使用气体的两相态来改进截止特性的自鼓风断路器
摘要：
本发明涉及一种用于中压或高压断路器的电流中断室(1)，该电流中断室(1)沿纵轴(XX')延伸并且包括：一对电弧触头(4，5)，该电弧触头中的至少一个电弧触头(5)可沿主轴(XX')运动；灭弧喷嘴(6)；鼓风室(7)，具有固定的并且在喷嘴内向外打开的容积V2；压缩室(8)，大体上设置在鼓风室的后面，以及用于将所述压缩室(8)的内容积与鼓风室(7)的内容积连通的装置(73，81)；大体上放置在压缩室(8)的后面以将液体传送到压缩室(8)或直接传送到鼓风室(7)中的装置(14，15，50)。
摘要（英）：

The invention concerns a current interrupter chamber (1) for a medium or high voltage circuit breaker extending along a longitudinal axis (XX') and comprising: a pair of arcing contacts (4, 5), at least one of which (5) is movable along the longitudinal axis (XX' ), an arc blowing nozzle (6), a blowing chamber (7) of which the volume V2 is fixed and that opens inside the blowing nozzle, a compression chamber (8), arranged substantially behind the blowing chamber, and means (73, 81) for making the inner volume of said compression chamber (8) and that of the blowing chamber (7) communicate, means (14, 15, 50), disposed substantially behind the compression chamber (8), for supplying a liquid, either in the compression chamber (8), or directly in the blowing chamber (7).
