Abstract

The circuit breaker has switching elements (6) which are connected virtually rigidly to one another and are fitted at the outer end (13) of column insulators (1). The lower end (12) of each column insulator (1) is attached to a common foundation (4) by means of a spring device (3). Provided at a distance from the lower end (12) of each column insulator (1) is at least one further spring device (3') which allows the parts (1, 5) which are connected through it to be deflected with respect to one another at least in the plane in which the column insulators (1) are arranged. In consequence, the parts (5, 6) which are located above this spring device (3') can execute a movement which scarcely deviates from the horizontal when the column insulator (1) is swinging out, as a result of which high bending stresses on the head ends of the column insulator are prevented.
