Heating and dehumidifying device and method for wind power converter

The invention discloses a heating and dehumidifying device and method for a wind power converter, and relates to the field of wind power devices. The device comprises a heating and dehumidifying circuit, a judgment control center and a temperature and humidity sensor. The method implemented by applying the device mainly comprises the steps that S1 temperature and humidity are detected, and data are transferred to a judgment control center; S2 the operating condition is judged, if the temperature is above 0 DEG C and condensation does not exist, step S3 is carried out; if the temperature is below 0 DEG C and condensation exists, step S4 is carried out; S3 a stop signal is output, and temperature and humidity information is collected in real time, and uploaded to the judgment control center;and S4 a work signal is output; heating and dehumidifying are carried out; temperature and humidity information is collected in real time and uploaded to the judgment control center. According to theinvention, the wind power
