Description

Technical Field

[0001] The invention belongs to the field of power transmission, and in particular relates to a bus duct with side diversion. Background Art

[0002] Bus duct, as an efficient power transmission equipment, is widely used in buildings, industries and power systems to transmit and distribute large currents. It consists of a metal trough, insulating materials and conductive busbars, and has the characteristics of compact structure, high transmission efficiency and easy maintenance. The bus duct is designed to provide a safe, reliable and economical way to transmit power while reducing energy losses and improving system stability.

[0003] When existing bus ducts are used outdoors or in humid environments, they often face the problem of surface water accumulation. This water may come from rainwater, condensation or other liquids. If the accumulated water cannot be discharged in time, it may cause corrosion on the surface of the bus duct, thus affecting its insulation performance and service life.

[0004] When traditional dense bus ducts are installed vertically, if water falls from above, the water can quickly flow away through the lifting holes or other designed drainage holes, effectively avoiding the accumulation of moisture on the surface of the bus duct, thereby reducing the risk of short circuits caused by moisture. However, when the bus duct is installed horizontally, the situation is quite different. If water falls from above, moisture is likely to accumulate on the side panels of the bus duct. Over time, this accumulated moisture may gradually penetrate into the bus duct, causing short circuits, corrosion and other problems, seriously threatening the safety and reliability of the system. Even when placed vertically, there are problems with the drainage hole design of some bus ducts. The drainage path usually passes through the gaps between the shells, which may expand due to wear, aging or corrosion after long-term use. This makes it possible for liquid to enter the bus duct through these gaps, increasing electrical safety risks. Summary of the invention

[0005] The present invention aims to provide a bus duct with side diversion to solve the technical problems of waterproofing and drainage of the bus duct during use.

[0006] To achieve the above purpose, the specific technical solution of a side-guiding bus duct of the present invention is as follows:

[0007] A side-guiding bus duct comprises a shell structure, a busbar structure arranged in the shell structure, and connecting side ears arranged on both sides of the shell structure;

[0008] The housing structure includes two side plates and two cover plates, the side plates and the cover plates are alternately connected to form a busbar structure placement space with openings at both ends, the wiring terminals of the busbar structure extend from the openings at both ends, and the connecting side ears extend to both sides from the openings at both ends of the placement space along the extension direction of the wiring terminals;

[0009] The cover plate surface is provided with vertical drainage holes for draining liquid from the cover plate surface when the cover plate is placed upward, and the connecting side ears are provided with horizontal drainage holes for draining liquid from the side plate surface when the side plate is placed upward.

[0010] As a further improvement of the present invention, the connecting side ear includes a vertical end connected to the housing structure, an extended end arranged from the vertical end along the extending direction of the wiring terminal, and a drainage channel connected to the vertical end and below the extended end;

[0011] The horizontal drainage hole is connected to the drainage channel from the vertical end toward one side of the shell structure, and the drainage channel discharges liquid from both sides of the extending direction of the wiring terminal.

[0012] As a further improvement of the present invention, the side plate includes a clamping portion for clamping the busbar structure, and connecting portions arranged on both sides of the clamping portion and bent outward relative to the busbar structure placement space; the cover plate abuts against the connecting portion.

[0013] As a further improvement of the present invention, the cover plate is relatively exposed on the abutting surface between the connecting portion and the cover plate, and the vertical drainage hole penetrates the cover plate from the exposed portion.

[0014] As a further improvement of the present invention, the vertical end is vertically abutted against both ends of the clamping portion along the extending direction of the terminal, and the horizontal drainage hole is arranged on the vertical end surface along the surface of the clamping portion relative to the outside of the busbar structure placement space, and the upper end of the horizontal drainage hole is lower than the height of the connecting portion.

[0015] As a further improvement of the present invention, the extended end is arranged parallel to the wiring terminal along the extending direction of the wiring terminal, and the vertical end is vertically connected to the extended end.

[0016] As a further improvement of the present invention, the drainage channel is a hollow tubular structure with openings at both ends, the middle part is connected to the horizontal drainage hole, and the openings at both ends of the drainage channel protrude relative to the vertical end, and are used to discharge the liquid through the connecting cover plates on both sides of the bus duct connection.

[0017] As a further improvement of the present invention, the drainage pipe is arranged between the wiring terminal and the extending end, close to the vertical end and perpendicular to the extending direction of the wiring terminal.

[0018] As a further improvement of the present invention, a heat dissipation structure is provided on the outer surface of the side plate relative to the space where the busbar structure is placed, and the heat dissipation structure is provided with a guide groove connected to the horizontal drainage hole.

[0019] Beneficial effects:

[0020] The present invention effectively solves the problem of liquid accumulation when the bus duct is installed horizontally by providing horizontal drainage holes on the connecting side ears and combining them with internal drainage channels. Even if the side panels of the bus duct are placed upward, the liquid can be quickly discharged through the horizontal drainage holes, avoiding the accumulation and infiltration of liquid on the side panels, and significantly improving the safety of the system. Vertical drainage holes are provided on the surface of the cover plate for drainage during vertical installation. The horizontal drainage holes on the connecting side ears are specially designed for horizontal installation, achieving effective drainage in both vertical and horizontal installation situations, thereby improving the applicability and flexibility of the product. Through the side diversion design, the liquid is guided to a special drainage channel, reducing the risk of liquid directly contacting the busbar structure, thereby reducing the safety hazards of short circuits and electrical fires.

[0021] Through effective drainage design, the present invention significantly reduces short circuits, corrosion and other faults caused by liquid infiltration, and improves the stability and reliability of the busbar system. This is particularly important for power transmission and distribution systems, ensuring the continuity and safety of power supply.

