Abstract: Disclosed is a supporting structure of a closing resistor unit for a circuit breaker which connects the closing resistor unit to the fixed portion through the first supporting plate and the second supporting plate to allow the closing resistor unit to move back and forth with respect to the fixed portion through the first supporting plate and to move up and down with respect to the fixed portion through the second supporting plate, whereby the closing resistor unit or its joints may be prevented from being damaged from impact.

Abstract: The present invention relates to a supporting structure of a closing resistor for a high voltage circuit breaker, capable of stably supporting the closing resistor not to be twisted even by an impact applied upon a closing operation. A supporting structure of a closing resistor for a high voltage circuit breaker according to one embodiment includes a fixed part main circuit conductor, a supporting conductor installed on an upper surface of the fixed part main circuit conductor, a connecting conductor connected to one end of the supporting conductor, a closing resistor unit coupled to one side of the fixed part main circuit conductor in a spaced manner, and a coupling conductor provided to couple the supporting conductor to the closing resistor unit. The supporting conductor and the connecting conductor are provided with a coupling rib and a coupling groove, respectively, to be coupled to each other in an inserting manner.
