Description

Technical Field

[0001] This invention relates to the field of busbar trunking, and in particular to a safe and energy-saving busbar trunking. Background Technology

[0002] Currently, large data centers generally use rack cabinets and cables for power transmission. Cable laying is difficult, construction period is long, and safety factor is low. Busbar trunking is now often used instead of cables, especially for high current transmission, with high safety performance and strong load-bearing capacity, fully demonstrating its superiority. When busbar trunking transmits power over long distances, it usually adopts a segmented structure to meet economic requirements and the influence of busbar trunking manufacturing process. The connection between two straight sections of busbar trunking can be achieved by connecting the two ends of the busbar trunking with a busbar trunking splitting unit, or by using a connecting mechanism to achieve a fixed connection. The connecting mechanism usually includes a shell, busbar protection components, busbar connecting components, and shell connection structure. In the existing technology, each component has a number of technical defects: (1) The busbar and the busbar trunking shell are mostly directly plugged in, resulting in poor heat dissipation performance of the busbar and low safety performance. (2) Data centers have many lines, and communication lines need to be laid with the help of the busbar trunking shell. In the existing technology, the communication lines are laid on the side wall of the shell, and a cover plate is needed to fix the communication lines, which is complicated to install and inconvenient to lay. (3) The installation of the busbar bottom plate and the busbar shell usually adopts the riveting and bolt-nut connection method, which is complicated and inconvenient to disassemble. (4) The existing data center busbar end busbar protection parts are injection molded parts with embedded copper nuts for connecting the busbar and the busbar. When a large torque is used to tighten the busbar and the protection parts, the embedded copper nuts will be pulled out of the injection molded part surface, damaging the structure and affecting safe use; at the same time, embedding copper nuts in the injection molded part makes the part production process complicated and increases the cost. (5) After the existing protection parts are assembled with the busbar shell, the protection parts and the shell cannot be completely fitted, and there is a gap between them, which affects the aesthetics and reduces the electrical creepage distance, affecting the insulation performance of the protection connection. (6) The connection method of the connector is complicated and the installation is inconvenient. (7) The shell connection structure usually uses multiple fasteners to connect the connecting plate and the busbar shell. The connection method of the two busbars is simple, the connection strength is low, and the connection is easy to directly damage the shell when vibration occurs, resulting in low safety. (8) The shell connection structure requires multiple fastening bolts to connect the connecting plate and the shell, and between the connecting plates, which is inconvenient to install and has low installation efficiency.

[0035] The principle of use of this invention is:

[0036] Installation principle of this invention: 1. First, install the ground busbar and phase busbar. Insert the ground busbar into the top plate slide rail, and use fasteners to pass through the top plate hole and the ground busbar to achieve a fixed connection between the ground busbar and the housing; then insert the phase busbar into the copper busbar slot, the phase busbar is fixed by the copper busbar clamp, and slide the protective plate into the first clamp on both sides, the second clamp slide into the protective plate groove, and the side of the protective plate is attached to the side plate protrusion to connect the busbar protective plate to the side plate;

[0037] 2. Install the busbar protection component. Insert the busbar protection component into the groove of the side plate, and use one side clip to engage it with the limiting block on the bottom side of the side plate. The other side clip engages with the top of the housing. The flapper covers the outside of the groove of the side plate, thus fixing the busbar protection component to the housing. Each phase busbar extends into the busbar protection component through the busbar outlet hole. The phase busbar is laterally limited by the side limiting block of the busbar, and axially limited by the top limiting block of the busbar. Insert the nut and washer into the nut groove and washer groove respectively.

[0038] 3. Install the upper and lower cover plates of the housing connection structure. For the wiring, first secure the communication lines by inserting them into the cable trays. Next, install the upper cover plate by inserting the upper insert between the two upper limit plates and placing it over the top surface of the housing. Use fasteners that align with the holes in the upper cover plate and upper insert to clamp the upper cover plate and upper limit plates, thus fixing the upper cover plate to the housing. Then, install the lower cover plate by extending the lower insert into the housing and placing it over the bottom surface of the housing. Use fasteners that align with the holes in the lower cover plate and lower insert to clamp the lower cover plate and lower insert to clamp the side plate clips, thus fixing the lower cover plate to the housing.

