Abstract
The utility model relates to a connection structure of buses, in particular to a connection structure of rectifier cabinet direct current outlet buses and direct current distribution buses of a rectifier station of an electrolytic aluminum factor. The connection structure comprises the direct current distribution buses and the rectifier cabinet direct current outlet buses, wherein the rectifier cabinet direct current outlet buses are connected with copper cylinders of copper-aluminum transition pieces; aluminum boards of the copper-aluminum transition pieces are welded with one ends of flexible aluminum connectors; and the other ends of the flexible aluminum connectors are welded with the direct current distribution buses. The connection structure has the advantages that after the adoption of the connection structure, the shortcoming of the connection of copper-aluminum buses is well overcome by the copper-aluminum transition pieces; one-time investment in the buses is saved; and convenience is provided for a wireman needing to disassemble the rectifier cabinet when the rectifier cabinet is overhauled.
Description
Technical field
The utility model relates to a kind of syndeton of bus, relates in particular to the syndeton of a kind of electrolytic aluminium factory rectifier rectifier cabinet direct current outlet bus and DC distribution bus.
Background technology
In recent years, aluminum electrolyzation technology develops rapidly, and the electrolytic series galvanic current reaches more than the 500kA.Along with the continuous increase of electrolytic series galvanic current, the specification of dc bus also constantly increases.The increase that this just causes dc bus once to invest has also increased difficulty for the installation and the maintenance of the dc bus of big specification; In case and deviation appears in the bus installation dimension, this part bus will be scrapped, and so both influence the construction and installation cycle, also bring very big financial loss.Simultaneously because copper bus-bar is generally adopted in the outlet of rectifier cabinet direct current; Corresponding traditional rectifier cabinet is drawn bus and is also adopted copper busbar; And the DC distribution bus often adopts aluminium busbar, and the place of copper aluminium connection is difficult to welding like this, and the bolt crimping unavoidably produces heating, deformation and oxidative phenomena again at the contact surface place; This has just influenced stability and safety that direct current is carried, produces corresponding electric energy loss simultaneously again.
Summary of the invention
In order solve the problems of the technologies described above the utility model the syndeton of a kind of rectifier cabinet direct current outlet bus and DC distribution bus, purpose to be provided is the investment with the saving dc bus, and dc bus is installed and convenient maintenance flexibly.
In order to solve the problems of the technologies described above the syndeton that the utility model is achieved in that rectifier cabinet direct current outlet bus and DC distribution bus; Comprise DC distribution bus and rectifier cabinet direct current outlet bus; Rectifier cabinet direct current outlet bus is connected with the copper post of copper-aluminium transition spare; The end welding that the aluminium sheet of copper-aluminium transition spare and aluminum are flexible coupling, the other end that aluminum is flexible coupling and the welding of DC distribution bus.
The copper post of described copper-aluminium transition spare is 4, and every is provided with bolt hole, and the copper post is vertical with aluminium sheet, in every side of rectifier cabinet direct current outlet bus two copper posts is set, and copper post and rectifier cabinet direct current outlet bus are through the bolt crimping.
The utility model has the advantages of: after adopting the utility model, copper-aluminium transition spare has well solved the problem that the copper aluminium busbar connects; And behind copper-aluminium transition spare, all adopt aluminium busbar, and do not adopt traditional copper busbar, so just practiced thrift bus once to invest; And the junction adopts aluminum to be flexible coupling; Can compensate expanding with heat and contract with cold of bus like this; Can install bus more flexibly again,, also can be flexible coupling to remedy deviation through the adjustment aluminum in case deviation appears in the bus installation dimension; So both make things convenient for installation, solved the influence that bus installation dimension deviation is brought again; Also have the copper post and the rectifier cabinet direct current outlet bus of copper-aluminium transition spare to adopt the bolt crimping, need dismantle rectifier cabinet during like this for maintenance convenience is provided.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further elaborated.
The syndeton of the utility model rectifier cabinet direct current outlet bus as shown in the figure and DC distribution bus; Comprise DC distribution bus 4 and rectifier cabinet direct current outlet bus 7; Rectifier cabinet direct current outlet bus 7 is connected with the copper post 9 of copper-aluminium transition spare 2; Be flexible coupling 3 the other end of be flexible coupling 3 the end welding of the aluminium sheet 10 of copper-aluminium transition spare 2 and aluminum, aluminum welds with DC distribution bus 4; The copper post 9 of copper-aluminium transition spare 2 is 4; Every is provided with bolt hole 6; Copper post 9 is vertical with aluminium sheet 10, in every side of rectifier cabinet direct current outlet bus 7 two copper posts 9 is set, and copper post 9 and rectifier cabinet direct current outlet bus 7 are through bolt 8 crimping; To make things convenient for rectifier cabinet 1 field-strip, DC distribution bus 4 is located on the support insulator 5.
The utility model is through the transition of copper-aluminium transition spare 2 fine completion copper aluminium busbars; Simultaneously aluminum is flexible coupling 3, and it is more flexible that the bus on rectifier cabinet 1 top is installed, in case and installation process median generatrix size or installation dimension deviation appears, also can remedy deviation through be flexible coupling 3 adjustment of aluminum.
Claims (2)
1. the syndeton of rectifier cabinet direct current outlet bus and DC distribution bus; Comprise DC distribution bus and rectifier cabinet direct current outlet bus; It is characterized in that rectifier cabinet direct current outlet bus is connected with the copper post of copper-aluminium transition spare; The end welding that the aluminium sheet of copper-aluminium transition spare and aluminum are flexible coupling, the other end that aluminum is flexible coupling and the welding of DC distribution bus.
