Description

Technical Field

[0001] The utility model belongs to the technical field of busbar transmission equipment, and in particular relates to a power busbar transmission equipment. Background Art

[0002] Busbar refers to the metal conductor line used to transmit electric energy in power equipment, usually made of excellent conductive materials such as copper or aluminum, and used to transmit, distribute or concentrate electricity inside power equipment. Bus duct is a device used to transmit large currents, usually made of conductive materials. The main function of bus duct is to carry cables, combine cables into a whole, reduce resistance and voltage drop when transmitting electric energy over long distances, and ensure stable transmission of current. Bus duct is widely used in power plants, substations, industrial and mining enterprises, urban rail transit and other fields, and has become an indispensable distribution equipment in power systems.

[0003] The bus duct is composed of a conductor bus, insulating materials, supporting fixtures, and wiring parts. During outdoor installation, the bus duct sections need to be connected and fixed through connectors, and then the shell is installed accordingly to protect the conductor and improve the appearance.

[0004] However, when actually installing the shell, the top cover usually needs to be fixed with bolt nuts or screws and metal cable ties. This fixing method is inefficient. Since it is installed section by section, it will lead to the need to dismantle multiple sections of the shell and inspect the internal components separately during the installation and subsequent maintenance and inspection, which consumes a lot of time and reduces the efficiency of the inspection.

[0005] In view of this, the present utility model is proposed. Utility Model Content

The inner walls of the plurality of movable grooves 6 are slidably and elastically fitted with plug-in blocks 7 that cooperate with the snap-fit ​​grooves 4. A linkage rod 8 extending to the outside of the top cover 5 is fixedly connected to one side of the plug-in block 7, and one end of the linkage rod 8 is fixedly connected to a pulling plate 9 located on both sides of the top cover 5. Two reinforcement components 10 that cooperate with the pulling plate 9 are installed on both sides of the top cover 5, and a fixing mechanism 11 is installed on the lower side of the two bases 3.

[0032] One aspect of the application of this embodiment is: when in use, firstly, two busbar cores 1 need to be connected through a connector 2, and then a base 3 is installed on the outside of the two busbar cores 1 to fix the connection, and the two bases 3 are abutted against each other to achieve sealing;

[0033] Then, pull the two pulling plates 9 with both hands, and pull the plug-in block 7 through the linkage rod 8 to hide in the movable groove 6. Cover the top cover 5 on the base 3. When the pressing is completed, release the pulling plate 9. A spring is provided between the plug-in block 7 and the movable groove 6. Under the action of the spring, the plug-in block 7 is pressed so that the plug-in block 7 is inserted into the locking groove 4, so that the top cover 5 and the base 3 are connected. Then, the pulling plate 9 is reinforced by the reinforcement component 10 to achieve installation. When it is disassembled for inspection, the top cover 5 can be removed by separating the reinforcement component 10 and pulling the two pulling plates 9. The internal busbar core 1 can be observed, thereby improving the convenience of subsequent inspection.

[0034] By setting the plug-in block 7, when installing or disassembling, the plug-in block 7 can be hidden in the movable groove 6 by pulling the pulling plate 9, so that the top cover 5 can be separated from the base 3 or directly covered on the base 3 for assembly, and the top cover can be disassembled or assembled by just pulling, thereby improving the convenience of installation and subsequent disassembly.

[0035] The reinforcement assembly 10 of this embodiment includes two guide rods 101 fixedly connected to the upper side of the top cover 5, an L-shaped plate 102 slidably fitted on the guide rods 101 and matched with the pulling plate 9, and an elastic pad 103 fixedly connected to one side of the inner wall of the two L-shaped plates 102;

[0036] After the installation is completed, the L-shaped plate 102 is pressed downward on the guide rod 101 so that the elastic pad 103 is stuck on the lower side of the pulling plate 9, thereby limiting the pulling plate 9 and improving the fixity of the pulling plate 9 during use.

[0037] The fixing mechanism 11 of this embodiment includes a groove plate 111 fixedly connected to the lower sides of the two bases 3, a bidirectional screw 112 rotatably fitted on the inner wall of the groove plate 111, an adjustment plate 113 threadedly fitted on the bidirectional screw 112 and slidably fitted with the groove plate 111, a telescopic plate 114 fixedly connected to the opposite side of the two adjustment plates 113 and extending to both sides of the groove plate 111, a mounting block 115 fixedly connected to one end of the telescopic plate 114, and a worm 116 rotatably fitted on one side of the inner wall of the groove plate 111 and meshing with the bidirectional screw 112;

[0038] The bidirectional screw rod 112 is provided with a worm wheel meshing with the worm 116. When the worm 116 rotates, the bidirectional screw rod 112 will rotate accordingly. The rotation of the worm 116 can drive the bidirectional screw rod 112 to rotate. Then the bidirectional screw rod 112 can push the two adjustment plates 113 to move in different directions, and the telescopic plate 114 can push the mounting block 115 to expand to different lengths, so that it can be suitable for different fixing frames during installation, thereby improving the application range of the installation.

[0039] In this embodiment, both sides of the two bases 3 are fixedly connected with reinforcement plates 12 , and the reinforcement plates 12 are used to fix the two bases 3 .

[0040] In this embodiment, two guide grooves 13 are provided on the upper side of the base 3, and a guide block 14 matching the guide groove 13 is fixedly connected to the lower side of the inner wall of the top cover 3.
