    摘要： @ A coaxially aligned transformer (60) having a secondary coil (62) wrapped with a high dielectric insulating material wrapped on a support member and slidably supported between a lock block (118) and a support base to permit the transformer electrical parameters to be adjusted by sliding the transformer core. A primary coil (58) is supported coaxially about the secondary coil (62). Both the primary (58) and the secondary coil (62) coil include voltage divider segments having equal inductance with the primary coil segments (70,72) arranged in phase and the secondary coil segments (80,82) arranged 180° out of phase. The secondary coil (62) is completely insulated and isolated from ground. The primary coil (58) has a number of taps which are connected to the contacts (142) of a multi-position switch (76) so that the voltage in one of the segments of the primary coil may be varied so that the output of the transformer may be varied. This transformer provides a switchable primary circuit and a fully insulated secondary circuit.

    摘要： A transformer circuit including a primary coil (58) with ' first (70) and second (72) voltage divider segments arranged in phase with equal inductances and a plurality of taps (74) on the second segment (72). A switch (76) is used to selectably ground one of the taps for varying the voltage impressed on the second segment (72). The transformer (60) also has a secondary coil (62) including first (80) and second (82) voltage divider segments arranged 180° out of phase and having equal inductance. The secondary coil (62) is heavily insulated, and the primary (58) and secondary (62) coils are coupled together to provide an output equal to the sum of the voltages applied to the segments of the secondary coil (62) so that the transformer output can be varied by switching from one tap to another of the second segment (72) of the primary coil (58) and that the secondary coil (62) can be heavily insulated and isolated from ground.
