FIELD: electricity.
SUBSTANCE: device for electric transformer protection against blowout of tank and fire contains tank with liquid dielectric. Expansion reservoir is connected with above mentioned tank by means of pipeline. Additional reservoir is connected with tank by means of fitting pipe of small hydraulic friction and is filled with inert gas. In additional reservoir separator of liquid and gas mediums and outlet fitting with possibility to communicate with atmosphere are installed. Flame arrester, rupture disc and non-return valve are installed in outlet fitting. Fitting of small hydraulic friction is included into circular cavity. Circular cavity is performed with diameter incline and maximum height equal to pipeline diameter. The pipeline providing connection of expander reservoir and tank is attached to circular cavity.
EFFECT: providing of compactness and pressure compensation.
