Power Transmission Transformers

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

1. The fire separation distance between oil-immersed transformers with an oil content of more than 2500kg and oil-filled electrical equipment with an oil content of 600kg-2500kg should not be less than 5m.

2. When the fire separation distance between two adjacent oil-immersed transformers does not meet the requirements, a fire partition wall should be installed or a fireproof water curtain 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.

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, a firewall should be used for the outer wall. The distance between this wall and the outer edge of the transformer should 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, no doors, windows or holes should be opened below the horizontal line of the total thickness of the transformer plus 3m and within the range of the outer edges on both sides plus 3m; no doors, windows or holes should be opened outside this range. The fire resistance rating of doors and fixed windows on fireproof walls shall not be less than 0.9h.

5. When the oil volume of an oil-immersed transformer and other oil-filled electrical equipment exceeds 1000Kg per unit, an oil storage pit and a public oil collection pool should be set up, and transformer pebbles should be placed for fire prevention and oil unloading.

6． Oil-immersed transformers should be equipped with fixed water spray and other fire extinguishing systems in accordance with current relevant regulations. Oil-immersed factory transformers should be installed in a separate room. The door of the room should be a Class B fire door that opens outwards and leads directly to the outside of the house or corridor, and should not open to other rooms.

The operating voltage of the power transformer should generally not be higher than 105% of the operating tap voltage, and shall not exceed the maximum operating voltage of the system. For special use cases, operation at no more than 110% of the rated voltage is allowed.

The top oil temperature of oil-immersed transformers should not exceed operating procedures or manufacturer's specifications. For forced oil circulation water-cooled transformers, the top oil temperature should generally not exceed 700°C.

Transformers with strong oil circulation cooling should be able to control the cooling operation according to temperature and/or load.

When a transformer is put into operation, the indications of the instrument should be constantly monitored and the operation status of the transformer should be grasped in a timely manner. If defects or abnormalities are found, measures should be taken to eliminate them promptly. If it cannot be eliminated at that time, surveillance must be strengthened. Prevent the expansion of accidents. and determine countermeasures as soon as possible.
