Embodiment Construction

[0021] Figure 1 to Figure 4 A switching device according to an embodiment of the invention is shown. The switching device according to the invention is part of an electrical switching device with double opening contacts, known per se and not shown here. Briefly, the switching device according to the invention comprises a switching element 1 which can be moved back and forth in a switching chamber 2 along a linear movement axis Z between a conducting position and an breaking position, the switching element 1 being in the conducting position The position establishes an electrical connection between two stationary contacts (not shown) of the switching device, the switching element 1 being at a distance from the stationary contacts in the open position.

[0022] figure 1 The switching device is shown comprising a bracket housing 3 . The carrier housing 3 , which can also be described as a switching bridge, is arranged in the switching device such that it can be moved along the...

Abstract

The invention relates to a switching device comprising: a switching chamber (2); a plate-shaped switching element (1) capable of moving in the switching chamber (2) along a linear movement axis (Z) between said switching element ( 1) Move between the conduction position where the static contacts are connected to each other and the disconnection position where the switching element (1) is at a certain distance from the static contacts; for inside the switch chamber (2) drive means (22) for linearly moving said switching element (1); spring means (8) for prestressing said switching element (1) in the direction of said movement axis (Z), characterized in that the guide A device (10) is provided and configured such that said switching element (1) in said switching chamber (2) is guided in a linearly displaceable manner along said axis of motion (Z), and said switching element ( 1) is held such that the main axis (N) of the switching element (1) is oriented at least substantially parallel to the axis of motion (Z), the main axis (N) of the switching element (1) relative to the switching element ( The two main directions of extension (X, Y) of 1) extend perpendicularly.

Description

technical field [0001] The invention relates to a switchgear, comprising: a switch chamber; a plate-shaped switch element, the plate-shaped switch element can move along a linear axis in the switch chamber at a conduction position where the switch element connects static contacts to each other and the switch element and the static contact movement between off-positions at a distance; drive means for linearly moving the switching element inside the switching chamber, and spring means for prestressing the switching element in the direction of the axis of motion. Background technique [0002] An electrical switching device is a component in an electric circuit that makes an electrical connection ("on" switch state or "conducting" state) or breaks this connection ("off" switch state or "off" state) between stationary contacts. on" state). If the electrical connection is to be broken, current flows through the switching element through the contacts connected to each other until ...
