The utility model discloses a multi-transformation ratio open-close type mutual inductor. Mainly solves the problems that the existing open-close type mutual inductor is a single-transformation-ratio mutual inductor, cannot meet the requirements of various lines and is not flexible to use. The transformer is characterized in that the shell is provided with a coil common terminal (4) and at least two terminals (5) which are wound and pulled out through different binding numbers and are connected, the terminals comprise a first terminal (51) and a second terminal (52), and the transformation ratio between the coil common terminal and the first terminal (51) is different from the transformation ratio between the coil common terminal and the second terminal. According to the multi-transformation-ratio open-close type mutual inductor, different line requirements can be met through one mutual inductor, transformation ratio conversion can be achieved without replacing the mutual inductor when line loads are increase
