Background technology
In the past several years, due to being significantly increased for industrial and residential electricity consumption, long-distance sand transport electric power is more and more universal,
Therefore the operating power of transformer is in lasting raising, while electronics industry requires that power network or local power must be reliably and steady
Fixed, the requirement to the safety in operation and reliability of transformer is also being improved.Dry-type transformer mainly enters by cross-ventilation
Row cooling, iron core and winding are not immersed in insulating oil.The safe operation of dry-type transformer and service life, largely take
Certainly in the safe and reliable of Transformer Winding insulation.
But improved with the power of transformer, eddy-current heating and coil heating are also correspondingly improved, particularly in core body
With occurring the high temperature of part near coil, this can not only reduce power and service life, and the serious power supply that also results in is asked
Topic, this is a necessary problems faced in the structure of dry-type transformer.Simultaneously because the difference of weather in all parts of the country, makes
The problem of with that will run into different during transformer.More moist in some microclimates, ambient air humidity is larger through moisture,
Transformer makes moist, and to be easily caused insulaion resistance relatively low, is mainly reflected in iron core, high-voltage coil and low-voltage coil makes moist causes insulaion resistance relatively low.
Therefore, a kind of cheap, reliable operation of research and development, the dry type transformation of energy automatic temperature-control humidity easy for installation
Device, is with a wide range of applications.
Utility model content
The purpose of this utility model is a kind of cheap, reliable operation of offer, and energy automatic temperature-control easy for installation is wet
The dry-type transformer of degree.
The purpose of this utility model is achieved in that including folder, winding, arm-tie, base；During described winding includes
The iron core of the heart, the low pressure winding of outer layer and high pressure winding；Respectively constituted between described iron core, low pressure winding and high pressure winding logical
Wind passage；The affixed heating film of described iron core and the outer surface of low pressure winding；TEMP is set inside described vent passages
Device and humidity sensor；The affixed blower fan of described chassis interior, and the top surface of base sets air port；Described base inner blower,
Temperature sensor and humidity sensor are electrically connected with controller respectively.
The utility model uses the structure that dry-type transformer and temperature sensor, humidity sensor are combined, and solves core
The problem of near coil with there is localized hyperthermia in body, while solving iron core, high-voltage coil and low-voltage coil in wet condition may make moist
Cause the problem of insulaion resistance is relatively low, improve the safe and reliable of Transformer Winding insulation.The utility model is simple in construction, cost
It is cheap.

Air port；The described inner blower of base 5, heating film 21, temperature sensor 6 and humidity sensor 7 electrically connects with controller 4 respectively
Connect.
Described vent passages 23 are circular passage.
The width range of described vent passages 23 is 7 ~ 25mm.
Described heating film 21 is netted heating film.
The temperature sensor 6 and humidity sensor 7 that the described inside of vent passages 23 is set are 3 ~ 12.
The arrangement mode that described temperature sensor 6 and the arrangement mode of humidity sensor 7 is divided equally using layering.
Operation principle and the course of work of the present utility model：
The utility model uses the structure that dry-type transformer and temperature sensor, humidity sensor are combined, in transformer
During work, temperature sensor, the humidity sensor constantly humiture change of monitoring inside transformer in real time, while real by controller
When compare the data that threshold value and temperature and relative humidity in storage are transmitted.When temperature exceedes set threshold value, controller
Open blower fan progress strong cold；When humidity exceedes set threshold value, controller opens heating film and blower fan carries out wet down processing.
