Abstract
1336966 Transformers INSTITUTUL DE CERCETARE SI PROIECTARE PENTRU INDUSTRIA ELECTROTEHNICA 25 April 1972 19039/72 Heading H1T A transformer for supplying welding current has the or each primary winding 2 disposed on a core member 1 with the phase secondary winding 3 and one or more pairs 4, 5 and 6, 7 of oppositely wound interconnected coils one coil of each pair i.e. 4 or 6 being closely coupled with the primary winding and the other coil i.e. 5 or 7 being closely coupled with the secondary winding. The pairs of coils then produce an e.m.f. (which may oppose the primary voltage or aid it) due to linkage with different leakage fluxes. Also the coils of each pair may have different numbers of turns so that each pair produces an output voltage. A stop point switch 9 may be arranged to vary the number of pairs of inter-connected coils in the primary circuit to obtain a variable output. The secondary windings may be connected to a welding circuit through a rectifier group.
