APPARATUS FOR PREVENTING SEPARATION OF MECHANISM PART IN VACUUM CIRCUIT BREAKER

摘要

PURPOSE: An apparatus for preventing separation of a mechanism part in a vacuum circuit breaker is provided to reduce damages of each part of the vacuum circuit breaker by preventing the separation of the mechanism part when the vacuum circuit breaker is inserted and operated. CONSTITUTION: One side of an elastic spring(410) is fixed to an upper portion of a horizontal moving plate(334) by a bolt. The other side of the elastic spring(410) is fixed to an upper portion of a casing(338) by a bolt. The elastic spring(410) provides force of restitution to the horizontal moving plate(334) when the horizontal moving plate(334) is moved to one direction. A roller(420) is installed at a right side of the elastic spring(410). The roller(420) can be rotated on an upper portion of the horizontal moving plate(334). An operating pin(340) is inserted into a guide frame(341). An incline block(430) having an incline plane(431) is fixed to an intermediate portion of the operating pin(340). A coil spring(342) is installed around the operating pin(340).
