Description
Technical field
The present invention relates to the technical field of air ambient in control electric box, in particular to a kind of control enclosed type electric gas tank
Interior temperature, the system of humidity.
Background technology
In power transmission and distribution facility, communications facility, there is substantial amounts of equipment to need to be installed in relatively closed case, in cabinet,
To meet the operation demand of its insulation, isolation and protection.And these casees, cabinet have most to be installed in open air, bar is run
Part rather harsh.For a long time, people this kind of case, cabinet are generally regarded as simple a container or auxiliary device and seldom to
Give enough attention, its internal micro environment control is even more a blank ignored for a long time so that the design of these bin bodies and
Structure is excessively simple；Protective capacities and the scarce capacity for resisting inside and outside portion's environment influence, temperature control dehumidifying measure is unreasonable, causes
Thermal environment, electrical environment inside these bin bodies is bad, overheat, condensation, contamination situations such as protrude, trigger various defects with it is different
Often.Influence electric, communication equipment performance and operational reliability.
Mainly there is the following aspects for the Improving Measurements of electric, communication equipment box cabinet internal environment at present：
The consideration entered based on dust-proof and protection against insect, takes bin body limited seal approach.Inside this kind of bin body
Due to lacking the concurrent condition needed for radiating, static air can form " detention layer " in equipment or element surface, and this is " stagnant
Fluid layer " can produce totally unfavorable influence equivalent to thermal insulation layer to the radiating of equipment or element.This is also some indoor arrangements
Case, cabinet, screen in the case that air-conditioning falls too low room temperature still or overheat major reason.
Secondly because sealing is not strict mostly for bin body, expanding with heat and contract with cold for inner air can cause breathing phenomenon, especially
It is that ash dirt is easily disorderly entered by the slight gap of random distribution with filtered air in the case of the hole that breathes no more
Cartonning cabinet simultaneously precipitates at each position of casing, and cabinet design is without self detergent power, therefore memory box is in dust stratification, product
Dirty bad condition；Contain a large amount of metal micro particles, metal oxide and all kinds of acidic materials in grey dirt.It is likely to become in case
Electric component corrosion, insulation breakdown, the important substance condition for even triggering pollution flashover failure.
Ventilation and heat measure based on free convection and forced convection.The bin body of thermal source for partial interior be present, it is existing
Some measures are to set disengaging air holes in some face of bin body or install small, mini fan to be aerated.But due to bin
Body internal unit, the randomness and the uncertainty in gas channel and space of part installation, can not the necessary water conservancy diversion of design and installation
Measure, this kind of ventilation and heat mode is set to be difficult to reach desired effect because a large amount of dead angles or unordered turbulent flow be present.But also can be because
Dust largely enters to enter with humid air triggers the problem of more serious.
Electric heater is used based on dehumidification.Often throw or interruption is put into（Temperature control or wet control）Electric heater, it is current electricity
The generally dehumidifying of use, the damp measure of drop of gas equipment bin.Its working mechanism is by heating air, improving the wet volume capacity of air
（Accommodate and absorb the ability of vapor）, so as to reduce relative humidity.But in existing all kinds of bin bodies, heater is answered
Some effects run counter to desire are produced with very random.
It is that casing is in closed state first, inside does not have a cross-ventilation, adds in casing at air relative to inactive state
Hot device is mainly heated by radiating to air, and static air is a kind of heat insulator, and its effect can block heat transfer,
Therefore in this case, heating of the heater to air is local, uneven and incomplete.Box house is caused to be formed
Larger thermograde and cold and hot interface, exacerbate dew condensation phenomenon on the contrary.
Next to that lacking leading off containing humid air, discharge channel inside bin body, there is cable duct bottom continuously again
Supplement aqueous vapor.Then, the air of heating absorbs more aqueous vapors, and is detained in casing, and the temperature of heating is higher, absorbs and stagnant
The steam stayed is more, once the in a slight decrease just rapid saturation of air themperature in cabinet, forms one of essential condition of condensation.
3rd, due to the use of heater so that bin body internal temperature is often higher than outside casing, produces significant temperature
Degree is poor, and forms cold surface in cabinet wall, turns into another essential condition of condensation, then, substantial amounts of, lasting condensation mistake
Journey is just unavoidable.Under serious conditions, even it also occur that local seeping phenomenon in casing body.Once dust stratification in bin body,
Contamination and lasting two kinds of effects of condensation are superimposed, will greatly promote generation pollution flashover, the probability of insulation fault in case, will be serious
Threaten the safe operation of electrical equipment.
As can be seen here, the unreasonable use of heater, its effect are almost what is lost more than gain.
4th, the measure for installing packaged air-conditioner inside and outside equipment box cabinet.Because its input is high, efficiency is low, energy consumption
Greatly, cost effectiveness difference and extensively denounced.
