RESEARCH OF DE-ICING METHOD AND DEVICE BASED ON 12-PULSE RECTIFICATION FOR 500KV TRANSMISSION LINES
Because of the multi-splitting of the 500kV lines, the large de-icing current is required. This paper presents the DC de-icing method based on 12-pulse rectification by the regulation of the multilevel voltage and the parallel or series DC out voltage.. Through the analysis of the mathematical theory and the system simulation, this method can satisfy the ice-melting demands of different lengths of 500kV line. The device has been used to conduct the field test on the 500kV transmission lines. The experiment results show that the temperature-rise is obvious. It can solve the problem of ice-melting of 500kV transmission lines.
