Abstract:
The invention relates to a medium voltage switchgear with an assembled pole part with integrated three-position switch, with pole part frames made of insulating material, between which a vacuum-interrupter is mounted, wherein the vacuum interrupter is provided with a fixed contact and a moving contact, so that one end of the frame is provided with a first support in order to fix the vacuum interrupter at the moving contact side, and fixation means for the fixed contact side at the other end of the frame. In order to to implement high technical functionality during reduction of the number of separate parts at same time, and additionally to implement a lower transmission resistance into the interconnection, the electrical connection between the movable part of the vacuum interrupter and the movable part of the two- or three-position switch is a mechanically flexible conductor element, and that the insulating pole part frames are provided with guiding means for the linear movable contact part of the two- or three- position switch, which are integrated into the pole part frames or the pole part frame arrangement.
Abstract:
The invention relates to an auxiliary switch (100) for an electrical application (200) such as a circuit breaker, with a first contact device (102) and a second contact device (122) which are adapted for a conducting current and attached to a bridge component (141) of the auxiliary switch (100) in parallel spaced apart from each other by a first distance (212) in a longitudinal direction (214) of a longitudinal side (147) of the bridge component (141). An actuating shaft (180) of the auxiliary switch (100) is adapted to rotate the bridge component (141) from a switch-off position (216) to a switch-on position (218, 220) in a switch-on direction (222, 224) around the shaft axis (183) of the shaft (180) by a switch-on rotary motion (226, 228) applied to the actuating shaft (180) such that the first contact device (102) and a second contact device (122) are adapted to slidingly contact conducting terminals (202, 204; 2021, 2041 ) of the electrical application (200) such that a current flow between the first contact device (102) and the second contact device (122) is provided.
Abstract:
The invention relates to an assembled pole part with two pole part frames (2, 3) made of insulating material, between which a vacuum interrupter (1) is mounted, and that the vacuum interrupter is applied with a fixed contact and a moving contact, so that at one end of the frame is applied with a support (21) in order to fix the vacuum interrupter at the moving contact side, and fixation means (10, 11, 12) for the fixed contact side at the other end of the frame. In order to apply common pole part frames for different vacuum interrupter sizes, the invention is, that at least two fixation means or fixation points (10, 11, 12) are arranged pairwise in parallel along different distances to each along the long axis of the frame, wherein the second support is the fixation means for the fixed contact side of the vacuum interrupter, in order be able to use one uniform constructed frame design for different vacuum interrupter lengths, in that way, that independent of the used vacuum interrupter length, the moving contact fixation support keeps at the same fixation position (21). Alternatively, support plates (20) of different thicknesses may be used.
