VORRICHTUNG ZUM VERHINDERN EINES ZUR EXPLOSION FUEHRENDEN DRUCKANSTIEGES IN FLUESSIGKEITSGEFUELLTEN BEHAELTERN MITTELS IN DER FLUESSIGKEIT EINGELAGERTER LEICHT ZERBRECHLICHER HOHLKOERPER

摘要

The device, e.g. a transformer (1), has a ceramic insulator (2). The device is filled with oil (7). To protect the oil-filled device reliably against bursting, glass spheres (6) filled with inert gas are provided, and are continuously distributed over essentially the whole oil-filled space. If the pressure rises, the glass spheres (6) are crushed, and the escaping inert gas acts as a fire extinguisher. <IMAGE>
