Application of Wattless Power Compensation and Filtering Device in Intermediate Frequency Induction Furnace

Metallurgical industry is energy-hungry,especially in the intermediate frequency furnace,there is huge potential in energy saving。The filter and compensation device did not installed a intermediate frequency furnace due to harmonic quantity and the power factor is not up to the standard. In order to solve the problems,at the beginning of 2011 the two intermediate frequency furnace were designed and installed of compensation and filtering device.The power factor of the system is up to the standard and harmonic distortion rate controled in national standard after operation. Practice prove that the devices of the filter and compensation device has high economic benefit,can improve equipment reliability and production efficiency,both energy saving and environmental protection of the social benefits of power. It is worth to popularize.
