WITHDRAWABLE DEVICE OF A VACUUM CIRCUIT BREAKER, CAPABLE OF PREVENTING THE CHANGE OF A LOCATION THROUGH AN EXTERNAL FORCE WHICH IS APPLIED TO A VACUUM CIRCUIT BREAKER

摘要

PURPOSE: A withdrawable device of a vacuum circuit breaker is provided to fix a first transfer part to an arbitrary position through a transfer restriction part by rotating a second transfer part only when a lever is used.;CONSTITUTION: A vacuum circuit breaker is loaded on a carriage(10). A first transfer part(20) is fixed to the carriage. A second transfer part(30) is movably installed in one side of a cradle in order to transfer a feeding force to the first transfer part. A transfer restriction part(40) selectively restricts the drive of the second transfer part. One side of the second transfer part is supported to a girder part which has both ends. The both ends are fixed to both sides of the cradle. The first transfer part is transferred in the axis direction of the second transfer part when the second transfer part is rotated.;COPYRIGHT KIPO 2011
