SMR-CZ series smart capacitors are a new generation of reactive power compensation equipment for 0.4KV low voltage distribution network with high efficiency, energy saving, reduced line loss, improved power factor and power quality. It consists of intelligent measurement and control unit, thyristor composite switch circuit, line protection unit, one (△ type, internal split two way) or one (Y type) low voltage power capacitor. It replaces the automatic reactive power compensation device which is composed of intelligent controller, fuse, composite switch or mechanical contactor, thermal relay, low-voltage power capacitor, indicator light and other parts connected by wires in the cabinet and the cabinet surface. The traditional reactive power compensation device has changed the bulky and cumbersome structure mode, so that the new generation of low-voltage reactive power compensation equipment has better compensation effect, smaller volume, lower power consumption, lower price, more cost saving and more use. Flexible, more convenient maintenance, longer service life and higher reliability, adapt to the higher requirements of modern power grid for reactive power compensation.
Zero-crossing switching, split-phase compensation (phase-separated smart capacitor), intelligent network, building block structure, simple wiring, convenient expansion, convenient maintenance, and remarkable effect.
