Commutation Switch

The commutation switch type three-phase load imbalance automatic adjustment device, through the three-phase intelligent commutation switch system (mainly composed of a controller and multiple commutation switches), adopts zero-crossing switching technology, which can quickly and accurately detect low-voltage power distribution For the system's three-phase imbalance problem, the single-phase load is adjusted without power failure in real time, so that the three-phase load of the station area is in a relatively balanced state, and at the same time, it effectively suppresses safety hazards such as single-phase overcurrent and terminal low voltage.
