Abstract
The utility model discloses a device for short circuit power failure in aluminium electrolytic tanks. The device is composed of a supporting frame (1), a heavy current switch (2), cables (3) and pressing devices (4), wherein the heavy current switch (2) is fixed to the supporting frame (1) which can be installed on an aluminium electrolytic tank; both ends of the heavy current switch (2) are respectively connected with a cable (3), and each cable (3) is connected with a pressing device (4) which can be tightly pressed on a column bus bar of the aluminium electrolytic tank. The utility model not only has the advantages that an aluminium electrolytic tank needing power failure can be short-circuited and power-cut in the power-on state of aluminium electrolytic tank series and the production of the aluminium electrolytic tank series can not be affected, but also has the advantages of safe and convenient operation, and simple structure.
Description
Technical field:
The utility model relates to a kind of device that is used for aluminium electrolytic bath short circuit power cut, and particularly a kind of device that is used under the situation that the series aluminum electrolyzer does not have a power failure aluminium cell is wherein carried out short circuit power cut belongs to the aluminium electrolytic bath short circuit power cut technical field.
Background technology:
At present, the domestic large-scale roasting aluminium cell that gives all adopts when the needs overhaul stops groove and manually opens the short circuit mouth, extracts the insulation plate, the schedule of operation of the short circuit mouth that manually closes again.Because aluminium cell riser bus bar when producing has very big electric current, therefore, such operation will cause short-circuit block and bus generation sparking phenomenon, this not only influences stably manufactured, also operator are brought potential safety hazard, also electrical network is caused huge impact simultaneously, its financial loss of bringing also is huge.In order to prevent these problems, usually require in the prior art whole electrolytic series is had a power failure or potline current is reduced to the mounting or dismounting work of finishing short circuit mouth seal after very little again.Yet, for increasing series of grooves number, need every year the electrolyzer number of overhaul quite a lot of, and frequent series stops sending electricity or potline current dropped to very lowly all can cause many difficulties to electrolysis production.Do like this, not only influenced the production in whole workshop, and because the reduction of electric current also can influence the quality of production, therefore, have in the world permitted great Chinalco do not allowed to electrolytic series have a power failure or fall that electric current implements electrolyzer stop groove short circuit operation.
Summary of the invention:
The purpose of this utility model is: a kind of device that is used under series aluminum electrolyzer switch-on regime the aluminium cell that wherein needs to cut off the power supply being carried out short circuit power cut is provided, particularly provide a kind of easy-to-operate, simple in structure and do not influence the device that is used for aluminium electrolytic bath short circuit power cut of serial electrolyzer production, to overcome the deficiencies in the prior art.
The utility model is achieved in that this device is made up of support (1), high-current switch (2), cable (3) and hold-down gear (4), high-current switch (2) is fixed on the support (1) that can be installed on the aluminium cell, be connected with cable (3) respectively at the two ends of high-current switch (2), all be connected with a hold-down gear (4) on the riser bus bar that can be pressed on aluminium cell on each cable (3).
Owing to adopted technique scheme, thereby need fall the phenomenon that electric current influences the ordinary production of series aluminum electrolyzer to the electrolytic series power failure or to the series aluminum electrolyzer when the utility model has solved the mounting or dismounting of short circuit mouth seal, this has extraordinary effect for electrolyzer stably manufactured, raising index.The utility model had both been avoided serial power failure or potline current had been dropped to the very low influence that production is brought, and can prevent the short-circuit block of aluminium electrolytic cell short-circuit port device and the phenomenon of bus generation sparking again.Therefore, the utility model compared with prior art, the utility model not only has and can be under series aluminum electrolyzer switch-on regime carry out short circuit power cut to the aluminium cell that wherein needs to cut off the power supply and not influence the advantage that the series aluminum electrolyzer is produced, but also has easy-to-operate, advantage of simple structure.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation in use.
Embodiment:
Embodiment of the present utility model: high-current switch 2 can directly adopt the high-current switch of selling on the market, about 60000～80000 amperes of the working current of this high-current switch, high-current switch 2 is fixed on the support 1 that can be installed on the aluminium cell 5, support 1 can adopt angle steel to make, two ends at high-current switch 2 connect a copper core cable 3 by welding or bolted mode respectively, all connecting a hold-down gear 4 that can connect by bolt on the riser bus bar be pressed on aluminium cell by welding or bolted mode on each copper core cable 3, hold-down gear 4 preferably is made into the constructional device of conventional bolt band pressing plate.When the aluminium cell that uses the utility model to treat power failure cuts off the power supply, preferably a high-current switch is installed for each riser bus bar of the aluminium cell of waiting to have a power failure is all corresponding, when the utility model is installed, earlier support 1 being placed in the series aluminum electrolyzer of production plant needs on the aluminium cell 5 of short circuit power cut, and make high-current switch 2 be in off-state, hold-down gear 4 on the cable 3 of high-current switch 2 one ends is connected on the riser bus bar 6 of the aluminium cell 5 that needs short circuit power cut, hold-down gear 4 on the cable 3 of high-current switch 2 the other ends is connected the downstream, and another does not need on the riser bus bar 8 of aluminium cell 7 of short circuit power cut, with high-current switch 2 closures, can realize short circuit power cut operation so then to aluminium cell 5.
In order more reliably aluminium cell being cut off the power supply, after high-current switch 2 closures, to adopt original short circuit mouth device on the aluminium cell 5 to need aluminium cell of outage to make further short circuit power cut more in the usual way and get final product this.
