Transformer vacuum oil injection production line system for 300KV oil type transformers
Application scope:
The transformer vacuum oil injection production line system is mainly used for vacuum oil injection treatment of various distribution transformers, oil immersed transformers, amorphous transformers and other products (drying functions can be added according to the characteristics of the products). The system can be connected to the production line to improve production efficiency.
DESCRIPTION:
A transformer oil-filling plant with a vacuum process for 300kV oil type transformers is a facility designed to fill oil into high-voltage oil-filled transformers using a vacuum technique. This process ensures that the transformer is properly filled with oil and eliminates air and moisture, which can affect its performance and insulation properties. Here is a general overview of the steps involved in such a plant:
Preparation: The transformer is prepared by ensuring it is clean, dry, and all openings are accessible for the oil-filling process. The transformer should also be tested and inspected to ensure it meets the required standards.
Vacuum Chamber: The transformer is placed inside a vacuum chamber, which is a sealed enclosure capable of withstanding the required vacuum pressure. The chamber is equipped with ports for oil filling, vacuum creation, and monitoring instruments.
Vacuum Creation: A vacuum pump is used to create a vacuum inside the chamber. The vacuum removes air and moisture from the transformer and its components, ensuring a clean and dry environment for the oil filling process.
Oil Heating: The transformer oil is heated to a suitable temperature to improve its flow properties and reduce its viscosity. This heating process is typically done using an oil heater or a heat exchanger.
Oil Filling: Once the vacuum is established and the oil is heated, the oil is introduced into the transformer. This is usually done by connecting the oil supply to the transformer's oil inlet port. The oil is carefully poured or pumped into the transformer, filling it from the bottom up to minimize the introduction of air bubbles.
Vacuum Degassing: After the initial oil filling, the vacuum process continues to remove any remaining air and moisture from the oil and the transformer. This degassing process helps improve the oil's dielectric strength and ensures better insulation performance.
Monitoring and Control: Throughout the oil-filling process, various parameters such as vacuum level, oil temperature, and oil flow rate are monitored and controlled to ensure proper filling and degassing.
Completion and Testing: Once the oil filling and vacuum degassing process is complete, the transformer is sealed and prepared for further testing and commissioning. This may include additional tests such as insulation resistance, oil quality analysis, and electrical performance tests.
It's important to note that the specific equipment and processes in a transformer oil-filling plant may vary depending on the manufacturer and the requirements of the transformers being filled. Additionally, safety measures must be followed during the oil-filling process, as transformer oil can be flammable and hazardous.
