MOTOR BRAKING DEVICE OF GIS

摘要

A motor braking device of a GIS(Gas Insulated Switchgear) is provided to prevent damage to a limit switch and a stopper by preventing an overrun phenomenon of a motor. In a motor braking device of a GIS(Gas Insulated Switchgear), a first bevel gear(3) is formed in a shaft of a motor controlled by a motor control unit. A worm wheel(8) is formed at the lower end of an output shaft opening and closing a current of the GIS. A second bevel gear(5) enmeshed with the first bevel gear is formed at one end of the worm gear enmeshed with a worm wheel and rotating the output shaft. A limit manipulation cam(7) is formed at an upper portion of the output shaft. A limit switch(10) detects the stop timing of the motor and outputs the stop timing to the motor control unit.
