ABSTRACT:
A noise-shielded transformer which suppresses electrical noises by absorbing conductible electrical noises that flow into the power line to cause interference, consisting of a gapless-type toroidal core, a primary winding and a secondary winding uniformly wound after dividing the entire magnetic path of the toroidal core in two, and conductive plates mounted to wrap the primary winding and secondary winding, respectively, wherein conductive plates are mounted in the gap of the toroidal core to magnetically isolate the primary winding and the secondary winding, conductive plates are mounted outside the gap of the toroidal core and the gapless-type toroidal core has a configuration of continuously winding steel shield of directional silicon.
