Advanced Vacuum Drying TechnologyUtilizing a combined Roots Vacuum Pump and Rotary Vane Pump, our furnace reaches an ultimate vacuum of 10 Pa. This advanced technology enables optimal moisture extraction from power transformer cores, ensuring higher insulation reliability and extended equipment lifespan in a precisely controlled environment.
Intelligent, User-Centric ControlThe integrated touchscreen HMI and automatic digital controller offer seamless operation, including auto/manual modes, fine temperature accuracy (2C), and easy monitoring. Safety systems such as over-temperature protection, emergency stop features, and door interlocking enhance user confidence during operation.
Robust Construction and Efficient LoadingCrafted from powder-coated mild steel, insulated with high-density ceramic wool, the furnace boasts a double leaf hinged door and hydraulic lifting platform for convenient load handling. Its large internal space (5000 x 2500 x 3000 mm) accommodates transformer cores up to 3900 x 2900 x 2700 mm, supporting versatile industrial installations.
FAQs of Power Transformer Vacuum Drying Furance Manufacturing:
Q: How does the Power Transformer Vacuum Drying Furnace operate to remove moisture from transformer cores?
A: This furnace uses a combination of Roots Vacuum and Rotary Vane pumps to achieve a vacuum level of 10 Pa, while circulating hot air (up to 150C). The vacuum environment enables effective dehydration by lowering the boiling point of moisture, ensuring quick and thorough drying for transformer cores up to 60 tons.
Q: What transformer core sizes and weights can this furnace accommodate?
A: The PT-VDF-6000 model is designed for transformer cores with maximum dimensions of 3900 mm x 2900 mm x 2700 mm, and up to 60 tons. Its spacious internal volume and robust hydraulic lifting platform facilitate easy handling of large and heavy cores.
Q: When should a transformer manufacturer use this vacuum drying furnace in their production process?
A: This furnace is used after the transformer core winding and assembly processes but before final assembly and oil filling. It removes any residual moisture, which is essential for maintaining electrical insulation and transformer reliability.
Q: Where should the Power Transformer Vacuum Drying Furnace be installed?
A: The furnace is intended for floor-mounted installation in an indoor industrial setting. Its durable construction and insulation make it suitable for transformer manufacturing plants and large-scale service facilities.
Q: What safety features are included to protect operators during usage?
A: Key safety features include over-temperature protection, an emergency stop button, door interlocking systems to prevent accidental opening under operation, and thermal insulation to safeguard against excessive heat.
Q: What are the main benefits of using this vacuum drying furnace for transformer manufacturing?
A: The main benefits include precise, rapid drying of large transformer cores, improved insulation performance, reduced risk of moisture-induced failures, energy efficiency, and enhanced operator safety due to thoughtful design and advanced controls.
Q: How is the drying process controlled and monitored within the furnace?
A: The drying process is managed using a touchscreen HMI and digital controller, allowing both automatic and manual modes. Operators can monitor parameters such as temperature, vacuum level, and drying progress in real time, with 2C temperature accuracy and comprehensive safety alarms.
