Background technology
With the continuous development of society, people are also increasing to the demand of electric power, especially in annual peak of power consumption
In winter summer phase, often transformer works overloadingly, and most transformers are substantial amounts of warm because overwork produces, it is impossible to dissipates in time
Go out to cause transformer to be stopped or occur transformer damage, or even cause the phenomenon of Explosion of Transformer, not only have a strong impact on
The production and living of the people, and the damage of power equipment is also result in, caused damage to country, analyze its reason：
During transformer station high-voltage side bus, heat caused by the loss in winding and iron core must dissipate away in time, in order to avoid overheat
And cause insulation damages；For small capacity transformer, external surface area and the ratio between transformer volume are relatively large, can use self cooling
Mode, heat can be dispersed by radiation and free convection；Also oil immersed type can be used；Self cooling mode becomes suitable for indoor small
Depressor, for fire preventing, typically using dry type, without oil immersion；But because subregion power supply pressure is big, it can also use oil immersion
Formula transformer is powered, but heat radiation cooling device is conventional oil, but the cooling of air is often due to gas
Specific heat capacity is smaller, the thermal Finite for taking away it；Because the loss of transformer is proportional to its volume, so as transformer holds
The increase of amount, its volume and loss will be increased with core dimensions cube, and the quadratic power increase that external surface area is only sized.Cause
This, high-power transformer is unshakable in one's determination and winding should be immersed in oil, it is necessary to be cooled down using other cooling provisions, and need by setting
Put monitoring device and the generation for avoiding danger is monitored to it.

A kind of water-cooled transformer iron core cooling means is disclosed in the A of CN 103714948, it is characterised in that：Described
Core interior uses recirculated water cooling method.Heretofore described core interior uses recirculated water cooling method, efficiently avoid
Because transformer fe core diameter is big, unit area thermic load is big, and heat conduction path is very long, and caused damage is transferred out inside iron core
Consumption is greatly so as to cause the overheat of iron core to cause scaling loss, and because iron core is effectively cooled down, temperature is effectively obtained control will not
Producing overheat causes scaling loss, so the diameter of iron core can be reduced, so as to reduce the loss of core material, and its water cooling transformation therewith
The material of device main body also can obtain corresponding reduction, while also ensure that comprehensive radiating effect of water-cooled transformer, improves and uses
Life-span.But the present apparatus is because the water used is medium, and the specific heat capacity of water is smaller, it is easy to due to boiling water build-up of pressure mistake
Greatly, so as to producing the phenomenon of leak or gas leakage, potential safety hazard is increased, and because it does not design the method for reply safety monitoring,
Not only bad for the stabilization of transformer in transformer station, and increase the input and the input of equipment of staff.
