    Abstract: The transformation plan was raised for new type main transformer cooler system based on the control of programmable logic controller (PLC) and solid state relay, and analysis was made to the AC power circuit, control circuit and electrical schematic diagram of secondary circuit after transformation. The results show that via transformation of original main transformer cooler, the insufficient part of design and design defect are eliminated, which realizes multi-operation control modes and assures the safe operation of main transformer cooler.
              Key words: transformer cooler; programmable logic controller; system improvement
