摘要： A substrate includes primary side terminal holes into which the primary side terminals are inserted, secondary side terminal holes into which the secondary side terminals are inserted, and a slit disposed between the primary side terminal holes and the secondary side terminal holes. A transformer is mounted from the side of a mounting surface of the substrate. An insulating member is inserted into the slit from the side of a soldering surface of the substrate. The insulating member includes a protrusion portion that protrudes outside an area defined by virtual lines which are direct extension lines of the width of the slit to the side of the soldering surface. The protrusion portion is formed at a position more distant from the substrate than an end position of the shortest terminal of the primary side terminals and the secondary side terminals from the soldering surface of the substrate.

摘要： A single-phase three-wire type transformer which forms secondary coils by duplex coils winding two conductors in parallel according to the division intersection connection and can reduce currents circulating inside of a circuit of the transformer, thereby reducing the loss in the transformer. Coils A and B are formed in two opposing locations of a core (1). The coils A and B are configured so that two secondary coils and a primary coil are overlapped and wound in sequence from the inside of the core (1) in three layers, respectively. Each of the secondary coils provided by winding two conductors of small diameter in parallel condition on the core (1). One duplex coil connects the two parallel winding conductors in series with the other duplex coil, i.e. coils (211a) and (222b) are connected at a connection point (p), coils (212a) and (221b) at a connection point (q), coils (221a) and (212b) at a connection point (r), and coils (222a) and (211b) at a connection point (s), and the connection lines are intersected, whereby two closed circuits are formed in the secondary coils.

摘要： A ferroresonant transformer having dual outputs electrically and magnetically isolated from one another. The transformer includes a core, a primary coil on the core adapted to be connected to a source of alternating current, and two pairs of secondary windings located at axially opposite ends of the primary winding. Each of the secondary windings is coupled to the primary through a steel shunt located between the primary winding and the respective secondary winding. Each of the two secondary windings has a resonant winding associated therewith and connected to a ferrocapacitor to produce an inductive coupling. Each of the secondary windings has a pair of output terminals, each of which is connected to a separate load, with the effect that the loads are electrically and magnetically isolated from each other.
