Active Power Filter Harmonic basic major hazards: ? Increase load power facilities, reduce system power factor, reducing the effective capacity and efficiency of power generation, transmission and electrical equipment, resulting in waste equipment, waste and electricity line losses; - cause no reactive compensation capacitor resonance and harmonic current amplification harmonic treatment methods, resulting in a capacitor bank due to over-current or over-voltage is damaged or not in operation; · pulsating torque motor causes vibration, affect product quality and life of the motor; ? Since the eddy and skin effect, the motors, transformers, transmission lines and other produce additional power loss and overheating, waste of energy and accelerated aging of insulation; * harmonic voltage is proportional to its peak voltage of the electric field strength in the form of enhanced dielectric, reducing equipment life ; Zero sequence (3 multiple times) harmonic currents can cause neutral phase four-wire system overload wind power harmonic control, and produces circulation in the delta-connected transformer windings, the winding current exceeds the rated value, even when serious accidents. · Harmonics will change the operating characteristics of protection relays, malfunction protection facilities, such as automatic device operates on Protection disorder; · harmonic voltage or current change change change rate and peak, slow arc extinction, influence breaker breaking capacity; · make Metering especially induction meter produce measurement error; · interference from adjacent power electronics, industrial control equipment and communications equipment, affecting the normal operation of equipment. BDKJ-FC I type compensation device the main features of 1, the main parameters of the device is based on parameters of power distribution equipment and usage, harmonic measurements and computer simulation by the set to ensure that the economic and technical means optimum performance. 2, configure harmonic controller, along with changes in the load of the device automatically adjust their working status harmonic control, to maintain optimum operating point harmonic control manufacturers, but also guaranteed to be greater than the power factor compensation device 0.9.3, filter capacitor unit consists of more than one capacitor, a single filter capacitor for single-phase structure phase tuning. Full membrane filter capacitors composite media, with a small, low loss, low operating temperature. 4, filter reactor type air core single coherent structure, the inductance value ± 5% adjustable, the reactor can be 'one' shape or 'product' shape horizontally. 5, in the form of complete sets of equipment filter flexible structure, can be framed cabinet or, when using the frame structure, with a fence isolate the entire device. 6, the filter device designed for manual and automatic two control mode, make the operation simple and safe. 7, according to the user's system requirements, effectively filter grid high harmonics, reactive power compensation, improve voltage quality. 8, filter compensation branch in strict accordance with the technical conditions to ensure the device is stable and reliable production and long-term operation.
