Description
Technical field
The present invention relates to a kind of semiconductor dehumidifying devices for switchgear cool-down dehumidification.
Background technology
In summer especially in plum rain season, wet weather, high fever, the equipment such as inside switch cabinet breaker longtime running can produce
Heat amount, it is final so that the high-low pressure cabinet in electric substation generates condensation.Switchgear degree of protection is higher, heat dissipation ventilation condition compared with
Difference, it is very good and form condensation due to sealing, and be attached to insulating surface and make dielectric accelerated deterioration, cause circuit breaker trip or
Electrical equipment damages.The operation in several years of switchgear linked network, equipment is discharged, and heating problem is very prominent, and a big chunk reason is exactly
Switchgear dehumidifying and cooling effect is not all right.Switchgear is not reached requirement with cable duct closure precision or long-play, inevitable
Moisture is caused to enter from fine gap.If condensation is more serious, it may occur that ionization phenomena, while ozone is generated, to influence
The normal operation of switchgear, or even cause the generation of accident.Therefore carrying out timely cool-down dehumidification to switchgear seems very
It is necessary.
Invention content
It is high sensitivity, good reliability, safe for switching the purpose of the present invention is to provide a kind of reasonable for structure
The semiconductor dehumidifying device of cabinet cool-down dehumidification.
Technical solution of the invention is：
A kind of semiconductor dehumidifying device for switchgear cool-down dehumidification, it is characterized in that：Including switchgear and dehumidification device；
The switchgear includes switch gear room, busbar storehouse, cable bin；The dehumidification device include dewatering type semiconductor dehumidifier, exhaust fan,
Wind-collecting cover and PVC pipeline；Exhaust fan is set below dewatering type semiconductor dehumidifier, and wind-collecting cover, collection is arranged in exhaust fan air draft side
Fan housing with and switchgear in the PVC pipeline that communicates of switch gear room, busbar storehouse, cable bin connect；
For absorbing extraneous air and being processed as cold dry air, the exhaust fan is used for the dewatering type semiconductor dehumidifier
It sucks a small amount of extraneous air to change the cold dry air for flowing through collection wind partition board and be mixed with, the wind-collecting cover and PVC pipeline are used for
Transmit cold dry air.
Dewatering type semiconductor dehumidifier is used to the air outside switchgear carrying out cool-down dehumidification, reaches switchgear and transports safely
Capable requirement；Exhaust fan is used to collect cold wind toward wind-collecting cover direction；Wind-collecting cover is then to be collected the cold air of preparation；PVC
Pipeline is then that cold air is transported in cable bin, busbar storehouse and the switch gear room of switchgear, carries out cool-down dehumidification to it, ensures out
The component closed in cabinet is safely and steadily run.
Dewatering type semiconductor dehumidifier, exhaust fan, wind-collecting cover and PVC pipeline may be implemented continual to be switchgear
Dry cold air is inputted, the temperature and humidity in switchgear is reduced, ensures that switchgear runs under the environment of safety
Semiconductor dehumidifier carries out Temperature and Humidity to the air outside switchgear, when the humiture satisfaction of extraneous air is wanted
It asks, directly initiates exhaust fan, dry cold wind is passed through switchgear；When aerial temperature and humidity is unqualified, dewatering type semiconductor removes
Wet device then carries out cool-down dehumidification to air, realizes aqueous vapor separation, when the aerial temperature and humidity after cool-down dehumidification is met the requirements, then opens
Exhaust fan is opened, dry cold air is transported to by wind-collecting cover and PVC pipeline in switchgear, when the humiture of switchgear reaches
When the requirement of safe operation, dehumidifier, exhaust fan are out of service；With the operational heat of component in switchgear, work as switchgear
Interior Temperature Humidity Sensor detects that temperature or humidity not up to require, then exhaust fan works on, until to the temperature in switchgear
Humidity meets the requirements.
Traditional switch cabinet bus storehouse space is small, is not suitable for increasing dehumidification device in inside, the present invention is removed in exterior design
Dry cold air is transported in busbar storehouse from the pressure relief vent of switchgear by PVC pipeline, ensure that equipment safety by wet device
Stable operation.
In the present invention, the drying cold air prepared is transported to switch gear room, cable bin, busbar storehouse by PVC three-way pipes, than
Traditional dehumidifying is faster, and effect on moisture extraction is apparent rapidly, more cost-effective.
Dry cold air is passed through in switchgear by the present invention by dewatering type semiconductor dehumidifier, realization aqueous vapor separation, can
Thoroughly solve the condensation problem in switchgear.After the cold air being passed through is heated, more steam can be accommodated.As drying is cold
Air is constantly passed through, and hot humid air is constantly discharged, and dilution may finally realize steam in switchgear thoroughly
Discharge.
The present invention realizes that aqueous vapor separation, the water of discharge can pass through fixed runner by dewatering type semiconductor dehumidifier
Outdoor is recycled or be discharged, the time condensation of conventional dehumidification steam is avoided.
