Abstract:
A compressed gas interrupter having an enclosure which extends along a longitudinal axis, said interrupter comprising:a first contact assembly including a first permanent current contact and a first arc contact,a second contact assembly movable along said longitudinal axis relative to said first contact assembly and including a second permanent contact and a second arc contact, anda system for inserting a resistor when said interrupter closes and said second permanent contact and said second arc contact are respectively connected to said first permanent current contact and said first arc contact, said resistor being electrically connected in series between said first arc contact and said first permanent current contact,wherein said resistor insertion system comprises:two auxiliary contacts, a first of which is electrically connected to said first permanent current contact and a second of which is connected to said first arc contact, andwherein said two auxiliary contacts are movable relative to each other along said longitudinal axis to move toward each other when said interrupter closes to make a connection that short-circuits the resistor, said two auxiliary contacts which connect to each other and to move together, while connected, along said longitudinal axis to short-circuit said resistor prior to connection between said first permanent current contact and said second permanent current contact.
