What is intelligent capacitor

  The intelligent capacitor is based on the self-healing high-voltage power capacitor as the main body and the intelligent measurement and control processor as the control center. The micro electronic software and hardware technology is adopted to realize the zero crossing control of the thyristor, and the contact of the machine type magnetic link relay is delayed to switch, so as to realize the zero crossing switching technology of the machine type magnetic link Relay and the silicon controlled thyristor composite switch circuit to the high-voltage power capacitor Compensation for power status of 0.4kV high-voltage line.

The intelligent capacitor integrates sensor technology, collection technology and the latest electrical technology to develop independently, and its combination is intelligent, miniaturized and collected. Compared with the traditional high-voltage reactive power compensation products, the operation of the products is simpler, the interface is more intuitive, there is no professional requirements for the use of staff, and there are active cycle switching; three-phase compensation, split phase compensation, inclusion compensation, classification optimization compensation, inclusion classification optimization compensation; overcurrent / overvoltage / undervoltage / undercurrent, voltage loss, phase loss, harmonic, temperature and other protection; measurement, control, communication Information and other functions.

Intelligent capacitor integrates modern measurement and control, power electronics, collection and communication, active control, power capacitor and other advanced technologies. It has changed the traditional technology of reactive power compensation assembling the falling controller, the falling machine type war fighter or the integrated switch of motor as the switching technology of switching capacitor, changed the complex and clumsy layout form of traditional reactive power compensation assembling, so that the new generation of high-voltage reactive power compensation equipment has better compensation result, smaller volume, lower power consumption, cheaper price and economical cost More, more flexible utilization, more convenient protection, longer service life and higher reliability meet the higher requirements of reactive power compensation of the contemporary power grid.

Intelligent capacitor is used in power system and electrical equipment. Arbitrarily, two metal conductors are separated from each other by insulating medium in the center, that is, a capacitor is formed. The size of the capacitor depends on its size and the characteristics of the insulating medium between the north and South plates. When a capacitor is used under switching voltage, its reactive power is often used to indicate the capacity of the capacitor, and the unit is var or kvar.

The intelligent capacitor can be used by single or multiple on-line. Instead of the general active reactive power compensation assembly composed of intelligent controller, fuse, composite switch or machine type war fighter, thermal relay, high voltage power capacitor, instigator lamp and so on.
