Abstract
A disconnector for a GIS, including a pair of permanent contacts, one fixed and the other one movable along an axis, called the axis of the disconnector, a pair of arcing contacts, one fixed and the other one movable, an insulating part located inside the fixed arcing contact, means for pressing the insulating part against a front surface of the movable arcing contact, and an insulating ring located at the outlet of the fixed arcing contact.
Claims14
A disconnector for a Gas-Insulated Substation (GIS), comprising:
- a pair of permanent contacts, one fixed and the other one movable along an axis, called the axis of the disconnector;
- a pair of arcing contacts, one fixed and the other one movable;
- an insulating part located inside the fixed arcing contact, and a spring configured for pressing the insulating part against a front surface of the movable arcing contact;
- an insulating ring located at an outlet of the fixed arcing contact;
- and
- wherein, when the pair of arcing contacts separate, the pair of arcing contacts form, together with the insulating part and the insulating ring, a limited volume which contains a limited quantity of gas.
