Product working principle

The product consists of intelligent components, synchronous switching switch electrical components, current sampling components and low-voltage power capacitors. The following figure shows the working principle of the phase separation compensation method in the product series.

Product wiring diagram

The products are assembled in the cabinet and form a reactive automatic compensation device, which breaks the structural mode of the traditional automatic compensation device. As shown in the figure below, it has excellent functions such as zero-cutting of the capacitor and the structure is simple, and the same cabinet can hit more electricity. Capacity, easy production, good capacity adjustment, convenient operation and maintenance.

The maximum compensation capacity of 1000mm wide reactive power compensation cabinet: 800kvar; the number of installed machines: ≤20
Maximum compensation capacity of 800mm wide reactive power compensation cabinet: 600kvar; installed number: ≤16
