Abstract
The utility model relates to an insulation connection structure between a conductive cross arm of an electric arc furnace and an electrode lifting column. In a high temperature state, when current passes through the conductive cross arm, the deposited conductive powder generate an arc between a bolt and the electrode lifting column so that the bolt and the electrode lifting column are burned out.And the production is stopped for maintenance. The insulation connection structure provided by the utility model comprises the electrode lifting column, the conductive cross arm, the bolt and an insulation nut. An insulation plate is provided between the conductive cross beam of the electric arc furnace and the electrode lifting column. Furthermore the conductive cross beam of the electric arc furnace and the electrode lifting column are connected through a bolt. The bolt is sleeved with an insulation gasket, an insulation pad and a washer which are fixed through a nut. The utility model is characterized in that: the bolt adopts a stud bolt; and furthermore two ends of the bolt are sleeved with insulation nuts for insulating the conductive cross beam from the electrode lifting column. According to the utility model, based on the connection structure, the connection bolt adopts the stud bolt. An insulation nut is respectively added at two ends so that the conductive cross arm is totallyinsulated from the electrode lifting column. The problems of current leakage and arc generation of the connection bolt are effectively settled.
Description
Technical field
The utility model belongs to the annex of electric arc furnaces, is specifically related to the insulation syndeton of a kind of electric arc furnaces conductive cross arm and rise fall of electrodes column.
Technical background
In the prior art, when the electric arc furnaces conductive cross arm is connected with the rise fall of electrodes column, pass through the rise fall of electrodes column, be provided with insulation board between the two, and link together with screw bolt and nut in order to prevent the electric current on the conductive cross arm.Be with insulation sleeve and felt pad on the bolt.In actual smelting process, owing to contain a large amount of conduction dust in the electric arc furnaces flue dust, be deposited on bolt, nut and conductive cross arm and rise fall of electrodes column surface, under the condition of high temperature when conductive cross arm power on the circulation out-of-date, the conduction dust of deposition, the starting the arc burns out bolt and rise fall of electrodes column between bolt and rise fall of electrodes column, causes the maintenance that stops production.
The utility model content
The insulation syndeton that the technical problem that the utility model solved provides a kind of electric arc furnaces conductive cross arm and rise fall of electrodes column can solve the problem of the connecting bolt electric leakage starting the arc effectively.
For solving above-mentioned technical problem, the technical scheme that the utility model is taked:
The utility model comprises rise fall of electrodes column, conductive cross arm, bolt, insulation nut, is provided with insulation board between the conductive cross arm of electric arc furnaces and the rise fall of electrodes column, and connects by bolt; Described bolt sleeve is provided with insulation sleeve, felt pad, packing ring and fixes by nut, and its special character is: described bolt adopts stud, and at its two ends sheathed insulation nut with conductive cross arm and the isolation of rise fall of electrodes column.
Compared with prior art, the utility model requires connecting bolt to adopt stud on the basis of syndeton, two has increased the insulation nut respectively, makes the isolation of insulating fully of conductive cross arm and rise fall of electrodes column, has solved the problem of the connecting bolt electric leakage starting the arc effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model comprises: rise fall of electrodes column 1, insulation board 2, conductive cross arm 3, insulation sleeve 4, stud 5, felt pad 6, packing ring 7, nut 8, insulation nut 10; Be lined with insulation board 2 between conductive cross arm 3 and rise fall of electrodes 1 column.
In actual smelting process, owing to contain a large amount of conduction dust 9 in the electric arc furnaces flue dust, be deposited on bolt, nut 8 and conductive cross arm 3 and rise fall of electrodes column 1 surface, under the condition of high temperature when conductive cross arm 3 power on the circulation out-of-date, the conduction dust 9 of deposition, the starting the arc burns out bolt and rise fall of electrodes column between bolt and rise fall of electrodes column, the utility model adopts stud 5 to connect, be with insulation sleeve 4 on the stud, after felt pad 6 and packing ring 7 usefulness nuts 8 compress, put insulation nut 10 at bolt two, make the isolation of insulating fully of conductive cross arm and rise fall of electrodes column, solved the problem of the connecting bolt electric leakage starting the arc effectively.