[0022] The design of the connecting side ear includes a vertical end, an extended end and a drainage channel, which is compact and reasonable in structure. The connection design between the horizontal drainage hole and the drainage channel ensures the smooth discharge of the liquid. This optimized structural design not only improves the drainage efficiency, but also simplifies the installation and maintenance process.

[0023] The heat dissipation structure is set on the outside of the side plate, and the guide groove connected with the horizontal drain hole further enhances the heat dissipation effect. This not only helps to reduce the temperature inside the bus duct, prolong the service life of the equipment, but also improves the overall performance of the system.

[0024] In summary, the side guide bus duct of the present invention has significant beneficial effects in improving drainage efficiency, enhancing sealing, improving safety and stability, etc. It is suitable for various power transmission scenarios and provides a strong guarantee for the safe and stable operation of the power system.

DETAILED DESCRIPTION

[0030] In order to better understand the purpose, structure and function of the present invention, a bus duct with side guide of the present invention is further described in detail below with reference to the accompanying drawings.

[0031] Implementation example:

[0032] like Figure 1 and 2 As shown, in a bus duct with side diversion, the busbar structure 200 is laid flat in the shell structure 100 as a conductor, and the wiring terminals 210 at both ends of the busbar structure 200 are exposed from the openings at both ends of the shell structure 100. The shell structure 100 includes two side panels 110 and two cover panels 120. The side panels 110 clamp the busbar structure 200 from the upper and lower sides, and the cover panels 120 are connected to the side panels 110 from the left and right sides, forming a space for placing the busbar structure 100 inside the bus duct. The connecting side ears 300 are connected to the opening sides at both ends of the shell structure 100 along the direction in which the wiring terminals 210 are exposed. The connecting side ears 300 are provided with horizontal drainage holes 310 for draining the accumulated water on the surface of the side panels 110, and the cover panels 120 are provided with vertical drainage holes 121 for draining the accumulated water on the surface of the cover panels 120.

[0033] The side plate 110 is a П-shaped bent protrusion, the protrusion end is a clamping part 111, and the two sides of the clamping part 111 are bent connecting parts 112. The connecting part 112 is connected to the cover plate 120 by bolts. The clamping part 111 clamps the busbar inside the bus duct. The horizontal drainage hole 310 is arranged along the outer surface of the clamping part 111 to ensure that the accumulated water on the surface of the clamping part 111 smoothly enters the horizontal drainage hole 310. At the same time, the horizontal drainage hole is lower than the height of the connecting part 112 to prevent the accumulated water from entering the connection gap between the connecting part 112 and the cover plate 120. The connecting surface of the cover plate 120 and the connecting part 112, the height of the connecting part 112 is lower than the height of the cover plate 120, and the vertical drainage hole 121 arranged through the cover plate 120 passes through the gap part of the cover plate 120 that is higher than the connecting part 112. When the bus duct is placed vertically, the cover plate 120 is placed upwards, and the accumulated water is discharged from the vertical drainage holes 121; when the bus duct is placed horizontally, the side plates 110 are placed upwards, and the accumulated water is discharged from the horizontal drainage holes 310. The outer surfaces of the side plates 110 and the cover plates 120 are provided with heat dissipation teeth as heat dissipation structures, and guide grooves are provided to connect the drainage holes, so that heat can be quickly taken away during the rapid drainage process.

[0034] like Figure 3 As shown, the vertical end 320 of the connecting side ear 300 is connected to the outside of the openings at both ends of the bus duct, and the extended end 330 extends outward from the lower part of the vertical end 320. The drainage pipe 340 is a hollow tube with openings at both ends arranged at the lower part of the vertical end 320. The horizontal drainage hole 310 passes through the surface of the vertical end 320 and enters the middle of the drainage pipe 340. The openings at both ends of the drainage pipe 340 protrude to both sides relative to the vertical end 320.

[0035] like Figure 4 As shown, two bus ducts are connected by a connecting structure, and the connecting side ears 300 are connected to the busbar terminal 210 and the connector 400. The two sides are covered with sealing gaskets 500 and connecting cover plates 600 in sequence. The drainage pipe 340 is located between the terminal 210 and the protruding end 330 and is arranged close to the vertical end 320. Drainage holes 310 are arranged on the sealing gasket 500 and the connecting cover plate 600 corresponding to the openings at both ends of the drainage pipe 340. The two ends of the drainage pipe 310 pass through the drainage holes 610 to directly guide the accumulated water out of the bus duct from the side.

[0036] The bus duct of the present invention provides two drainage hole designs, vertical and horizontal. Regardless of whether the bus duct is placed vertically or horizontally, the liquid can be effectively discharged, avoiding the problem of liquid accumulation and penetration, and improving the safety and reliability of the bus duct. Through the design of connecting the side ears and the connecting cover plate, the connection has better sealing, preventing the intrusion of liquid and dust, and improving the protection level of the bus duct. The design of the clamping part and the connecting part of the side plate, as well as the abutment between the cover plate and the connecting part, form a stable busbar structure placement space, ensuring the stability and durability of the bus duct in various environments. The heat dissipation structure and the guide groove design on the outer surface of the side plate and the cover plate are conducive to the dissipation of heat, improving the heat dissipation efficiency of the bus duct, thereby ensuring the stability of power transmission and the long-term operation of the bus duct. The bus duct design of this embodiment can adapt to different installation environments and methods. Whether it is installed vertically or horizontally, it can maintain good drainage performance and sealing, enhancing the applicability of the bus duct.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
