Abstract
The invention discloses a secondary coil of a transformer of a welding machine. The secondary coil comprises a secondary coil body, and is characterized in that a plurality of hollow copper bars are spliced with one another by means of silver soldering to form the secondary coil body, 90-degree right angles are formed at corners of the secondary coil body, and a cooling channel is formed inside the secondary coil body. The secondary coil has the advantages that the transformer is compact in integral structure, accordingly, the power consumption is reduced, the efficiency is improved, the integral size of the transformer is greatly reduced, and the weight of the transformer is greatly decreased.
Description
Technical field
The present invention relates to a kind of welder transformer, especially relate to a kind of welder transformer secondary coil.
Background technology
China Patent No. is that 200720099630.4 utility model patent discloses a kind of electric resistance welding transformer secondary output coil windings device, connected and composed by secondary coil winding, bus-bar and water nozzle, it is characterized in that: the secondary coil winding is that the copper section bar of a hollow bends and forms, the two ends of this secondary coil winding weld together by the silver soldering mode jointly with the bus-bar that is used for being connected external cable, two ends at the secondary coil winding install a water nozzle respectively, have simple in structure, big, the characteristics such as internal resistance is little, good cooling results of exerting oneself.But the transformer secondary output coil windings device of this structure is because the secondary coil winding is the copper section bar of a hollow bends and form, and bending part can't form 90 degree right angles, causes the overall structure defective tightness, thereby causes magnetic flux leakage to increase, and power consumption increases, decrease in efficiency.
Summary of the invention
Technical problem to be solved by this invention provides the welder transformer secondary coil that a kind of structure is tight, low in energy consumption, efficient is high.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of welder transformer secondary coil, comprise the secondary coil body, described secondary coil body is spliced by the silver soldering of many hollow copper bars, and the corner of described secondary coil body forms 90 degree right angles and inside is formed with a cooling duct.
The two ends of described secondary coil body are respectively arranged with the bus-bar of band through hole, and described stream row is provided with water nozzle.
One end silver soldering of described secondary coil body has first bus-bar of band through hole, the other end silver soldering of described secondary coil body has second bus-bar of band through hole, described first bus-bar is provided with first water nozzle, described second bus-bar is provided with second water nozzle, and described first water nozzle is connected with described second water nozzle by described first bus-bar, described cooling duct and described second bus-bar successively.
Described secondary coil body comprises the first hollow copper bar that welds together successively, the second hollow copper bar, the 3rd hollow copper bar, the 4th hollow copper bar, the 5th hollow copper bar, the 6th hollow copper bar and the 7th hollow copper bar, silver soldering has the first perpendicular solid copper bar on described the 3rd hollow copper bar, the described first hollow copper bar, the second hollow copper bar, the 3rd hollow copper bar and the described first solid copper bar are in same plane and constitute the notched first lap of described secondary coil body, silver soldering has the second perpendicular solid copper bar on described the 5th hollow copper bar, described the 5th hollow copper bar, the 6th hollow copper bar, the 7th hollow copper bar and the described second solid copper bar are in same plane and constitute notched second circle of described secondary coil body, and described the 4th hollow copper bar links together described first lap and described second circle.
Described first bus-bar welds mutually with the described first hollow copper bar, and described second bus-bar welds mutually with described the 7th hollow copper bar.
Compared with prior art, the invention has the advantages that because the secondary coil body is spliced by the silver soldering of many hollow copper bars, the corner of secondary coil body forms 90 degree right angles, make that the overall structure of transformer is tightr, thereby reduce power consumption, raise the efficiency, and dwindled the overall volume of transformer significantly and alleviated the transformer own wt greatly; Again because the inside of secondary coil body is formed with a cooling duct, one end silver soldering of secondary coil body has first bus-bar of band through hole, the other end silver soldering of secondary coil body has second bus-bar of band through hole, first bus-bar is provided with first water nozzle, second bus-bar is provided with second water nozzle, first water nozzle is successively by first bus-bar, cooling duct and second bus-bar are connected with second water nozzle, first bus-bar and second bus-bar are directly cooled off, thereby make that the cooling effect of integrated transformers is better, guaranteed the operate as normal of transformer.
