    摘要： An electric switch having an axially movable switching contact and a resilient annular fixed contact. The fixed contact is in permanent contact with said switching contact and consists of a zigzag folded metal strip surrounded and supported by an annular holder. The metal strip is bent in the shape of a ring which snugly encloses the switching contact and is constituted by a circular series of pairs of contact lips.

    摘要： A gas-blast circuit breaker comprising, within a switching chamber permanently filled with extinguishing gas under overpressure, a first and a second switching contact, the switching-off action of said switching contacts being effected by pistons which are spring biased against such action and are mounted within cylinders associated with said switching contacts, respectively, at least one of said cylinders being permanently in open communication with said switching chamber, a locking member being provided which is adapted to be released by a switching-off command and which is holding the switching contacts in their respective rest positions corresponding to the closed condition of the circuit breaker.

    摘要： A high voltage system includes at least two horizontal parallel bus bar systems enclosed in metal tubes and switching units connected thereto. The switching units each contain at least a circuit breaker and two bus bar isolating switches connected in series therewith and each isolating switch is connected to a bar of the bus bar system. The circuit breaker and the isolating switches are accommodated in a common metal casing which is joined to the metal tubes enclosing the bus bars through the medium of tubular extensions or collars which are joined to tubular parts extending perpendicularly upwardly from the metal tubes, the fixed contact of each isolating switch being permanently connected to the relevant bus bar and being contained in a respective one of the tubular parts.
