    APPLICATION RANGE

    ZSMJ series smart capacitors are a new generation of reactive power compensation equipment for high-efficiency energy-saving, low-line loss, power factor and power quality in low-voltage distribution networks. It consists of intelligent control unit, thyristor composite switch circuit, line protection unit, and a low-voltage power capacitor. It replaces conventional intelligent controller, fuse, composite switch or mechanical contactor, low-voltage power capacitor and other parts in the cabinet. An automatic reactive power compensation device composed of a wire connected to the cabinet surface. It is of great significance to stabilize the system power grid, reduce the reactive power loss of the power grid and improve the service life of the capacitor, and achieve energy conservation and environmental protection.

    FEATURES

    (1) Automatically collect the voltage, current, active and reactive parameters of the circuit, and detect harmonics;

    (2) Perform reactive power compensation control algorithm calculation according to the acquisition parameters, and determine two-stage and cyclic switching of a single smart capacitor;

    (3) It has over-voltage, under-voltage, short circuit, over-current, over harmonic, three-phase unbalance, over-temperature protection and self-diagnosis function;

    (4) With communication interface, it can upload capacitor operating condition parameters and circuit real-time information.

    (5) Select the intelligent reactive power compensation controller working mode: when multiple intelligent capacitors are used in parallel, the operating conditions of each capacitor can also be accepted through the network and the intelligent reactive power compensation controller. Parameter setting and control commands for intelligent reactive power compensation controller.
