Description

Technical Field

[0001] This utility model belongs to the field of busbar technology, specifically a substation busbar connection, fastening and anti-loosening structure. Background Technology

[0002] Busbars are key conductive components in power systems used for the collection, distribution, and transmission of electrical energy. Their working principle is based on the conduction characteristics of current and the collection-distribution logic of electrical energy. The core is to achieve efficient transmission of large currents through low-resistance conductors and to ensure the stable flow of electrical energy between different devices through reasonable connection and support structures. The busbars in substations are usually not a single complete conductor, but are divided into multiple segments according to power distribution needs, equipment layout, or expansion needs. The core purpose of the connection is to "splice" these segments into a continuous conductive whole to ensure that the current can flow smoothly between the segments.

[0003] Meanwhile, a busbar that is easy to install is disclosed (announcement number 202223042423.9), including a busbar, with support blocks fixedly installed on the left and right sides of the front and rear of the busbar, an inner connecting block fixedly connected to the right side of the right support block, and slots opened on the upper and lower surfaces of the inner connecting block, and two outer connecting blocks fixedly installed on the left side of the left support block, with support springs fixedly connected to the inner cavities of the two outer connecting blocks; The aforementioned easy-to-install busbar only has an auxiliary busbar connection structure during use, lacking the main components for connecting two busbars. Furthermore, in the existing technology, busbars are generally connected by directly fixing the connector to the busbar with bolts, but this lacks an effective fastening and protection structure. Under the influence of the external environment, it is prone to loosening, affecting the tightness of the busbar connection.

[0004] Therefore, a substation busbar connection fastening and anti-loosening structure is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a substation busbar connection fastening and anti-loosening structure. It features a structural design that uses the slots, grooves, return springs, and top plate on the limiting block to limit and elastically fasten the busbars. At the same time, through the positioning component, the busbar splicing is completed using the mounting holes and positioning posts on the fixing plate, achieving precise positioning and firm fastening, and ensuring stable connection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a substation busbar connection fastening and anti-loosening structure, comprising a connector and a busbar, wherein the busbar is connected to both ends of the connector, and limit blocks are symmetrically arranged at both ends of the connector. The limit blocks are evenly provided with slots, and grooves are provided within the slots. A return spring is installed in the inner cavity of the groove, and one end of the return spring is connected to a top plate. A positioning component is provided at the middle position of the upper and lower sides of the connector, and the positioning component includes a positioning frame, a rotating handle, a lead screw, a moving block, a connecting seat, and a fixing plate. Heat dissipation vents are provided on both sides of the connector.

[0007] Preferably, the card slots are equidistant, and the limiting block is in contact with the inner wall of the card slot.

[0008] Preferably, the two ends of the return spring abut against the top plate and the groove, and the groove fits against the outer wall of the return spring.

[0009] Preferably, the positioning frame is symmetrically arranged on the upper and lower sides of the connector, the lead screw, the rotating handle and the moving block are symmetrically arranged inside the positioning frame, one end of the moving block is fixed to the connecting seat, and one end of the fixing plate is fixed to the connecting seat.

[0010] Preferably, the movable block is threaded onto a lead screw, and one end of the lead screw is connected to a rotary handle.

[0011] Preferably, the connection between the positioning frame and the connector is provided with a guide groove that matches the moving block, and the moving block passes through the guide groove and is fixed to the connector.

[0012] Preferably, the fixing plate is provided in multiple sets and the number of busbars is matched with the number of busbars in the busbar row. The opposite side of the fixing plate is provided with corresponding mounting holes and positioning posts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the design of the slot, groove, return spring and top plate on the limiting block, can play a certain limiting and elastic fastening role for the busbar of the busbar. When the busbar is subjected to external forces such as vibration, the return spring can buffer the external force through its own elastic deformation, reduce the loosening caused by vibration and maintain the stability of the connection.

[0014] 2. This utility model drives the lead screw to rotate by rotating the handle, which in turn moves the moving block on the lead screw, thereby moving the connecting seat and the fixing plate. This allows the mounting holes and positioning pins on the fixing plate to connect the busbars of the two sets of wire bars, realizing the splicing of the busbars and facilitating the precise positioning and secure fastening of the busbars.

[0017] 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.

[0018] The following describes an embodiment of this utility model based on its overall structure.

