Between gap setting have the cross-over block of predetermined number, temperature sensor, which is arranged on the top of the transformer body and connected, to be dissipated
Thermal, institute is leaded all to be drawn by terminal plate, and the bottom of the lower clamping piece is provided with least two reverse U shape feets.
In one of embodiment, the heat abstractor includes at least one of fin, radiating tube, ventilating fan.
In one of embodiment, the temperature sensor connects the ventilating fan, after temperature reaches predetermined threshold value, opens
Ventilating fan is opened to be radiated.
In one of embodiment, the insulation pressing and cross-over block are sleeper material.
In one of embodiment, the transformer also includes waterproof case at the top of V-type.
Transformer in the embodiment of the present invention reaches preferable radiating effect by a variety of radiating modes, temperature sensor
Setting makes heat abstractor become sensitive effective, and collets use sleeper material, and insulation effect is good and non-aging, anti-at the top of V-type
Water shell makes body avoid being attacked by sleet, practical, is suitable for large-scale promotion and application.
The additional aspect of the present invention and advantage will be set forth in part in the description, and these will become from the following description
Obtain substantially, or recognized by the practice of the present invention.

The consistent meaning of meaning, and unless by specific definitions as here, idealization or the implication of overly formal otherwise will not be used
To explain.
As shown in figure 1, the present invention provides a kind of transformer, the transformer includes：Iron core 1, winding 2, insulation pressing 3, absolutely
Edge cushion block 4, upper clamping piece 5, lower clamping piece 6, temperature sensor 7, heat abstractor 8, feet 9 and terminal plate 10, iron core 1 are located at upper folder
In bobbin between part 5 and lower clamping piece 6, winding 2 is wrapped on bobbin, and the gap setting between upper clamping piece 5 and winding 2 has
The insulation pressing 3 of predetermined number, the gap setting between lower clamping piece 6 and winding 2 have the cross-over block 4 of predetermined number, and temperature passes
Sensor 7 is arranged on the top of the transformer body and connects heat abstractor 8, and institute is leaded all to be drawn by terminal plate 10, institute
The bottom for stating lower clamping piece 6 is provided with least two reverse U shape feets 9, and the opening of feet 9 is outwardly.
Further, the heat abstractor 8 includes at least one of fin, radiating tube, ventilating fan.In winding 2
Periphery is provided with fin, is radiated by cross-ventilated mode, selectable, sets fuel tank radiating pipe device, fuel tank
Connected up and down with radiating tube, the oil in fuel tank is heated to be risen in the radiating tube extended, after temperature reduces, comes back to oil
Case, while the bottom of winding 2 is additionally provided with ventilating fan.
Preferably, the temperature sensor 7 connects the ventilating fan, after temperature reaches predetermined threshold value, opens ventilating fan
Radiated.Under normal circumstances, requirement can be reached by the radiating mode of fin or radiating tube, but when temperature occupies height not
When lower, the change that temperature sensor will experience temperature notes abnormalities, and when beyond default threshold value, will start bottom
Ventilating fan, transformer is set more to save and practical.
Preferably, the insulation pressing 3 and cross-over block 4 are sleeper material, because the influence of coil heating, in general are exhausted
Edge block, such as rubber heat up deformation, and aging occurs, and the anti-corrosive properties and bearing capacity of sleeper are all very good, and hardly
It is influenced by temperature.
Preferably, waterproof case 11 at the top of V-type, conventional transformer top shell are also included with reference to figure 2, the transformer
All it is flat, therefore sleet residence time can be very long, on the one hand can be corroded shell, on the other hand is also easy to pass through
Some gaps enter in transformer, therefore using waterproof case 11 at the top of V-type, not only solve these problems, and signal connects
Receive the reception that device 12 is more beneficial for signal on pinnacle.
Transformer in the embodiment of the present invention reaches preferable radiating effect by a variety of radiating modes, temperature sensor
Setting makes heat abstractor become sensitive effective, and collets use sleeper material, and insulation effect is good and non-aging, anti-at the top of V-type
Water shell makes body avoid being attacked by sleet, practical, is suitable for large-scale promotion and application.
Described above is only some embodiments of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
