Description

Technical Field

[0002] Transformers are basic equipment for power transmission and distribution, and are widely used in industries, agriculture, transportation, urban communities, and other fields. Transformers are devices that use the principle of electromagnetic induction to change AC voltage. The main components are primary coils, secondary coils, and iron cores (magnetic cores). The main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] The transformer is generally composed of a transformer main structure, mounting feet and a radiator. The mounting feet are used to install and fix the transformer, and the radiator is used to dissipate the large amount of heat generated by the transformer during operation to the external environment, thereby ensuring the long-term stable and normal operation of the transformer. When installing the transformer, in order to maintain the normal operation of the transformer, workers are often required to install a frame to stably place the transformer. When installing the existing transformer, the mounting feet and the frame are only connected by bolts, but the spacing between the mounting feet of transformers of different specifications is different, and the existing transformer frame structure is too rigid to meet the installation requirements of transformers of various specifications. The installation spacing cannot be adjusted according to the distance between the transformer mounting feet. For transformers of different specifications, corresponding frame structures need to be designed, resulting in waste of materials, and the function is too single, and it cannot assist in the heat dissipation of the transformer, and cannot guarantee the safety of the transformer to the greatest extent.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example

[0028] like Figure 1-3 As shown, a transformer frame structure proposed in one embodiment of the present invention includes a fixing frame, a spacing adjustment mechanism 2 and an auxiliary heat dissipation device 3, which are specifically as follows:

[0029] The fixed frame is similar to a stretcher structure, and comprises two parallel front and rear horizontal plates 1, which are used as main load-bearing beams. A sliding track 101 is respectively provided on the two horizontal plates 1, and two slides 102 are slidably matched on the front and rear sliding tracks 101. The corresponding front and rear slides 102 on the two sliding tracks 101 are respectively fixedly connected by fixing rods 103, and the front and rear slides 102 are connected into a platform group by the fixing rods 103, and the transformer is installed on the platform group;

[0030] The spacing adjustment mechanism 2 is installed on the two slides 102 of one of the horizontal plates 1 on the fixed frame, and is used for bidirectional synchronous adjustment of the spacing between the two slides 102 on the front and rear sliding rails 101. One adjustment can make the two slides 102 move synchronously relative to each other along the two sliding rails 101, approaching or moving away from each other. Due to the different spacings between the mounting feet of transformers of different sizes, the spacing adjustment mechanism 2 is set to adjust the spacing between the two slides 102 on the same sliding rail 101, and adjust the spacing between the two slides 102 to the same length as the spacing between the two mounting feet of the transformer to be installed, which can meet the installation requirements of transformers of different sizes;

[0031] The auxiliary heat dissipation device 3 is mounted on the two slides 102 and is used for conducting heat and assisting heat dissipation of the radiator of the transformer. The setting of the auxiliary heat dissipation device 3 can increase the heat dissipation area of ​​the transformer radiator and ensure the heat dissipation effect.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, the two horizontal plates 1 are connected and fixed by a longitudinal beam 104 to ensure the stability and reliability of the fixed frame structure. The horizontal plate 1 is provided with a threaded long groove 105 for installing the transformer, and the slide 102 is provided with connecting screw holes 1021 corresponding to the threaded long groove 105 above and below. The threaded long groove 105 is designed to cooperate with the transformer mounting foot, and the distance between the two slides 102 can be adjusted front and back within the length range of the threaded long groove 105 to meet the installation requirements.

[0033] like Figure 1 As shown, in some embodiments, the spacing adjustment mechanism 2 includes a bidirectional threaded rod 201, a nut seat 202 and a positioning seat 203. The nut seat 202 is connected to the outer wall of the slide 102. The nut seat 202 is composed of a nut and an outer sleeve seat. The outer sleeve seat is fixedly connected to the slide 102, and the nut is arranged inside the outer sleeve seat. The bidirectional threaded rod 201 is threadedly connected to the nut. The positioning seat 203 is fixedly connected to the cross plate 1 through a connecting rod 204, and the positioning seat 203 is rotatably connected to the middle part of the bidirectional threaded rod 201. When in use, only the bidirectional threaded rod 201 needs to be rotated forward or reversely to make the two nut seats 202 and the two slides 102 connected thereto move closer to each other or away from each other in a straight line, so as to achieve the purpose of adjusting the spacing between the two slides 102.

