Abstract
Provided is a welding single phase transformer, comprising a primary winding, a secondary winding, an iron core and a clamping piece, wherein the iron core is in three-core column structure, the primary winding and the secondary winding are sleeved on the middle core column of the iron core, the secondary winding is formed by casting and a water cooling cycle pipe is built-in the secondary winding. Because the secondary winding is formed by casting at one time and cooled with strong water, the heat dispersion is improved, the mechanical intensity is improved, the process is simple and the size is decreased.
Description
Technical field
The utility model relates to welding transformer, be applicable on the welding machine single-phase transformer.
Background technology:
Welding transformer is a vitals on the welding machine, and present welding transformer often is from the cooling of cold-peace high wind, has caused the increase of welding transformer size like this.For reducing the size of welding transformer, also there is pair secondary coil to adopt water-cooled structure, secondary coil is copper pipe welding, this construction machine intensity difference, and shortcoming such as assembling is inconvenient, and cooling effect is not good.But its needs of present welding machine because of automation control, size often can not be excessive, give design, operation, use and make troubles, and adopt that strong water cooling, its electric conductivity improve more, overall dimensions reduce relatively, the bigger enhancing of its reliability, output current be more stable.
The utility model content
The purpose of this utility model is the deficiency that overcomes prior art, and a kind of simple in structure, reasonable in design, easy for installation, operation is simple, mechanical strength is high, volume is little welding single-phase transformer is provided.
The technical scheme that technical problem adopted that solves is: a kind of welding single-phase transformer comprises winding, secondary winding, iron core and folder one time, iron core is three stem stem structures, winding and secondary winding are set in the iron core on the stem stem, it is characterized in that the secondary winding casting forming, in establish the water cooling circulating line.Because the secondary winding casting forming, mechanical strength is good.
During concrete enforcement, the leading-out terminal of secondary winding is provided with water nozzle, and water nozzle and water cooling circulating line communicate, and the leading-out terminal one of secondary winding is cast with line bank.The leading-out terminal water nozzle is the port into and out of cooling water, because the leading-out terminal one of secondary winding is cast with line bank, line bank can be connected with outside by lug plate, need not weld, and operation is simple.
The beneficial effects of the utility model are: because secondary winding and line bank are a casting forming, pass to strong water cooling, heat dispersion improves, and mechanical strength improves, and operation is simple, and size reduces.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the schematic diagram that the utility model embodiment master looks;
Fig. 2 is the schematic diagram that the utility model embodiment left side is looked.
Among the figure 1, iron core 2, winding 3, folder 4, secondary winding 5, fastening screw 6, insulation board 7, water nozzle 8, left line bank 9, right line bank 10, bolt
Embodiment:
As shown in Figure 1, 2, a kind of welding single-phase transformer, comprise winding 2, secondary winding 4, iron core 1 and folder 3 one time, the square three stem stem structures that iron core 1 is made into for high-quality silicon steel sheet, forward and backward folder 3 is fixedly clamped iron core 1 by bolt 10, and winding 2 and secondary winding are set in the iron core 1 on the stem stem, insulate with insulation board 6 between winding 2 and the secondary winding 4, and fixing by fastening screw 5, its outlet terminal is in the both sides of transformer body respectively; Secondary winding 4 casting formings, the left and right leading-out terminal of secondary winding 4 one respectively is cast with left line bank 8 and right line bank 9, in establish the water cooling circulating line, the left and right leading-out terminal of secondary winding 4 is provided with water nozzle 7, water nozzle 7 and water cooling circulating line communicate, and leading-out terminal water nozzle 7 is the port into and out of cooling water, and cooling water circulates in secondary winding 4 internal flows by water nozzle 7, to reduce the temperature rise of secondary winding 4, improve electric property.
Claims (2)
1. a welding single-phase transformer comprises winding, secondary winding, iron core and folder one time, and iron core is three stem stem structures, and winding and secondary winding are set in the iron core on the stem stem, it is characterized in that the secondary winding casting forming, in establish the water cooling circulating line.
2. a kind of welding single-phase transformer according to claim 1 is characterized in that the leading-out terminal of above-mentioned secondary winding is provided with water nozzle, and water nozzle and water cooling circulating line communicate, and the leading-out terminal one of secondary winding is cast with line bank.
