Abstract (en)
To provide a compact transformer utilizing a transformer core of a reduced size and incapable of being heated to a temperature equal to or higher than a prescribed temperature limit, the transformer includes a transformer core (18), primary and secondary windings (13, 14) wound around the transformer core (18) in axially spaced relation to each other, and a temperature responsive switch (30) electrically connected in series with the primary winding (13). The switch (30) is adapted to be turned off in response to increase of the temperature over a predetermined value and is positioned between the transformer core (18) and one of the primary and secondary windings (13, 14). <IMAGE>
