Parallel Resonant Intermediate-Frequency Power Cabinet

The 12- or 24-pulse medium-frequency power supplies manufactured by Kangda Electric Furnace feature transformers with either dual-winding or quad-winding configurations, providing one star-connected output and one delta-connected output. The phase difference between each phase of the power supply is either 60° or 30°. During operation, the odd-order harmonics generated by the equipment can mutually cancel each other out, effectively ensuring electrical safety and meeting the national technical standards for harmonics. This multi-path power supply technology enhances power supply capacity and delivers significant energy-saving benefits, making it the preferred solution for manufacturing large-tonnage equipment. The system is equipped with comprehensive protection functions against overcurrent, overvoltage, water shortage, water temperature anomalies, and phase loss, thereby guaranteeing stable equipment operation.

The KGPS energy-saving medium-frequency power supply manufactured by Kangda Electric Furnace can boost the furnace voltage up to 2,400V even under relatively low input voltages (380V), achieving the same energy-saving effect. It represents a cost-effective technical solution for small electric furnaces with capacities of 1 ton or less, featuring low investment, convenient maintenance, low failure rate, and significant energy-saving performance.
