Abstract
The utility model discloses a short circuit device of electrolytic cells. Electrolytic cells are provided with column bus bars and cathode bus bars, a short circuit soft bus bar is connected between two short circuit compression joint blocks, and the short circuit compression joint blocks are connected with cathode bus bars of two adjacent electrolytic cells, wherein a short circuit soft bus bar is composed of multilayer annealing aluminium plates with the thickness of 1 mm. The utility model can short-circuit electrolytic cells in the state of electrifying, and can complete the bus bar switching operation of stopping or starting the electrolytic cells. The utility model has the advantages of simple structure and convenient operation.
Description
Technical field:
The utility model relates to a kind of electrolyzer short circuiting device that aluminium cell is carried out short circuit.
Background technology:
Electrolyzer is the major equipment of aluminium manufacturer.An electrolytic series generally has more than 200 electrolyzer series connection.When wherein an electrolyzer can not be kept ordinary production, its short circuit need be carried out large repairs so that withdraw to produce, be called and stop groove.The electrolyzer input energising operation of fixing greatly is called fluting.Electrolyzer is when stopping groove and fluting, and the big electric current that all relates to kilo-amperes up to a hundred is converted to the operation of another part bus from a part of bus.At present, when stopping groove and fluting, need or fall electric current about more than ten minutes, dismantle or install the seal of busbar short-circuit mouth, finish the conversion operations of bus bar whole electrolytic series power failure.For increasing series of grooves number, need every year the electrolyzer number of overhaul quite a lot of, and frequent electrolytic series have a power failure or fall electric current, the disadvantageous effect of following three aspects is arranged: 1. reduced the production time, reduced aluminium output; 2. interrupt the continuous production of electrolytic series, be unfavorable for the maintenance of electrolytic process parameter; 3. having a power failure needs a series of electric operations, and electrical network is impacted.
Summary of the invention:
The purpose of this utility model is: a kind of electrolyzer short circuiting device is provided, under the state that electrolytic series does not cut off the power supply, finishes the bus conversion operations that electrolyzer stops groove and fluting, thereby save time, reduce the influence to producing; Splitter when in addition, this device also can be used as electrolyzer energising preheating and baking.
The utility model is to constitute like this: it comprises electrolyzer (6), riser bus bar (5) and negative busbar (1) are arranged on electrolyzer (6), the soft bus of short circuit (3) is connected between two short circuit crimping pieces (2), and short circuit crimping piece (2) is connected by anchor clamps (4) with negative busbar (1).
In above-described formation, a cover short circuiting device is installed in the both sides of every root post bus (5); Short circuit crimping piece (2) is connected by bolt (7) with anchor clamps (4); Soft bus of short circuit (3) and short circuit crimping piece (2) are for being welded to connect; The soft bus of short circuit (3) is made up of the thick annealing aluminium sheet of multilayer 1mm; The conductive section of the soft bus of short circuit (3) is 0.5 ~ 1 times of conductive section of every root post bus (5).
Because the interval between the negative busbar (1) of per two electrolyzers can be different, in order to adapt to different space requirements, between two short circuit crimping pieces (2), adopt the thick soft bus (3) of 1mm to connect, be very helpful.
When electrolyzer need stop the bus conversion operations of groove and fluting, short circuit crimping piece (2) is clamped on the negative busbar (1) of adjacent two electrolyzers (6) with anchor clamps (4), the electric current of electrolyzer promptly passes through the upstream electrolyzer negative busbar → soft bus of short circuit crimping piece → short circuit → short circuit crimping piece → downstream electrolyzer negative busbar, thereby makes the electric current of this electrolyzer that another reliable path arranged.In the both sides of every root post bus (5) of electrolyzer one cover short circuiting device is installed, can be guaranteed enough conductive sections.At this moment, can carry out the conversion operations of short circuit, disconnection or the connection of riser bus bar safely.After this conversion operations is finished, can remove short circuit crimping piece.
The utility model has been realized not cutting off the power supply and not falling under the state of electric current at electrolytic series, finishes the bus conversion operations that electrolyzer stops groove and fluting, has simple in structure, easy to operate advantage.It has solved short circuit mouth seal and electrolytic series has been had a power failure because of needs in when mounting or dismounting, and influence the problem of electrolyzer ordinary production, has avoided pot line to stop falling the electric disadvantageous effect that production is brought.
In addition, when the electrolyzer after newly-built electrolyzer or the overhaul puts into production, advanced person's electrical pre-heating roasting that works.Energising is during preheating and baking, in order to reduce heat-up rate, usually will use earlier less than the preheating of switching on of the electric current of its rated value.At this moment, need to insert splitter.The short circuiting device of the utility model can be used as splitter and uses.Compare with the steel splitter that uses in the past, easy to operate, structure is simpler, compact.
