Gasisolierte Schaltanlage mit einem mehrpoligen Vakuumschalter und einem mehrpoligen Lasttrennschalter

摘要

A gas-insulated switching unit has a gas-filled housing (2) containing a multi-pole vacuum switch (3) and a three-position load-break switch (5) arranged below it. Whereas the vacuum switch (3) with the horizontal position of its vacuum switching tubes (12) is arranged in such a way that the longitudinal axes are perpendicular to the front wall (13) of the housing (2), the switch shaft (41) of the load-break switch (5) is parallel to the front wall (13). Actuating rods (35), each sealed against the front wall (13) by a bellows (36) can be used to operate the vacuum switching tubes (12). The load-break switch (5) is operated by its drive device (6) via two pivoting levers (44, 47) which can be coupled by means of a fork (46).
