    Abstract: Introduction was made to the vacuum drying and oiling tank system. This paper adopted voltage transformation vacuum drying and vacuum oiling controlled by a programmable logic controller. The temperature sensor and liquid level sensor measured the system’s real-time data, and then the system transmitted the disposed data to the database. The monitoring system realized the main process parameters automatic detection and data processing. The man-machine interface displayed the vacuum drying and vacuum oiling process flow diagram of voltage transformation method, with the functions of alarm protection and safety protection. The operating result shows that this system speeds up the
oil-immersed transformer drying and oiling productive process with good drying effect, excellent oiling process and low failure rate.
    Key words: voltage transformation vacuum drying; vacuum oiling; industrial computer; programmable logic controller
