In the summer, hot weather, high temperature, and huge power consumption, which undoubtedly increased the oil-immersed transformers and other electrical equipment operating load. In order to ensure the summer electricity demand, we must ensure the safe operation of electrical equipment.
1. when the upper part of the transformer oil temperature reaches or exceeds 85 degrees Celsius, indicating that the transformer overload, should immediately reduce the load; If the temperature continues to rise, then the transformer may be internal failure, should be disconnected from the power supply.
2. install the relay protection device, and regular tests to ensure that the device is always sensitive.
3. strengthen the operation and management of the transformer and maintenance work, regularly do insulation testing.
4. the transformer design and installation should meet national standards.
5. add oil to the transformer, to ensure that the transformer oil quality.
6. oil-immersed transformer once fire, should use dry powder, carbon dioxide, 1211 fire extinguisher to fight fire.
Summer is the peak of the use of electrical equipment, in order to ensure the safety of electricity, we must do a good job of oil-immersed transformer fire prevention measures.
