Switching gas damper for low-voltage power circuit breakers |
摘要 |
A switching gas damper for low-voltage power circuit breakers, is arranged as an attachment above the arcing chambers for additional damping, deionization and cooling of the switching gases. The switching gas damper includes a cuboid enclosure with separate inlet openings to receive switching gas flows from each arcing chamber in the low-voltage power circuit breaker. Separate outlet channels are formed by channel walls and/or by deflection elements and are routed on both sides of the power circuit breaker. A variable arrangement of the deflection elements and outlet channels makes it possible to produce a number of mutually separate flow paths, with different desired damping and cooling characteristics, as a function of the gas amounts that occur and of the characteristics of the arcing chambers that are used.
