Description

Technical Field

[0001] This utility model relates to the field of busbar connector technology, specifically to a seismic-resistant busbar connector for substations. Background Technology

[0002] Busbar trunking is an enclosed metal structure made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. In indoor low-voltage power transmission trunk line projects, it is increasingly replacing electrical wires and cables. Especially in power facilities such as substations, busbar trunking is a key component for power transmission, undertaking the important task of transmitting electrical energy from power supply equipment such as transformers to various distribution cabinets and electrical equipment. Its operational stability directly affects the normal power supply of the substation.

[0003] However, most existing busbar connectors are fixed by rigid components and do not have shock resistance. When subjected to bumps or vibrations, the internal structure may be damaged, and the internal fixing screws may loosen, resulting in poor contact at the busbar connection points, affecting the stability of power transmission, and even causing faults such as short circuits. To address this, we provide a shock-resistant busbar connector for substations. Utility Model Content

[0004] The purpose of this invention is to provide a seismic-resistant busbar connector for substations to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A seismic-resistant busbar connector for substations includes a busbar trough one, a busbar trough two is provided on the right side of the busbar trough one, a connector is detachably connected between the busbar trough one and the busbar trough two, and conductive sheets are provided inside the busbar trough one and the busbar trough two.

[0006] Both ends of the busbar trough 1 and busbar trough 2 are provided with connection units, and the outer surfaces of the busbar trough 1 and busbar trough 2 are provided with anti-seismic units.

[0007] The seismic unit includes a fixed frame that is fixedly installed at the middle position on the outer surface of busbar duct one and busbar duct two.

[0008] A further improvement of the present invention is that: limiting grooves are provided on the four sides of the busbar trough one and busbar trough two, and a movable frame one is movably sleeved at the left end of the outer surface of the busbar trough one and busbar trough two, and the limiting grooves can limit the position of the movable frame one and movable frame two.

[0009] A further improvement of the present invention is that: a movable frame 2 is movably sleeved at the right end of the outer surface of busbar trough 1 and busbar trough 2, and sliders are fixedly installed on the inner sides of both movable frame 1 and movable frame 2, and the sliders are slidably connected inside the limiting groove.

[0010] A further improvement of this utility model is that: a damper is fixedly installed on all four sides of the inner side of the movable frame, and the other end of the damper is fixedly installed on the left side of the fixed frame. An elastic wire is sleeved on the outer surface of the damper. The damper and the elastic wire work together to effectively absorb and buffer vibration energy, reducing the impact of vibration on the busbar and connection parts.

[0011] A further improvement of the present invention is that: a damper is fixedly installed on all four sides of the inner side of the movable frame, the other end of the damper is fixedly installed on the right side of the fixed frame, and an elastic wire is sleeved on the outer surface of the damper.

[0012] A further improvement of the present invention is that the connecting unit includes locking holes on the four sides of the first and second movable frames, and connecting vertical plates are fixedly installed on the front and rear sides of the connector on the left and right sides, and through holes are opened at the upper and lower ends of the connecting vertical plates.

[0013] A further improvement of this utility model is that: the internal thread of the through hole is connected to a bolt, and the other end of the bolt passes through the inside of the locking hole.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a seismic-resistant busbar connector for substations. The connector is equipped with a seismic-resistant unit. When subjected to vibration, the first and second moving frames will move along the limiting groove, squeezing or stretching the damper and elastic wire. The damper generates damping force to consume vibration energy, and the elastic wire generates elastic force to buffer the movement. The two work together to effectively absorb and buffer vibration energy, reduce the impact of vibration on the busbar and connection parts, avoid damage to the internal structure due to vibration, and prevent the fixing screws from loosening.

[0015] 2. This utility model provides a shock-resistant busbar connector for substations. By using a connection unit, a stable connection between the busbar and the connector is achieved. Combined with the shock-resistant unit's buffering effect on vibration, good contact at the busbar connection point can be ensured, thereby ensuring the stability of power transmission and reducing the probability of short circuits and other faults caused by connection problems.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figure 1-5 As shown, this utility model provides a seismic-resistant busbar connector for substations, including a busbar slab 1, a busbar slab 2 on the right side of the busbar slab 1, a connector 3 detachably connected between the busbar slab 1 and the busbar slab 2, conductive sheets 4 inside the busbar slab 1 and the busbar slab 2, connecting units at both ends of the busbar slab 1 and the busbar slab 2, and seismic-resistant units on the outer surfaces of the busbar slab 1 and the busbar slab 2. The connecting unit includes locking holes 16 on the periphery of the movable frames 13 and 14. Connecting vertical plates 31 are fixedly installed on the front and rear sides of the connector 3 on the left and right sides. Through holes 32 are opened at the upper and lower ends of the connecting vertical plates 31. Bolts 33 are threaded into the through holes 32, and the other end of the bolts 33 passes through the interior of the locking holes 16.

