PRESSURE-ACTUATED TRIPPING DEVICE FOR AN ELECTRICAL LINE PROTECTION APPARATUS

摘要

A pressure-actuated tripping device for an electrical line protection apparatus, of the circuit-breaker type, delimited by an enclosure and comprising inside the enclosure: - a gas inlet orifice opening into an upstream chamber; - a downstream chamber; - an actuator that can rotate against a return means between a rest position and a tripping position, the actuator being positioned between the upstream chamber and the downstream chamber and per se partially delimits the upstream chamber and the downstream chamber.
