When selecting materials for K-factor transformers, it is generally forbidden to use low-temperature wires with low-density insulation such as silk-covered wires. Enameled copper wires or NOMAX copper wires above 180°C should be used to prevent as much as possible the internal collection of wires due to higher harmonics. The skin effect produces local high temperature damage to the insulating layer, which leads to breakdown of the insulating layer and damage to the transformer. The K-factor transformer is designed to reduce the thermal effect as much as possible, which can be achieved through the optimization of the coil design, the thickness-to-width ratio of the wire specification, and the number of parallel coils.
The design impedance of the K-factor transformer must select an appropriate impedance value, use low-loss ultra-thin silicon steel sheets, and the magnetic density should be lower than the design value of ordinary transformers, process production to enhance the structural strength, and reduce the thermal effect of the transformer zero sequence current at the neutral point. , High frequency heat addition effect and output side winding heat addition effect, etc.
