Necessary point uses oil-immersed transformers

As technology advances, more and more inseparable from the electrical current life, so a lot of related equipment and electricity, today to say something about some of the knowledge of the transformer:
Oil-immersed transformers and other products different is that oil-immersed transformer which is equipped with transformer oil, after reaching the ignition point of spontaneous combustion and fire may occur, resulting in accidental injury, the use of oil-filled transformers need to note the following:
First, oil-immersed transformers shall be related to the current specification, provided a fixed water spraying fire extinguishing system. Oil-immersed transformer plant should be set up in a separate room, the door of the room should be B fire doors open outwards, and direct access to the outdoors or corridors, not open to other rooms. Second, power and distribution transformer manufacturer and other oil-filled electrical equipment during a single fuel than 1000Kg, set oil storage and a common set sump pit and pebbles to spare to put a transformer fire and unloading.
Third, when the spacing between adjacent fire between the two oil-immersed transformer does not meet the requirements should be set at the top of the fire wall or fire wall add fire water curtain. You can only set fire wall or fire water curtain between the single-phase oil-immersed transformers.
Fourth, the amount of oil in more than 2500kg of oil-immersed transformers and oil between the 600kg-2500kg of oil-filled electrical equipment, the fire spacing should be less than 5m.
Fifth, when the oil-immersed transformer factory facades from the outer edge of less than 5m, the total thickness of the transformer plus 3m below the horizon and scope within 3m of the outer edge of each plus sides, should open doors and windows and holes; it outside its scope Doors and fixed windows firewall, its fire resistance of not less than 0.9h.
