Abstract
Be used to compensate the layout from harmful electromagnetic interference of the milking cell field of the milking cell of potline and rectifier field, this pot line comprises at least two row's reduction cells (1 and 2), and each is arranged battery and is laterally and arranges.Article three, the electric current more than in the power source bus of asymmetric layout (T) is through the distribution bus (A on each milking cell, B, C, D) conduct to milking cell, and flow out from milking cell, make on distribution bus, to form net current, thereby the magnetic interference from rectifier field and milking cell field is afforded redress.
Description
The present invention relates to be used to compensate the layout from harmful electromagnetic interference of the milking cell field of the milking cell of potline and rectifier field, potline comprises at least two row's reduction cells, and every row's battery is transversely arranged.
Utilizing electric energy with efficient manner is crucial for the production economy of aluminum electrolysis process.Electric current first electrolytic cell from rectifier guiding one row, be close to first battery of a row from last battery guide of this row, it also is crucial how being provided with from the various piece of the bus device of last battery guide rectifier then, with so that the inducedmagnetic field in the battery reduces to the most weak.
A kind of typical layout of aluminium electrolysis cell is that each row's battery is laterally placed, and electric current is directed to next battery from a battery, and from next row of row's guiding.Current opposite in direction during the sense of current among one row is arranged with contiguous one.
Electrolysis tech of the present invention utilizes 200 to 300KA electric current.This electric current can induce the big magnetic field of adjacent row of influence or adjacent cell and cause various serious problems, because magnetic field can hinder the molten metal of the negative electrode that forms each battery bottom.Molten metal can be subjected to owing to electric current flows through the electromagnetic force that produces.
, the distance between two row's batteries of pot line is all longer usually, makes the vertical component of having only magnetic field have an effect to a contiguous row.For compensate by a contiguous row caused deleterious be the biased field component, it is big to wind the electric current of other parts that the current ratio that promptly flows through in this weak point is held towards vicinity one row's of transversely arranged electrolytic cell short end flows to battery usually.
First of each row is the battery that is subjected to disturbance of electromagnetic field maximum with last battery (milking cell), because they are subjected to the magnetic field from a contiguous row, and from electric current is conducted back rectifier from an end of pot line scope, and on the other end electric current is transmitted to the interference in magnetic field of next row's (between the milking cell) bus from a row.By the distance between increase rectifier and the pot line, and increase last battery to distance of electric current being guided into the contiguous one horizontal bus of arranging from a row can weaken this interference., owing to need long bus and bigger place, this is the method for a costliness.
The objective of the invention is to reach abundant compensation to the magnetic interference of the terminal field of the milking cell of the pot line formed from the rectifier field and by aluminium cell row, another purpose then is to lower assembly cost by reducing bus length, and by reducing the distance between rectifier and pot line one end, and the distance between the horizontal bus and the pot line the other end and saving space.
By make electric current in three above power source buss, be transmitted to the milking cell of pot line or just can achieve the above object asymmetricly from this milking cell outflow, produce net current in order to induction in distribution bus, thereby to recompensing from the magnetic interference of rectifier and terminal field.
The present invention is only by example, comprise with reference to expression layout of the present invention pot line accompanying drawing and at length introduce.The present invention includes only the milking cell in row's battery, and does not comprise full row's battery.To be appreciated that in addition, adopt well-known technology, just can make each row in essence with respect to being stabilized from the interference of adjacent row.
Electric current from rectifier L is to be transported to first first milking cell of arranging with three above power source buss, and power source bus is connected to the distribution bus A that founds bus S more than four that comprises with respect to the battery symmetric arrangement then asymmetricly.This layout has just provided the net current that conducts from right to left in power source bus, and first milking cell of first row is afforded redress.Thereafter, electric current is transmitted to the resistance utmost point of adjacent downstream battery from the negative electrode of upstream battery, conducts to another milking cell of first row usually.
Electric current conducts to distribution bus B from this another milking cell.Electric current ranked first a battery from described battery through conducting to along second of the being seen vicinity of the sense of current with Up Highway UHW T with respect to three of the asymmetric setting of power source bus mid point then.This layout has from left to right provided net current in distribution bus B, and provides essential extra compensation to this another milking cell of first row.
Electric current is further conducted to the second distribution bus C that ranked first on the battery asymmetricly.Its after-current conducts to the anode of adjacent downstream battery from the negative electrode of upstream battery, conducts to another milking cell of second row usually.Electric current conducts to distribution bus D from this another milking cell of second row.As shown in the figure, electric current is again from this bus D, gets back to rectifier through conducting with Up Highway UHW T with respect to three of the asymmetric layout in center of distribution bus.
Obviously, be in the distribution bus among rectifier field and terminal, the size of upright bus and power source bus and position will determine the strength of current in the distribution bus, and to the degree of compensation of milking cell.
About considering that actual arrangement of the present invention is utilized normal building process and realized for building and plan has high current intensity and very important various factors and condition during the potline in the magnetic field of weakening.Usually the milking cell that has only electric current to surpass the pot line of 200KA just needs extra compensation.
