Description

A kind of dry-type transformer
Technical field
The utility model belongs to field of electrical equipment, and in particular to a kind of dry-type transformer.
Background technology
Dry-type transformer just refers to the transformer that iron core and winding are not immersed in insulating oil, because dry-type transformer is safe Fire prevention, performance are good, so it is using quite varied.Due to being placed in outwork dry-type transformer, often by extraneous factor shadow more Ring, such as drenching with rain, Exposure to Sunlight, drenching with rain can cause high-voltage coil and low-voltage coil to make moist, and cause the insulating barrier resistance on its surface and reduce, there is leakage The possibility of electrical short;Traditional dry-type transformer high-voltage coil and low-voltage coil surface is provided with insulaion resistance, and Exposure to Sunlight can accelerate high-voltage line Insulaion resistance aging outside circle, reduces dry-type transformer service life.To ensure circuit clear, dry-type transformer needs continuous work Make, quick heating when dry-type transformer works, thermal resistance is big, typically using wind-cooling heat dissipating.But in traditional dry-type transformer, it is air-cooled Radiator is directly fixedly mounted at underframe, air-cooled radiator work when can continue produce vibration so that influence high-voltage coil and low-voltage coil and Iron core tight ness rating, and noise is produced, the service life of dry-type transformer is not only reduced, noise pollution is also created.Transformer In work, coil can produce magnetic shake by high-tension electricity, and iron core can be shaken loose for a long time.
Utility model content
To solve the problem of above technology is present, the utility model provides a kind of dry-type transformer, can reduce Exposure to Sunlight to height The aging action of insulating barrier on the outside of line ball circle, improves service life.
Its technical scheme is:
Low-voltage coil and high-tension coil, the insulation on low-voltage coil surface on a kind of dry-type transformer, including iron core, iron core Between resistance, the insulating barrier on high-tension coil surface, low-voltage coil and high-tension coil radiating road, the channel-section steel of iron core upper end both sides, Fixed air-cooled radiator on fixation steel plate, the underframe of fixation steel plate lower end, underframe and the fixation steel plate of iron core lower end both sides, its It is characterised by, the insulating barrier on the high-tension coil surface is made up of ceramics, is set in insulating barrier and be equipped with more than three heat-conducting glues vertically Rod.
Ceramics have the performances such as good insulating, high temperature resistant, and Exposure to Sunlight is very small on ceramics influence.High-tension coil can be adequately protected not By ectocine, it is to avoid the dangerous situation such as electric leakage, short circuit occurs, and improves service life.The high temperature that high-tension coil work is produced Conducted by heat conduction glue stick to surface of insulating layer, the wind that heat conduction glue stick is blown afloat with the extraneous temperature difference and air-cooled radiator makes heat quick Distribute to the external world, it is ensured that high-tension coil normal work.
Further, the channel-section steel of the iron core upper end contacts setting with iron core, and two groups of channel-section steel two ends are extended outside iron core, and are led to Threaded rod connection is crossed, rasp bar two ends are respectively cooperating with being provided with nut.Iron core is fixed by the channel-section steel of both sides by threaded rod, nut, Reinforcing can be periodically tightened, is safeguarded simple and convenient.
Further, quakeproof rubber pad is provided between the air-cooled radiator and underframe and fixation steel plate, air-cooled dissipate can be reduced Hot device noise pollution, mitigates resonance effect.
Further, roller is provided with the underframe, because volume of transformer is larger, the roller set on underframe can facilitate Transformer is moved.
Further, be fixedly installed weather shield on the iron core above the low-voltage coil and high-tension coil, weather shield with it is low Line ball circle and high-tension coil upper end are apart from 5-10cm.Weather shield can prevent rainwater from entering radiating road, so as to prevent high-voltage coil and low-voltage coil Make moist.
Further, both sides are fixedly installed hanger above the channel-section steel, can facilitate transformer lifting installation.
The beneficial effects of the utility model:
The utility model can reduce aging action of the Exposure to Sunlight to the insulating barrier on the outside of high-tension coil, raising makes using safety Use the life-span;Preventing from drenching with rain causes high-voltage coil and low-voltage coil to make moist, and reduces insulating barrier resistance, it is to avoid leak electricity short-circuit;Reduce air-cooled radiator Noise pollution, mitigates resonance effect.
