Description

Technical Field

[0001] This invention relates to the field of transformers, and in particular to a transformer with a lightning protection structure. Background Technology

[0002] Oil-immersed wound core transformers operate based on the principle of electromagnetic induction. When the primary winding is connected to an AC power source, an alternating magnetic flux is generated in the core. This alternating magnetic flux induces an electromotive force in the secondary winding, thereby realizing the transfer of electrical energy and the transformation of voltage. Transformer oil, as an insulating and cooling medium, circulates in the tank, carrying away the heat generated by the core and windings, ensuring the normal operation of the transformer. Transformers generate a lot of heat during use, especially in the hot summer, requiring heat dissipation. The current method involves installing heat dissipation fins on the transformer and spraying water on the side walls to cool it down. However, this method is inefficient and wastes a lot of water.

Detailed Implementation

[0015] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0016] This invention discloses a transformer with a lightning protection structure, including a transformer body 1. L-shaped frames 8 are fixedly installed at both ends of the transformer body 1. The bottom of the L-shaped frames 8 is fixedly installed on the top of the support base 2. A support frame seat 4 is fixedly installed at one end of the transformer body 1. An oil storage pillow 3 is installed on the support frame seat 4. Heat dissipation fins 5 are provided on both sides of the transformer body 1. A water outlet pipe 6 is provided above the heat dissipation fins 5. A lifting structure is provided at the two L-shaped frames 8. The lifting structure drives the water collection frame 7 to move up and down. Two driving components are installed on the outer wall of the water collection frame 7. The driving components drive the moving plate 12 to move. A lightning rod 29 is fixedly installed on the top of the transformer body 1. A protective structure for protecting the lightning rod 29 is also installed on the top of the transformer body 1. The lifting structure includes a first servo motor 18 mounted on the top of the support base 2. The output end of the first servo motor 18 is connected to one end of a first lead screw 19, and the other end of the first lead screw 19 is mounted to a bearing seat at the bottom of the L-shaped frame 8 via a bearing. The first lead screw 19 is also fitted with a lead sleeve block 20. One end of the lead sleeve block 20 is fixedly mounted to a movable frame 15, which moves up and down on the L-shaped frame 8. Support blocks 14 are provided at both ends of the water collection frame 7, and the support blocks 14 are fixedly mounted to the movable frame 15. The installation includes a U-shaped seat 16 on one side of the movable frame 15, a cylinder 17 fixedly mounted on the side wall of the U-shaped seat 16, and the output end of the cylinder 17 inserted into a corresponding fixing hole on the L-shaped frame 8. Several fixing holes are provided on the outer wall of the L-shaped frame 8. The drive assembly includes an L-shaped block 39 mounted on the outer wall of the water collection frame 7, a motor 40 mounted on the inner wall of the L-shaped block 39, and a drive gear 41 mounted on the output end of the motor 40. The drive gear 41 meshes with a transmission rack 42. One end is fixedly installed on the movable plate 12. One end of the movable plate 12 is provided with a sealing strip 13. When it is necessary to increase the heat dissipation effect of the transformer body 1, the two movable plates 12 located on the water collection frame 7 below the transformer body 1 will slowly unfold outward. The motor 40 on the L-shaped block 39 works, driving the drive gear 41 to rotate. While the drive gear 41 rotates, the transmission rack 42 will move accordingly, causing the movable plate 12 to slowly unfold outward. The first servo motor 18 in the lifting structure works, driving the first lead screw 19 to rotate. While the first lead screw 19 rotates, it will drive the water collection frame 7 to move upward. After the water collection frame 7 moves to the appropriate position, the cylinder 17 on the U-shaped seat 16 works. The output end of the cylinder 17 will be inserted into the corresponding fixing hole opened on the L-shaped frame 8, so that the water collection frame 7 covers the transformer body 1. Water will spray out from the water outlet pipe 6, and the water will be collected in the water collection frame 7, so that a part of the transformer body 1 will be immersed in the water collection frame 7, which will provide better heat dissipation for the transformer body 1.

