Application

This series of integrated intelligent power capacitors is a safe, reliable, high-efficiency and energy-saving installation installed in the reactive power compensation device. Its function is to reduce the transformer loss, the line loss of the power supply line, improve the power factor of the power system and improve the grid power The core component of a new generation of high-quality reactive power compensation equipment. It can also be used as a small compensation device with independent automatic control function.

The product is composed of: measurement and control unit, capacitor switching switch and arc extinguishing unit, comprehensive protection unit (with: system harmonic voltage/current limit, overvoltage/undervoltage, small current blocking, compensation for branch overcurrent and unbalance , Pre-warning and protection functions of data information such as over-temperature and over-pressure inside the capacitor), working status indicator unit, low-voltage parallel capacitor (up to 8 capacitors), circuit breaker, housing and communication terminals and other functional components, which are formed after optimized combination A highly intelligent product with integrated mechatronics.

The application of this product has changed the bulky and cumbersome structure and assembly process of the traditional reactive power compensation device, so that a new generation of low-voltage reactive power compensation device has: better compensation effect, smaller size, lower power consumption, and more use Flexibility, easier assembly and maintenance, higher operational reliability, longer service life, etc.
