通型零相変流器。[Claims for Utility Model Registration] (1) It has a main body shaped like a plate that houses an iron core and a winding wound around the iron core, and the main body has a through hole that passes through the primary conductor. It is characterized in that the holes have a multi-hole structure consisting of a number of holes greater than the number of the primary conductors, and each hole has a diameter that allows one conductor of each phase of the primary conductor to pass through. Feedthrough type zero-phase current transformer. (2) The through-hole has multiple rows of three holes surrounding the center of the core, and each hole in each row is one
The through-type zero-phase current transformer according to claim 1, characterized in that the transformers are formed at intervals of 20 degrees.