[0039] 4. Install the busbar connector. Align the two busbar sections with the straight line, and fit the busbar connector against one side of the busbar protection component on both sides. Insert the positioning rod between the two busbar sections for positioning. Connect the busbar and phase busbar by passing through the bolts and extending into the sleeve of the protection component. The nut is fixed by its groove. Directly rotating the bolts can fix the busbar, phase busbar and busbar protection component.

[0040] 5. Install the side guard plate of the shell connection structure. First, insert the lower fixing block of the side guard plate into the slot of the lower cover plate. The lower cover plate limit strip cooperates with the rotation slot of the side guard plate to realize the rotation of the side guard plate and the lower cover plate. Then, cover the upper fixing block of the side guard plate over the upper cover plate limit strip. After aligning and positioning the side guard plate with the notch of the upper cover plate and the notch of the lower cover plate through the positioning hole of the side guard plate, the side guard plate and the upper cover plate are fixedly connected by bolts. Finally, tighten all the fastening bolts of the shell connection structure to complete the fixing of the shell connection structure.

[0041] 6. Install the bottom clamp plate. Take out the bottom clamp plate, pinch and bend it with your fingers and insert it between the two side plates. Release the bottom clamp plate, and the side plate clips will engage with the bottom clamp plate and the bent section to achieve an interference fit, thus fixing the side plates and bottom clamp plate together and completing the installation of the busbar trunking housing.

[0042] The beneficial effects of this invention are:

[0043] (1) The present invention can connect the phase busbar to the busbar sheath for protection, and then connect the busbar sheath to the side plate to insulate the phase busbar from the shell, thus protecting the safety of the phase busbar and providing high safety performance. The busbar sheath adopts a double-panel structure, and two phase busbars can be fixed at the same time with the same busbar sheath. The overall integrity of the phase busbar, busbar sheath and side plate is strengthened, which improves the stability of the overall structure. The phase busbar installation process is fast and efficient. At the same time, a side plate protrusion is designed between the busbar sheath and the side plate to isolate the busbar sheath from the side plate, further improving the insulation safety performance between the phase busbar and the side plate, and forming an effective airflow channel to dissipate heat from the phase busbar, which has strong heat dissipation performance.

[0044] (2) The present invention will provide a wire groove on the top side of the housing, which can be used to fix the communication line in the wire groove, and no cover plate is needed to fix the communication line. The installation is simple and the wiring is convenient.

[0045] (3) The present invention designs the bottom fastener plate with raised stripes on its surface to improve its structural strength, enabling it to withstand greater lateral shear stress, enhancing its deformation resistance, increasing the number of times it can be bent and disassembled, and extending its service life. The bottom fastener plate features a locking strip design; when loading the bottom fastener plate, the side plate locking blocks can slide more smoothly into the housing using the inclined surface of the bent section, and the bottom fastener plate is then fixed by the interference fit between the side plate locking blocks, the bottom fastener plate, and the bent section. The present invention uses a snap-fit ​​connection between the bottom fastener plate and the side plate, strengthening the structural strength of the bottom fastener plate, making it easy to assemble and disassemble, and extending its service life.

[0046] (4) The present invention improves the design of the busbar protection component, abandons the use of embedded copper nuts, and adopts a sleeve form, in which nuts and washers can be embedded in the sleeve. The detachable embedded structure facilitates the installation and replacement of nuts and washers. When the bolts are tightened with a large torque, the bolts and nuts can be secured. The busbar protection component can withstand a large torque, has strong safety, and is easy to install. At the same time, the manufacturing process of the busbar protection component is simple and the production cost is low.

