Abstract

The utility model discloses an aluminum electrolysis tip groove electromagnetic interference resisting bus structure. Tt least one bus in the loop bus is bent by the tip bends a section of small fold line opposite to the direction of other buses at the position about 0.5 to 3 meters from the edge of the tip groove and then bends with other buses. The shape of the small fold line can be a beeline shape parallel with the edge of the tip groove or a fold line shape bending inwards at the tip groove edge. The utility model has the advantages of reducing the bending distance between the loop bus and the tip groove, and reducing the magnetic field interference of the loop bus to the tip groove.

Description

The electrolysis of aluminum end tank is prevented the electromagnetic interference bus structure

The utility model relates to the anti-electromagnetic interference bus structure of a kind of electrolysis of aluminum end tank.

At present, in the electrolytic aluminum engineering, generally all be connected with loop, the termination bus of bending on its electrolysis of aluminum end tank, all bending to same direction and loop, the termination bus of these bendings is general near identical position, in order to reduce the electromagnetic interference of loop, termination bus to end tank, the bending place of loop, general requirement termination bus is as far as possible away from end tank, this apart from general requirement greater than about 20 meters, this has not only increased bus length, but also increased the bulk of production plant, and increased electric energy loss, therefore loop, the termination bus structure of existing electrolysis of aluminum end tank still is not ideal enough.

The purpose of this utility model is: provide a kind of and can reduce the bending distance of loop, termination bus and reduce loop, termination bus simultaneously to the anti-electromagnetic interference bus structure of the electrolysis of aluminum end tank of end tank electromagnetic interference, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: it comprises the electrolysis of aluminum end tank (2) that has termination bending loop bus (1), in termination bending loop bus (1), have the structure that has a bus a at least at the edge λ of distance end tank (2) be 0.5～3 meter closely locate after the reverse direction with other bus bending is bent with one section little broken line L, together bend in company with other bus again; Bus a can be the rectilinear form parallel with the end tank edge or is the broken line shape to an end tank edge invagination part in the shape that closely bends one section little broken line L from end tank (2).

Owing to adopted technique scheme, the utility model compared with prior art the utlity model has the bending distance that can reduce loop, termination bus and reduces the advantage of loop, termination bus to the end tank electromagnetic interference simultaneously.Principle of work of the present utility model be utilize electromagnetic intensity be directly proportional with electric current, with the relation principle that is inversely proportional to of distance, it is with near from end tank (2) distance and have magnetic field that the little broken line L of little electric current produced and offset big electric current, loop bus (1) magneticinterference that end tank (2) is produced at a distance.Therefore the utility model not only has the bending distance that can reduce between loop bus (1) and the end tank (2), reduce the advantage of loop bus to the magneticinterference of end tank, and the utility model also has that configuration is simple, construction easily, less investment, outstanding effect advantage.

Structural representation when accompanying drawing 1 is parallel lines for little broken line L of the present utility model;

Accompanying drawing 2 is the broken line shape structural representation of little broken line L of the present utility model when an end tank edge invagination part.

Embodiment 1 of the present utility model: the structure of electrolysis of aluminum end tank (2) that has termination bending loop bus (1) is with of the prior art the same, during making, according to termination bending loop bus (1) to end tank (2) produce magneticstrength, getting in its termination bending loop bus (1) one or two bus a is 1.5 meters closely locating together to bend in company with other bus after the reverse direction with other bus bending bends one section little broken line L parallel with the end tank edge again and get final product at the edge λ of distance end tank (2).

Embodiment 2 of the present utility model: the structure of electrolysis of aluminum end tank (2) that has termination bending loop bus (1) is with of the prior art the same, during making, getting in the termination bending loop bus (1) one or two bus a is 2.5 meters closely locating to together bending in company with other bus again with one section of the reverse direction bending of other bus bending and behind the little broken line L of the broken line shape of an end tank edge invagination part at the edge λ of distance end tank (2).

Claims

1, the anti-electromagnetic interference bus structure of a kind of electrolysis of aluminum end tank, it comprises the electrolysis of aluminum end tank (2) that has termination bending loop bus (1), it is characterized in that: in termination bending loop bus (1), have the structure that has a bus a at least at the edge λ of distance end tank (2) be 0.5～3 meter closely locate after the reverse direction with other bus bending is bent with one section little broken line L, together bend in company with other bus again.

2, the anti-electromagnetic interference bus structure of electrolysis of aluminum end tank according to claim 1 is characterized in that: bus a can be the rectilinear form parallel with the end tank edge or is the broken line shape to an end tank edge invagination part in the shape that closely bends one section little broken line L from end tank (2).
