A supporting structure of a closing resistor unit for a circuit breaker is disposed, in which the closing resistor unit is connected to a fixed portion of the circuit breaker provided in a gas insulation switchgear (GIS) to prevent a point of contact accident between a moving portion and the fixed portion. The supporting structure comprises a first supporting plate formed at a front upper end of the closing resistor unit, having one end rotatably connected to an upper end of the fixed portion at a predetermined angle back and forth and the other end rotatably connected to an upper end of the closing resistor unit at a predetermined angle back and forth; and a second supporting plate formed at a center of the closing resistor unit, having on end rotatably connected to a side of the fixed portion at a predetermined angle up and down and the other end connected to the closing resistor unit. The closing resistor unit or its joints may be prevented from being damaged from impact. |
