Height, promotes the service life of dry-type transformer.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:
A kind of can the dry-type transformer of high efficiency and heat radiation, including guard shield and be arranged on outside described protection
Transformer body in shell, described transformer body includes iron core, low pressure winding and high pressure winding, described
Low pressure winding and described high pressure winding are sequentially coaxially enclosed within described iron core, described low pressure winding and described height
Being provided with cooling ring between pressure winding, the middle part of described cooling ring is hollow region, and described hollow region is used as
Air-cooled passage, be provided with in described air-cooled passage many axially through water-cooling channel, described air-cooled passage
Bottom connect have cooling fan, be provided with the coolant of flow circuit in described water-cooling channel.
Further, it is provided with quakeproof rubber pad between described transformer body and described guard shield.
Further, described guard shield on cover and be provided with exhaust outlet.
Further, described coolant is distilled water.
Further, the pipeline that described water-cooling channel is made up of PVC material.
Relative to prior art, of the present invention can the dry-type transformer of high efficiency and heat radiation have following excellent
Gesture:
Being provided with cooling ring between low pressure winding and high pressure winding, the air-cooled passage bottom of cooling ring connects scattered
Hot-air blower, air-cooled passage can be strengthened the air circulation between high pressure winding and low pressure winding, play heat radiation
The effect of cooling；Coolant in water-cooling channel can simultaneously circulation, play the effect of water-cooling,
By cooling ring, it is possible to utilize water-cooled and air-cooled two kinds of radiating modes simultaneously, heat radiation is more uniform, transformation
The temperature of device body pieces declines simultaneously, improves radiating efficiency, contributes to increasing the service life.
The quakeproof rubber pad being provided with between transformer body and guard shield, it is possible to play the effect of damping,
Greatly reduce the vibrations of transformer body self, reduce noise；The exhaust outlet that guard shield is provided with,
Cross-ventilation can be strengthened, strengthen heat-sinking capability；With coolant as distilled water, the specific heat capacitive of distilled water
Can be strong, there is good liquid fluidity, cost performance is high；The pipe that water-cooling channel is made up of PVC material
Road, has high anti-pressure ability, has good heat conductivility.
