About Vacuum Drying And Oil Filling Machine Plant For Transformer Production

VACUUM OIL FILLING EQUIPMENT

Description : This equipment is used to fill the transformer oil in vacuum condition (drying function can be added according to client's requirement). It is widely used for amorphous transformers, HV oil immersed transformers, HV bushings and capacitors, etc. The plant can automatically running and quantitative oil filling.

Equipment Features:

Perfect vacuum condition and precision quantitative filling to ensure high quality
Maximum adopts three-stage vacuum pump system, limit vacuum up to 1pa(unload), leakage rate <= 0.4mbar/s
Oil separator installed between vacuum tank and pump system can condensate and recovery some oil, so can reduce the damage and pollution to the pump system
Rectangle type tank adopts frame type flange to ensure long working life
Vacuum tank which has heating function is heated by electric through conductive oil. Tank door is heated by electric heating plate. Temperature raising is uniform and reliable, no local over heating
Heat exchanger is equipped if the vacuum tank has heating function, so the vacuum tank temperature can be reduced below 70C to reduce moisture regain during discharging
All oil filling pipelines and accessories are stainless steel. Flow meter equipped on main pipeline and each filling pipeline, the oil filling is adjustable and automatic control
PLC system and touch screen operating, fully automatic control on the whole process. All the parameters can be indicated, record and printed, impeccable alarm system.

Advanced Vacuum Technology for Optimal Drying

Our plant delivers exceptional vacuum drying capabilities, achieving vacuum degrees as low as 133 Pa. This ensures that the transformer core and coil are thoroughly dried, minimizing moisture and optimizing overall transformer performance. The adjustable forced air circulation, combined with the efficient two-stage rotary vane vacuum pump, enables consistent and uniform results throughout the internal chamber.

Efficient Oil Filling and Control System

With an impressive oil filling speed of up to 900 liters per hour, the VDOF-120 streamlines the oil impregnation process, reducing downtime and manpower requirements. The microprocessor-based automatic PLC control system allows precise management of temperature, humidity, and filling operations, ensuring process accuracy with a tolerance of 1C for temperature control.

User-Friendly Operation and Safety First

Equipped with a touchscreen HMI operator panel, the plant offers intuitive operation and monitoring. Essential safety features include automatic overheat protection and an emergency stop feature, providing peace of mind for users. The tempered glass observation window and integrated humidity sensor allow for real-time process observation and control, maximizing efficiency and safety.

FAQs of Vacuum Drying And Oil Filling Machine Plant For Transformer Production:

Q: How does the vacuum drying process work in this machine?

A: The VDOF-120 uses a two-stage rotary vane vacuum pump to achieve a vacuum degree of 133 Pa. This low pressure environment effectively removes moisture from the transformer core and coil, ensuring thorough drying before oil filling. Forced air circulation and precise temperature control enable uniform drying throughout the process.

Q: What is the procedure for oil filling using this plant?

A: Once the transformer is dried, the integrated system automatically fills oil at up to 900 L/hr, controlled by the PLC system. The process involves pumping oil from the 2000-liter tank through hydraulic piping into the transformer chamber, with temperature and humidity precisely managed for optimal impregnation.

Q: When should I use vacuum drying and oil filling for transformer production?

A: Vacuum drying and oil filling are critical steps after the winding and assembly of transformer cores and coils. These processes should be used prior to final assembly and enclosure sealing to prevent moisture retention, which could compromise dielectric strength and equipment longevity.

Q: Where can this machine be installed, and is on-site support available?

A: The VDOF-120 is designed for on-site installation at transformer manufacturing plants, service centers, or repair workshops. Wheel-mounted construction allows for easy mobility. On-site installation and technical support services are available to ensure seamless setup and operation.

Q: What are the benefits of using this vacuum drying and oil filling plant?

A: Key advantages include reduced drying and filling times, enhanced process control via automatic PLC and integrated sensors, higher transformer reliability, and improved insulation properties. Safety is also prioritized, with features like emergency stop and overheat protection.

Q: How is operator safety ensured during plant operation?

A: Operator safety is maintained through automatic overheat protection, an emergency stop button, tempered glass observation windows for monitoring, and an intuitive touchscreen HMI. All major components are housed within a robust, powder-coated stainless steel frame.
