Oil-immersed transformers should pay special attention to their fire safety management measures. In oil-filled transformers and 2500 kg of oil above 600 kg of oil - oil-filled electrical equipment, with a fire separation of not less than 5 meters between 2500 kg. When the fire safety distance between two adjacent oil-immersed transformers does not meet the design requirements, a fire partition wall should be set up or a fireproof water duct should be added to the top of the fire partition wall. Only fireproof partition walls or fireproof water curtains can be installed between single-phase oil-immersed transformers. When the predetermined outer edge of the outside distance from the specification table workshop wall is smaller than the oil-filled transformer, the outer wall should be a firewall. The distance between the wall and the outer edge of the transformer should not be less than 0.8m. The external wall of the plant is within 5m from the outer edge of the oil-immersed transformer, the total thickness of the transformer plus horizontal line is less than 3μm 3m and the positive side of the outer edge is outside the range, and the fire resistance is not less than 0.9H.
