Converter valve sub-module temperature detection method, device, equipment and medium

The invention discloses a converter valve submodule temperature detection method and device, equipment and a medium. The method comprises the steps of obtaining a preset number of temperature data of a target converter valve sub-module according to a first radio frequency signal as a first temperature data set, obtaining a preset number of temperature data of the target converter valve sub-module according to a second radio frequency signal as a second temperature data set, and determining a first average temperature according to the first temperature data set, and determining a second average temperature according to the second temperature data set, determining a difference value between the first average temperature and the second average temperature as a first difference value, judging whether the first difference value is smaller than or equal to a preset difference value, and if the first difference value is smaller than or equal to the preset difference value, taking the second average temperature as th
