Abstract
The utility model discloses a conducting system for a submerged arc furnace combined holder. The conducting system comprises even number of groups of conductive copper tubes and two busbars, wherein each of the busbars is electrically connected with half number of the conductive copper tubes. The conducting system disclosed by the utility model can enable current distribution to be more uniform, and reduces faults in using equipment.
Description
Technical field
The utility model relates to the hot stove in ore deposit, relates in particular to the conducting system of the hot stove composite electrode holder in ore deposit.
Background technology
There is the current density problem bigger than normal on the unbalanced and electrode shell gusset of CURRENT DISTRIBUTION in the conducting system that the hot stove in existing ore deposit is controlled device; so it is excessive through the heat that regular meeting produces certain a slice or a few plate electrode shell gusset; burn out contact element, cause equipment fault, influence ordinary production.
The utility model content
The utility model purpose: the purpose of this utility model provides the conducting system that a kind of CURRENT DISTRIBUTION is uniform, reduce the hot stove composite electrode holder in ore deposit of operational failure.
Technical scheme: the conducting system of the hot stove composite electrode holder in ore deposit of the present utility model comprises even number set contact tube and two bus-bars, and each bus-bar is electrically connected with the contact tube of half quantity.
Described contact tube is 14 groups, and each bus-bar is electrically connected with 7 groups of contact tubes, and described bus-bar is the copper bus-bar.Per 7 groups of contact tubes are point-blank evenly distributed.Described bus-bar is divided into the first current collection unit and the second current collection unit, and it is semicircular groove that the described first current collection unit and the second current collection unit arrange cross section accordingly.Contact tube in the middle of being positioned at is communicated with cooling water pipe, and all the other contact tubes are connected with water-cooled cable.The conducting system of the hot stove composite electrode holder in this ore deposit comprises that also 14 windings touch element.The outer surface of the described first current collection unit and the second current collection unit is provided with insulation board.
Operation principle: since the effect of bus-bar, the electric current distributed uniform when energising on the contact element, thus avoided some contact element to be burnt out.
Beneficial effect: the utility model compared with prior art, its remarkable advantage be make on the contact element CURRENT DISTRIBUTION more all with, reduced equipment fault.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of bus-bar;
Fig. 3 is the enlarged diagram of a-quadrant among Fig. 2.
Embodiment
As shown in Figures 1 to 3, the conducting system of the hot stove composite electrode holder in ore deposit of the present utility model comprises 14 groups of contact tubes 1, and wherein 7 groups are electrically connected fixing by T2 copper bus-bar 2.Contact tube 11 in the middle of being positioned at is communicated with cooling water pipe, and all the other contact tubes are connected with water-cooled cable.Bus-bar 2 is divided into the first current collection unit 21 and the second current collection unit 22, and it is semicircular groove 23 that the described first current collection unit 21 and the second current collection unit, 22 minute surfaces arrange cross section symmetrically.When with stud 3 with the first current collection unit and Unit second fixedly the time, passage that cooperates with contact tube of semicircular groove 23 formation.
Outer surface in first, second current collection unit is provided with insulation board 4.Add two block pressur plates 5 and two packing rings 7 during bolt successively, outermost packing ring is insulating washer.The outer end of bolt is provided with insulating sleeve 6.
The transformer of the hot stove in ore deposit of 12 groups of conducting elements and outer short_net copper pipe, water cooling cable remain unchanged, and still every phase is 12 groups, and conducting element is increased to 14 groups of every phases, and corresponding contact tube and feed copper pipe are according to 14 groups of couplings.Because being touched element, original 12 windings are increased to 14 groups of every phases, 6 contact tubes of the corresponding connection of 6 water-cooled cables on every limit, and middle contact tube (corresponding contact element is near the trigonum) directly is communicated with cooling water.Current density ratio on the electrode shell gusset had reduced by 14% originally.Increase the bus-bar of copper (T2) simultaneously at contact tube, make 14 windings touch the electric current distributed uniform on the element.The rubescent burning of electrode shell gusset has been avoided in above-mentioned improvement, thereby solved the problem that burns out contact element, failure rate greatly reduces, the conducting system transformation of the furnace of calcium carbide composite electrode holder of 2 30MVA that we finish, the operating rate of electric furnace is brought up to more than 98% from about 94%, and output increases more than 5%, and power consumption reduces more than 6%, result of use is very good, has vast market prospect.
