Description

A kind of modified dry-type transformer
Technical field
The utility model relates to a kind of dry-type transformer, particularly a kind of modified dry-type transformer.
Background technology
Transformer is a kind of static electrical equipment, utilizes electromagnetic induction principle between two or more coils, the voltage and current of a kind of grade is converted into the voltage and current of the another kind of grade of same frequency and transmits electric energy.Existing dry-type transformer relies primarily on cross-ventilation and cools down, and cooling effect is poor, it is impossible to tolerance high temperature;It addition, the moistest in many microclimates, ambient air humidity is relatively big through moisture, and the iron core of transformer, high-voltage coil and low-voltage coil make moist, and to be easily caused insulaion resistance on the low side, affect using effect, for solution the problems referred to above, it is necessary to make improvement.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, ventilation effect good, can in the environment of high temperature and humidity steady operation, it is ensured that the modified dry-type transformer of performance.
The utility model solves its technical problem and be the technical scheme is that
A kind of modified dry-type transformer, including base and the iron core being arranged on base, low pressure winding and high pressure winding it is sequentially provided with outside iron core, described low pressure winding and high pressure winding are externally provided with the epoxy resin poured body that they are cured as one, epoxy resin poured body is formed between low pressure winding and high pressure winding ventilation air gap, is positioned at low pressure winding and high pressure winding upper and lower end face is additionally provided with fan.
Wherein, described low pressure winding inwall is additionally provided with temperature sensor, and described temperature sensor electrically connects in fan with by control circuit plate.
It addition, described iron core is outer is also set with electrothermal layer between low pressure winding, described electrothermal layer is connected with control circuit plate.
Further, the shockproof rubber strip of strip it is provided with between described low pressure winding and high pressure winding.
The beneficial effects of the utility model are: by forming ventilation air gap in epoxy resin poured body between low pressure winding and high pressure winding, it is positioned at low pressure winding and high pressure winding upper and lower end face is additionally provided with fan, it is provided with temperature sensor at low pressure winding inwall, between low pressure winding, is also set with electrothermal layer outward at iron core, temperature sensor, electrothermal layer are connected with control circuit plate respectively.In high temperature environments, temperature sensor detects operating temperature, feed back to control circuit plate, when temperature is too high, circuit board controls fan work, is dried by fan, make wind through ventilation air gap, low pressure winding and high pressure winding are lowered the temperature so that the heat in transformer is discharged, thus reach the purpose of cooling;In wet environment, electrothermal layer, fan is started by control circuit plate, drying effect is played in electrothermal layer heating, utilize fan blowing can take away wet gas from ventilation air gap simultaneously, thus avoid the iron core of transformer, high-voltage coil and low-voltage coil makes moist and is easily caused insulaion resistance situation on the low side and occurs, it is ensured that the stability of transformer and service life.
Accompanying drawing explanation
With embodiment, the utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to Fig. 1, a kind of modified dry-type transformer, including base 1 and the iron core 2 being arranged on base 1, low pressure winding 3 and high pressure winding 4 it is sequentially provided with outside iron core 2, described low pressure winding 3 and high pressure winding 4 are externally provided with the epoxy resin poured body 5 that they are cured as one, epoxy resin poured body 5 is formed between low pressure winding 3 and high pressure winding 4 ventilation air gap 6, is positioned at low pressure winding 3 and the upper and lower end face of high pressure winding 4 is additionally provided with fan 7.
Wherein, described low pressure winding 3 inwall is additionally provided with temperature sensor 8, and described temperature sensor 8 electrically connects in fan 7 with by control circuit plate.
It addition, described iron core 2 is outer is also set with electrothermal layer 9 between low pressure winding 3, described electrothermal layer 9 is connected with control circuit plate.
In high temperature environments, temperature sensor 8 detects operating temperature, feed back to control circuit plate, when temperature is too high, circuit board controls fan 7 and works, and is dried by fan 7, make wind through ventilation air gap 6, low pressure winding 3 and high pressure winding 4 are lowered the temperature so that the heat in transformer is discharged, thus reach the purpose of cooling;In wet environment, electrothermal layer 9, fan 7 is started by control circuit plate, drying effect is played in electrothermal layer 9 heating, utilize fan 7 blowing can take away wet gas from ventilation air gap 6 simultaneously, thus avoid the iron core of transformer, high-voltage coil and low-voltage coil makes moist and is easily caused insulaion resistance situation on the low side and occurs, it is ensured that the stability of transformer and service life.
Again, the shockproof rubber strip 10 of strip it is provided with between described low pressure winding 3 and high pressure winding 4;Bringing noise owing to easily producing vibration when transformer works, during drying especially with fan 7, noise is more obvious, and after utilizing said structure, can effectively reduce noise, reduces the loss to equipment.
The utility model is rational in infrastructure, ventilation effect good, can in the environment of high temperature and humidity steady operation, it is ensured that performance, is a kind of modified dry-type transformer being widely used under various weather, environment.
