Description

Technical Field

[0001] This invention relates to the field of power distribution equipment, and more particularly to a reinforcement structure for the installation of power distribution equipment. Background Technology

[0002] Transformers come in various types, but their basic structure is largely the same, mainly consisting of the transformer body and insulating bushings. The transformer body can be divided into the internal core and windings, and the external oil tank and accessories. The windings and core are assembled and fixed in an oil tank filled with insulating oil; the outer walls of the oil tank are reinforced with iron to increase its rigidity; external components such as oil conservators and radiators are attached to the tank. The transformer body is usually floating on a concrete platform or rails. If no anchoring measures are taken or the anchoring strength is insufficient, the transformer body often slips, falls, or even overturns during earthquakes. This can cause the porcelain bushings on the top of the transformer to crack or even break due to the conductors, or become misaligned with the flanges; accessories such as radiators and oil conservators may be indirectly or directly damaged by impact, leading to oil leaks; and broken conductors may cause internal transformer malfunctions and fires.

[0003] The invention patent “A reinforcement method for improving the seismic performance of large transformers and a large transformer” (application number CN201711093431.7) discloses a bushing reinforcement method, which can support and protect the bushing to a certain extent and improve its seismic performance. However, it cannot reduce the vibration of the transformer body. When the transformer body vibrates violently, the bushing may still break and the transformer body may also be damaged. Summary of the Invention

[0004] This invention provides a reinforcement structure for the installation of power distribution equipment, which solves the problem of the lack of a device for vibration reduction of the transformer body in the prior art.

[0005] A reinforcement structure for installing power distribution equipment includes two damping bases located at the bottom of a transformer body and four mounting columns. Each damping base includes a rectangular base body with a closed cavity containing a piston capable of vertical movement. The base body also has two gas channels connecting the cavity to the outside; one gas channel is located above the piston, and the other below it. A piston rod is connected to the piston and is connected to the transformer body. The four mounting columns are located on the four sides of the transformer body. Sliding sleeves are slidably fitted onto each mounting column. Damping rods are positioned between the sliding sleeves and the transformer body, with one end connected to the transformer body and the other end connected to the sliding sleeve. In use, two damping bases are fixedly installed on the mounting surface, and the transformer is placed on the two damping bases. When an earthquake occurs, the mounting surface vibrates, and the piston, under the action of air pressure on both sides, weakens the vertical vibration, thus reducing the vibration transmitted to the transformer. The mounting column is fixed on the mounting surface and connected to the transformer through the damping rod, which weakens the horizontal vibration. The damping bases and damping rods work together to reduce vibration and prevent damage to the transformer.

[0006] Furthermore, a pad is provided above the damping base, and the pad is fixedly connected to the transformer body. A groove is provided on the lower surface of the pad, and a crossbar is provided in the groove. A rod sleeve is slidably sleeved on the crossbar, and the piston rod is fixedly connected to the rod sleeve. The rod sleeve is slidably sleeved on the crossbar, so that the transformer can move relative to the damping base along the direction of the crossbar, and the damping rod can reduce vibration in this direction.

[0007] Furthermore, it also includes a height limiting frame, located above the transformer body. A vertical rod is fixedly connected to the height limiting frame and to the base body. The length of the vertical rod is greater than the sum of the height of the transformer body and the height of the pad. Because the length of the vertical rod is greater than the sum of the height of the transformer body and the height of the pad, the height limiting frame does not contact the transformer body under normal circumstances, and there is a certain gap between the height limiting frame and the top of the transformer body. When the transformer vibrates, the height limiting frame can limit the vertical vibration of the transformer.

[0008] Furthermore, it also includes a lateral limiting frame, within which the transformer body is located. The length and width of the lateral limiting frame are greater than the length and width of the transformer body, respectively. The lateral limiting frame is connected to the mounting column sequentially via a first connecting rod and a sliding sleeve. The lateral limiting frame is slightly larger than the cross-section of the transformer body and does not normally contact the transformer body. However, it can limit the position of the transformer body when it vibrates. A first connecting rod is fixedly connected to the lateral limiting frame, and a sliding sleeve is fixedly connected to the first connecting rod, with the sliding sleeve slidably fitted onto the mounting column.

[0009] Furthermore, a rubber buffer strip is provided on the bottom surface of the height limiting frame.

[0010] Furthermore, a rubber buffer strip is provided on the inner side of the lateral limiting frame.

[0011] Furthermore, the pad includes an upper support and a lower support, which are slidably connected. The upper surface of the lower support has an I-shaped guide strip, and the bottom surface of the upper support has a groove that mates with the I-shaped guide strip. The I-shaped guide strip is located within the groove and slidably engages with it. The I-shaped guide strip is horizontal and perpendicular to the crossbar. The transformer body is fixedly connected to the upper support, and the groove is located on the bottom surface of the lower support. The I-shaped guide strip, in conjunction with the crossbar, enables the transformer body to vibrate relative to the damping base in any horizontal direction, thereby allowing the damping rod to function and reduce lateral vibration.

