Goz type if Furnace Harmonic special device is specially designed and manufactured for IF furnace user system, with obvious filtering effect. With the equipment input, the quality of power consumption has been improved obviously, and the power factor of receiving power has been increased to more than 0.95, which reduces the line loss of distribution network and increases the bearing efficiency of distribution transformer. High performance contactor and integrated protection control system are used to switch each filter branch, so that the equipment operation is simple, safe and reliable. It can improve the current impact caused by impulse load, reduce voltage fluctuation and suppress voltage flicker, improve voltage stability and improve voltage quality. In addition, the protection function is complete, with short-circuit protection, over-voltage protection, over-current protection, high operation reliability.
