Description
Technical field
The present invention relates to a kind of dehydrating unit for ring main unit enclosure space, belong to the supporting technology field of electric power facility.
Background technology
Ring main unit is in actual moving process, the impact of surrounding environment can be subject to, especially the impact of air humidity, because air humidity is large, easily cause equipment surface to condense moisture, cause mould to grow quickening, make electrical insulation strength by low, corrosion of metals is accelerated to cause contact-making surface to be oxidized, and contact resistance increases; Therefore air humidity forms very large threat to the safe and stable operation of ring main unit, not only has influence on user and produces, also considerably increase the workload of operation maintenance simultaneously.Traditional dehumanization method is: the air that temperature is higher can hold more moisture, adds hot-air and just can prevent condensation.But the maximum shortcoming of the method is that moisture is still at device interior, and effect is bad.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of structure to form rationally, volume is little, and stability is high, without the need to cold-producing medium and drier, can obtain the dehydrating unit for ring main unit enclosure space of better effect on moisture extraction.
The object of the invention is to have come by following technical solution, a kind of dehydrating unit for ring main unit enclosure space, it comprises one and is arranged on temperature sensor in electric equipment, and this temperature sensor connects a controller, and this controller is connected with semiconductor refrigerator; Described semiconductor cooler is arranged in the enclosure space of ring main unit, and the front and back of described semiconductor cooler is at least provided with the fan that faces condenser in semiconductor cooler.
Described condenser arrangement has one for condensation and removes the cold plate of steam, and the limit wall of the front and back ring main unit of condenser offers air inlet and air outlet; The enclosure space bottom of described ring main unit is provided with condensate water discharging mechanism.
Be connected to a liquid collecting funnel below described cold plate, and liquid collecting funnel faces bottom condensate water discharging ditch or rhone, and the condensate water discharging mechanism described in forming.
The present invention has structure composition rationally, and volume is little, and stability is high, without the need to cold-producing medium and drier, can obtain the features such as better effect on moisture extraction.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of semiconductor cooler of the present invention.
Fig. 2 is the structural representation of dehydrating unit of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1,2, a kind of dehydrating unit for ring main unit enclosure space of the present invention, it comprises one and is arranged on temperature sensor 1 in electric equipment, this temperature sensor 1 connects a controller 2, this controller is connected with semiconductor refrigerator 3, for the refrigeration control of semiconductor cooler 3; Described semiconductor cooler 3 is arranged in the enclosure space of ring main unit 4, and the front and back of described semiconductor cooler 3 is at least provided with the fan 6 that faces condenser 5 in semiconductor cooler.
Described condenser 5 is configured with one for condensation and removes the cold plate of steam, the limit wall of the front and back ring main unit of condenser 5 offers air inlet 7 and air outlet 8; The enclosure space bottom of described ring main unit is provided with condensate water discharging mechanism 9.
The preferred embodiment of the invention is: below described cold plate, be connected to a liquid collecting funnel, and liquid collecting funnel faces bottom condensate water discharging ditch or rhone, and the condensate water discharging mechanism 9 described in forming.
It is be based upon on the basis of thermoelectric cooling that the semiconductor cooling that the present invention adopts doubts dehydrating unit, is cooled to by the hydrone in air dew point temperature to be issued to the object of dehumidifying.Compared to traditional dehumidifying technology, it has, and volume is little, stability is high, without the need to cold-producing medium and drier, eco-friendly feature.
Embodiment: shown in Fig. 1, it is be based upon on thermoelectric cooling basis that semiconductor cooling doubts dehumidifying, mainly Seebeck effect and Peltier effect.It is the phenomenon of electric energy that Seebeck effect to refer to thermal energy by N-type and P type two kinds of semiconductors.Peltier effect is then in contrast, is the phenomenon of heat energy by electric energy conversion.Cold doubtful dehumidifying is that direct current is realized by one or more pairs of N type and P type semiconductor.Fig. 1 is then the right refrigeration model of single thermoelectricity.In refrigeration mode, direct current flows to P type semiconductor from N type semiconductor.The temperature of thermoelectricity centering cold junction reduces, and absorbs heat from environment.When electronics flows to the high-energy tail of N type semiconductor by interconnective conductor from the low energy end of P type semiconductor time, just can absorb heat from environment.Then heat transfers to other one end by electrical conductivity, the release heat when electronics turns back to the low energy end of P type conductor.Multiple thermoelectricity, to linking together, just forms thermoelectric device.
Semiconductor cooling is doubted dehydrating unit and in seal cavity, is formed air-flow by fan, air water molecule is condensate in condenser condenses plate periphery, cold plate air themperature is down to zero point, the hydrone condensation in air, collect through liquid collecting funnel and drain into seal cavity outside, continual work like this, thus reach reduction inside electric appliance space humidity object.Specific embodiments of the invention can adopt:
1), humidity collection controls main part: it is by humidity sensor, gathers inside electric appliance humidity height thus the start and stop of control semiconductor cooling condenser work.
2), semiconductor cooling doubts device main part: it is the core main part of dehydrating unit, produces cold-thermal effect after work; Hot junction under fan effect acceleration equipment inner air flowing, cold junction will flow humidity chamber gas rapid condensation formation water droplet, reach the object that thoroughly dehumidifies.
3), solidifying water draining main part: condensed water droplet is assembled through the quick device for transferring of pipeline inner, thoroughly eliminate the hydrone in inside electric appliance air.
4), working power: control main part to humidity collection, semiconductor cooling doubts device main part, fan etc. provides working power.
