Abstract

The utility model discloses a passage bus structure of the passage of a potroom, which comprises upright post buses (1) on the electricity input side of an electrolytic cell at one end of the passage, and upright post buses (4) on the electricity output side of an electrolytic cell at the other end of the passage, big buses (2) connected with the electrolytic cell upright post buses are arranged between the two electrolytic cells, and the passage bus structure is characterized in that a soft bus (3) is arranged between each two big buses on both ends. The passage bus structure has the advantages of reasonable stressing, simple structure, material saving, safety, reliability, etc. and can prevent the passage buses from expansion which causes the displacement or damage of the electrolytic cell upright post buses connected with the passage buses, thus improving the safety of electrolytic production.

Description

The corridor bus structure

Technical field

The utility model relates to a kind of corridor bus structure of potroom vestibule.

Technical background

At present, along with the continuous increase of electrolysis series groove number, for the needs in workshop transportation and the production management, electrolytic series is divided into a plurality of zones usually.Between potroom district and district, the electrolytic series electric current will be realized by corridor bus.

Be directly to connect for the corridor bus between the electrolyzer at potroom vestibule two ends by big bus in the past.The shortcoming of this structure is: in the Aluminium Electrolysis process, around the electrolyzer, all have powerful direct magnetic field in the groove, big bus between the electrolyzer is also by powerful galvanic current, the magnetic field of its generation and the Interaction Law of Electric Current on the bus produce electromagnetic force, therefore corridor bus is subjected to various electromagnetic forces and does time spent expansion and generation skew easily, with corridor bus length is that 22m is an example, about its current density～0.45, increase along with surface temperature, length will increase～30mm, therefore can make the displacement of electrolyzer riser bus bar or the destruction that are attached thereto, thereby influence the ordinary production of electrolyzer, cause tremendous loss.

Summary of the invention

The technical problems to be solved in the utility model is: a kind of corridor bus structure is provided, the connection bus that this bus structure makes electrolyzer is done the time spent and can be shifted being subjected to magnetic field force, can improve the safety performance of electrolysis production greatly, cause the displacement of electrolyzer riser bus bar or destroy to overcome the expansion that prior art exists and to produce skew, thereby influence the ordinary production of electrolyzer, cause tremendous loss.

The utility model is to constitute like this: it comprises passageway one end electrolyzer electricity input side riser bus bar 1, the false riser bus bar 4 of passageway the other end electrolyzer electricity output side, between these two electrolyzers, the big bus 2 that is connected with the electrolyzer riser bus bar is arranged, soft bus 3 is arranged between the big bus at two ends.

The cross section of soft bus 3 is 70%～80% of a big busbar cross-section, and length is 1000～2000mm.

By adopting said structure, the utility model is compared with old-fashioned corridor bus structure, has stressed reasonable, simple in structure, material saving, advantage such as safe and reliable, and the expansion of avoiding corridor bus makes and is attached thereto displacement of electrolyzer riser bus bar or the destruction that connects, thereby has improved the safety performance of electrolysis production.

Embodiment

Embodiment of the present utility model: as shown in drawings, the utility model comprises passageway one end electrolyzer electricity input side riser bus bar 1, the false riser bus bar 4 of passageway the other end electrolyzer electricity output side, and big bus 2 and soft bus 3.Corridor bus between the electrolyzer at potroom vestibule two ends becomes the structure that connects soft bus 3 between the big bus 2 in two ends by an original big bus, and the cross section of soft bus 3 is 70%～80% of a big busbar cross-section, and soft bus length is 1000～2000mm.

Claims (2)

1. corridor bus structure, it comprises passageway one end electrolyzer electricity input side riser bus bar (1), the false riser bus bar (4) of passageway the other end electrolyzer electricity output side, the big bus (2) that is connected with the electrolyzer riser bus bar is arranged between these two electrolyzers, it is characterized in that: between the big bus (2) at two ends, soft bus (3) is arranged.

2. corridor bus structure according to claim 1 is characterized in that: the cross section of soft bus (3) is 70%～80% of a big busbar cross-section, and length is 1000～2000mm.
