Arc-Extinguishing Devices That Are Switches
(AREA)
Abstract
Improvements in closed-circuit compressed gas switches, comprising a closed extinguishing chamber containing the compressed gas and a piston integral with the moving contact, causing the displacement of the piston during the opening movement of the contacts, generating an extinguishing blow of the rupture arc spacing, characterized by the fact that the piston is a differential piston held by locking in a position corresponding to the closure of the contacts, causing the unlocking, under the effect of the single pressure of the compressed gas, the displacement of the piston and the moving contact .
