Abstract

PURPOSE:To reduce an exciting electro-motive-force and to finish the second winding work in a short time, by installing a bobbin to a winding core, winding secondary windings having 2 or more turns, and inserting a primary winding into the inside of the core. CONSTITUTION:Divided bobbins 11a and 11b are installed to a winding core 10. Secondary windings 14 are formed by rotating 12 the bobbin 11 from the outside and by winding wire 13. In this method, since there is no cut-portion, the exciting electro-motive-force is small and the wire is not required to be stored. Furthermore, winding speed can be acceleraed, and an inexpensive current transformer can be obtained. For example, the current transformer can be fabricated by installing the secondary windings 14a and 14b at the portions opposite to the metal fitting 15, and inserting a primary winding 16 into an insertion hole 16.
