Vakuumschalter sowie System und Verfahren zu seiner Steuerung

摘要

The aim of the invention is to improve the interrupting capacity of a vacuum switch. to achieve this, the contact parts (4, 5) that can be displaced in relation to each other are separated at a variable speed. Separation takes place in such a way that during a predetermined time period a predetermined distance between the contacts is not exceeded. To prevent said predetermined distance from being exceeded, a braking element is allocated to the vacuum circuit breaker.
