Abstract: The freezing always exerts pernicious influence on metal gates. Taking the successful application of bubble anti-icing technology in the protection of spillway gate in dam section 28 of Taipingwan hydropower station as an example, this paper introduces the principle of freezing process, the principle of bubble anti-icing and the working principle of anti-icing system for hydropower projects. Based on the achievements so far, the construction of anti-icing facilities for Taipingwan hydropower station is planned in stages, and the application prospect of anti-icing technology with PLC automatic control technology is expounded.