[0012] Furthermore, a clamp is fitted onto the transformer bushing, and the clamp is fixedly connected to the transformer body via a second connecting rod. The clamp and the second connecting rod reinforce the bushing and prevent it from being damaged by vibration.

[0013] As can be seen from the above technical solutions, the present invention has the following advantages:

[0014] In use, two damping bases are fixedly installed on the mounting plane, and the transformer is placed on the two damping bases. When an earthquake occurs, the mounting plane vibrates, and the piston, under the action of air pressure on both sides, weakens the vertical vibration, thus reducing the vibration transmitted to the transformer. The mounting column is connected to the transformer through a damping rod, which weakens the horizontal vibration. The damping bases and damping rods work together to reduce vibration and prevent damage to the transformer. Attached Figure Description

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] Example 1

[0023] like Figure 1-4As shown, a reinforcement structure for installing power distribution equipment includes two damping bases located at the bottom of a transformer body 1 and four mounting columns 7. The damping base includes a cuboid base body 2 with a closed cavity 3. A piston 4 capable of moving up and down is located inside the cavity 3. The base body 2 has two gas channels 5 that connect the cavity 3 to the outside. One gas channel 5 is located above the piston 4 and the other is located below the piston 4. A piston rod 6 is connected to the piston 4 and is connected to the transformer body 1. The four mounting columns 7 are located on the four sides of the transformer body 1. A sliding sleeve 8 is connected to the mounting column 7. A damping rod 9 is provided between the sliding sleeve 8 and the transformer body 1. One end of the damping rod 9 is connected to the transformer body 1, and the other end is connected to the sliding sleeve 8. In use, two damping bases are fixedly installed on the mounting surface, and the transformer is placed on the two damping bases. When an earthquake occurs, the mounting surface vibrates. The piston 4, under the action of air pressure on both sides, weakens the vertical vibration, thus reducing the vibration transmitted to the transformer. The mounting column 7 is fixed to the mounting surface and connected to the transformer through the damping rod 9, weakening the horizontal vibration. The damping bases and damping rod 9 work together to weaken vibration and prevent damage to the transformer. A pad 10 is provided above the damping base, and the pad 10 is fixedly connected to the transformer body 1. A groove is provided on the lower surface of the pad 10, and a crossbar 11 is provided in the groove. A rod sleeve 12 is connected to the crossbar 11 by a sliding sleeve 8. The piston rod 6 is fixedly connected to the rod sleeve 12. The sliding sleeve 8 of the rod sleeve 12 is connected to the crossbar 11, allowing the transformer to move relative to the damping base along the direction of the crossbar 11, and the damping rod 9 can weaken the vibration in this direction. The system also includes a height limiting frame, located above the transformer body 1. A vertical rod is fixedly connected to the height limiting frame and to the base body 2. The length of the vertical rod is greater than the sum of the height of the transformer body 1 and the height of the pad 10. Because the length of the vertical rod is greater than the sum of the height of the transformer body 1 and the height of the pad 10, the height limiting frame does not normally contact the transformer body 1, and there is a certain gap between the height limiting frame and the top of the transformer body 1. When the transformer vibrates, the height limiting frame can limit the vertical vibration of the transformer. The system also includes a horizontal limiting frame 15, within which the transformer body 1 is located. The length and width of the horizontal limiting frame 15 are greater than the length and width of the transformer body 1, respectively. The horizontal limiting frame 15 is connected to the mounting column 7 sequentially via a first connecting rod 16 and a sliding sleeve 8. The horizontal limiting frame 15 is slightly larger than the cross-section of the transformer body 1 and does not normally contact the transformer body 1. When the transformer body 1 vibrates, it can limit the position of the transformer body 1. A first connecting rod 16 is fixedly connected to the horizontal limiting frame 15, and a sliding sleeve 8 is fixedly connected to the first connecting rod 16. The sliding sleeve 8 is connected to the mounting column 7. A rubber buffer strip is provided on the bottom surface of the height limiting frame.A rubber buffer strip is provided on the inner side of the transverse limiting frame 15. The pad block 10 includes an upper support part 13 and a lower support part 17, which are slidably connected. The upper surface of the lower support part 17 is provided with an I-shaped guide strip 18, and the bottom surface of the upper support part 13 is provided with a groove that cooperates with the I-shaped guide strip 18. The I-shaped guide strip 18 is located in the groove and is slidably engaged with the groove. The I-shaped guide strip 18 is horizontal and perpendicular to the crossbar 11. The transformer body 1 is fixedly connected to the upper support part 13, and the groove is provided on the bottom surface of the lower support part 17. The I-shaped guide strip 18 cooperates with the crossbar 11 to realize the vibration of the transformer body 1 relative to the damping base in any horizontal direction, thereby enabling the damping rod 9 to play its role and reduce transverse vibration. A sleeve 14 is fitted on the transformer bushing 19, and the sleeve 14 is fixedly connected to the transformer body 1 through a second connecting rod. The sleeve 14 and the second connecting rod reinforce the bushing to prevent damage to the bushing during vibration.
