On June 17, technicians carried out comprehensive maintenance for two 110KV main transformers of Henan Wanda Aluminum Co., Ltd., which had been operating for more than ten years in a row, after power failure. I wish Henan Wanda Aluminum to march forward bravely and create another brilliant future!
The main transformer, which is the main step-down transformer used for power transmission and transformation in a unit or substation, is also the core part of the substation.
The main transformer is composed of the following aspects:
1. Body: The body directly converts electromagnetic energy, which is composed of iron core, coil, lead wire, insulation, etc.
2. Oil tank and cover: mainly composed of box, cover, bottom and accessories (such as 50 valve, oil sample valve, oil drain plug, grounding bolt, etc.).
3. Protection device: mainly composed of oil conservator, oil meter, oil purifier, Gas Relay, Moisture Absorber, thermometer, Pressure Relief Valve, etc.
4. Cooling mode: oil immersed self cooling, oil immersed air cooling, strong oil water cooling, strong oil air cooling.
5. Outgoing line bushing: It is composed of 25/300 cable bushing and BF-6/2000, BF-1/1000, BF - l/600 and BF-1/300 bushings.
6. 25 # or 45 # transformer oil is used as transformer oil to increase insulation strength and cool down the transformer;
