Definitions
- the device for preventing explosion and fire in an electrical transformer provided with a tank filled with combustible coolant comprises a means for sensing the pressure in said tank and a means for partially draining the cooling contained in the tank.
- step 24 of injecting the inert gas 16 into the bottom of the tank 2 is systematically triggered after a given time delay, for example 20 seconds, to stir the fluid 7 in order to homogenize its temperature and also to smother any flames on the surface of the fluid 7 by expelling oxygen.
- the fluid 7, in general oil can only ignite at a temperature above the flash point, ie approximately 140 °.
- the surface of the fluid 7 reaches this value while the average temperature is at most 80 °.
