Abstract

A metal-encapsulated and gas-insulated load switching device has a three-position switch (4) for the 'on', 'off' and 'earthed' positions and a vacuum power switch. Here, with the three-position switch (4) in its 'on' position, there is a series connection with the vacuum power switch (11) such that the three-position switch (4) is connected to the busbar side and the vacuum power switch (11) to the output side. The output side is directly earthed with the three-position switch (4) in the 'earthed' position. In this circuit, short-circuit currents are contolled without any additional interlocks as there is a three-position switch designed as a load separating and earthing switch which is also capable of switch-on on a short circuit. The space provided for the vacuum switching tubes (12) can be of such a size that fuse chambers can also be used for HCBC fuse inserts. It is thus possible to create modular units of the same size with different switchgear for the most common switching purposes.
