Abstract

The utility model discloses a vertical column bus connection structure, a soft bus-bar joint of which is connected with a bus-bar pillar via a bolt, and aluminium plates are welded on the combination seams of the joint and the bus-bar pillar. The utility model adopts a connecting structure combined by compression and weld, the connecting structure can mainly lead most of current to pass through the aluminium plates so as to increase the electric conductive performance of the combination point, therefore, the utility model can reduce the voltage drop at the combination point. According to tests, the voltage drop at the combination point can be reduced to about 6 mv by the utility model. Compared with the prior art, the utility model not only has the advantages of simple structure, reliable connection contact, good electrical conductivity, long service life and good electricity saving effect, but also has the advantages of easy enforcement and easy and simple operation.

Description

The riser bus bar syndeton

Technical field:

The utility model relates to the riser bus bar syndeton of using on a kind of aluminium cell, belongs to aluminum electrolytic cell riser bus bar interconnection technique field.

Background technology:

At present, prebaked cell for aluminum-reduction upper pillar stand bus of the prior art top is the crimping mode near the common employing of the soft bus of column place connection, though it is easy that this kind mode of connection has connection, the characteristics of easy accessibility when stopping groove overhaul, but simultaneously because the aluminium busbar surface easily generates one deck pellumina after using for some time, and riser bus bar can be out of shape by thermogenesis in process of production, the conductivity of this bus-bar compression joint surface will descend when refilling new groove like this after electrolyzer stops groove overhaul, volts lost increases, thereby causes power consumption to increase.

Summary of the invention:

The purpose of this utility model is: provide a kind of simple in structure and conductivity riser bus bar syndeton preferably, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: it comprises the bus column (1) of aluminium cell and has the soft bus (2) of joint (3), the joint (3) of soft bus (2) is connected on the bus column (1) by bolt (4), and is welded with aluminium sheet (5) on joint (3) and bus column (1) bonded bonding crack; At the dual-side of joint (3) and bus column (1), every limit is welded with an aluminium sheet (5) at least on its bonded bonding crack.

Owing to adopted technique scheme, the syndeton that the utility model has adopted crimping to combine with welding, this syndeton mainly is that most of electric current is passed through from aluminium sheet (5), increase the electroconductibility of this junction, thereby reduce the volts lost of junction, according to test, adopt the utility model the volts lost of junction can be reduced about 6mv.Therefore the utility model compared with prior art, that the utility model not only has is simple in structure, connect contact reliable, conduct electricity very well, long service life, the significant advantage of power savings, but also have implement easily, advantages of simple operation.When the overhaul groove, with under aluminium sheet (5) shovel that is welded, unload threaded stud (4) more earlier, the soft bus of column can be removed; When refilling groove, load onto threaded stud (4) and the aluminium sheet of burn-oning (5) gets final product.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the A-A cross-sectional schematic of accompanying drawing 1.

Embodiment:

Embodiment of the present utility model: the bus column (1) of aluminium cell and the soft bus (2) that has a joint (3) are the bus column that uses on the aluminium cell of the prior art and have the soft bus of joint, during making, joint (3) in soft bus (2) upward and on the bus column (1) bores 2～4 through holes respectively earlier, joint (3) with soft bus (2) is connected on the bus column (1) by 2～4 threaded studs (4) then, and at the dual-side of joint (3) with bus column (1), an aluminium sheet (5) is welded on every limit at least on its bonded bonding crack, more reliable in order to use, generally on every lateral junction joint close of joint (3) and bus column (1) two sides, weld two blocks of aluminium sheets respectively and (5).

Claims

1, a kind of riser bus bar syndeton, it comprises the bus column (1) of aluminium cell and has the soft bus (2) of joint (3), it is characterized in that: the joint (3) of soft bus (2) is connected on the bus column (1) by bolt (4), and is welded with aluminium sheet (5) on joint (3) and bus column (1) bonded bonding crack.
