[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). A transformer is one of the main equipment in a power plant.

[0003] When installing a transformer, a transformer bracket is required. Currently, the transformer bracket is usually welded by multiple metal components. To facilitate the connection between the bracket and the transformer, pre-drilled holes are generally provided on the bracket. However, due to factors such as construction errors, when placing the transformer on the bracket, it is easy to occur that the pre-drilled holes on the bracket are not aligned with the pre-drilled holes on the transformer. In response to this situation, it is usually necessary for workers to re-move the transformer or re-drill holes on the bracket, reducing the installation efficiency of the transformer; when the bracket supports the transformer, the bracket will block the bottom of the transformer, which is not conducive to the staff to detect whether there is an oil leakage problem in the blocked part of the transformer and affects the heat dissipation of the transformer; and the horizontal part of the bracket is prone to water accumulation. Based on this, the present application proposes a transformer bracket for a power plant. Summary of the Invention

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention provides a support for a power plant transformer, including a support body 1. Positioning grooves 2 are provided on both sides of the support body 1. When the support is in use, the positioning grooves 2 can be used to preliminarily position the power plant transformer. When the power plant transformer is placed on the support, it only needs to meet the requirement that the pre-drilled holes of the power plant transformer are located above the positioning grooves 2, reducing the difficulty of placing the power plant transformer and thus improving the installation efficiency of the power plant transformer.

[0027] Two moving blocks 5 are connected by a lead screw structure inside the inner cavity of the positioning groove 2. The lead screw structure includes a ball screw 4 movably connected to the inner cavity of the positioning groove 2. One end of the ball screw 4 extends to the outside of the support. A rotating handle is fixedly connected to one end of the ball screw 4. The staff can drive the ball screw 4 to rotate by using the rotating handle. Two ball nuts are threadedly connected to the outer circle of the ball screw 4. The moving block 5 is fixedly connected to the ball nut. The distance between the two moving blocks 5 is the same as the positions of the two pre-installation holes on both sides of the transformer. Through the setting of the ball screw 4, the rotation of the ball screw 4 can change the position of the ball nut threadedly connected thereto, and the ball nut can move in the direction where the ball screw 4 is located. When the ball nut moves, it can drive the moving block 5 fixedly connected thereto to move.

[0028] Support grooves 3 are provided on both sides of the inner cavity of the positioning groove 2. The moving block 5 is of a convex structure. The upper end of the moving block 5 is adapted to the positioning groove 2, and the lower end of the moving block 5 is movably connected to the inner cavity of the support groove 3. Through the setting of the support groove 3, the moving block 5 can be supported to improve the stability of the moving block 5.

[0029] A pre-drilled hole 8 is provided in the middle of the moving block 5. The pre-drilled hole 8 is adapted to the pre-installation hole opened on the power plant transformer. When the pre-drilled hole 8 overlaps with the pre-installation hole, tools such as bolts can be used to fix the power plant transformer to the support. The pre-drilled hole 8 is cross-shaped. Through the setting of the pre-drilled hole 8, the alignment speed between the pre-drilled hole 8 and the installation hole can be improved.

[0030] As can be seen from the above description, when the support is in use, when the pre-installation hole of the transformer and the pre-drilled hole 8 are in a staggered state, the staff can adjust the position of the pre-drilled hole 8 by rotating the ball screw 4, so that the pre-drilled hole 8 can be aligned with the pre-installation hole, facilitating the installation of the transformer.

[0031] The moving block 5 is provided with a leakage detection structure. The leakage detection structure includes a sealing cylinder 10. At the top of the inner cavity of the sealing cylinder 10, a test pen 7 is fixedly connected. The test pen tip of the test pen 7 is flush with the top of the moving block 5. The xenon tube of the test pen 7 is located inside the inner cavity of the sealing cylinder 10. At the bottom of the inner cavity of the sealing cylinder 10, a light sensor 11 is fixedly connected. Through the setting of the leakage detection structure, when this bracket is fixed to the power plant transformer, the test pen tip of the test pen 7 contacts the transformer. When the outer shell of the transformer is electrified, the test pen 7 detects the current, the xenon tube of the test pen 7 emits light, and the light sensor 11 can detect the light. According to the detection result of the light sensor 11, it can be judged whether the transformer has a leakage phenomenon.

[0032] A controller 9 is provided on the bracket body 1. An alarm 21 is provided on one side of the bracket body 1. The controller 9 is connected to the alarm 21. The light sensor 11 uploads the detection result to the controller 9. The controller 9 controls the alarm 21 to work according to the detection result. The alarm 21 can give an early warning, making people stay away from this transformer. The light sensor 11 and the alarm 21 can transmit signals to the controller 9 through wireless communication technology. The controller 9 can use wireless communication technology to upload the detection result to the cloud or the staff.

[0033] Through the setting of the leakage detection structure, this bracket has the functions of leakage detection and early warning, reducing the probability of electric shock of the staff due to transformer leakage.

