Self-expansion electrical circuit breaker with variable extinguishing chamber volume |
摘要 |
A self-expansion electrical circuit breaker includes an arc extinguishing chamber of variable volume by repulsion of a piston by the pressure of the gas in the extinguishing chamber. A semi-stationary contact is securedly united to the piston so as to increase the separation distance of the contacts at the same time as the volume of the extinguishing chamber increases.
