Description

Technical Field

[0001] This invention relates to the field of busbar trunking, and in particular to a safe busbar trunking digital system. 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 trough shell. The connection method of the two ends of the busbar trough is simple, the connection strength is low, and the connection point is easy to directly damage the shell when vibration occurs, resulting in low safety. (8) The shell connection structure requires multiple fastening bolts between the connecting plate and the shell, and between the connecting plates, which is inconvenient to install and has low installation efficiency. (9) The traditional busbar through-wire hoisting scheme punches installation holes on the top of the busbar shell and connects them with through-wires. The top of the through-wire is connected to a section of channel steel, which has holes punched on it for connecting with the through-wires and holes for connecting with expansion bolts on the top of the wall. When drilling expansion bolts on the top of the wall, the positioning needs to be based on the spacing of the installation holes on the busbar shell. In this scheme, the channel steel is heavy, making it inconvenient to install and remove. At the same time, the expansion bolt holes on the top of the wall need to be positioned according to the installation holes on the busbar. To ensure correct installation, the designer needs to provide an installation drawing, which is inconvenient to install.

[0003] The busbar plug-in box is a mechanical linkage control device with safety protection function constructed between the box body, box cover, busbar contacts and shunt circuit breaker, and is used to install at the bottom of the busbar trough. (1) The back plate processing of the existing plug-in box requires countersunk holes to be made on the back plate profile so that it can be fixed with countersunk screws to the side sealing plate, which makes the processing process of the back plate profile more complicated. (2) The RJ45 network cable hole corresponding to the monitoring module is made by die stamping, and its position on the back plate is fixed. If the installation position of the monitoring module is changed, the stamping die needs to be remade. The entire back plate processing steps and the number of stamping dies required are relatively large, which makes the production process complicated and requires more time. (3) The fixing plate used to fix the micro-break support frame and the monitoring module support frame in the existing plug-in box uses two outward-facing L-shaped plates, and then uses 4 screws to fasten the support frame. At the same time, it is also necessary to drill holes and tap on the fixing plate, which is complicated and the fixing effect is not stable. (4) The existing micro-fracture support frame uses an integrated U-shaped plate, the size of which requires the cutting edge of the bending machine. If the distance is too short, a small cutting edge is required. (5) In the existing monitoring module, the main board and the CT integrated board are installed on different brackets. As a result, two brackets are needed to fix the monitoring module, which will consume manpower and time during assembly. (6) The plug-in terminal block with internal springs in the existing plug-in parts is made of powder metallurgy. Under the same plug-in plastic parts, due to the influence of volume and process, there are requirements for the wire diameter. The maximum wire diameter that can be buried is 6 square millimeters. After the wire is buried, a yellow wax sleeve is required as an outer insulating layer. (7) Moreover, due to the limited volume of the plug-in plastic parts, the gap between the electrical terminals on both sides of the plug-in plastic parts is small, which can easily cause short circuit accidents and pose a safety hazard. (8) The locking mechanism on the side plate cannot fix the rotating handle when locked, which can easily cause misoperation and lead to the plug-in box falling. Summary of the Invention

[0056] The beneficial effects of this invention are:

