Abstract
The utility model pertains to a arc furnace power distribution switch of arc furnace equipment used in metallurgy industry, especially a arc furnace power distribution switch applicable to DC power supply converted from the arc furnace applicable to the former AC power supply. The technical problem to be solved exists in the background technique: the existing power arc furnace outputs AC to configure AC power supply. The characteristics of the alternating current will obstruct the current output, waste electrical energy, and result in lower efficiency of arc furnace, and influence smelting quality. The key point of the technical plan adopted for solving the problem is: a plurality of moving contacts could contact and be connected with a positive terminal or a negative terminal, and the moving contacts are connected with moving contacts wire connection terminal. The utility model could be used in the conversion from the existing AC power arc furnace to the direct current power arc furnace, and has the advantages of eliminating inductance consumption, saving electrical energy, greatly improving the arc furnace efficiency and guaranteeing the smelting quality.
Description
Technical field: the utility model belongs to smelting industry and uses a kind of arc furnace power distribution switch in the arc furnace equipment, and the eaf renovation that particularly is fit to original configuration AC power is a kind of arc furnace power distribution switch of dc power supply.
Background technology: the arc furnace of existing configuration AC power is that alternating current output is used.Obviously, because the characteristic of alternating current can produce the output of inductive obstacle electric current, the waste electric energy, and cause arc furnace efficient low, influence smelting quality.So, transform the arc furnace of original configuration AC power as the dc power supply arc furnace scientifically and rationally, be problem demanding prompt solution in the practice.
Summary of the invention: the purpose of this utility model is exactly the technical scheme that proposes a kind of arc furnace dc power supply dispense switch, the characteristic of alternating current exists with the solution background technology: owing to can produce the output of inductive obstacle electric current, the waste electric energy, and cause arc furnace efficient low, influence smelting quality.Addressing this problem the technical scheme that is adopted is: a kind of arc furnace dc power supply dispense switch, comprise positive terminal and negative terminal, and it is characterized in that some moving contacts can be connected with positive terminal or negative terminal touching, moving contact connects the moving contact binding post.Wherein, positive terminal is positioned at the centre, and negative terminal is positioned at peripheral position, forms the space that moving contact can be connected with its touching between positive terminal and the negative terminal.
The beneficial effect that the utility model and background technology comparison are had is: the AC power that has the arc furnace of configuration AC power now can be become direct current by rectifier earlier, form positive terminal and negative terminal; Realize scientifically and rationally that according to technique scheme galvanic output distributes again.Can be as required, touching is connected with negative terminal with positive terminal respectively to regulate any two moving contacts, just can form direct current and supply with a plurality of electrodes as required.Like this, solved the obstruction electric current that arc furnace the produced output of existing configuration AC power effectively, the waste electric energy has significantly improved arc furnace efficient, has guaranteed smelting quality.
Description of drawings: Fig. 1 is a schematic diagram of the present utility model.
Embodiment: with reference to figure 1, a kind of arc furnace dc power supply dispense switch comprises that 2, three moving contacts 3 of positive terminal 1 and negative terminal can be connected with positive terminal 1 or negative terminal 2 touchings, and moving contact 3 connects moving contact binding post 4.Wherein, positive terminal 1 is positioned at the centre, and negative terminal 2 is positioned at peripheral position, forms the space that moving contact 3 can be connected with its touching between positive terminal 1 and the negative terminal 2.
