Oil immersed transformer is an important power equipment, which is one of the main equipment of power plant and substation. In daily use, we should protect oil immersed transformer, and the fire protection of oil immersed transformer is very important. Because there is transformer oil in oil immersed transformer, when the insulating oil reaches the ignition point, it will spontaneously ignite. Therefore, the fire prevention of oil immersed transformer is very important. What are the fire prevention measures for oil immersed transformer? The following oil immersed transformer manufacturers give you a detailed introduction:
1. The fireproof distance between oil immersed transformer with oil content of more than 2500kg and oil filled electrical equipment with oil content of 600kg-2500kg shall not be less than 5m.
2. When the fire prevention distance between two adjacent oil immersed transformers does not meet the requirements, fire partition wall or fire water curtain shall be set at the top of the fire partition wall. The single-phase oil immersed transformer can only be provided with fire partition wall or fire water curtain.
3. When the distance between the outer wall of the factory building and the outer edge of the outdoor oil immersed transformer is less than that specified in the specification table, the outer wall shall adopt firewall. The distance between the wall and the outer edge of the transformer shall not be less than 0.8m.
4. When the outer wall of the factory building is within 5m from the outer edge of the oil immersed transformer, doors and windows and holes shall not be opened below the horizontal line of the total thickness of the transformer plus 3M and within the range of the outer edges of both sides plus 3M; the fire resistance limit of the doors and fixed windows on the firewall outside the scope shall not be less than 0.9h.
5. When the single oil volume of oil immersed transformer and other oil filled electrical equipment is more than 1000kg, oil storage pit and common oil sump shall be set, and pebbles of transformer shall be placed for fire prevention and oil unloading.
6. according to the existing regulations, set up fixed water spray and other fire extinguishing systems. The oil immersed auxiliary transformer shall be set in a separate room, and the door of the room shall be a class B fire door opening outward, which shall be directly connected to the outside or corridor, and shall not be opened to other rooms.
