Problems solved by technology

Now most factories use gas welding to connect wires. During gas welding, thin wires are easy to fuse, but it takes a long time for thick copper flat wires to melt. It is not easy to control, and the operation time is relatively long, which wastes man-hours.

Abstract

The invention relates to a low-voltage welding transformer and an operation method thereof. The low-voltage welding transformer comprises two groups of transformer winding components which are the same in structure, and each transformer winding component comprises an iron core, a primary winding and a secondary winding, wherein each primary winding and the corresponding secondary winding are arranged outside the corresponding iron core; primary windings in the two groups of transformer winding components are in series connection, and each primary winding is coupled with the corresponding secondary winding in the transformer windings; two circuits of output ends are led out of two secondary windings; the two circuits of output ends led out of the two secondary windings respectively are connected correspondingly, so that the series connection output or parallel connection output of the two secondary windings is formed.

Description

technical field [0001] The invention relates to a transformer, in particular to a low-voltage welding transformer and an operating method thereof. Background technique [0002] At present, the production process of the domestic transformer or motor industry is roughly the same. In the process of winding the coil, since the weight of the wire on the reel is certain, and winding a coil often requires several coils of wire, it is necessary to wind the coil. Connect wires from different reels. Now most factories use gas welding to connect wires. During gas welding, thinner wires are easy to fuse, but it takes a long time for thick copper flat wires to melt. A welding transformer capable of outputting stable current is needed to improve welding quality and shorten working hours. Contents of the invention [0003] The object of the present invention is to provide a low-voltage welding transformer and its operation method. The output terminals of the secondary windings are draw...
