FIELD: protective devices.
SUBSTANCE: invention relates to an automatic protection system comprising a SF6 tank having a wall and a SF6 heating system. SF6 heating system includes a heater located outside the tank and a radiator located on the wall inside the SF6 tank. Radiator is thermally connected to the heater through the wall. Heating system is designed to transfer heat from the heater to the radiator through the wall. Radiator is designed to radiate heat to SF6 gas in the tank. Automatic protection system contains a SF6 gas tank with a wall and a particle trap. Particle trap has a stringer extending radially inwardly from the wall, and a wing extending away from each side of the stringer. Each wing is separated from the wall and forms an area that does not have an electric field, at the bottom of the tank next to the stringer.
EFFECT: technical result is improved heating and particle trapping.
