Title:
CURRENT LIMITING RESISTOR FOR LOAD TAP CHANGER
Document Type and Number:
Japanese Patent JP2017084867
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a current limiting resistor for a load tap changer capable of suppressing temperature rise.SOLUTION: There are provided a current limiting resistor 1 having a main body portion 101 including a coil formed of a metal having electric resistance as a material, and one and the other terminal portions 102 and 103 integrally formed at one end and the other end in the axial direction of the main body portion, respectively, the current limiting resistor 1 having a material exposed on the outer surface, and an insulation frame 3 having a pair of resistive element support portions 301 and 302 arranged opposite to each other and having a space S for disposing a part of the body portion of the current limiting resistor between the pair of resistor support portions. With a part of the body portion of the current limiting resistor 1 placed in the space of the insulating frame 3, one end portion and the other end portion are fastened to one and the other of the pair of resistor supporting portions of the insulating frame, respectively.SELECTED DRAWING: Figure 2
