Abstract
The high-voltage switching device used in one installation position and has metallic encapsulation (10) a switching gap (4) and a particle trap (1) for holding foreign body particles (2), and is characterized in that in the one installation position, the particle trap (1) is arranged vertically underneath the switching gap (4), in the one installation position, an isolator part (8) is provided, which has a surface (8a) aligned essentially horizontally and faces the interior of the high-voltage switching device, with a metallic wall (9), which is higher than the particle trap (1; 1′), being arranged between the isolator part (8) and the particle trap (1; 1′). The particle trap (1) has a viewing window (3). If the high-voltage switching device is a disconnector, this viewing window (3) may be identical to the viewing window (3) for visual access to the visible disconnecting gap (4) of the disconnector. The high-voltage switching device is used particularly advantageously in a second installation position and has a second particle trap, with the second particle trap arranged vertically underneath the switching gap (4) in the second installation position. This results in the high-volta…
