Embodiment Construction

[0072] figure 1 On the left is shown the equivalent circuit diagram of a three-position switch 5 with a main current path 10, a bypass current path 15, a first main current path fixed contact 50, a second main current path fixed contact 60 , the bypass current path fixed contact 70, the grounding fixed contact 80 and the arc extinguishing device 150 (here a vacuum switching tube).

[0073] exist figure 1On the right side of , a schematic diagram of the three-position switch 5 according to the invention is shown in the "on" position. The three-position switch 5 has a bypass current path formed by an arc extinguishing device 150, and has an arc extinguishing contact 160, that is, an arc extinguishing fixed contact 163, an arc extinguishing movable contact 165, an arc extinguishing movable contact 165 and a bypass current path The contact strip 170 between the fixed contacts 70 and the bypass current path to the fixed contacts 70 . Furthermore, the three-position switch 5 has ...

Abstract

The invention relates to a switch installation, particularly for medium and/or high voltages, comprising an optimised three-position switch, and to an optimised three-position switch, wherein the three-position switch (5) comprises a main current path (10) and an auxiliary current path (15) which runs parallel to said main current path (10).

Description

technical field [0001] The invention relates to a switchgear, in particular a switchgear for medium and / or high voltage, and an optimized three-position switch, the switchgear having an optimized three-position switch. Background technique [0002] The load-disconnecting switch must be able to conduct and disconnect the nominal current of the network, wherein in the "open" switching state a defined insulation distance must be maintained. The load disconnect switch must also be able to conduct rated current as well as short-term current, be able to make short-circuit currents and be able to extinguish switching arcs. The power of a load disconnect switch is primarily defined by the rated voltage, the rated current and the nominal current (to be switched). [0003] A classic three-position switch is known, for example, from DE 10 2005 060 633 A1 for use in the SF6 environment and has a fixed contact and a moving contact. [0004] However, if the installation space is to be r...
