Collector rail terminal for gas-encapsulated MV switch appts.

摘要

The collector rail terminal is provided by a cross-piece (SSK) coated on the outside with an earth metallisation (ELS), with an internal space receiving a guide sleeve (DBU) for a conductor bolt (DBO). The contact bolt is brought into contact with the collector rail (SS1,SS2) fitting through the cross-piece by a contact screw (KTS), with a closure bung (VSS) in opposition to the conductor bolt. The closure bung has a peripheral outer element (VRR) and a threaded bore (GWB), providing a sealed cover for the contact screw upon elastic deformation of the cross-piece.
