Device for controlling the closing of a power circuit breaker

摘要

A device is for controlling the closing of a power circuit breaker according to operational parameters. The device includes an indication element for indicating the readiness for closing and a coupling element which interacts with the indication element. The operational parameters, for example, energy store empty or switchgear cell door open cause the indication element to pivot into the position not ready for closing and cause the coupling element to move into its disabled position. The indication element for indicating the readiness for closing and additional indication elements, which represent the position of the switching contacts and the state of the energy store, are adjacently arranged in an axial manner such that they can pivot and are provided with interacting drives in order to effect a forced drive of the indication element for indicating the readiness for closing when the position of the switching contacts or the state of the energy store does not enable or permit a closing of the power circuit breaker.
