The invention discloses a cooling device for a frequency converter of a nuclear power plant, which comprises a cooling water tank, a working module and a conveying module, and is characterized in that an isolation device is arranged outside the cooling water tank; the working module is arranged in the frequency conversion cabinet and is used for cooling equipment in the frequency conversion cabinet; the conveying module is arranged in the cooling cabinet, the cooling cabinet is located on one side below the cooling water tank, the conveying module communicates with the cooling water tank and the working module, and the conveying module is used for conveying the cooling liquid in the cooling water tank to the working module. Therefore, while the equipment is subjected to water cooling, short circuit caused by leakage of the cooling water tank or the pipeline is avoided, the electrical equipment is prevented from being damaged, and normal operation of the main helium fan is ensured. 本发明公开了一种核电厂变频器的冷却装置，包括冷却水箱、工
