The Vacuum Circuit Breaker of Motor Spring Stored Energy to Apply Cam Mechanism

摘要

The present invention relates to a vacuum circuit breaker that acts as a blocking and energizing function of the main bus of the high voltage switchgear, and its purpose is to minimize the number of parts by simplifying the structure of the mechanical part and to improve safety and reliability. It is to provide a vacuum circuit breaker to achieve the performance of.;The present invention is a vacuum circuit breaker of the electric spring type, the input force generating unit consisting of an input spring is tensioned by the operation of the charging motor to accumulate the input force, and the main cam and charging installed in the rotating shaft rotated by the input spring An electric spring operation type vacuum circuit breaker is applied to a cam mechanism comprising a mechanism consisting of a cam and a driving part connected to the main contact by rotating the connecting bracket by a drive shaft provided with a breaker shaft rotating at a predetermined angle as the main cam rotates. It is to the technical point.
