As an important large-scale electrical equipment, transformers should be properly protected for fire protection in daily use.

With the construction of large power grids, the safe operation of main transformers becomes more and more important. Transformer fire is a serious accident in a transformer accident, which poses a serious threat to the safe operation of the power grid and social and economic development. To reduce this threat, the current effective measures include improving the quality of products, improving the level of daily maintenance and the fire protection of transformers. Measures are also very important aspects.

1. The main transformer should be located in the center of the accident oil sump filled with pebbles. An accident drain valve should be provided at the bottom of the fuel tank;

2. When a fire occurs in the main transformer, the circuit breakers on the high and low voltage sides should be opened immediately. And pull the isolating switch to confirm that the transformer is not live before extinguishing the fire;

3. For indoor plant transformers and excitation transformers, sand boxes and fire extinguishers should be provided indoors. In the event of a fire in the transformer, the 6.3KV isolation switch on the indoor wall, such as a mine dry transformer, should be opened immediately. After confirming that the transformer is not live, use sand or a fire extinguisher to extinguish the fire.
