both ends of control circuit
Outside.During specific making, the top of cabinet door is provided with mounting hole 4, and described hand switch K2 is fixed in the mounting hole, with convenient
Operate and safe for operation.Heating wire L both ends are parallel with by the branch road of run indicator D and resistance R concatenations, meanwhile, cabinet door
Top is provided with operation indicator hole 5, and described run indicator D is fixed in the operation indicator hole, to facilitate the fortune of observation device
Row situation.Circular hollow out is made in described heat emission hole 3, prevents small worm from climbing into.There is humidity inductive switch K1 following parameter to refer to
Mark：Induction range：20-80% RH, environment temperature：- 9.9-99.9 DEG C, precision：± 4.5rh, response time：≤ 4S, differentiate
Rate：0.1% relative humidity.Thermal switch K1 can be at least used by the production of Sen Sideke Science and Technology Ltd.s of Shenzhen, type
Number be SHT31 product.
