The ZXPH330 commutation switch type three-phase imbalance control device is a real-time and intelligent automatic load regulation system that performs on load commutation scheduling for single-phase loads, effectively solving the problem of three-phase imbalance in low-voltage distribution networks.
1, equal voltage 0 milliseconds seamless commutation technology, commutation without interruption of power supply.
The commutation time is 0 milliseconds, and the commutation time is accurate and controllable. The commutation process is completed by the power electronic device, and no arc is generated. After phase commutation, the permanent magnet switch keeps steady state without loss
2, there is no surge flow in the commutation process, and the commutation is stable and reliable.
Since the commutation time is 0 milliseconds, the phase jump of the commutation process is only 120° at the moment when the two phase voltages are equal, which is a natural commutation, so there is no voltage mutation and no surge current.
3. Locate the phase commutator to ensure that each branch of the distribution network is balanced segment by segment.
The unique segmented voltage drop synthesis algorithm gives priority to adjusting the inverter closest to the extreme value of the line unbalance, thus ensuring the optimal balance of each part of the line, more effectively reducing the neutral current and increasing the end supply voltage.
4, no adverse effect on all kinds of electrical equipment.
Equal voltage 0 ms seamless commutation technology, will not cause power supply interruption and voltage dip, does not affect the user's power consumption; Stable and reliable commutation for inductive, capacitive and resistive loads
