摘要： An electrical transformer system includes an electrical transformer and a depressurization system in fluid communication with an outlet of the electrical transformer. The depressurization system may include a rupture disk housing assembly, a rupture disk cartridge, and a removable cover. The housing assembly may include a container having an opening and cavity to receive the cartridge and first and second flanges to connect to duct piping of the transformer. The removable cover may enclose the opening of the housing assembly. The cartridge may include a rupture disk secured between first and second disk support plates. The cartridge may be pre-assembled outside the housing assembly. The cartridge may be removed from and/or installed in the housing assembly through the opening. The rupture disk may be inspected, serviced, and/or replaced without disconnecting the housing assembly from the duct piping.

摘要： An electrical transformer system includes an electrical transformer and a depressurization system in fluid communication with an outlet of the electrical transformer. The depressurization system may include a rupture disk having a downwardly facing domed portion extending toward the outlet of the electrical transformer. The domed portion has an apex and a base with a retention portion surrounding the domed portion adjacent the base. A score line network extends circumferentially around the domed portion adjacent the base and spaced apart from the apex. The score line network includes a plurality of serrated score line segments and a plurality of hinge score line extending from the score line segments towards the apex of dome portion. The rupture disk may be interested into a housing assembly with a removable cover.