[0034] like Figure 1 As shown, in the above embodiment, in order to quickly and accurately adjust the spacing between the two slides 102, a scale 205 is set on the side of the positioning seat 203 away from the cross plate 1. The scale 205 can be designed to be a middle position zero point, and a distance measuring structure of scale lines is arranged on both sides starting from the zero point. The middle part of the scale 205 corresponds to the position of the positioning seat 203. After the spacing between the mounting feet of the transformer to be installed is known, it is only necessary to adjust the original spacing between the two slides 102 to the same spacing between the mounting feet of the transformer to be installed according to the spacing, that is, when the spacing between the mounting feet of the transformer to be installed is 45cm, the original spacing between the two slides 102 is 35cm. When adjusting the spacing between the two slides 102, it is only necessary to rotate the bidirectional threaded rod 201 in the opposite direction, and drive the slide 102 to make a linear motion away from the positioning seat 203 through the nut seat 202. After the slide 102 on one side slides 5cm, the sum of the synchronous sliding of the two slides 102 by 5cm is 10cm, and the spacing adjustment is completed.

[0035] like Figure 1As shown, in some embodiments, the auxiliary heat dissipation device 3 includes a lap rod 301, a lap bracket 302, and a heat dissipation unit 303 lapped on the lap rod 301 and the lap bracket 302. Two lap rods 301 are provided, and the two lap rods 301 are correspondingly connected to the two slides 102 of the two sliding rails 101. The slide 102 is provided with a slide groove that slides with the lap rod 301. Two lap brackets 302 are provided, and the two lap brackets 302 are respectively installed on the outer side walls of the two fixed rods 103. A heat dissipation unit 303 is respectively clamped on each heat dissipation fin of the front, rear, left and right radiators of the transformer. Each heat dissipation unit 303 located in the front and rear radiators of the transformer is respectively lapped on the lap rod 301, and each heat dissipation unit 303 located in the left and right radiators of the transformer is respectively lapped on the lap bracket 302. The heat dissipation unit 303 quickly conducts the heat on the heat dissipation fin to the heat dissipation unit 303, thereby increasing the heat dissipation area of ​​each radiator, thereby achieving the effect of improving the heat dissipation efficiency of the transformer.

[0036] like Figure 3 As shown, in the above embodiment, the heat dissipation unit 303 includes a heat dissipation body 3031, one side of the heat dissipation body 3031 is connected to two heat dissipation fins 3032 arranged in parallel, the heat dissipation fins 3032 are provided with overlapping grooves 3033 adapted to the overlapping rods 301 and the overlapping brackets 302, and the other side of the heat dissipation body 3031 is connected to a heat conduction part 3034, and the heat conduction part 3034 is provided with a clamping groove 3035 for clamping the heat sink. When installing, the clamping groove 3035 on the heat conduction part 3034 is opposite to the heat sink, and the heat sink is clamped into the clamping groove 3035. At this time, the bottom overlapping groove 3033 of the heat dissipation body 3031 is aligned with the overlapping rod 301 or the overlapping bracket 302 in the upper and lower directions. Yes, press down the heat dissipation body 3031 so that the heat dissipation body 3031 is overlapped in the overlap groove 3033 of the overlap rod 301 or the overlap bracket 302. At this time, the bottom end of the heat conduction part 3034 is abutted against the bottom plate of the radiator, and the assembly operation of the heat dissipation unit 303 is completed. The heat generated by the transformer is discharged by the external radiator, and the heat on the radiator is conducted to the heat dissipation body 3031 and the heat dissipation fins 3032 by the heat conduction part 3034. The heat dissipation fins 3032 and the radiator jointly dissipate heat for the transformer. Compared with the traditional transformer structure with only a radiator, the present invention designs a transformer frame structure including the heat dissipation unit 303 to make the heat dissipation speed of the transformer faster and the heat dissipation effect better.

[0037] The present invention also provides a transformer, including a transformer body 4 and the above-mentioned transformer frame structure, wherein two parallel feet 5 are provided at the bottom of the transformer body 4, and the feet 5 are the mounting feet of the transformer mentioned above, and the two ends of the feet 5 are respectively overlapped on the corresponding front and rear slides 102 on the front and rear sliding rails 101, and the feet 5 are provided with mounting holes 6 corresponding to the threaded long grooves 105, and the cross plate 1 and the feet 5 are fixed by bolts; during installation, the feet 5 of the transformer body 4 are placed on the front and rear slides 102 accordingly, so that the mounting holes 6 on the feet 5 correspond to the connecting screw holes 1021 on the slide 102 and the threaded long grooves 105 on the cross plate 1, and the bolts penetrate the mounting holes 6, the connecting screw holes 1021 and are threadedly connected with the threaded long grooves 105, so that the transformer body 4 is stably mounted on the fixed frame.