[0019] like Figures 1 to 5 As shown, this utility model provides a substation busbar connection fastening and anti-loosening structure, including a connector 1 and a busbar 2. The busbar 2 is connected to both ends of the connector 1. Limiting blocks 3 are symmetrically arranged at both ends of the connector 1 to limit the lateral displacement of the busbar 2. The limiting blocks 3 are evenly provided with slots 4. The end of the busbar 2 can be inserted into the slot 4 to achieve initial positioning. The slot 4 is provided with a groove 5. The inner cavity of the groove 5 is equipped with a return spring 6. One end of the return spring 6 is connected to a top plate 7. When the busbar 2 is inserted into the slot 4, the top plate 7 contacts the surface of the busbar 2 and compresses the return spring 6. A positioning component 8 is provided at the middle position of the upper and lower sides of the connector 1. The positioning component 8 includes a positioning frame 81, a rotating handle 82, a lead screw 83, a moving block 84, a connecting seat 85, and a fixing plate 86. Heat dissipation vents 9 are provided on both sides of the connector 1 to dissipate the heat generated by the busbar 2 during operation.

[0020] In this embodiment, the slots 4 are equidistantly arranged, the limiting block 3 fits against the inner wall of the slot 4, and the spacing between adjacent slots 4 matches the spacing between each busbar in the busbar 2, ensuring that each busbar in the busbar 2 can be embedded in a slot 4.

[0021] The two ends of the return spring 6 abut against the top plate 7 and the groove 5. The groove 5 fits against the outer wall of the return spring 6 and is cylindrical, which restricts the return spring 6 from lateral displacement when subjected to force.

[0022] Positioning frames 81 are symmetrically arranged on the upper and lower sides of connector 1. Screw 83, rotating handle 82 and moving block 84 are symmetrically arranged inside positioning frames 81. One end of moving block 84 is fixed to connecting seat 85, and one end of fixing plate 86 is fixed to connecting seat 85. The upper fixing plate 86 and the lower fixing plate 86 cooperate to clamp and fix a single busbar, so that multiple sets of fixing plates 86 can fix each busbar.

[0023] The movable block 84 is threadedly connected to the lead screw 83. One end of the lead screw 83 is connected to the rotating handle 82. The center of the movable block 84 has an internal thread hole that matches the external thread of the lead screw 83. The movable block 84 is sleeved on the lead screw 83 through thread engagement.

[0024] The connection between the positioning frame 81 and the connector 1 is provided with a guide groove that matches the moving block 84. The moving block 84 passes through the guide groove and is fixed to the connecting seat 85. The cross-sectional shape of the guide groove matches the cross-sectional shape of the moving block 84. The guide groove restricts the moving block 84 to rotate synchronously with the lead screw 83, ensuring that the moving block 84 only moves linearly along the axial direction of the lead screw 83.

[0025] The fixing plates 86 are provided in multiple sets, which match the number of busbars in the busbar row 2. The opposite side of the fixing plates 86 is provided with corresponding mounting holes 87 and positioning posts 88. Each set of fixing plates 86 corresponds to one busbar. The inner sides of the upper and lower opposing fixing plates 86 (i.e. the sides that are close to each other) are respectively machined with mounting holes 87 and positioning posts 88. The positioning posts 88 on one side of the fixing plate 86 correspond in position and match in size with the mounting holes 87 on the other side of the fixing plate 86. When the fixing plates 86 clamp the busbar row 2, the positioning posts 88 are inserted into the mounting holes 87 to achieve precise positioning.

[0026] The working principle and process of a substation busbar connection fastening and anti-loosening structure: The busbar 2 is connected to both ends of the connector 1. At the same time, the busbar of the busbar 2 is inserted into the corresponding slot 4 on the limiting block 3, so that the top plate 7 contacts the busbar and drives the return spring 6 to compress. The rebound force of the return spring 6, together with the slot 4, elastically fastens the busbar. When the busbar 2 is subjected to external forces such as vibration, the return spring 6 can buffer the external force through its own elastic deformation, reduce loosening caused by vibration, and maintain the stability of the connection. After the busbar 2 is fixed, the screw is driven by rotating the handle 82. Rotation of 83 causes the moving block 84 to move on the lead screw 83, which in turn drives the connecting seat 85 and the fixing plate 86 to move, so that the mounting holes 87 and positioning posts 88 on the fixing plate 86 connect the busbars of the two sets of busbars. The fixing plate 86 is made of conductive material to realize the splicing of the busbar 2, which facilitates the precise positioning and firm fastening of the busbar 2. During the transmission of electrical energy by the busbar 2, the current will generate heat. The heat dissipation vents 9 on both sides of the connector 1 allow air to flow around the connector 1, dissipating the heat generated by the busbar 2 and maintaining the working temperature of the busbar 2 within a reasonable range.
