Description
Technical field
The present invention relates to controller switching equipment technical fields, and in particular to a kind of oil-immersed transformer that heat dissipation performance is excellent.
Background technology
Oil-immersed transformer belongs to a kind of structure type of transformer, and working condition lower coil is impregnated in the oil, has body
The features such as accumulating strong big, at low cost, easy to maintenance, good heat dissipation, capability of overload, good environmental adaptability, current electricity online operation
Most of power transformer is still oily type transformer, wherein ensureing that the excellent heat dispersion performance of transformer is the key technology of transformer
One of performance.There are mainly four types of the current types of cooling of oily type transformer both at home and abroad, i.e. Natural Oil Circulation Power self-cold radiating, natural oil
Circulating air cooling heat dissipation, forced oil-circulation wind-cooling heat dissipating and forced oil circulation water-cooling heat dissipation.
Natural Oil Circulation Power self-cold radiating is suitable for small-sized oily type transformer, and generally use gilled radiator radiates；From
So oil circulating air cooling radiating mode is using after transformer winding and iron core fever, and intrinsic oil forms convection current, and oil stream is through dissipating
After hot device, the wind blown out by cooling fan takes away heat, to reach heat dissipation purpose；Forced oil-circulation wind-cooling heat dissipating mode is more
For in especially big and large and medium-sized oily type transformer, mainly making the oil in transformer be forced Rapid Circulation by the effect of oil pump,
When oil stream is through radiator, the wind blown out by cooling fan takes away heat.This kind of radiating mode generally use forced air cooler, it is air-cooled
But transformer top layer high temperature oil is sent into cooling tube by device by oil pump, and the heat generated is transmitted to cooling inside pipe wall and wing
Piece, then will will be in heat dissipation to air by cooling fan blowing；Forced oil circulation water-cooling heat dissipation generally use water cooler is made
For big, oversize transformer heat-exchange device, since the specific heat of air is only the 1/4 of water, so water cooler compares air cooling
Device good cooling results, and since the heat transfer coefficient of the ratio of heat transfer coefficient water of air is low, therefore under the premise of cooling capacity is identical, water
Cooler is more small than forced air cooler, light-weight low with noise, but there are cooling copper tube ruptures to cause in water cooler
Cooling water enters the phenomenon in transformer oil, due to that can not find that water has enter into transformer oil in time, often makes into water
Transformer oil insulation performance significantly decline, to cause transformer to occur major accident in the process of running, influence is very
Badly.
In conclusion the heat dissipation effect unobvious of forced air cooler, easily cause transformer and are burnt because heat dissipation is uneven, water cooling
But the good heat dissipation effect of device, but but there is certain risk in water cooler, be likely to result in transformer and send out in the process of running
Raw major accident in order to maintain preferable heat dissipation performance,