[0034] The bracket body 1 includes a strengthening part 12 and a heat dissipation part 13. The outer surface of the strengthening part 12 is wrapped with the heat dissipation part 13. The heat dissipation part 13 is evenly provided with heat dissipation holes. At the top of the heat dissipation part 13, diversion holes are evenly fixedly connected. The diversion holes are inclined. The lower end of the diversion hole is located on the side of the heat dissipation part 13 away from the strengthening part 12. Through the setting of the heat dissipation part 13, when this bracket is in normal use, it can improve the heat dissipation effect of the contact part between the bracket and the transformer, and the water falling on the bracket can be discharged through the heat dissipation holes and the diversion holes, avoiding water accumulation on the bracket. A hydrophobic coating is applied to the top of the heat dissipation part 13 and the inner wall of the diversion hole. Through the setting of the hydrophobic coating, the drainage speed can be accelerated. The material of the bracket body 1 can be selected according to needs and is not limited here.

[0035] An oil leakage detection structure 6 is embedded on the heat dissipation part 13. The oil leakage detection structure 6 includes a shaping tube 14. The shaping tube 14 is provided on both the top and the side wall of the heat dissipation part 13. The shaping tube 14 is evenly provided with oil leakage holes. When the transformer leaks oil, the oil liquid can enter the inner cavity of the shaping tube 14 through the heat dissipation holes and the oil leakage holes.

[0036] On one side of the inner cavity of the shaping tube 14, oil leakage detection lines 18 are evenly provided. The outer surface of the oil leakage detection lines 18 is wrapped with an oil absorption pad. The oil absorption pad can adsorb the oil liquid leaked from the transformer. The material of the oil absorption pad can be selected according to needs and is not limited here.

[0037] Both ends of the oil leakage detection line 18 are fixedly connected with elastic lines 16. The elastic lines 16 are fixedly connected with the inner wall of the shaping tube 14 through fixing blocks 15. Through the arrangement of the elastic lines 16, the position of the oil leakage detection line 18 can be changed. A limiting ring 22 is arranged on the outer ring of the middle part of the oil leakage detection line 18. A pressure sensor 19 is fixedly connected to the bottom of the inner cavity of the limiting ring 22, and pressure sensor units of the pressure sensor 19 are evenly arranged on the inner wall of the limiting ring 22. Through the arrangement of the pressure sensor 19, when the oil leakage detection line 18 adsorbs oil, the pressing force of the oil leakage detection line 18 on the pressure sensor units changes, and the pressure sensor 19 detects the change amount of the pressure.

[0038] On the other side of the inner cavity of the shaping tube 14, a signal transmission main line 17 is arranged. The pressure sensor 19 is connected with the signal transmission main line 17 through a signal transmission branch line 20. The signal transmission main line 17 is connected with the controller 9. The pressure change amount detected by the pressure sensor 19 can be transmitted to the controller 9 through the signal transmission branch line 20 and the signal transmission main line 17. The controller 9 can judge whether the transformer leaks oil according to the detection result. The alarm 21 can realize oil leakage early warning. The controller 9 can upload the oil leakage early warning to the cloud or the staff, which is beneficial for the staff to detect whether there is an oil leakage problem in the shielded part of the transformer.

[0039] All the electrical components involved in this application are existing technologies. Those skilled in the art understand their connection methods. Through those skilled in the art, all the electrical components in this application are connected to their adapted power supplies through wires, and a suitable controller is selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, please refer to the following description. The electrical components are electrically connected in the order of their respective working sequences. Their detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and no further description of electrical control will be given.

[0040] In summary: When the power plant transformer support is in use, the transformer is positioned by using the positioning groove. When the pre-installation holes of the power plant transformer are located above the positioning groove, the power plant transformer can be placed on the support body 1. When the pre-opening 8 and the pre-installation hole are in a staggered state, the staff rotates the ball screw 4. When the ball screw 4 rotates, the ball nut threadedly connected with it moves in the direction of the ball screw 4. When the ball nut moves, it drives the moving block 5 fixedly connected with it to move until the pre-opening 8 on the moving block 5 is aligned with the pre-installation hole on the transformer, omitting the operation of repeatedly adjusting the position of the transformer and improving the convenience and efficiency of transformer installation.

[0041] During the use of the bracket, the live detection structure is utilized to detect the live condition of the transformer shell in real time. When the transformer shell is live, the xenon tube of the electroscope 7 emits light. The photosensor 11 detects the light and uploads the detection result to the controller 9. The controller 9 controls the alarm 21 to work according to the detection result. The alarm 21 gives an early warning, reducing the probability of electric shock to the staff. And the controller uploads the result to the staff, facilitating the staff to detect the transformer in time.

[0042] During the use of the bracket, the oil leakage detection structure can be used to judge whether there is an oil leakage problem in the part of the power plant transformer blocked by the bracket. When there is an oil leakage, the oil liquid enters the inner cavity of the shaping tube 14 through the heat dissipation holes and the oil leakage holes. The oil liquid in the shaping tube 14 is adsorbed by the oil leakage detection line 18, and the oil leakage detection line 18 becomes heavier. The pressing force of the oil leakage detection line 18 on the pressure sensor 19 changes. The controller can judge whether there is an oil leakage according to the pressure change amount detected by the pressure sensor 19.

[0043] When the bracket is in use, the heat dissipation part 13 facilitates drainage and heat dissipation.
