<p>PROBLEM TO BE SOLVED: To provide a current transformer(CT) which does not require the working of a support member with respect to a board nor parts, such as screws, etc., for fixing the support member to the board side and the CT side. SOLUTION: This CT is provided with a core section 7, which forms a closed magnetic circuit of magnetic fluxes generated from a load current, a secondary winding 6 which is wound around the core section 7 and is interlinked with the magnetic fluxes of the magnetic circuit, and a mold insulating section 9 which covers the winding 6 and, at the same time, forms a primary conductor passing section. The CT is also provided with an elastic insulating material 11, which clamps the primary conductor in the primary conductor passing section of the mold section 9. Since the CT1 is provided with a support structure which utilizes the primary conductor, the need for a support member can be eliminated, and the number of parts can be reduced.</p> |
