Description
Technical field
The present invention relates to electrical cabinet internal environment guarantees, anti-condensation in particular to a kind of cascade cycle channel cool-down dehumidification
Electrical equipment safeguards system and method.
Background technology
Conventional electric power equipment indoors, installs power equipment outdoors mostly, is essentially all the gravity-flow ventilation of use
Mode radiates.Recently as wideling popularize for intelligent grid, intelligent substation, Intelligent control cabinet, convergence control cabinet and intelligence are eventually
The demand of the smart machines such as end is increasing, and the demand of stainless steel outdoor cabinet also constantly rises therewith.Due to matching in cabinet outdoors
The intelligent electronic devices such as detection, communication are set.The design of high-density integrated makes these smart machines produce huge heat
Release.Currently, the assembly ever greater concentration of microelectronics, outwork environment is also drastically to high temperature direction change.Electronics member device
Part temperature often increases 2 DEG C, and reliability will decline 10%, general electronic component, when temperature is more than the operating temperature 8 allowed
DEG C when, the service life will reduce by 50%.Therefore heat dissipation in time becomes an important factor for its service life of influence.It is not only high temperature, south
The continuous heat in side and rainy weather, even more form long-term hot and humid environment in cabinet.Traditional gravity-flow ventilation heat dissipation
Type outdoor cabinet cannot be satisfied the requirement that site environment uses.
More and more outdoor cabinets start to use heat exchanger, compressor or semiconductor cabinet air-conditioning equipment conduct now
Cooling profiles, but due to the environment of substation, do not cover very harsh, and stainless steel cabinet high temperature is frequent under direct sunlight
Reach 60 DEG C or more, once there is continuous rainfall, humidity is substantially 95% or more.These technological means of existing use, it is general
All over all presence can only freeze, temperature control is ineffective, function is simple, without operational safety safeguard measure, fluctuation of service, failure rate
It is high, to be not easy repair and maintenance etc. a series of applies drawback, high temperature problem that can not be inside effective control rack, humid control is even more
It does not know where to begin.How could realize and effective humiture improvement is carried out to outdoor cabinet, have become electric system now and ensure peace
The focal issue produced entirely.
The anti-accident technical measures file of emphasis in 2015 issued according to State Grid Corporation of China, for《State Grid Corporation of China
Prevent 16 measures (tentative) of substation's full cut-off》15.2.2 item requirement, Intelligent control cabinet should have temperature humidity regulatory function,
Minimum temperature should be maintained at+5 DEG C or more in cabinet, and maximum temperature is no more than cabinet external environment maximum temperature or 40 DEG C in cabinet, and humidity is answered
It is maintained at 90% or less.
Current existing outdoor electric cabinet Temperature and Humidity Control uses following several technologies：
1) outdoor electric cabinet fan radiating technology
The heat-sinking capability of outdoor electric cabinet fan radiating technology is limited, and the technology of grid requirements is not achieved in heat dissipation effect completely
Standard.Do not have anti-condensation dehumidifying effect, and without any management control function, ambient temperature and humidity in cabinet cannot be led yet
Dynamic control, wind turbine long time continuous working failure rate are high；
2) outdoor electric cabinet heat exchanger heat dissipation technology
Outdoor electric cabinet heat exchanger heat dissipation technology is mainly that certain heat release is carried out using cabinet internal-external heat exchanger mode,
The technical standard of grid requirements is not achieved in its heat dissipation effect completely under hot weather.Do not have anti-condensation dehumidifying effect, has
Certain managerial ability, but because being unable to reach target, equipment is also chronically at high load capacity working condition under harsh weather,
Wind turbine and control panel are easy to break down for a long time.Although the electronic components of opposite compressor and semiconductor temperature-control equipment
Less, failure rate is relatively low, but due to being installed using whole cabinet door, needs complicated dismounting and very long dimension once breaking down
The period is repaiied, for such a facility for needing high reliability guarantee of outdoor electric cabinet, operational support function is much not achieved
Operation of power networks, which ensures, to be required；
3) outdoor electric cabinet compressor air-conditioning Temperature and Humidity Control technology
Outdoor electric cabinet compressor air-conditioning Temperature and Humidity Control technology has stronger high temperature rejection ability, but its operating mode
For the higher anti-condensation dehumidification requirements of outdoor electric cabinet service requirement, processing capacity is a larger short slab.Because such