[0047] (5) After the protective component of the present invention is snapped into the busbar housing by the clip, it can cover the outside of the busbar housing by the flap set on the protective component, thereby blocking the gap between the busbar housing and the busbar protective component, improving the aesthetics of the busbar connection, and at the same time lengthening the creepage distance of the phase busbar, improving the insulation performance of the structure.

[0048] (6) The present invention designs the connection form of the busbar connector, which limits the connection busbar and the bottom plate of the connector through the connector limiting block. The busbar connector and the two sides can be directly fixed by bolts. The connection structure is simple, stable and easy to install.

[0049] (7) The present invention connects the two straight sections of the busbar trunking by using multiple connecting plates. The top and bottom of the busbar trunking are clamped together by cover plates, insert plates and fasteners. This avoids opening holes in the shell, does not affect the shell strength, and the overall connection strength with the shell is high. The connection has strong vibration resistance, the connection structure is firm, and the use is safe.

[0050] (8) In this invention, one end of the side guard plate of the connecting protective structure is connected to the lower cover plate in the form of a snap-fit. The side guard plate and the lower cover plate can rotate. The other end of the side guard plate is connected to the upper cover plate through the side guard plate fastening bolts. The side guard plate adopts a detachable and rotatable connection form, which omits the connection method of multiple fastening bolts. The installation form is flexible and convenient, which improves the installation efficiency. Attached Figure Description

[0106] Installation principle of this invention: 1. First, install the ground busbar and phase busbar. Insert the ground busbar into the top plate slide rail, and use fasteners to pass through the top plate hole and the ground busbar to achieve a fixed connection between the ground busbar and the housing; then insert the phase busbar into the copper busbar slot, the phase busbar is fixed by the copper busbar clamp, and slide the protective plate into the first clamp on both sides, the second clamp slide into the protective plate groove, and the side of the protective plate is attached to the side plate protrusion to connect the busbar protective plate to the side plate;

[0107] 2. Install the busbar protection component. Insert the busbar protection component into the groove of the side plate, and use one side clip to engage it with the limiting block on the bottom side of the side plate. The other side clip engages with the top of the housing. The flapper covers the outside of the groove of the side plate, thus fixing the busbar protection component to the housing. Each phase busbar extends into the busbar protection component through the busbar outlet hole. The phase busbar is laterally limited by the side limiting block of the busbar, and axially limited by the top limiting block of the busbar. Insert the nut and washer into the nut groove and washer groove respectively.

[0108] 3. Install the upper and lower cover plates of the housing connection structure. For the wiring, first secure the communication lines by inserting them into the cable trays. Next, install the upper cover plate by inserting the upper insert between the two upper limit plates and placing it over the top surface of the housing. Use fasteners that align with the holes in the upper cover plate and upper insert to clamp the upper cover plate and upper limit plates, thus fixing the upper cover plate to the housing. Then, install the lower cover plate by extending the lower insert into the housing and placing it over the bottom surface of the housing. Use fasteners that align with the holes in the lower cover plate and lower insert to clamp the lower cover plate and lower insert to clamp the side plate clips, thus fixing the lower cover plate to the housing.

[0109] 4. Install the busbar connector. Align the two busbar sections with the straight line, and fit the busbar connector against one side of the busbar protection component on both sides. Insert the positioning rod between the two busbar sections for positioning. Connect the busbar and phase busbar by passing through the bolts and extending into the sleeve of the protection component. The nut is fixed by its groove. Directly rotating the bolts can fix the busbar, phase busbar and busbar protection component.

[0110] 5. Install the side guard plate of the shell connection structure. First, insert the lower fixing block of the side guard plate into the slot of the lower cover plate. The lower cover plate limit strip cooperates with the rotation slot of the side guard plate to realize the rotation of the side guard plate and the lower cover plate. Then, cover the upper fixing block of the side guard plate over the upper cover plate limit strip. After aligning and positioning the side guard plate with the notch of the upper cover plate and the notch of the lower cover plate through the positioning hole of the side guard plate, the side guard plate and the upper cover plate are fixedly connected by bolts. Finally, tighten all the fastening bolts of the shell connection structure to complete the fixing of the shell connection structure.

