ZRFC H.V.PASSIVE HARMONIC FILTERING EQUIPMENT

General introduction

The equipment is used for different voltage class (3.3~15kv), with capacity ranging from hundreds of kilovar to several ten thousand kilovar, which can be found widely used among metallurgy, mining, oil, chemistry, machine-making, light industry, and municipal construction as well.

Working principle

1.ZRFC series of high-voltage passive filtering device is composed of multiple LC filtering braches encompassing filtering capacitor, filtering reactor, free-inductance resistor,which is connected in parallel to the power network with nonlinear load.

2.All the filtering branches designs take key points into account including: the components and amount of harmonic and power factor compensation. For the harmonic, each filtering branch works the same as the low-resistance route way, making most relevant harmonic flow into this branch. In this way, the filtering gets done and also the voltage common point and current distortion get less. Besides this, the device can supply the power system with capacitive Var power to enhance power factor of the power system.

3.The equipment can be used for different voltage class (3.3~15kV), with capacity ranging from hundreds of kilovar to several ten thousand kilovar.device can supply the power system with capacitive Var power to enhance power factor of the power system.
