Title:
CURRENT TRANSFORMER
Document Type and Number:
WIPO Patent Application WO/2016/019806
Kind Code:
A1
Abstract:
A current transformer, comprising a closed magnetic circuit and secondary windings. The closed magnetic circuit branches at a second part to form a plurality of branch magnetic circuits. Each branch magnetic circuit has a secondary winding formed thereon and is used as a magnetic core of the corresponding secondary winding. The secondary windings are mutually staggered in at least one direction of length, height and thickness. Multiple secondary windings are arranged in a spatially staggered manner by using unused space of the current transformer, so that total energy output by the current transformer is significantly increased and performance at small current is improved.
