Medium frequency induction furnace

Medium frequency induction furnace

Intermediate frequency furnace power supply system is one of the biggest amount of harmonic in power system harmonic source, common has the power of the medium frequency furnace and high frequency induction furnace. The six pulse intermediate frequency furnace, mainly produce 5, 7, 11, 13 second-class characteristic harmonic; For 12 pulse converter medium frequency furnace, mainly produce 11, 13, 23, 25 inferior characteristic harmonic. In general, small converter device adopts 6 pulse, relatively large adopts 12 pulse. Such as furnace transformer connect/delta Y/Y type, or to use two electric furnace transformer power supply.
For intermediate frequency furnace filter unit, we have many successful running of equipment. General design of two or more circuit, combined filtering methods for harmonic governance:
1, according to different medium frequency furnace, provide you with special filter and reactive power compensation of complete sets of equipment;
2, according to different management goal, the demand of the actual working condition, we reasonable design filter compensation scheme for you;
3, according to the actual number of intermediate frequency furnace and the load distribution, reasonable design is a single governance medium frequency furnace, or more than one centralized management;
4, according to your actual demand of industrial, we reasonable design filter compensation scheme for you, to meet the diverse needs of your industrial and mining.