[0057] (1) The busbar trunking can connect the phase busbars to the busbar sheath for protection, and then connect the busbar sheath to the side plate, insulating the phase busbars from the housing, thus protecting the safety of the phase busbars 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 busbars, busbar sheaths, and side plates is strengthened, improving 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 busbars and the side plate, and forming an effective airflow channel for heat dissipation of the phase busbars, providing strong heat dissipation. The busbar trunking will have a cable trough on the top side of the housing, which can be used to fix communication lines in the cable trough without the need for a cover plate to fix the communication lines, making installation simple and cable routing convenient. The busbar trunking features a specially designed bottom mounting plate with raised stripes on its surface. This enhances the structural strength of the bottom mounting plate, allowing it to withstand greater lateral shear stress, improving its resistance to deformation, increasing the number of times it can be bent and disassembled, and extending its service life. The bottom mounting plate incorporates a locking strip design; during installation, the side plate locking blocks slide smoothly into the housing using the inclined surface of the bending section, and the bottom mounting plate is then secured by an interference fit between the side plate locking blocks, the bottom mounting plate, and the bending section. This invention utilizes a snap-fit ​​connection between the bottom mounting plate and the side plates, strengthening the structural strength of the bottom mounting plate, facilitating easy assembly and disassembly, and extending its service life. The busbar trunking system will improve the design of its busbar protection components, abandoning the use of embedded copper nuts and adopting a sleeve design. Nuts and washers can be embedded within the sleeve, featuring a detachable embedded structure for easy installation and replacement of nuts and washers. When tightening bolts with high torque, the bolts and nuts can be securely fastened, allowing the busbar protection components to withstand greater torque, ensuring high safety and convenient installation. Furthermore, the manufacturing process of the busbar protection components is simple, resulting in lower production costs. After the busbar protection components are snapped into the busbar trunking housing via clips, a flap on the protection component can cover the outside of the busbar trunking housing, concealing the gap between the housing and the protection components, improving the aesthetics of the busbar connection, and extending the creepage distance between phases, thus improving the insulation performance of the structure. The busbar connector design uses a connection method where the connecting busbar and the connector base plate are limited by connector limiting blocks. The busbar connector can be directly fixed to the phases on both sides with bolts, resulting in a simple, stable, and convenient installation structure. The busbar trunking 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, inserts and fasteners, avoiding the need to make holes in the shell, not affecting the shell strength, and the overall connection strength with the shell is high. The connection has strong vibration resistance, the connection structure is solid and the use is safe.One end of the side guard plate of the busbar trunking connection protection structure is snapped into the lower cover plate, and 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 eliminates the need for multiple fastening bolts, making the installation form flexible, convenient and improving the installation efficiency.

[0058] (2) The plug-in box has screw holes at the four corners of the inner wall of the rear panel, and the left and right side panels are fixed to the two ends of the rear panel with self-tapping screws. There is no need to process additional punching holes to install the side panels, making the fixing method more convenient and effectively reducing the manufacturing process. Compared with the existing ones that have network cable holes on the rear panel, the plug-in box sets the network cable holes on the front panel. When the monitoring module needs to be adjusted, only the front panel needs to be reprocessed, saving the complicated process of reprocessing the rear panel, while saving mold opening costs and reducing the manufacturing process. Compared with the two outward-facing L-shaped fixing plates on the existing rear panel, the plug-in box changes the fixing plates to two inward-facing L-shaped fixing plates, and has a panel in the two fixing plates. The panel is equipped with a rivet nut, and the micro-fracture support frame and the monitoring module support frame are fixed to the panel with bolts. The movement of the micro-fracture support frame and the monitoring module support frame is prevented by friction. There is no need to drill and tap on the fixing base. Each support frame only needs two screws to be fixed, and the fixing method is also more reliable. The rear support plate in the micro-fracture support frame is fixedly connected to the front support plate using bolts and nuts with interlocking holes, allowing for adjustable distance between the front and rear support plates. This facilitates the installation of components of different heights and their integration with the front plate. Compared to existing monitoring modules where the main board and CT integrated board are mounted on separate brackets, this invention mounts both the main board and CT integrated board simultaneously on the monitoring module support frame, facilitating streamlined assembly and reducing assembly time. This invention uses a partition to separate the left and right plug-in terminals, forming two independent cavities. This prevents short circuits caused by insufficient clearance between the left and right plug-in terminals. Furthermore, the partition has a through cavity, allowing the wiring of the PE plug-in terminal to pass through the cavity to the outlet, isolating it from the left and right plug-in terminals, further increasing the safety of the connectors. Compared to existing plug-in terminals using spring connections, this invention uses umbrella-shaped plug-in terminals made of beryllium bronze, which are highly elastic, easily recover their original shape after compression, making wiring more convenient, practical, and effectively improving wiring efficiency. When the locking mechanism on the left side panel is in the locked state, the adjustment knob can be pressed to make the knob plate embed into the recess of the fixing seat, thereby limiting and fixing the adjustment knob, effectively preventing the locking mechanism from loosening due to misoperation, and further improving the safety of fixing the plug box and busbar trunking.

[0059] (3) The lifting plates of the hoisting components are made of stamped steel plates. Compared with the original channel steel with punched holes, the steel plate components reduce metal consumption, are lightweight, and are easy to install and handle. Furthermore, since the data center busbar itself is not heavy, the steel plate components are sufficient to meet its strength requirements. When hoisting the busbar on site, only holes for fixing expansion bolts need to be drilled in the top of the wall according to the location where the busbar needs to be installed. The busbar does not need to use mounting holes and through-thread connections. Designers only need to draw the hoisting component diagram and count the number of hoisting components, making the installation convenient and simple. Attached Figure Description
