Non-Inductive Winding Wire-Type Solenoid Bobbin

Abstract

Disclosed herein is a non-inductive winding wire-type solenoid bobbin. The bobbin includes a cylindrical bobbin body, winding grooves formed on an outer circumferential surface of the bobbin body at regular intervals, and a connection channel provided on one side of each of the winding grooves. According to the present invention, an inner wire is in direct contact with liquid nitrogen through the connection channel, thus increasing the cooling effect when an electrical power system experiences trouble, and a superconducting fault current limiter including the bobbin limits a current, therefore minimizing damage to the inner wire, and makes a fast recovery after the fault current is limited to allow the current to resume flowing in the system.
