Abstract
The invention discloses a closing iron core used for a high-voltage breaker. The closing iron core comprises an iron core body. The right portion of the iron core body is a hollow cylindrical structure, and the left portion of the iron core body is a solid cylindrical structure. The hollow cylindrical structure is equipped with a plurality of stepped grooves, and the right end surface of the hollow cylindrical structure is equipped with a plurality of through holes. The closing iron core used for a high-voltage breaker will not cause short circuit of a closing coil while working, and thus a phenomenon that the high-voltage breaker cannot be closed is avoided. Moreover, the phenomenon that the high-voltage breaker cannot be closed is avoided because the closing iron core is large in over stroke, and the working effects of the high-voltage breaker are ensured.
