Problems solved by technology

[0003] When the transformer is in operation, it will generate a lot of heat. In the prior art, heat dissipation scales are usually arranged on the surface of the transformer to increase the heat dissipation area and achieve the effect of heat dissipation. In actual use, there is an abnormal situation of excessive temperature. If the abnormal high temperature is not repaired and maintained by manual intervention in time, it will easily affect the safe operation of the transformer, and even have certain potential safety hazards.

Embodiment 1

[0041] see Figure 1-2 , a self-extensible uplift early warning transformer, comprising a transformer body 1, a plurality of evenly distributed heat dissipation scales 2 are fixedly connected to the outer end of the transformer body 1, and thermal folding frames are fixedly connected to the left and right outer ends of the transformer body 1. The folding frame includes two uprights 4 fixedly connected to the transformer body 1, an outer brace 3 connected to the outer ends of the two uprights 4, an early warning column 5 connected between the middle of the outer brace 3 and the transformer body 1, and an outer brace 3 connected to The self-extending stacked tube 6 at the outer end corresponds to the early warning column 5, and the two columns 4 are respectively located on the upper and lower sides of the heat dissipation scale 2, and the outer support plate 3 is located outside the heat dissipation scale 2.

[0042] see Figure 3-5 The surface of the outer support plate 3 is d...

Embodiment 2

[0049] Such as Figure 9 Cotton velvet grains 13 are filled between the pre-extended outer section 621 and the pre-extended flat section 622, and the inside of the extended shaped end 61 is fixedly connected with a liquid storage bag 10 and a limiting ring, and the limiting ring is located near the outer surface of the liquid storage bag 10. On one side of the strut 3 , a plurality of fluid guiding groove holes 14 are drilled in the extended shaped end 61 , the fluid guiding groove holes 14 match the edge of the fluid storage bag 10 , and the fluid guiding groove holes 14 communicate with the laminated ring and the fluid storage bag 10 ,Such as Figure 11-12 , when extending outward from the elongated stacked tube 6, the elastic rope 11 pulls the liquid blocking ball 103 to separate it from the liquid guiding groove hole 14, so that the color liquid penetrates into the laminated ring along the liquid guiding groove hole 14 , so that the cotton velvet particles 13 absorb and c...

Embodiment 3

[0054] see Figure 13 Cotton velvet particles 13 include a color-absorbing pile tail 131, a floating ball layer 133 fixedly connected to the end of the color-absorbing pile tail 131, and an outer water-soluble layer 132 wrapped outside the floating ball layer 133, and the outer water-soluble layer 132 is used for dispensing Heavy, so that the cotton velvet particles 13 are not easy to attach to the inner wall of the pre-stretched outer section 621 under normal conditions, the floating ball layer 133 is filled with helium, and the color liquid enters the pre-stretched outer section 621 and the pre-stretched flat section 622 At the back, the outer wrapping water-soluble layer 132 is water-soluble, while the buoyant layer 133 is exposed and expands under high temperature, so that the hairiness has a certain buoyancy, and gathers to the upper inner wall of the pre-stretching outer section 621, so that the self-stretching The color change of stack tube 6 is more obvious, and the wa...

Abstract

The invention discloses an early warning type transformer capable of stretching and protruding automatically, and belongs to the field of transformers. A thermal folding frame is arranged in the middle of the surface of the transformer; when the surface temperature of the transformer is too high, a thermal cracking rod expands and bursts, so that a self-extending folded pipe rapidly extends and expands outwards, and pulls a thermal arch covering sheet, the thermal arch covering sheet is gradually folded from the sheet shape to the middle part so as to present a protruding shape, so that a dual deformation early warning effect is realized for a worker, the worker is visually reminded of abnormal temperature in time, the worker can conveniently carry out manual intervention in time, potential safety hazards are eliminated or reduced in time; and in addition, in the expansion process of the self-extending folded pipe, when the surface of the self-extending folded pipe changes color, it is indicated that the abnormal temperature rising condition of the transformer is emergent, and early warning upgrading for workers is achieved.

Description

technical field [0001] The invention relates to the field of transformers, and more specifically relates to a self-extensible bulge early warning transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). Transformer cooling refers to dissipating the heat generated by the running transformer through certain methods. When the transformer is running, the heat generated by the loss of the winding and core must be dissipated in time to avoid insulation damage caused by overheating. For small-capacity transformers, the ratio of the outer surface area to the volume of the transformer is relatively large, and a self-cooling method can be used to dissipate heat through radiation and natural convection. [0003] When the transformer is in operation, it will generate a lot of heat. In the prior art, heat dissipation sc...
