Title:
POWER CONVERTER ASSEMBLY OF CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2019/146890
Kind Code:
A1
Abstract:
The present invention provides a power converter assembly of a circuit breaker capable of improving generation efficiency of a power supply current by maximizing the cross-sectional area of a core. A power converter assembly of a circuit breaker according to the present invention comprises: a plurality of power transformers for converting power from a power circuit for each phase to supply a control power; a plurality of Rogowski coils for detecting a current flowing in the power circuit for each phase; a plurality of power converter printed circuit boards having a voltage dividing circuit unit for outputting voltage-controlled current detection signals by regulating the voltage of an output of the Rogowski coil connected to a rectifying circuit unit for rectifying the output of the power transformer and outputting DC power; and an enclosure housing the plurality of power converters, the plurality of Rogowski coils, and the plurality of power converter printed circuit boards, wherein each of the plurality of power converters comprises: a power transformer core having a first through-hole portion formed on one side thereof and a second through-hole portion formed on a lower portion thereof, wherein the first through-hole portion allows a primary winding electrically connected to the power circuit for each phase to pass therethrough; the primary winding wound in a horizontal direction in the first through-hole portion of the power transformer core; and a secondary winding wound in a direction perpendicular to the second through-hole portion of the power transformer core.
