Features of capacitor device

The product integrates the independent research and development achievements of sensing technology, network technology and electrical technology into intelligence, miniaturization and modularization product. Compared with traditional low-voltage reactive power compensation products, it has automatic cyclic switching, three-phase compensation, phase-splitting compensation, hybrid compensation, grading optimization compensation, hybrid grading optimization compensation. And it also has protection function of overcurrent, overvoltage, undervoltage, undercurrent,voltage loss and phase loss, harmonics, temperature. And at the time it has measurement, control , communication and other functions.

The product breaks through the existing low-voltage reactive power compensation equipment in structure, and realizes a new mode of decentralized control and centralized management. The compensation series has the characteristics of few components, low temperature rise, small size, low power consumption, no harmonic generation; brief structure, easy standardization, flexible configuration of capacity, safety, reliability, economy, and convenient use.

The product can predict the input capacitor, improve the active power of distribution transformer, reduce investment in capacity expansion, and reduce the loss of compensation system. The real-time switching of decentralized control increases the stability of the compensation system, and the zero-crossing control reduces the impact of inrush current on the system voltage, reduces equipment loss and increases the service life of capacitors for stabilizing the system power grid, and is of great significance to energy conservation and environmental protection.
