Abstract:This paper presents a method for the non-loss of electric melting based on strong excitation mode, which is based on the technical defects such as poor effect, huge energy consumption and difficult non-loss operation. The method using the skin effect improve the efficiency of circuit conductor of heat, with the help of ice beneath conductive characteristics make ice under strong excitation power supply provide effective heat melting ice, finally achieved under the same heating power to reduce the line current. By setting up the filter at both ends of the melting ice line, the non-working frequency harmonic which is introduced by the excitation power is suppressed, which makes the operation of the melting ice in the non-losing power condition possible. The simulation analysis shows that the melting ice method can provide better heating efficiency and reasonable heat distribution.