[0017] See Figure 1 and Figure 5The protective structure includes a mounting base 21 fixedly installed on the top of the transformer body 1. The mounting base 21 has two first slots 24. A second servo motor 22 is fixedly installed at one end of the mounting base 21. The output end of the second servo motor 22 is connected to a second lead screw 23, which is a bidirectional lead screw. A first moving block 25 and a second moving block 27 are adapted to be installed on the second lead screw 23. One end of the first moving block 25 is connected to a first protective cover 26, and one end of the second moving block 27 is fixedly connected to a second protective cover 28. The top of block 25 and the second moving block 27 are provided with guide flanges, and the guide flanges move in the groove opened in the top wall of the first slot 24. When it is raining, the second servo motor 22 on the top of the transformer body 1 works, driving the second lead screw 23 to rotate. Since the second lead screw 23 is a bidirectional lead screw, the corresponding first protective cover 26 and second protective cover 28 will slowly unfold, and the lightning rod 29 will work. When it is sunny, the first protective cover 26 and the second protective cover 28 will shield the lightning rod 29 and protect it.

[0018] See Figure 1 , Figure 4 and Figure 6 The support base 2 has clamping structures installed on the poles at both ends. The bottom of the support base 2 has a limiting component for limiting and fixing the clamping structures. The clamping structure includes a clamping seat 30 fixedly installed on the support base 2. The clamping seat 30 has a second slot 31. One end of the clamping seat 30 has a third slot 33 connected to the second slot 31. A rotating lead screw 32 is installed in the second slot 31. The lead screw 32 is a bidirectional lead screw. The lead screw 32 is fitted with a corresponding lead screw block 34. One end of the lead screw block 34 is fixedly installed between a protrusion and a clamping clamp 35. One end of the clamping clamp 35 is fixedly installed with an L-shaped protrusion 36. The L-shaped protrusion 36 has... The device has a first T-shaped groove, and an L-shaped protrusion 36 is fitted and installed with a corresponding locking component. The locking component includes a locking block 37, and two second T-shaped blocks 38 are provided at one end of the locking block 37. The corresponding second T-shaped blocks 38 are inserted into the corresponding first T-shaped groove. The limiting component includes a fixing block 9 fixedly installed at the bottom of the corresponding locking seat 30. The fixing block 9 has a second T-shaped groove, and a first T-shaped block 11 is inserted into the second T-shaped groove. The first T-shaped block 11 is fixedly installed on the limiting plate 10. After the two clamping hoops 35 are fixedly clamped to the power pole, the second T-shaped blocks 38 on the locking block 37 are inserted into the corresponding T-shaped grooves on the L-shaped protrusion 36, thereby increasing the stability of the clamping hoops 35.

[0019] The implementation principle of a transformer with a lightning protection structure according to an embodiment of the present invention is as follows: During hot summer months, when increased heat dissipation is needed for the transformer body 1, two movable plates 12 on the water collection frame 7 located below the transformer body 1 will slowly unfold outwards. The motor 40 on the L-shaped block 39 will operate, driving the drive gear 41 to rotate. Simultaneously, the drive gear 41 rotates, causing the transmission rack 42 to move accordingly, thus slowly unfolding the movable plates 12 outwards. The first servo motor 18 in the lifting structure will operate, driving the first lead screw 19 to rotate. Simultaneously, the first lead screw 19 will rotate, causing the water collection frame 7 to move upwards. After the water collection frame 7 moves to the appropriate position, the cylinder 17 on the U-shaped seat 16 will operate, and the output end of the cylinder 17 will insert into the corresponding fixing hole on the L-shaped frame 8, causing the water collection frame 7 to cover the transformer body 1. Water will spray from the water outlet pipe 6, and the water will be collected in the water collection frame 7. Inside, a portion of the transformer body 1 will be immersed in the water collection frame 7, which will provide better heat dissipation for the transformer body 1. The water in the water collection frame 7 can also flow out through the water outlet at the bottom of the water collection frame 7 to replace the water in the water collection frame 7. The operation is also relatively convenient. When it rains, the second servo motor 22 on the top of the transformer body 1 will work, driving the second lead screw 23 to rotate. Since the second lead screw 23 is a bidirectional lead screw, the corresponding first protective cover 26 and second protective cover 28 will slowly unfold, and the lightning rod 29 will work. When it is sunny, the first protective cover 26 and the second protective cover 28 will shield the lightning rod 29 and protect it. After the two clamping hoops 35 are fixed and clamped to the pole, the second T-shaped block 38 on the clamping block 37 is inserted into the corresponding T-shaped groove on the L-shaped protrusion 36, which can increase the stability of the clamping hoop 35.

[0020] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
