摘要： A self-extinguishing expansion switch or circuit breaker, including an extinguishing chamber and an expansion chamber connected by a duct. The extinguishing chamber is positioned above the expansion chamber. An axially movable tube supports a movable arcing contact which is cooperable with a stationary arcing contact. The axially movable tube separates axially from a conducting tube supported by an operating rod such that the circuit breaker is in an isolated position beyond an open position.

摘要： The device measures the current intensity in a conductor by FARADAY effect in a monomode optic fiber. It comprises a separator-polarizer formed for example by two coplanar half-disks of polarizing foil, whose polarization directions form a required angle, 90.degree. or 45.degree.. Photodiodes formed by a two-quadrant photodetector in the shape of a disk of the same diameter as that formed by the separator-polarizer, are located behind from the separator-polarizer. The photodiodes are connected to an electronic unit.
