Safe energy-saving bus duct

Abstract

The invention discloses a safe energy-saving bus duct comprising a shell, a ground row, a phase row, bus protection pieces, a bus connector and a shell connection structure; the shell comprises a topplate, a side plate, a bus sheath and a bottom buckle plate; the bus protection piece comprises a protection piece base plate, a flange, a bus side limiting block, a bus top limiting block, a clampingstrip, a turn plate and a protection piece sleeve; the bus protection piece is inserted into the slot of the side plate, and clamped into the limiting block on the bottom side of the side plate via aside clamping strip; the bus connector comprises a connection bus, a connector base plate, a connector limiting block, a locating rod and a connector sleeve; the bus connector is arranged between thetwo bus protection pieces; the shell connection structure comprises an upper cover plate, an upper embedding plate, a lower cover plate, a lower embedding plate, a side protection plate and a side protection plate fastening bolt; the two shell sections are fixedly connected via the shell connection structure. The safe energy-saving bus duct provided by the invention is high in whole structural strength, simple and convenient in installation method and fast to install; the whole structure is high in security performance, the manufacturing technology of parts is simple, and the whole structureis low in production cost.

Description

technical field [0001] The invention relates to the field of bus ducts, in particular to a safe energy-saving bus duct. Background technique [0002] At present, large-scale data centers generally use the power transmission method of column cabinets and cables, which is difficult to lay cables, has a long construction period, and has a low safety factor; bus ducts are often used instead of cables, especially for high-current transmission. High safety performance, Strong carrying capacity fully reflects its superiority. When the busway is used for long-distance transmission of electricity, it meets the economical requirements, the manufacturing process of the busway and other factors, and the busway usually adopts a segmented structure. The busway connection of two straight sections can be connected to the busway at both ends by the busway tap unit, or the fixed connection can be realized by the connection mechanism. The connection mechanism usually includes the shell, the b...

AI Technical Summary

Problems solved by technology

The busway connection of two straight sections can be connected to the busway at both ends by the busway tap unit, or the fixed connection can be realized by the connection mechanism. The connection mechanism usually includes the shell, the busbar protection part, the busbar connector, Shell connection structure, in the prior art, there are many technical defects in each component: (1) The busbar and the busway shell are mostly connected by direct plug connection, the heat dissipation performance of the busbar is poor, and the safety performance is low

(2) There are many lines in the data center, and the communication lines need to be arranged with the help of the busway housing. In the prior art, the communication lines are laid on the side wall of the housing, and a cover plate is required to fix the communication lines. The installation is complicated and the wiring inconvenient

(3) The installation of the busway bottom gusset and the busway shell is usually connected by riveting, bolts and nuts. The installation and connection form is complicated and inconvenient to disassemble

(4) The busbar protection parts at the end of the busway in the existing data center are injection molded parts, with copper nuts embedded in them, which are used to connect the connecting row and the busbar. When using a large torque to fasten the busbar and the protective part, The embedded copper nut will be pulled out of the surface of the injection molded part, damaging the structure and affecting safe use; at the same time, the copper nut embedded in the injection molded part will cause cumbersome production process and increase the cost of the part

(5) After the existing protective part is assembled with the busbar shell, the protective part and the shell cannot be completely fitted, and there is a gap between the two, which affects the appearance and reduces the electrical creepage distance, affecting the insulation performance of the protective connection

(6) The connection method of the connector is complicated and the installation is inconvenient

(7) The connection structure of the shell usually adopts the connection between the connecting plate and the busway shell through multiple fasteners. The connection method of the busway at both ends is simple, and the connection strength is low. When vibration occurs, the connection is easy to be directly damaged. Housing, low safety; (8) The connection structure of the housing requires multiple fastening bolts to connect between the connecting plate and the shell, and between the connecting plate and the connecting plate, which is inconvenient to install and low in installation efficiency
