1. explosion-proof reactive power compensator of 1140V three level, it is characterized in that:

  • comprise switch activated module (3), three electrical level power module (4), control protection module (5), the main circuit of described three electrical level power module (4) adopts three level active neutral-point-clamped type power inverters;

    The input of 1140V ac bus (1) the described switch activated module of access (3), the input of output termination three electrical level power module (4) of switch activated module (3);

    Electric current, the voltage sampling signal that gathers in busbar voltage transducer (6), bus current transducer (7), three electrical level power module (4) is transferred to respectively control protection module (5), and the control signal of control protection module (5) output drives three level active neutral-point-clamped type power inverters in three electrical level power module (4).