From the above analysis, the bad basic reason of radiating is a lack of convection current in electric component box cabinet or convection current is uneven
Weighing apparatus, the basic reason of condensation are that internal-external temperature difference and internal temperature gradient are excessive, cold surface are formed in cold and hot interface.Therefore must
It must explore, seek a kind of new draft type and convection current form.

Embodiment
In order to more clearly describe the technology contents of the present invention, further retouched with reference to Fig. 1 to Fig. 6
State.
The principle of the present invention is illustrated first.The application environment of the present invention is small micro- space of the grade closing of electric box 1,
Turn into a kind of brand-new using displacement ventilation: Principles as the weak air flow ventilating system of small momentum instructed, after Import computer intelligent control
Microenvironment intelligent control technology is good using Thermal plume the purpose is to form the free convection form of Thermal plume in bin body
Diffusivity and diffuse characteristic, eliminate the dead corner in bin body, avoid being partially formed high-temperature region, improve flow field and thermal field point
Cloth, so as to destroy the condition to form condensation from source.
The electric box 1 that the present invention is regulated and controled is as shown in figure 1, be a kind of enclosed electric box 1, on the top of electric box 1
It is provided with exhaust outlet 11；Micro environment control device 2 is arranged on the top of electric box 1, is sent by wind-guiding air outlet 25 into electric box 1
Wind；Air supply direction is to blow downwards；The air flow rate for being sent into described micro environment control device 2 is controlled by intelligent control unit 3, intelligence
The control signal of energy control unit 3 derives from sensor.
The operation logic of the present invention is described further with reference to Fig. 2.When micro environment control device 2 is blown downwards,
During the air-flow of feeding reaches the bottom of electric box 1, in electric box in the presence of each interlayer temperature difference and micro-pressure-difference, air-supply way
Middle fraction produces laterally shunting.The air dissipation of parts transversely, the diverse location in electric box 1 are produced when blowing downwards
The air capacity of horizontal loss and the air being sent into are relevant with the temperature difference in electric box 1, during air transverse direction loss, introduce
Air more flow to the region that temperature is higher in electric box 1, so as to reduce the high-temperature area in electric box 1, balanced electrical
The air themperature in each region in case 1.
After the air velocity blown downwards gradually reduces, flow velocity is concurrently given birth to close to zero and is horizontally diverted when reaching bottom,
Case bottom of cabinet bulk forms the bottom air layer of geo-stationary.Typically there is the electrical equipment that can be generated heat in regulator cubicle, due to these
The fuel factor of heater, air's density variation is produced in its space, forming space Thermal stratification under buoyancy lift effect shows
As that is, because the inside fuel factor of electric box 1 produces Thermal plume, forming air microenvironment in the case that lower floor's temperature is low, upper strata temperature is high.
The process that above-mentioned Thermal plume forms temperature ladder layer in electric box 1 constantly occurs in electric box 1, due to electric box 1
It is interior slowly to reach thermal balance and hot-air is lighter, in spite of air is introduced, the process is all being carried out always.With electric box
In 1 unlike the air stratification of self-assembling formation, temperature phase can be formed in bottom behind the bottom of the air arrival electric box 1 of introducing
To relatively low air pond, the temperature in the air pond can have the larger temperature difference with upper layer of air, so as to carry out thermally equilibrated mistake
Cheng Zhong, the bulk temperature in electric box 1 can be reduced.When blower fan 22 introduces air, layer of air is gone up from exhaust outlet in electric box 1
11 discharges.Due to temperature ladder layer in electric box 1 be present, the higher air of temperature is in upper strata, it is therefore desirable to preferentially by top temperature
The higher air of degree is discharged out of electric box 1.The free convection thermal current of rising is the sky of Thermal plume exclusion space upper area
Gas simultaneously overflows closing space by top exhaust outlet 11, and the air of discharge is continuously supplemented from lower air layer, from
And form the displacement of air.
Embodiment one as shown in Figure 1, Figure 3, in order to realize the principle of humiture in above-mentioned regulation and control electric box 1, it is necessary to to
The position of air-supply in electric box 1, direction, the time, air mass flow, humiture etc. is controlled in electric box 1.Microenvironment can be used

Top, micro environment control device 2 includes shell 21, blower fan 22, filter 23；There is air-vent 24 on shell 21；Air-vent 24
Filter 23 is housed between air inlet 221.Shell 21 plays a part of loading each part, while can be used as drawing
The passage of wind uses；Blower fan 22 is used for providing power for air inducing；The air outlet of blower fan 22 is wind-guiding air outlet 25, described wind-guiding
Air outlet is exactly the part for guiding air-out direction, and wind-guiding air outlet 25 can be a part for blower fan, in the air-out of blower fan
When mouth does not have wind-guiding function, the air outlet with air ducting can also be installed additional on blower fan.Can be in air-vent 24 and blower fan 22
Between install filter 23 additional, prevent debris, dust, insect etc. of outside from entering.Blower fan 22 introduces air from air-vent 24,
After the filtering of filter 23, enter after the feeding of air inlet 222 from wind-guiding air outlet 25 in electric box 1.
