The invention discloses a board card pluggable flexible DC transmission power module. According to the board card pluggable flexible DC transmission power module, primary elements and a secondary board card are arranged in separated regions, and the characteristic of pluggable board card maintenance is further realized. The board card pluggable flexible DC transmission power module comprises an energy storage capacitor, an IGBT unit, a Busbar, a control box assembly, a thyristor, a water cooling heat radiator, a resistor, a vacuum contactor, a foundation and a bottom board, wherein the energy storage capacitor is mounted at one end of the bottom board, the foundation and the vacuum contact are both mounted at the other end of the bottom board, the heat radiator is mounted above the foundation, a power unit is separated into a primary side and a secondary side through the heat radiator, the IGBT unit, the Busbar, the resistor and the thyristor are mounted in the primary side, a control box assembly is mounted at the secondary side, the control box assembly can be integrally mounted and dismounted, and the board card in the control box can be independently plugged and unplugged. The board card pluggable flexible DC transmission power module has properties of high voltage resistance, heavy current resistance, strong electromagnetic interference resistance and excellent heat radiation performance required by electric power equipment and further has advantages of electrical wiring maneuverability and maintainability.
