Oil-filled transformers should pay special attention to their fire safety measures

Oil-filled transformers are a new type of high-performance transformer with a more reasonable structure and better performance. The three-dimensional wound core of Oil-filled transformers has an equilateral triangular three-dimensional arrangement, and there is no air gap in the magnetic circuit. The winding is tighter, the length of the three magnetic circuits is the same, and all of them are the shortest. The cross-sectional area of the core column of the Oil-filled transformers is closer to a circle. Therefore, the performance of the Oil-filled transformers is further improved, the loss is reduced, and the noise is reduced. Item balance, reduce the third harmonic component, Oil-filled transformers are more suitable for urban and rural, industrial and mining enterprises power grid transformation. So what are the fire safety measures for Oil-filled transformers?

This is the content list:

• There must be a corresponding fire separation distance

• The distance between the outer wall of the factory building and the outer edge of the oil-immersed transformer should be appropriate

• Oil-immersed transformers should be by the current relevant regulations

There must be a corresponding fire separation distance

The fire separation distance between Oil-filled transformers with an oil volume of more than 2500kg and oil-filled electrical equipment with an oil volume of 600kg-2500kg shall not be less than 5m. When the fire separation distance between two adjacent Oil-filled transformers does not meet the requirements, a fire partition wall or a fire water curtain should be installed on the top of the fire partition wall. Between single-phase Oil-filled transformers, only fire partition walls or fire water curtains can be installed.

The distance between the outer wall of the factory building and the outer edge of the Oil-filled transformers should be appropriate

When the distance between the outer wall of the factory building and the outer edge of the outdoor Oil-filled transformers is less than that specified in the specification table, the outer wall shall adopt a firewall. The distance between the wall and the outer edge of the Oil-filled transformers shall not be less than 0.8m. When the outer wall of the factory building is within 5m from the outer edge of the Oil-filled transformers, no doors, windows, and holes shall be opened under the total thickness of the Oil-filled transformers plus the horizontal line of 3m and within the range of the outer edges of both sides plus 3m. The fire-resistance rating of doors and fixed windows on the firewall outside its scope shall not be less than 0.9h. When Oil-filled transformers and other oil-filled electrical equipment have a single oil volume of more than 1000Kg, oil storage pits and public oil collection basins should be set up, and Oil-filled transformers pebbles should be placed for fire prevention and oil unloading.

Oil-filled transformers should be under the current relevant specifications

The Oil-filled transformers are equipped with fixed water spray and other fire extinguishing systems. The Oil-filled transformers should be set in a separate room, and the door of the room should be a Class B fire door that opens outwards, and directly leads to the outside of the house or the corridor, and should not open to other rooms.
