The high-current switch comprises static contacts and movable contacts; the movable contacts are arranged in a shaft hole and can move up and down along the shaft hole; the static contacts and the movable contacts are insulated by an insulating sleeve; and the movable contacts are driven by an oil cylinder to move up and down so as to contact and be separated from the fixed contacts. The fixed contacts are fixed on a base; a hanging lug is hung below the oil cylinder; the switch comprises two static contacts and two movable contacts; the two fixed contacts are mutually symmetrical; the two movable contacts are mutually symmetrical; conductive contact surfaces of the movable contacts are conical surfaces; conductive contact surfaces of the fixed contacts are concave conical surfaces; the conductive contact surfaces of the movable contacts coincide with the conductive contact surfaces of the fixed contacts; and the movable contacts are provided with a water-cooled loop. The high-current switch of the utility model has the advantages of simple installation, low cost and convenient operation, and the electrode bar utilization rate and the production efficiency are improved by using the high-current switch to control switching of an electrode bar group of the electric slag furnace.
Description
Technical field
The utility model relates to a kind of high-current switch, is specifically related to the high-current switch for the electroslag furnace conductive mesh.
Background technology
High-current switch applies to power industry more in the prior art, and smelting industry is rare to be related to.The traditional electrical slag hearth all is single station work, namely from the transformer to the smelting furnace, has only a cover working equipment, in smelting process, because the electrode bar residue operating time finishes when once producing inadequately, will change the electrode bar group in advance, thereby cause a large amount of wastes of electrode bar, changing the electrode bar group needs the plenty of time again, thereby has reduced production efficiency.When actual production, once proposed to be used alternatingly mutually with two cover conductive equipments, improve the utilization rate of electrode bar, thereby enhance productivity, but so a large amount of wastes that can occur equipment again.
The utility model content
The utility model purpose: the purpose of this utility model is to solve the problem of mentioning in the above-mentioned background technology, and provide a kind of high-current switch is applied to electroslag furnace, with the switching of lower cost realization electrode bar group, thus the technical scheme of enhancing productivity.
Technical scheme: electroslag furnace high-current switch described in the utility model comprises and decides contact and moving contact; Moving contact is located in the axis hole and can moves up and down along axis hole; Decide to insulate with insulating case between contact and the moving contact; Moving contact moved up and down by hydraulic oil cylinder driving to realize with the contact of deciding contact with separate.
Describedly decide contact and be fixed on the base; Described oil cylinder below hangs with hanger; Describedly decide contact and moving contact is respectively 2; Decide contact symmetry each other for described 2; 2 moving contacts are symmetrical each other; The conductive contact surfaces of moving contact is the conical surface; The conductive contact surfaces of deciding contact is the conical surface of spill; The conductive contact surfaces of described moving contact matches with the conductive contact surfaces of deciding contact; The conical surface that coincide has increased the contact contact area mutually, makes switch have better electric conductivity; Establish water cooling labyrinth on the moving contact, increased ampacity, reduced energy consumption.
Operation principle of the present utility model is: thus oil cylinder drives the piston motion and drives the moving contact that links to each other with hanger and move up and down by passing in and out oil.Owing to decide contact and fix, moving contact move up and down will with decide contact and contact or separate.High-current switch conduction during contact, high-current switch outage during separation.
Beneficial effect: high-current switch of the present utility model install simple, cost is lower, easy to operate, the switching of the electrode bar group by high-current switch control electroslag furnace has improved the utilization rate of electrode bar, has also improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of high-current switch.
Embodiment
Below in conjunction with accompanying drawing, technical solutions of the utility model are described, but protection range of the present utility model is not limited to described embodiment.
As shown in Figure 1, oil cylinder hangs with hanger 56 times, hanger 5 links to each other with moving contact 4, moving contact 4 is positioned at axis hole, drive moving contact 4 by oil cylinder 6 and in axis hole, move up and down, decide contact 1 and be fixed on the base 3, the conductive contact surfaces 7 of taper is arranged on the moving contact 4, decide to have on the contact 1 conductive contact surfaces 8 of concave conical surface, the conductive contact surfaces 7 of moving contact 4 matches with the conductive contact surfaces 8 of deciding contact 1.
High-current switch of the present utility model by oil cylinder 6 control moving contacts 4 with decide contact 1 and whether contact conduction, be specially: oil cylinder 6 is by 4 risings of hanger 5 drive moving contacts, moving contact 4 with decide contact 1 and separate, high-current switch is in off-position; Oil cylinder 6 drives moving contact 4 by hanger 5 and descends, and moving contact 4 more and more closely contacts with the conductive contact surfaces 8 of deciding contact 1 until the conductive contact surfaces 7 of moving contact 4 with the distance of deciding contact 1, and during contact, high-current switch is in "on" position.In order to guarantee that moving contact 4 fully contacts with deciding contact 1, preferably, the conductive contact surfaces 7 of moving contact 4 matches with the conductive contact surfaces 8 of deciding contact 1.
