DEVICE FOR PREVENTING THE EXPLODING OF AN ELECTRIC TRANSFORMER FITTED WITH A LIQUID INDICATOR

摘要

Device for preventing the explosion of an electric transformer (1) provided with a tank containing cooling liquid (7). The device comprises a rupture element (15) provided with zones that tear and with zones that crumple upon rupture. The rupture element (15) is able to rupture when the pressure inside the tank exceeds a predetermined upper threshold. A retaining bracket for the rupture element is positioned on the opposite side of the rupture element to the tank. A liquid detector (24) is positioned on the side of the rupture element (15) opposite to the tank.
