Description

Technical Field

[0001] The utility model belongs to the technical field of bus ducts, and particularly relates to a stable type of enclosed bus duct with high density. Background Art

[0002] A bus duct is a closed metal device composed of copper or aluminum bus bars, and its function is to transmit electric energy. Compared with electric wires and cables, it can carry a larger current for transmission. Therefore, bus ducts are widely used in places where high-power current needs to be transmitted. The enclosed bus duct with high density is a type of bus duct, which is applicable to the power supply and distribution systems of three-phase four-wire and three-phase five-wire systems, with a frequency of 50 to 60 Hz, a rated voltage up to 690 V, and a rated working current of 250 to 5000 A. When connecting the enclosed bus duct with high density, generally, insulating bolts are used to penetrate and fix the connecting copper bars, conductive plates, and the external sealing shell. However, this method has certain drawbacks. Firstly, the conductive plate needs to be drilled to cooperate with the insulating bolts, which will reduce the conductive efficiency. Secondly, during installation, the insulating bolts need to penetrate numerous installation holes, which has a certain degree of operation difficulty, and the installation process is prone to instability, ultimately affecting the installation stability of the bus duct. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a stable type of enclosed bus duct with high density, so as to solve the problems of reduced power-on efficiency, difficult installation operation, and unstable installation caused by the existing direct penetration and fixing method of insulating bolts for bus ducts in the above-mentioned background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A stable type of enclosed bus duct with high density includes two bus duct bodies. A connecting copper bar is connected to the end of each bus duct body. A conductive plate is filled and installed between the connecting copper bars. A connecting component is sleeved outside the connecting copper bars. The connecting component includes connecting side plates, docking heads, inserting rods, inserting holes, movable covers, fixing plates, bolts, and sealing covers. The connecting side plates are fixed to the ends of the bus duct bodies and are distributed outside the outermost connecting copper bars. The docking heads are fixed to the ends of the connecting side plates. The inserting rod is fixed to the end of one of the docking heads and is inserted into the inserting hole opened on the surface of the other docking head. There are two sealing covers, which cover the left and right sides of the connecting side plates. The bottom end of the sealing cover is fixedly connected with a fixing plate. The opposite fixing plates are fixedly connected by bolts. The movable cover is rotatably connected to the top end of the sealing cover. A fixing plate is fixed to the end of the movable cover. The opposite fixing plates are fixedly connected by bolts.

[0005] Preferably, the conductive plate further includes a plate body and inserting feet. The inserting feet are fixed to the bottom end of the plate body.

[0006] Preferably, the connection component further includes a bottom pad and a slot. The bottom pad is fixed to the inner bottom of the sealing cover. The slot is formed on the surface of the bottom pad and is adapted to the pin. The pin is inserted into the slot.

[0007] Preferably, the connection component further includes a rubber pad. The rubber pad is fixed to the bottom surface of the movable cover plate and contacts the top end of the plate body.

[0008] Preferably, the busbar trunking body includes end plates. The end plates are symmetrically distributed on the upper and lower sides of the busbar trunking body. A reinforcing frame is fixedly connected between the end plates. The end plates and the reinforcing frame form a triangular structure.

[0009] Preferably, an elastic telescopic rod is arranged between one sides of the upper and lower end plates. Support pieces are fixed to the upper and lower ends of the elastic telescopic rod. The support pieces support the end plates.

[0010] Preferably, the busbar trunking body further includes a docking rod and a docking hole. The docking rod is fixed to the surface of the support piece and is inserted into the docking hole formed on the surface of the end plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] When connecting two busbar trunking bodies, the insertion rod can be first inserted into the insertion hole to complete the positioning between the two busbar trunking bodies, improving the stability of subsequent installation. Then, the two sealing covers can be installed on both sides of the connecting side plate and fixedly connected by fixing plates and bolts. Then, the plate body is inserted between adjacent connecting copper bars. Finally, the two movable cover plates are flipped and closed and fixed by fixing plates and bolts, thus completing the connection of the busbar trunking bodies. Under this design, the integrity of the plate body will not be damaged, ensuring the power-on efficiency. And the positioning of the busbar trunking bodies is completed before fixing, reducing the difficulty of subsequent installation and ensuring the stability after installation.