[0020] Furthermore, by placing the connector 3 between the busbar trough 1 and the busbar trough 2, the connecting vertical plates 31 on the front, back, left and right sides of the connector 3 correspond to the moving frame 14 on the right end of the busbar trough 1 and the moving frame 13 on the left end of the busbar trough 2, respectively. Then, the bolt 33 is passed through the through hole 32 on the connecting vertical plate 31 and screwed into the locking hole 16 on the moving frame, thereby achieving a fixed connection between the busbar trough 1, the busbar trough 2 and the connector 3. At this time, the conductive plates 4 inside the busbar trough 1 and the busbar trough 2 are connected for power transmission through the connector 3.

[0021] Example 2 like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the seismic unit includes a fixed frame 11 fixedly installed at the middle position of the outer surface of busbar duct 1 and busbar duct 2. Limiting grooves 12 are provided on the four sides of the shell of busbar duct 1 and busbar duct 2. A movable frame 13 is movably sleeved at the left end of the outer surface of busbar duct 1 and busbar duct 2. A movable frame 24 is movably sleeved at the right end of the outer surface of busbar duct 1 and busbar duct 2. The inner sides of movable frame 13 and movable frame 24 are... Slider 15 is fixedly installed on all four sides, and slider 15 is slidably connected inside the limiting groove 12. Damper 17 is fixedly installed on all four sides of the inner side of the moving frame 13. The other end of damper 17 is fixedly installed on the left side of the fixed frame 11. Elastic wire 18 is sleeved on the outer surface of damper 17. Damper 29 is fixedly installed on all four sides of the inner side of the moving frame 14. The other end of damper 29 is fixedly installed on the right side of the fixed frame 11. Elastic wire 210 is sleeved on the outer surface of damper 29.

[0022] Furthermore, when vibration occurs, it is transmitted to busbar 1 and busbar 2. Since the first movable frame 13 and the second movable frame 14 are slidably connected to the limiting groove 12 of the busbar housing through the slider 15, the first movable frame 13 and the second movable frame 14 will move along the limiting groove 12 under the action of vibration. For the first movable frame 13, when it moves towards the fixed frame 11, it will squeeze the damper 17. The damper 17 will generate damping force to consume vibration energy. At the same time, the elastic wire 18 sleeved on the outer surface of the damper 17 will be compressed and generate elastic force. This elastic force will buffer the movement of the first movable frame 13. When the vibration direction is opposite and the first movable frame 13 moves away from the fixed frame 11, the elastic wire 18 will stretch and generate tension. Combined with the damping effect of the damper 17, the movement of the first movable frame 13 will be further slowed down, thereby reducing the impact of vibration on the busbar 1.

[0023] The working principle of the seismic-resistant busbar connector used in this substation will be explained in detail below.

[0024] like Figure 1-5As shown, during use, connector 3 is first placed between busbar 1 and busbar 2, so that the connecting vertical plates 31 on the front, back, left, and right sides of connector 3 correspond to the moving frame 14 on the right end of busbar 1 and the moving frame 13 on the left end of busbar 2, respectively. Then, bolts 33 are passed through the through holes 32 on the connecting vertical plates 31 and screwed into the locking holes 16 on the moving frames, thereby achieving a fixed connection between busbar 1, busbar 2 and connector 3. At this time, the conductive plates 4 inside busbar 1 and busbar 2 are connected for power transmission through connector 3. When vibration occurs, the vibration will be transmitted to busbar 1 and busbar 2. Since the moving frame 13 and the moving frame 14 are slidably connected to the busbar housing by the slider 15, Within the limiting groove 12, the moving frame 13 and the moving frame 2 14 will move along the limiting groove 12 under the action of vibration. For the moving frame 13, when it moves towards the fixed frame 11, it will squeeze the damper 17. The damper 17 will generate damping force to consume vibration energy. At the same time, the elastic wire 18 sleeved on the outer surface of the damper 17 will be compressed and generate elastic force. This elastic force will buffer the movement of the moving frame 13. When the vibration direction is opposite and the moving frame 13 moves away from the fixed frame 11, the elastic wire 18 will stretch and generate tension. Combined with the damping effect of the damper 17, the movement of the moving frame 13 will be further slowed down, thereby reducing the impact of vibration on the busbar 1.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
