Device for containment of gas leaks occurring at e.g. shear disk of gas insulation switchgear compartment, has enclosure including shear disk or metal membrane adapted to break under gas pressure lower than rupture element rupture pressure

摘要

The device (10) has a sealed enclosure (101) enclosing an entire exterior surface of a rupture element e.g. shear disk. A surface of the enclosure includes a sealing portion provided to be secured around a tubular base (14) of a compartment. The enclosure includes a shear disk or a metal membrane adapted to break under a gas pressure lower than a rupture pressure of the rupture element. The enclosure is made of two half-shells, which are assembled by bolting. A clamp allows applying of a sealed closing portion against the tubular base. The shear disk is made of aluminum. An independent claim is also included for a method for sealing a device for containment of gas leaks.
