Description
Technical field
This utility model is related to power transformer equipment technical field, cold particularly to a kind of Power-saving-type Power Transformer
But mechanism.
Background technology
Current transformator is equipped with transformer oil, and in order to reduce the temperature of transformer oil, setting reduces temperature of oil in transformer
The heat sink of degree, existing heat sink is to arrange a flat cooling box in oil tank of transformer side, under cooling box
End plugs multiple flat cooling monomers, and this setting is passed through to increase the area of dissipation of transformer oil, to strengthen radiating effect, but its
Gap between multiple cooling monomers is little, atmosphere draught-free, and heat is easily assembled in gap location, leads to the scattered of monomer surface that radiate
Thermal effect is deteriorated；And this heat abstractor all made using metal, manufacturing cost is high, complex structure, installation difficulty, transformer oil
Radiating circulation rate is slow, easily leads to transformer damage because transformer oil temperature is too high.
Transformator operationally can produce substantial amounts of heat it is necessary in time heat transfer be gone out, and otherwise can cause transformation
Temperature within device rises, the work efficiency of impact transformator.Temperature is too high or even transformator can be caused to burn, and causes electric power thing
Therefore, huge loss can be brought to user.Main transformer in peak times of power consumption, the often longtime running of over-saturation degree, though
So come with cooler on main transformer, but because main transformer is after the longtime running of over-saturation degree, extreme temperatures, from
The cooler of band is difficult to meet the cooling needs of main transformer, and then leads to the Frequent Accidents that main transformer is burned, to power supply
Safety brings potential safety hazard, and has a strong impact on the normal electricity consumption of resident and industrial and mining establishment.
Transformer oil is to constitute one of material of transformator major insulation, for insulation, especially for supertension Large Copacity
Transformator, the height of its gas content of oil has considerable influence to transformer insulated, and this is because gas may be assembled in equipment
Get up and form bubble, the bubble being formed particularly when temperature and pressure declines suddenly, it is gathered in insulating paper layer or surface
Shi Rongyi produces shelf depreciation.Transformer oil easily oil temperature in the course of the work and raises, and the oil temperature after rising easily produces
Bubble, easily causes the oxidation of transformer equipment, transformator oil leak, causes air accumulation after repairing in Buchholz relay, oil
Position meter vacation instruction, patrol officer does not find, there's a sudden fall in temperature in time, and the air precipitation of dissolving in oil enters Buchholz relay and leads to weight
Car is jumped in protection action.
The heat sink commonly used at present has: cooling air conditioner or cooling fan etc., they all have certain pluses and minuses；
Cooling air conditioner, it has good cooling effect, but complex structure, energy consumption are big, expensive；Cooled using subsoil water and deposit
Running, part is few, structure is relatively simple, but water consumption is larger, and cooling-down effect is also not ideal；And use cooling fan to lower the temperature,
Rotated by cooling fan, accelerate the air flow around transformator, make transformator surface and the air of flowing carry out heat exchange,
Though its structure is simple, water consumption is low, due to summer ambient temperature natively very high so that transformator is lowered the temperature by air flow
Effect poor.In addition, arranging shower nozzle by Water spray to change also by transformer body and radiating tube surrounding in prior art
On depressor fin, transformator is made to lower the temperature, entitled a kind of transformer Cooling as disclosed in patent No. cn201220661381.4
Heat sink, it includes the devices such as control valve, spray equipment, automaton and ups power supply.This kind of spraying ventilating device is deposited
In following shortcoming: one is complex structure, and the effective area spraying on fin is little, and cooling-down effect is poor.Two is chiller
Work is dangerous, because being arranged on components and parts and the circuit of transformator surrounding, near electric conductor, easily causes the first device of device itself
The burning it is impossible to work with remaining valid, installation and repairing there is also potential safety hazard simultaneously of part；Three is that spray equipment water consumption is big,
It is unable to efficient utilization water resource.Accordingly, it would be desirable to research and develop safely and efficiently transformator water cooling system further.
Publication date is on January 16th, 2013, and the patent document of Publication No. 102881408a discloses a kind of cooling certainly and becomes
Depressor, including the transformator being made up of the iron core of the first winding, the second winding and winding the first winding and the second winding originally
Body, transformer body is installed on one block of pcb plate by support, and pcb plate is provided with power supply produced by transformer body to be come
The semiconductor chilling plate driving.It is disadvantageous in that: the heat that this transformator produces is difficult to exhale rapidly, affect transformation
The work efficiency of device.What is more important: in hot calm summer, rely on above-mentioned heat abstractor substantially can not drop to transformator
Temperature, transformator is all mounted in and lives on building on concrete floor, and concrete floor absorbs substantial amounts of heat, is now resident to evening
Peak times of power consumption, the load that transformator bears is more than daytime, and the heat that transformator produces is many, and can not disperse, now cement
, to transformator, the heat radiation that on the other hand above all concrete floor produces, radiation is in transformation for the heat one side conduction of heat on ground
Device, causes transformator high temperature, and main transformer is easily burned, and brings potential safety hazard to power supply safety, and has a strong impact on resident
Normal electricity consumption with industrial and mining establishment.
Utility model content
Problem to be solved in the utility model is the above-mentioned deficiency overcoming prior art, provides a kind of energy-saving electric power to become
The cooling body of depressor, this transformator need not install radiator fan, need not spray, good cooling effect, safe and reliable to operation.
