Abstract
The aim of the invention is to improve the breaking ability of vacuum interrupter in the medium- and high-voltage range. Said aim is achieved whereby the contact pieces which may be displaced relative to each other are moved with a relatively high speed during a first phase (S) of the separation process until about ¼ to ½ of the ultimate separation (extinction stroke Eh) and are brought to the given ultimate separation (isolating stroke Eh) during a second phase (S) with relatively low speed.
