The invention provides a traction converter. A converter module chamber and a reactor chamber in a cabinet body are located on the two sides of a cooling fan respectively, a high-voltage chamber is located on the side face of a cooling fan chamber and the side face of the reactor chamber, and the cabinet body is provided with an air inlet capable of being communicated with the converter module chamber and an air outlet capable of being communicated with the reactor chamber. A first ventilating duct and a second ventilating duct are arranged in the converter module chamber and the cooling fan chamber respectively, the temperature detection units are arranged in the converter module chamber and the reactor chamber respectively, and a transmission control unit transmits control signals to the fan control unit according to data fed back by the temperature detection units. And the fan control unit arranged in the high-voltage chamber controls the rotating speed of the cooling fan according to the control signal. T
