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.
Claims4
A supporting structure including a closing resistor unit for a circuit breaker, the closing resistor unit being 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 comprising:
- a first supporting plate connected at a front upper end of the closing resistor unit, having one end rotatably connected to an upper end of the fixed portion and another end rotatably connected to an upper end of the closing resistor unit;
- and
- a second supporting plate connected at a center of the closing resistor unit, having one end rotatably connected to a side of the fixed portion and another end connected to the closing resistor unit.
