Claims

[Claims for Utility Model Registration] Split type current transformation that connects split cores to form a closed magnetic circuit core with through holes, and detects the current flowing through the wire based on the change in magnetic flux generated in the closed magnetic circuit core. In the container, each of the split iron cores is molded with resin leaving the joint end surface to form a molded body, and
A split-type current transformer characterized in that a sealing agent is applied to the split end faces of the molded bodies to be integrated.
