Product introduction
The intelligent integrated harmonic suppression power capacitor compensation device based on low voltage power capacitor, high performance reactor, high reliable switch and control system adopts the latest technology. such as micro-electro-software, micro-sensor technology, micronetwork technology and electrical manufacturing technology, to realize low-voltage reactive compensation function and to make it work reliably, make it easy for zero-switching , protection, measurement, signal , on- line, etc. it is a major breakthough of low-voltage reactive automatic compensation filtering technology, mainly used in reactive power compensation, can operate reliably, does not produce resonance , and has no amplication effect on hamronic ,The product of the series of 7% reactor is used in the electric environment of 5 times, 7 times and above, and the product of 13% reactor is used in the electrical environment with the main harmonic for 3 times and above.
Products are mainly applicable to chemical industry , building materials, paper, textile , coal, electricity, telecommunications , aluminum , shipping ports , tobacco, wine, automobile manufacturing , precision electronics, precision machinery and other industrial areas. At the same time, it can also be used in the communication industry power supply system , securities trading power supply system , airpor port standby power supply system, large medical system, various ups/generator sets, exhibition venues, commercial office and other commercial power systems.
The product is composed of intelligent control system, composite switch, current sampling , dry series reactor and low voltage filter power capacitor.
Characteristics
Guo zero-switching: the voltage over zero,the current zero- crossing excision, the inrush current, the micro power consumption , the there is no arc and the harmonic injection, greatly improve the equipment's resistance to voltage, current impact, and reduce the energy consumption of 80% of the conventional capacitor cabinet .
Filtering function : effectively suppress high harmonic and inrush current , and form low impedance path for high order harmonic . it can eliminate the infuence of high harmonic on the capacito, protect the circuit and capacitor overload, prevent the capacitor from overheating, the aging of insulating medium, the self-healing performance, and the service life is reduced;
Intelligent network control: automatic detection and tracking of reactive power changes automatic switching capacitor banks. Capactors with the same capacity shall be switched according to the principle of circular switching. and capacitors with different capacity shall be cut according to the principle of adaptation;
Capacitor first cast first, first to return first, first to vote; The capacitor operation temperature is low first, the temperature is high first; When the compensation condition is constant,The capacitor is switched every time to avoid the long time operation of a single capacitor.