Type equipment does not have fine-grained management control ability, and single air channel structure cannot achieve efficient system circulation.For electrical outdoor
The high temperature of the electrical equipment of intensive arrangement still reaches to the guarantee target less than power grid reliability service with humidity rejection ability in gas holder,
Anti-condensation ability is more unreliable.And due to the excessive preponderance of volume, the scheme of cabinet door installation not only limits its effective system
Cold power bracket also limits the installation versatility that such equipment adapts to different size open air cabinet type.Compressor not only shakes
It is dynamic big, it is also easy to cause leakage of refrigerant, pole is not suitable for electrical cabinet requirement to two indexs yet.Setting in outdoor electric cabinet
Standby is all 24 hours annual uninterrupted reliability services of requirement, and humiture control device is to ensure that safe operation reliability must accord with
Close 7*24 hours matching running indexs.For heat exchanger scheme, such product uses more electromechanics and control element,
Outdoor harsh high temperature and humidity salt fog running environment adds long-term uninterrupted operation, and equipment failure rate residence will necessarily be very high.Pressure
Contracting cabinet dress air-conditioning similar-type products, which are substantially, fills using single machine door or pushes up dress scheme, once any device in single machine occurs
Failure, can all directly result in equipment and integrally paralyse and be unable to normal use.Single machine repair must whole cabinet door dismounting, must be outside producer
The live professional's operation of group, and the round-trip logistics transportation in strange land and repairing are organized, situation is serious to be possible to the round-trip several months, encounters
Equipment safety operation hidden danger is serious in cabinet when continuous harsh weather.Lack failure active communication function, also makes equipment fault long
Time cannot quickly administer, and the possible longtime running of the electrical equipment in cabinet is in hot and humid environment, so that can not be effective
Ensure the high reliability operation of equipment in outdoor electric cabinet；
4) outdoor electric cabinet semiconductor humiture control device
Existing outdoor electric cabinet semiconductor humiture control device, belongs to novel electron Temperature and Humidity Control equipment, no compression
Machine and refrigerant have active refrigeration dehumidification function, are very suitable for the safe handling requirement of outdoor electric cabinet.But it is because existing
Such equipment fails to realize efficient cooling piece heat dissipation, can not reduce the volume and weight of equipment.So once requiring installation symbol
The high power electronic humiture control equipment that operation of power networks requires is closed, it is equally a series of that compressor air-conditioning will be filled there is cabinet
Safe operation guaranteed reliability's problem.And existing type equipment also in default of fining Temperature and Humidity Control ability so that equipment
The big efficiency of operation energy consumption is low, and ageing equipment catastrophe failure rate is higher.The critical defect of single air duct local circulation structure design, makes this
Type device can not effectively inhibit the problem of condensation in cabinet completely；
5) outdoor electric cabinet semiconductor dehumidifying device
Outdoor electric cabinet semiconductor dehumidifying device has Active dehumidification function, and reduces equipment volume and weight, but
These modifications are all under the premise of sacrificing effective dehumidifying power.Its effect on moisture extraction is still limited by the heat radiation energy of cooling piece
Power, single air duct loop structure with inefficiency.In face of continuous rainy season or hot and humid environment, dehumidification efficiency reaches not substantially
To the safety requirements of operation of power networks, anti-condensation ability is even more to have no way of referring to.Although weight is little, complicated cabinet door mounting structure
Still repair demolition difficulty is caused, still there is very big hidden danger for outdoor electric cabinet safe operation reliability；
In addition, by furtheing investigate the space environment in outdoor electric cabinet, research finds that the main reason for condensation is formed is
Since electrical cabinet there are the cooling requirements of connection path and aeration structure, can not possibly be fully sealed in cabinet, air humidity is excessive.Because
Ambient humidity is bigger, and for dew point just closer to environment temperature, the temperature less than dew point easily makes wet air in metal safe wall
Phase transformation condensation is generated with the metal medium surface of electrical equipment.Although having installation heating plate inside some cabinets, because it is opened
Dynamic threshold value can not quantify, and the space heated is limited, and wet air is not inhibited effectively, so still holding very much
It is also easy to produce condensation.
In summary, it would be highly desirable to a kind of electrical equipment ensuring equipment for the Temperature and Humidity Control demand that can solve outdoor electric cabinet.
