Embodiment Construction

[0050] First refer to figure 1 Describe the basic structure of a switchgear. The basic structure of the switchgear is also suitable for use in figure 2 The implementation variant shown in .

[0051] exist figure 1 and figure 2 The switching device shown in has a first arcing contact piece 1 and a second arcing contact piece 2 . The first arcing contact piece 1 and the second arcing contact piece 2 are arranged opposite one another, aligned coaxially to the axis 3 . Axis 3 is the longitudinal axis of the switching device, with which the switching device is aligned substantially coaxially. The two arc contacts 1 , 2 are arranged at a distance from one another and are relatively movable along an axis 3 . The first rated current contact piece 4 is aligned coaxially to the first arcing contact piece 1 . The second rated current contact piece 5 is aligned coaxially to the second arc contact piece 2 . The two rated current contacts 4 , 5 are of tubular design. A disconnect...

Abstract

A switching device with a disconnecting compartment (6) having an insulating material nozzle (7). The insulating material nozzle (7) has a nozzle channel (8) opening into the gas volume (10). A deflection element (14a, 14b) is arranged inside the gas volume (10), which is mounted within the deflection channel (15a, 15b).

Description

technical field [0001] The invention relates to a switching device with a disconnection compartment which is at least partially surrounded by an insulating material nozzle, the nozzle channel of which opens into a gas volume in which a deflection element is arranged. Background technique [0002] Such a switching device is known, for example, from the abstract of Japanese patent document JP02-086023. In this case, the disconnection space is surrounded by the insulating material nozzle. The nozzle channel of the insulating material nozzle opens into the gas volume. During the switching process, the expanding quenching gas is directed through the nozzle channel into the gas volume. A deflection element is also provided in the gas volume, which causes a certain flushing of the gas volume with the quenching gas. [0003] A valve opening is provided at the end inside the gas volume. Such valve openings have a higher failure rate due to the movable elements than non-movable co...
