FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, particularly to transformer tanks. Proposed system comprise bearing part arranged in transformer tank to support screening plate without direct jointing it to transformer tank. Multiple burst disks are arrange on tube running outwards from transformer tank to get destructed when transformer tank pressure reached preset level. Multiple safety tanks are arranged along vertical line nearby the transformer to communicate with tubes. Further, lower part of every safety tank accommodates oil metre, which outputs signal when insulating oil enters safety tank.
EFFECT: higher reliability, longer life.