The type of blower fan 22 used in the present invention is needed according to the different structure of electric box 1 and micro environment control device 2
Position is selected.For the type of blower fan 22, air-out direction is selected to be easy to the blower fan 22 of control preferable, such as centrifugal wind
Machine, horizontal type blower fan etc..As in Fig. 1, horizontal type blower fan is used, is because micro environment control device using the reason for horizontal type blower fan
2 are arranged on lateral wall, install horizontal type blower fan in this case and are relatively adapted to, horizontal because the air outlet of horizontal type blower fan is strip
The air-out section of formula blower fan is more easy to be bonded with the inside of electric box 1, and air curtain can be formed on air-out direction, i.e. the direction of air curtain is
It is close to the inwall of electric box 1.Under such configuration, using the adsorption effect of the inwall of electric box 1, enable air-flow with smaller flow velocity i.e.
The bottom of electric box 1 can be sent to.And when micro environment control device 2 is arranged on other positions, as electric box 1 top when, can basis
The internal structure of electric box 1 selects the blower fan of the other structures such as centrifugal fan.
Illustrate the control mode of the present invention with reference to Fig. 4.Intelligent control unit 3 controls wind by the signal of sensor
Machine 22, including Temperature Humidity Sensor 42 outside Temperature Humidity Sensor 41 and case in case, Temperature Humidity Sensor 41 is used to detect electricity in case
Humiture in gas tank 1, the outer Temperature Humidity Sensor 42 of case are used for the humiture for detecting the gas for introducing electric box 1, for intelligence control
The control of unit 3 processed provides signal to control air-out flow.According to the difference of control mode, different blower fans also may be selected, if any
The blower fan of frequency conversion function and the blower fan of constant speed, intelligent control unit 3 can control frequency conversion fan to carry out air-out with different power, can
So that blower fan is in prolonged air-out state, need to set in intelligent control unit 3 in this case warm in different casees
The operation power of blower fan 22 corresponding to the numerical value of the outer Temperature Humidity Sensor 42 of humidity sensor 41, case；And constant speed blower fan 22 is then
Need intelligent control unit 3 that threshold value is set to Temperature Humidity Sensor 42 outside Temperature Humidity Sensor in case 41, case, when the number detected
Blower fan 22 is controlled to start when value reaches certain threshold value.
Illustrate return air window 27 with reference to Fig. 1 to Fig. 6 below, described return air window 27 is located on the inside of electric box and micro-
Between the inner chamber 28 of environment control unit, unlatching, closing and the unlatching of return air window 27 it is size-controlled in intelligent control single
Member 3.So-called inner chamber 28 is that interior space is wrapped in by shell 21.When return air window 27 is closed, the sky in electric box 1
Flow of air is mainly derived from from the air inlet of air-vent 24, is discharged air from exhaust outlet 11, i.e., is carried out and outside in electric box 1
Air exchange；And when return air window 27 is opened, will have from the air of air inlet entrance and be derived partly from electric box 1
Inside, the amount of the air inside electric box 1 depend on the size that return air window 27 is opened.I.e. when return air window 27 is opened
When, will produce the interior circulation of air in electric box 1 in the inside of electric box 1, electric box 1, the displacement of outside air will with it is electric
Internal air circulation is synchronously carried out in case 1.When using blower fan 22, it can be blown downwards along the side wall of electric box 1, and produce suitable
The downward air curtain of the side wall of electric box 1, when in electric box 1 air enter from return air window 27 produce in circulate when, air curtain will be
Electric box inner ring streams movable property life circulation, so as to eliminate the dead angle area in electric box.
When return air window 27 is used in combination with filter 23, due to being deposited in passage of the air-vent 24 into inner chamber 28
In filter 23, thus from air-vent 24 enter air-flow windage it is larger, and return air window 27 due to do not install it is any can
The device of windage can be increased, therefore what is circulated in electric box 1 in progress is not present windage, therefore when return air window 27 is opened
When, the interior meeting carried out of electric box 1 is internal air circulation, and only a small amount of air will can be introduced from air-vent 24.I.e. when filter 23
With return air window 27 simultaneously in the presence of, open return air window 27 when, electric box internal air circulation can be carried out.This kind of technical side
Case is applicable to reduce the situation that extraneous air flows into.The interference of external environment condition can be reduced, especially suitable for some environment
It is easier in the electric box 1 of the position of mutation.Such as Thunderstorm Weather, drastically cool many extreme weathers, to being placed on outdoor
Electric box 1 for belong to extraneous air humiture occur drastically change.
