Pressure-Changeable Vacuum Drying & Oil Filling Machine for Oil-Immersed Transformer Active PartBuilt on transformer vacuum oil filling and vacuum drying principles, this dual-purpose equipment is dedicated to drying the active parts of oil-immersed transformers. During the drying process, the vacuum system continuously varies the pressure inside the drying tank, enabling uniform product heating and timely removal of evaporated moisture—preventing core rust, reducing deformation, and achieving more thorough drying. Thanks to its rational structure and advanced process, drying time is reduced by approximately 40% compared with conventional vacuum drying. The machine delivers reliable, high-efficiency, energy-saving performance for transformer manufacturers worldwide.

Description
1. Core Features & Advantages ① Pressure-Changeable Vacuum Drying Technology Continuously alternates tank pressure to create ideal conditions for moisture evaporation from the insulation of the active part. Ensures uniform heating, thorough deep-layer dehydration, and reliable drying results. ② Rust Prevention & Minimal Deformation Timely removal of evaporated water prevents iron core rust. Gradual step-by-step drying minimizes product deformation and ensures more complete drying of insulation materials. ③ ~40% Shorter Drying Time The rational equipment structure and optimized drying process reduce drying time by approximately 40% compared with conventional vacuum drying—highly efficient and energy-saving. ④ 304 Stainless Steel Oil Tank & Pipelines Oil tank and all oil pipelines are made of 304 stainless steel, eliminating impurities and contamination. Oil filling supports both automatic and manual modes for precise oil volume control. ⑤ Advanced Vacuum & Condenser System A newly designed condenser cools most moisture into condensed water for automatic discharge, effectively protecting vacuum pumps from water ingress. A high-temperature magnetic pump serves as the heat transfer pump, stabilizing the heating system and avoiding thermal oil leakage. ⑥ Automatic Pressure Exchange Control The body temperature is heated according to a time-based program, and automatic pressure exchange/transformation reduces vacuum tank pressure to a set value in cycles—creating optimal conditions for moisture evaporation throughout the drying process. ⑦ Anti-Rust & High Automation Scientific control of the variable-pressure drying process (combined with domestic and international technology) effectively solves core rust problems during drying. High automation level and product processing quality reach an advanced level; finished products meet superior industry standards. ⑧ Stable & Reliable Electric Control The electric control system and all component systems are stable and reliable, ensuring smooth, uninterrupted operation. 2.
