Description
Technical field
The utility model belongs to power system device technical field, and in particular to a kind of anti-condensation system of switch cubicle.
Background technology
During the use of the electrical equipments such as switch cubicle, when humidity is larger in air, it is relatively low that vapor runs into temperature
Electrical equipment when can be easily created the globule, that is, so-called condensation.The surface that the globule is attached to insulating materials can drop
The resistance of low insulation material, and then the insulating properties of electrical equipment are reduced, proximity switch tripping operation even damage electrical equipment, not only
The workload of maintainer is increased, the safe and reliable operation of system where also affecting electrical equipment.Therefore, it is necessary to electricity
Gas equipment is dehumidified.
The air of certain temperature has its corresponding saturated steam content (now relative humidity is 100%), and temperature is got over
Height, its corresponding saturated steam content is bigger, the saturated steam under water vapor in air content levels off to Current Temperatures
During content, for temperature once reducing, water vapor in air content exceedes saturated steam content under Current Temperatures, and vapor will be
The relatively low equipment inner wall surface of temperature separates out, and forms condensation.Therefore, the formation of condensation must have two conditions：First, air has
Higher relative humidity；Second, the device temperature that condensation occurs is consistently lower than its environment temperature.
In the prior art, the means of common dehumidifying condensation proof often have certain limitation, not blanket
Selection.
For example dehumidified using heater, i.e., by heater plate, make to condense in the globule evaporation on electrical equipment.
But when the globule after evaporation runs into the relatively low electrical equipment of temperature again, again may regelation, individually by heating prevent
The effect of condensation is unsatisfactory.
Such as forced ventilation/exhausting method again, it is that extractor fan, top-side installation exhaust are installed in box bottom of cabinet bulk
Fan, accelerate the circulation of cabinet inner air so that cabinet inner air has been at unsaturated state, destroys condensation and forms bar
Part.Shortcoming is that this method needs to configure the equipment such as fan, can produce noise during operation, while part cabinet inner space is limited,
Installation difficulty, it is more to lack power supply or power supply capacity deficiency inside part ring main unit and feeder pillar, therefore this programme is more
Suitable for the anti-condensation processing of box type transformer.
Electricity removes wet method for another example, and its general principle is to produce a low temperature point by semiconductor refrigerating technology, by air
Steam condensation on the aspect, water droplet is along condensate tank(trap) and pipeline discharge cabinet, so as to play the effect on moisture extraction to switch cubicle.Half
Conductor type line dehydrating unit advantage is small volume, is easily installed, (in 15W or so) low in energy consumption, and open air is it is contemplated that use solar energy
Battery powered, vibration, noise are not produced during work, while there are good power savings；Shortcoming be it is expensive, cabinet humidity compared with
Effect on moisture extraction is limited when big.
Also Desicdant method, i.e., absorb the moisture in cabinet using drier, avoid the formation of condensation, and this aspect is simple
It is easy-to-use, but drier is easily saturated, if do not changed timely, its anti-condensation effect can significantly reduce.
Utility model content
For the deficiency in the presence of prior art, the utility model, which provides one kind, can realize automatic dehumidifying, dehumidifying
Efficiency high, energy consumption, the anti-condensation system of switch cubicle of drier alarm can be reduced.
A kind of anti-condensation system of switch cubicle, including switch cabinet body, the cabinet is interior to be provided with processing unit, humidity sensor
Device, communication module, power module, in addition to electronic weighing device and the drier that is placed on electronic weighing device, it is described
Power module provides power supply for system；
The processing unit electrically connects with humidity sensor, communication module, power module and electronic weighing device respectively.
As further optimization, in addition to temperature sensor and heater, the temperature sensor and heater respectively with
The processing unit electrical connection.
As further optimization, in addition to semiconductor cooler, condensate tank(trap) is provided with below the semiconductor cooler, it is described
Condensate tank(trap) exit is provided with drainpipe, outside the drainage pipe end pass-out cabinet；The semiconductor cooler and the processing are single
Member electrical connection.
As further optimization, in addition to the ventilation unit of cabinet side wall is arranged on, the ventilation unit and the processing
Unit electrically connects；The ventilation unit is divided into scavenger fan and extractor fan, and the scavenger fan and extractor fan are set respectively
In the two lateral walls of the cabinet.
Compared to prior art, the utility model has the advantages that：
1st, a variety of dehumidifying condensation proof devices are controlled by using processing unit, make full use of dehumidifying means, can be maximum
Energy consumption is reduced to limit anti-condensation while, improves dehumidification rate；
2nd, by using electronic weighing device come judge drier whether saturation, by communication module send out alarm letter
Breath, drier can be changed in time, anti-condensation effect is more stable；
3rd, coordinated by temperature sensor and heater to realize that the intelligence of heater opens and closes, do not influenceing effect on moisture extraction
In the case of reduce energy consumption as far as possible；
4th, coordinated by humidity sensor and semiconductor cooler, effectively can be coagulated vapor in non-heater
Tie and discharge outside switch cubicle, anti-condensation effect is good.
