WINDING-UP METHOD FOR WINDING UP ENERGY STORING SPRING IN DRIVE MECHANISM OF HIGH VOLTAGE OR MEDIUM VOLTAGE CIRCUIT BREAKER, AND CIRCUIT BREAKER FOR CONDUCTING THE WINDING-UP METHOD

摘要

PURPOSE: To facilitate winding work in the case of no winding-up motor or in the case of power feeding interruption, and also wind up more quickly than using time of a manual crank handle. ;CONSTITUTION: Among power tools 7 on the market driven by motors, the power tool 7 equipped with a drive tool element 9 is utilized for winding up an energy storing spring. In a circuit breaker suitable for conducting the above method, an end portion 3 formed into bolt head-like is provided on the drive shaft 2 of a drive mechanism 1, and the energy storing spring is wound by the rotation drive of the drive shaft 2.;COPYRIGHT: (C)1994,JPO
