DETAILED DESCRIPTION

[0025] The specific implementation modes of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The present invention designs a systematic bus duct structure device, such as Figure 1 As shown, it includes an upper cover plate 1, a lower cover plate 2, a connector 3, an upper frame structure 4, a lower frame structure 5, and other phase conductors 6 except the PE line conductor.

[0027] Among them, Figure 1 , Figure 2 , Figure 3As shown, the lower surface of the upper cover plate 1 and the upper surface of the lower cover plate 2 are opposite to each other, and each other phase conductor 6 is located between the opposite surfaces of the upper cover plate 1 and the lower cover plate 2; the upper frame structure 4 is arranged on the lower surface of the upper cover plate 1, and the upper frame structure 4 is arranged along the position of each other phase conductor 6 corresponding to the lower surface of the upper cover plate 1; the lower frame structure 5 is arranged on the upper surface of the lower cover plate 2, and the lower frame structure 5 is arranged along the position of each other phase conductor 6 corresponding to the upper surface of the lower cover plate 2.

[0028] like Figure 2 As shown, the connector 3 is arranged along the area where the upper frame structure 4 is set and between the upper frame structure 4 and the lower frame structure 5. Among the two opposite sides of the connector 3, one side is connected to the side of the upper frame structure 4 facing away from the upper cover plate 1, and the other side is connected to the side of the lower frame structure 5 facing away from the lower cover plate 2. The connector 3 divides the area between the upper cover plate 1 and the lower cover plate 2 into two inner cavities corresponding to the two sides thereof, and the connector 3 constitutes a PE line conductor.

[0029] like Figure 2 As shown, each other phase conductor 6 is evenly divided into two conductor groups, and the two conductor groups are respectively placed on both sides of the connector 3. In actual application, when a phase-to-phase and phase-to-ground short circuit occurs inside the bus duct or a phase line leakage fault occurs, the distance from each phase of the structure to the PE line is very short and consistent, and the fault current can be introduced into the ground in the shortest time; of the two opposite sides on each other on the other phase conductors 6 in each conductor group, one side points to the side of the upper frame structure 4 facing away from the upper cover plate 1 in the set area, and the other side points to the side of the lower frame structure 5 facing away from the lower cover plate 2 in the set area. In actual application, for example, each other phase conductor 6 is an L1 phase conductor, an L2 phase conductor, an L3 phase conductor, and an N phase conductor, that is, evenly divided into two conductor groups, and the two conductor groups are respectively placed on both sides of the connector 3, that is, placed on both sides of the PE line conductor, and in actual application, the surfaces of the L1 phase conductor, the L2 phase conductor, the L3 phase conductor, and the N phase conductor are all covered with an insulating layer, and for the upper cover plate 1 and the lower cover plate 2, the actual design adopts an aluminum alloy material.

In application, the two-phase conductors on the outside can quickly dissipate heat through the side panels, while the two-phase conductors on the inside can directly conduct heat to the surface of the shell with the help of the PE line conductor. At the same time, the frame structure to which the upper and lower ends of the PE line conductor are respectively connected, in addition to being able to transfer the heat of the middle part of the busbar to the outside by heat conduction, also enables the ends of each phase conductor 6 to accelerate heat conduction, thereby efficiently and quickly achieving the purpose of heat dissipation of the bus duct, greatly improving the overall heat dissipation capacity.

[0032] In actual implementation, not only hard rubber 7 is used, but also two foam rubbers 9 corresponding to each inner panel 8 are further designed and added. One foam rubber 9 is arranged along the position between the corresponding inner panel 8 and the corresponding side of the upper frame structure 4, and the other foam rubber 9 is arranged along the position between the corresponding inner panel 8 and the corresponding side of the lower frame structure 5.

[0033] In practical applications, the hard rubber 7 and the foam rubber 9 of the integrated L-shaped structure design are used by the hard rubber 7 to achieve shock absorption, noise reduction, and isolation of shell burrs between each phase conductor and the "inverted H"-shaped aluminum alloy profile shell, and based on the U-shaped structure composed of the inner plate 8 and the outer extension edges 10 connected on both sides thereof, the foam rubber 9 is used to achieve sealing between the "inverted H"-shaped aluminum alloy profile shell and the U-shaped structure, to prevent scratches between the U-shaped structure and the "inverted H"-shaped aluminum alloy profile shell during assembly, thereby ensuring the protection of the bus duct shell.

[0034] In application, the design further includes inner plates 8 corresponding to the two inner cavities between the upper cover plate 1 and the lower cover plate 2. Each inner plate 8 is arranged along the outer side of the conductor group in the corresponding inner cavity.

[0038] Based on the convex structure at the two ends of the bus duct, the present invention is further designed to include an upper end connector 12, a lower end connector 13, and two joint side plates 14 corresponding to the two ends of the bus duct, wherein each end connector has the same convex shape as the convex structure on the cover plate; wherein the upper end connector 12 is placed on the upper surface of the convex structure of the upper cover plate 1 at the corresponding end of the bus duct, and the lower end connector 13 is placed on the lower surface of the convex structure of the lower cover plate 2 at the corresponding end of the bus duct.
