Cintrong 1250kVA new intelligent contactless voltage regulator (ZBW-S1250kVA) exported abroad, 3 sets of the voltage regulator regulates the three-phase electricity, the accuracy is 2.5%, fully meet the work of electrical equipment.
When high-power electrical equipment is working, the grid voltage is lowered, and the equipment cannot operate normally, especially in the process of starting the electric equipment, the problem of large in rush current needs to be solved.
Cintrong's new intelligent contactless regulator combine of IGBT and SCR, three-phase electrical series into the isolation transformer, using IGBT chopper to inject 0-20% of the isolation transformer (with the phase AC220 as the reference, a wider voltage range can be customized) voltage to compensate for the phase electricity. Combined with the SCR's commutation circuit, input voltage buck compensation or boost compensation can be realized.
