Abstract
The utility model discloses a device which is directly welded and connected between two conductive components, particularly a copper-aluminum transition joint. The copper-aluminum transition joint comprises a copper bar and an aluminum bar, and one end of the copper bar is inserted into a hole on one end of the aluminum bar and is welded with the aluminum bar. The usage of the copper-aluminum transition joint can greatly reduce the fault of the joint point; the usage can be safe, and the yield can be improved. Simultaneously, the copper-aluminum transition joint can also reduce energy consumption, and the copper-aluminum transition joint is suitable for industrial departments which conduct the production through adopting the DC high current.
Description
The utility model relates to a kind of line connector, is the device that direct welding connects between two conductive components, specifically a kind of copper-aluminium transition joint.
The industrial department that uses D.C. high-current to produce as aluminium manufacturer, carbon element factory etc., must use powerful direct current to carry out electrolysis or the high heat of generation in process of production.The copper bar that uses generally adopts screw to be connected with aluminium row's jointing at present, and this copper-aluminium joint is when transmitting powerful electric current, because the galvano-cautery effect makes its loose contact, arc is beaten in junction heating easily, causes stopping production, has a strong impact on ordinary production.
The purpose of this utility model is: the copper-aluminium transition joint that a kind of safety, low energy consumption are provided.
The technical solution of the utility model is: large-scale copper-aluminium transition joint comprises copper bar and aluminium row, and an end of copper bar inserts aluminium and arranges in the hole of an end, with aluminium row welding.Copper bar inserts on that end side surface of aluminium row groove, can one on the side, on two sides, on three sides or on four sides groove is arranged.The cross section of groove is garden arc, triangle etc.
The utility model has the advantages that: use this large-scale copper-aluminium transition joint can significantly reduce the fault of joint, thereby improve output, also greatly reduce energy consumption simultaneously, increase economic efficiency.Show that according to inventor's situation of the present utility model on probation on a cover graphitizing furnace group of Nantong Carbon Factory its advantage is conspicuous.Before trial edition utility model not, 92 years 13 stoves that are out of order, 85 times, wherein a stove has a power failure altogether to swing in 58 hours and repaiies because of main busbar fault, causes in addition the 45000KWH electric weight not send and just is forced to the blowing out end, has had a strong impact on the product quality of this stove.Another stove was swung because of the common blowing out of main busbar fault and is repaiied in 76 hours, then added electric 70000KWH.Added electric 94300KWH because of main busbar fault is total to blowing out 80 hours in 93 years, the burner fault was stopped 231 hours altogether, added electric 172000KWH.After 94 years began to reequip the trial edition utility model, fault did not take place in main busbar.Show from above result, the utlity model has obvious safe fault-free effect.Secondly, adopt the utility model joint to replace original copper aluminium to connect, can significantly reduce the energy consumption of joint.Through surveying: every production one hearthstone electrode ink, at the original consumes power 2104KWH in this joint, only consume 20KWH after the transformation; And every production one hearthstone China ink anode at the original consumes power 1954KWH in this joint, only consumes 18KWH after the transformation.As seen transform back loss electric weight and be less than original 1%.Calculate by annual product graphite electrode 75 stoves and graphite anode 35 furnace gauges, but 1 year save power is: (2100-20) * 75+(1954-18) * 35=224000KWH.According to measuring and calculating, only a place joint is transformed, and is annual because of economize on electricity, and few economic benefit of being produced of stopping production is about 200,000, as seen the utlity model has tangible economic benefit.
