Oil-immersed transformers should pay special attention to their fire safety measures. The fireproof distance between oil-immersed transformers with oil capacity above 2500kg and oil-filled electrical equipment with oil capacity between 600kg-2500kg should not be less than 5 m. When the fireproof distance between two adjacent oil-immersed transformers does not satisfy the requirements, a fireproof partition wall or a fireproof water screen on top of the fireproof partition wall should be set up. Single-phase oil-immersed transformer can only set up fireproof partition wall or fireproof water screen between
The outer wall of the plant from the outer edge of the oil-immersed transformer 5m or less, in the total thickness of the transformer plus 3m below the horizontal line and on both sides of the outer edge of each plus 3m, should not be opened doors, windows and holes; outside its scope of the firewall on the door and the fixed window, the fire-resistant limit of the fire-resistant limit should not be less than 0.9h. Oil-immersed transformers and other oil-filled electrical equipment, a single oil volume of more than 1,000Kg, the installation of the oil storage pits and Public oil collection tank, and place the transformer pebbles to be used for fire prevention and oil unloading. Oil-immersed transformers require strict implementation of existing regulations and the installation of fixed water spray and other fire extinguishing systems. Oil-immersed transformers should be set up in a separate room, the door of which should be a Class B fire door that opens to the outside and leads to the outside of the house or corridor, and should not open to other rooms.
Fire safety is very important, pay attention to the use of 25 kva single phase transformer, 20 kva single phase transformer, 240v single phase transformer and other transformers to protect you and me.
