Description

Disconnecting device of passageway bus and passageway bus comprising same

Technical Field

The utility model belongs to the technical field of aluminium electroloysis, concretely relates to disconnecting device of passageway generating line reaches passageway generating line including it.

Background

An electrolysis workshop in the aluminum electrolysis industry is generally divided into a plurality of areas, each area is provided with a corresponding number of electrolysis baths, and the electrolysis baths are connected in series. In order to form a loop between each electrolytic cell and the power chamber, the current trend is as follows: the power room → the first, second and third zones of the first plant → the third, second and first zones of the second plant → the power room, and the two plants are constructed side by side in order to form a loop between each cell and the power room.

For newly-built and production-recovered electrolytic cells, in order to be capable of being produced in advance without waiting for all the electrolytic cells in two workshops to have production conditions and then producing the electrolytic cells together, a channel bus is arranged between each area of each workshop, when the electrolytic cells in the first area of the two workshops have the production conditions, the channel bus between the first area and the second area is communicated, and a power room, the first area of the first workshop and the first area of the second workshop form a loop; when the second area of the two workshops has production conditions, the channel bus between the second area and the third area is communicated, and the channel bus between the first area and the second area is disconnected, so that the power room, the first workshop area, the second workshop area and the first workshop area form a loop.

Of course, not only are there disconnections and connections of the channel bus bars in the cells newly built and newly produced, but also in the event of an accident of the cells.

Fig. 1 shows a connection state of a corridor bus bar in the prior art, wherein short-

circuit blocks

3 and 4 on the corridor bus bar 1 are fixed on the corridor bus bar 1 through bolts 6, and when the short-

circuit blocks

3 and 4 need to be removed, the bolts 6 need to be removed, but there are two problems in this way:

(1) when the short-circuit block of the passageway bus needs to be removed, the running current of the electrolytic cell must be disconnected firstly, and the disconnection time of the running current cannot exceed half an hour (a series of problems can occur when the running cell is not electrified for more than half an hour), so that the short-circuit block is removed only for half an hour; however, one short circuit block generally has 4-5 groups, one group has 32 sets of bolts, one short circuit block has 128-160 sets of bolts which need to be removed, the length of each set of bolts is between 800-1000 mm, and the self weight of each group of short circuit blocks is about 1.3 t; therefore, the time is very urgent when the aisle bus is to be dismantled, the workers are often in a mess, and once a group of other buses are dismantled, the other buses are not required to be dismantled, so that the disconnection is avoided, and the situation of difficulty in moving forward and backward is realized;

(2) the dead weight of each group of short circuit blocks is about 1.3t generally, and the short circuit blocks are not easy to transport after being disassembled, because the passing bus is positioned under the electrolytic workshop channel, the bus cannot be communicated, and the periphery of the passing bus is blocked by buildings, so that great manpower and material resources are consumed; if the electrolytic cell is required to be isolated outside the corridor bus in case of emergency, the half hour of power failure time cannot meet the requirement of reinstallation of the short-circuit block.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a disconnection device of passageway generating line, include: the insulating plate is inserted between the first short circuit block and the second short circuit block so as to separate the first short circuit block from the second short circuit block.

Preferably, the insulation values of the first insulation sleeve, the second insulation sleeve and the insulation plate are all greater than 1000M Ω.

Preferably, the cross-sectional shape of the insulating plate is L-shaped.

The utility model also provides a passageway generating line, include as in aforesaid anyone the disconnecting means.

The application provides a disconnection device of passageway generating line and including its passageway generating line has following advantage:

(1) only half of the bolts on the aisle bus need to be removed, which is equivalent to half of the removal time;

(2) the short-circuit block is still in place, if the passageway bus bar and the short-circuit block need to be reconnected, only the insulator mounting bolt needs to be taken out, the secondary transportation, mounting and dismounting of the short-circuit block are avoided in the process, compared with the existing method, half of the time and manpower are saved, the time is sufficient, and the work is orderly.
