Pressure sensitive fault interrupter for a multi section AC capacitor

摘要

A multisection AC capacitor wherein each capacitor section has a pressure sensitive fault interrupter having a dome-shaped diaphragm mechanically and electrically secured to a contact bridge at the base of the capacitor roll, all capacitor sections within said case being electrically connected in parallel, such that a rising pressure within one section will cause the dome of the diaphragm of the faulty capacitor to be depressed, thereby breaking the electrical contact of one electrode, thus isolating the faulty capacitor from the power supply, while permitting the remaining capacitors in the multisection unit to function normally.
