Description

The disconnection method of aluminium electroloysis central gangway bus

Technical field

The invention belongs to the construction technology of aluminium cell, more particularly to a kind of disconnection side of aluminium electroloysis central gangway bus Method.

Background technology

A potroom is generally divided into several areas in aluminium electroloysis industry, i.e. a workshop is divided into several sections, often There is the electrolytic cell of respective numbers in individual area, the step mode between each electrolytic cell is series connection；In order that each electrolytic cell and power Loop can be formed between room, the trend of electric current is：One, two, three area → the second in power house → the first workshop Workshop three, two, one area → power house, so to make each electrolytic cell and power house form loop, by two workshops Build side by side.

For newly-built and electrolytic cell that is resuming production, in order to produce in advance without when two workshops are all electric Solution groove produces together after possessing operation condition, and its way is to set up passage bus between each area in each workshop, when two When the electrolytic cell in the area of workshop one possesses operation condition, the passage bus between an area and 2nd area is connected, makes power house, first car The areas of Jian mono-, second workshop one area form loop；When 2nd area in two workshops possess operation condition, 2nd area of connection and 3rd area Between passage bus, simultaneously switch off the passage bus between an area and 2nd area, such power house, the first workshop one, 2nd area, Two workshops one, 2nd area form loop.

Certainly it is not only the disconnection and connection that newly-built and electrolytic cell that is resuming production has passage bus, when electrolytic cell goes out Also the disconnection and connection of passage bus can be related to during existing accident.

Above-mentioned passage bus is the corridor bus 1 that the present invention will refer to (with reference to figure 1)；Connection status be bolt 6 are directly connected to, and mode is that the bolt at both ends is all removed used by short-circuit block 3 and corridor bus 1.This mode has at 2 points Problem：

1st, when the short-circuit busbar of corridor bus need to be removed, it is necessary to first electrolytic cell running current is disconnected, and running current Turn-off time, (a series of ask occurred in the case of cold more than half an hour in run channel no more than half an hour Topic), so only the time of half an hour removes short-circuit busbar；But short-circuit busbar typically has 4 at one --- 5 groups, one group has 32 sets of bolts, short-circuit busbar shares 128 at one --- 160 sets of bolts need to remove, and often cover bolt length 800 --- 1000mm it Between, every group of short-circuit busbar deadweight is 1.3t or so, so the time is all very urgent whenever corridor bus to be removed, staff It is often in a rush, and once removed one group remaining must remove, must not interrupt.

2nd, the deadweight of every group of short-circuit busbar is typically in 1.3t or so, disassemble it is rear it is very bad have bad luck because corridor bus It is to be located at potroom passage underground, it is impossible to be open to traffic, and surrounding has building to stop, it is necessary to expend manpower thing very big again Power.If the electrolytic cell beyond corridor bus herein need to be isolated by running into emergency, the power off time of half an hour is not The installation again of short-circuit busbar can be met.

The content of the invention

The purpose of the present invention, which is that, overcomes above-mentioned the deficiencies in the prior art, and provides in a kind of aluminium electroloysis Between corridor bus disconnection method, this method using can be effectively saved by the way of insulating on the spot corridor bus remove and installation when Between, more than half labour and time are at least saved, while the probability of accident generation can be reduced, improve processing emergency Certainty.

As above conceive, the technical solution adopted in the present invention is：A kind of disconnection method of aluminium electroloysis central gangway bus, its It is characterised by：Short-circuit block is entangled using insulator respectively in one end of every group of corridor bus, then insulation is inserted between short-circuit block Plate.

The insulation values of above-mentioned insulator are more than 1000M Ω.

The present invention has the advantage that and good effect：

1st, when removing corridor bus, the bolt of corridor bus half herein need to be only removed, is torn open equivalent to half is saved Except the time.

2nd, because short-circuit busbar is also in original place, if it need to reconnect corridor bus and short-circuit busbar, need to only take out absolutely Edge body, installation bolt, avoid during this and have bad luck, install and remove short-circuit busbar again, more existing method exists Manpower, half is saved on the time.

3rd, because the middle part of short-circuit busbar has ductility for aluminium soft ribbons, therefore the present invention completely cuts off passageway with insulator One end of bus, in the case of so fixing at one end, the other end can left and right adjusting.

Embodiment

The present invention is illustrated below in conjunction with the accompanying drawings.

A kind of disconnection method of aluminium electroloysis central gangway bus, every group of corridor bus configuration insulating sleeve 1 (7), insulation sleeve (9) the three kinds of insulators in cylinder 2 (8) and insulation board.When corridor bus need to be disconnected, corridor bus one end therein is opened, is somewhat divided Short-circuit block (3) and (4) are opened, short-circuit block (4) is entangled with insulating sleeve 1 (7), then short-circuit block (3) is entangled with insulating sleeve 2 (8), most Inserted afterwards with insulation board between short-circuit block (3) and (4).During to reconnect short-circuit block (3) and (4), only these three need to be taken out Insulator, then reinstall.

Why the present invention can consider one end with insulator isolation corridor bus, and reason is the pars intermedia of short-circuit busbar Position has ductility for aluminium soft ribbons (5), and in the case of fixing at one end, the other end can left and right adjusting.

The present invention by the method that insulate on the spot at least saved in existing method more than half labour and when Between.And corridor bus is removed and the saving of set-up time can also reduce the probability of accident generation, improve processing emergency Certainty.
