Abstract
The utility model discloses a secondary coil of a transformer of a welding machine. The secondary coil of the transformer of the welding machine comprises a secondary coil body. The secondary coil of the transformer of the welding machine is characterized in that the secondary coil body is formed by a plurality of hollow copper bars in a silver soldering and splicing mode, a 90-degree right angle is formed on each corner of the secondary coil body, and a cooling channel is formed in the secondary coil body. The secondary coil of the transformer of the welding machine has the advantages that due to the fact that the integral structure of the transformer can be more compact, power consumption is reduced, efficiency is improved, the integral size of the transformer is greatly reduced, and the weight of the transformer is greatly reduced.
Description
Technical field
The utility model relates to a kind of welder transformer, especially relates to a kind of welder transformer secondary coil.
Background technology
China Patent No. is that 200720099630.4 utility model patent discloses a kind of secondary coil winding apparatus of electrical resistance welding transformer, 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 for being connected external cable, two ends at the secondary coil winding are fixedly mounted with respectively a water nozzle, have simple in structure, large, the characteristics such as internal resistance is little, good cooling results of exerting oneself.But the copper section bar that the transformer secondary output coil winding apparatus of this structure is a hollow due to the secondary coil winding bends and forms, 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 in the utility model is to provide a kind of close structure, the welder transformer secondary coil that low in energy consumption, efficiency is high.
The utility model 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 with through hole, are provided with water nozzle on described stream row.
One end silver soldering of described secondary coil body has the first bus-bar with through hole, the other end silver soldering of described secondary coil body has the second bus-bar with through hole, be provided with the first water nozzle on described the first bus-bar, be provided with the second water nozzle on described the second bus-bar, described the first water nozzle is connected with described the second water nozzle by described the first bus-bar, described cooling duct and described the 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, on described the 3rd hollow copper bar, silver soldering has the first perpendicular solid copper bar, described the 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 form the notched first lap of described secondary coil body, on described the 5th hollow copper bar, silver soldering has the second perpendicular solid 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 form notched the second circle of described secondary coil body, described the 4th hollow copper bar links together described first lap and described the second circle.
Described the first bus-bar welds mutually with described the first hollow copper bar, and described the second bus-bar welds mutually with described the 7th hollow copper bar.
compared with prior art, the utility model has the advantage of 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 the overall structure of transformer tightr, thereby reduce power consumption, raise the efficiency, and significantly dwindled the overall volume of transformer and greatly alleviated the transformer own wt, inside due to the secondary coil body is formed with a cooling duct again, one end silver soldering of secondary coil body has the first bus-bar with through hole, the other end silver soldering of secondary coil body has the second bus-bar with through hole, be provided with the first water nozzle on the first bus-bar, be provided with the second water nozzle on the second bus-bar, the first water nozzle is successively by the first bus-bar, cooling duct and the second bus-bar are connected with the second water nozzle, carry out directly cooling to the first bus-bar and the second bus-bar, thereby make the cooling effect of integrated transformers better, guaranteed the normal operation of transformer.
