To address the problems of high energy consumption, long drying cycles, and oxidation of iron cores associated with traditional drying technologies for distribution transformer bodies, this study proposes a vacuum-radiation-based drying technology. In a vacuum environment, this technology uses 0. 3-10THz electromagnetic radiation to excite hydrogen-bond resonance in water molecules, thereby achieving rapid vaporization. Combined with a nitrogen-assisted system, it enhances the drying effectiveness and suppresses oxidation and corrosion of the transformer core. A PID-based temperature regulation system is adopted to achieve high-precision temperature control, while the size, shape, and layout of the radiation plates are optimized to ensure uniform. electromagnetic coverage inside the vacuum drying chamber. Practical verification shows that this technology reduces energy consumption by over 60% compared with traditional methods. The drying time for a 10kV/630kVA distribution transformer body is 6-8 hours, and 12-15 hours for a 35kV / 6300kVA transformer body. This technology demonstrates significant advantages in energy efficiency, drying uniformity, and operational reliability, providing a new technical solution for drying distribution transformer bodies.