The application of return air window 27 is wider, and avoiding the humiture outside case to be mutated as described above causes to influence case
Interior, then the control signal of return air window 27 should derive from Temperature Humidity Sensor 41 in the outer Temperature Humidity Sensor 42 of case and case.Return air
27 mouthfuls of window can also have other applications, such as avoid forming the local excessive temperature difference in case, such as at summer due to possibility of being exposed to the sun
Cause the temperature at the top of electric box to be higher by much than lower floor, now open the humiture that return air window 27 is advantageous in case and balance,
Control the signal of return air window 27 humiture should pass in the electric box of Temperature Humidity Sensor 411 and second in the first electric box
Sensor 412, the temperature difference in case is generally placed at upper and lower part, therefore the quantity of Temperature Humidity Sensor is at least in electric box
Two, the position of at least one takes in the top of electric box, the position of at least one in the bottom of electric box, specific arrangement
Certainly in the position that electric box is laid and the shape of electric box.
Illustrate embodiment two below, in order to improve Environmental Control Effect in electric box 1 unlike embodiment one, install
Pneumatic sensor 43, described pneumatic sensor 43 is located at the bottom of electric box 1, on the air-out direction of blower fan 22, i.e. gas
What flow sensor 43 sensed is that the air-flow that blower fan 22 is blown out reaches electric box 1 close to speed during bottom.From air-vent 24 to electricity
The air-flow of the bottom of gas tank 1 conveying is, it is necessary to meet several conditions：First, speed can not be too fast, otherwise can cause to produce in electric box 1
Sinuous flow；2nd, a certain amount of horizontal loss must be produced during flowing downward, hence into each dead angle in electric box 1；
Flow velocity can not be too fast when the 3rd, reaching 1 bottom of electric box, reaches as small as possible during bottom.In order to meet conditions above, in embodiment
The middle computing interval for needing the height to air-vent 24, position, the air-out flow of blower fan 22 etc. to carry out precision has error unavoidably.Such as
Pneumatic sensor 43 can be added in the position of the bottom of electric box 1 close to bottom, then can preferably monitor the air-out flow of blower fan 22,
So as to be adjusted in real time.The signal of pneumatic sensor 43 is transported to intelligent control unit 3, and intelligent control unit 3 is according to air-flow
The numerical value of sensor 43, to control blower fan 22, such as the detection numerical value of pneumatic sensor 43 can be arranged into certain section,
During beyond the section, intelligent control unit 3 controls blower fan 22 to be adjusted air-out.
Illustrate embodiment three below, for convenience to dehumidifying in regulator cubicle, it is necessary to electric unlike embodiment one

The transverse direction of plate 251 refers to the direction of left and right in Figure 5, and horizontal wind deflector 251 can be used blinds, when blinds is swung, can produce
Horizontal pendulum wind, disturbed so as to reduce environment in the electric box of complexity to caused by air-supply.Increase horizontal wind deflector 251 to be applicable
In the case that the environment in electric box, structure are sufficiently complex, such as the special case in electric box：In terminal box, due to having
More cable arrangement, therefore dead angle is more in electric box, it is also difficult to it is straight by way of horizontal type blower fan is blown along madial wall
The bottom for sending airflow to electric box is connect, and horizontal wind deflector 251 can effectively reduce the interference of environment in electric box.
Using principle of the present invention and said structure, to progress in electric box 1 by taking the blower fan using constant speed as an example
It is described as follows exemplified by regulation and control：
Humiture in electric box 1 can be set, such as be set as that temperature, humidity are no more than an a reference value.Simultaneously
It is also required to be monitored the humiture of the air of introducing, such as the air themperature that setting introduces and the temperature gap in electric box 1
No more than certain temperature etc..The Threshold of Temperature And Humidity of setting above is used as blower fan 22, the entry condition of heater 26.
Temperature such as in electric box 1 is too high, when such as exceeding a reference value of setting；Or when the air and electric box that introduce
During excessive temperature differentials in 1, when reaching the degree of setting such as the temperature difference, then need to cooling in electric box 1.Wind-guiding air outlet 25 is sent
The air-flow entered can constantly be diffused before bottom is reached, and in the process, the air for being sent into electric box 1 enters electric box 1
Dead angle between interior each electric component.Meanwhile will form that bottom temp is low in electric box 1, the high air layer of upper temp,
Temperature highest air is discharged from the top of electric box 1 by the diffusion property of Thermal plume, characteristic is diffused due to Thermal plume, matched somebody with somebody