[0111] 6. Install the bottom clamp plate. Take out the bottom clamp plate, pinch and bend it with your fingers and insert it between the two side plates. Release the bottom clamp plate, and the side plate clips will engage with the bottom clamp plate and the bent section to achieve an interference fit, thus fixing the side plates and bottom clamp plate together and completing the installation of the busbar trunking housing.

[0112] The beneficial effects of this invention are:

[0113] (1) The present invention can connect the phase busbar to the busbar sheath for protection, and then connect the busbar sheath to the side plate to insulate the phase busbar from the shell, thus protecting the safety of the phase busbar and providing high safety performance. The busbar sheath adopts a double-panel structure, and two phase busbars can be fixed at the same time with the same busbar sheath. The overall integrity of the phase busbar, busbar sheath and side plate is strengthened, which improves the stability of the overall structure. The phase busbar installation process is fast and efficient. At the same time, a side plate protrusion is designed between the busbar sheath and the side plate to isolate the busbar sheath from the side plate, further improving the insulation safety performance between the phase busbar and the side plate, and forming an effective airflow channel to dissipate heat from the phase busbar, which has strong heat dissipation performance.

[0114] (2) The present invention will provide a wire groove on the top side of the housing, which can be used to fix the communication line in the wire groove, and no cover plate is needed to fix the communication line. The installation is simple and the wiring is convenient.

[0115] (3) The present invention designs the bottom fastener plate with raised stripes on its surface to improve its structural strength, enabling it to withstand greater lateral shear stress, enhancing its deformation resistance, increasing the number of times it can be bent and disassembled, and extending its service life. The bottom fastener plate features a locking strip design; when loading the bottom fastener plate, the side plate locking blocks can slide more smoothly into the housing using the inclined surface of the bent section, and the bottom fastener plate is then fixed by the interference fit between the side plate locking blocks, the bottom fastener plate, and the bent section. The present invention uses a snap-fit ​​connection between the bottom fastener plate and the side plate, strengthening the structural strength of the bottom fastener plate, making it easy to assemble and disassemble, and extending its service life.

[0116] (4) The present invention improves the design of the busbar protection component, abandons the use of embedded copper nuts, and adopts a sleeve form, in which nuts and washers can be embedded in the sleeve. The detachable embedded structure facilitates the installation and replacement of nuts and washers. When the bolts are tightened with a large torque, the bolts and nuts can be secured. The busbar protection component can withstand a large torque, has strong safety, and is easy to install. At the same time, the manufacturing process of the busbar protection component is simple and the production cost is low.

[0117] (5) After the protective component of the present invention is snapped into the busbar housing by the clip, it can cover the outside of the busbar housing by the flap set on the protective component, thereby blocking the gap between the busbar housing and the busbar protective component, improving the aesthetics of the busbar connection, and at the same time lengthening the creepage distance of the phase busbar, improving the insulation performance of the structure.

[0118] (6) The present invention designs the connection form of the busbar connector, which limits the connection busbar and the bottom plate of the connector through the connector limiting block. The busbar connector and the two sides can be directly fixed by bolts. The connection structure is simple, stable and easy to install.

[0119] (7) The present invention connects the two straight sections of the busbar trunking by using multiple connecting plates. The top and bottom of the busbar trunking are clamped together by cover plates, insert plates and fasteners. This avoids opening holes in the shell, does not affect the shell strength, and the overall connection strength with the shell is high. The connection has strong vibration resistance, the connection structure is firm, and the use is safe.

[0120] (8) In this invention, one end of the side guard plate of the connecting protective structure is connected to the lower cover plate in the form of a snap-fit. The side guard plate and the lower cover plate can rotate. The other end of the side guard plate is connected to the upper cover plate through the side guard plate fastening bolts. The side guard plate adopts a detachable and rotatable connection form, which omits the connection method of multiple fastening bolts. The installation form is flexible and convenient, which improves the installation efficiency.
