RUPTURE DISK FOR THE TRANSFORMER

摘要

PURPOSE: A rupture disk for a transformer is provided to prevent the occurrence of additional accidents by effectively discharging pressures generated inside the transformer. CONSTITUTION: A cylindrical hollow enclosure(12) is expanded to the vertical upper side of an opening part which is formed at the upper cover(110) of a transformer. A rupture disk crosses the inside of the enclosure. A cutting part(122) is spaced apart from the upper side of the rupture disk. A protective cover(14') covers the upper side of the enclosure. A plurality of spacers(124) is radially protruded from the outer circumference of the enclosure. Protrusions(146') are protruded from the edge part to the inner part of the protective cover. The protrusions are arranged in spaces formed by the spacers.
