LOW -VOLTAGE CIRCUIT BRAEAKER WITH AN ARC-EXTINGUISHER CHAMBER AND A SWITCHING GAS DAMPER
A low voltage circuit breaker ( 1 ) has an arc extinguishing chamber ( 2 ) and a switching gas damper ( 4 ) which consists of two partial bodies ( 6, 7 ) that are displaceable in relation to each other. One ( 6 ) of the partial bodies ( 6, 7 ) is fixed to the circuit-breaker ( 1 ), while the other (...

| Zusammenfassung: | A low voltage circuit breaker (
1
) has an arc extinguishing chamber (
2
) and a switching gas damper (
4
) which consists of two partial bodies (
6, 7
) that are displaceable in relation to each other. One (
6
) of the partial bodies (
6, 7
) is fixed to the circuit-breaker (
1
), while the other (
7
) is pre-stressed against the first partial body (
6
) with an elastic restoring force (spring
12
). The switching gases that are discharged from the arc-extinguishing chamber (
2
) are contained inside (
8
) the switching gas damper (
4
) until the relative displacement of the partial bodies (
6, 7
) forms a flow outlet through which the switching gases can escape. |
