ZCSPC three-phase load unbalance adjustment device

The ZCSPC three-phase load unbalance regulating device collects the load current in real time through the external current transformer (CT), and sends the system current information to the internal controller for processing and analysis, to determine whether the system is in an unbalanced state, and calculate the current value of each phase when it reaches the equilibrium state, and then sends the signal to the internal IGBT and drives its action. The unbalanced current is transferred from the phase with large current to the phase with small current to realize the three-phase balance function.

Core advantages:


1. Excellent compensation effect


φ0.99 reactive power compensation function;


Three-phase unbalance compensation function;


Appropriate voltage regulation function;


Capacitive load -1 ~ 1 compensation effect;


Effectively avoid the power rate and electricity penalty caused by failure to timely reactive power compensation.



2. Fast and stable real-time response


Real-time compensation, response time less than 15ms;


No overcomplement, no undercomplement, no resonance.



3. Modular design


Easy installation, easy commissioning, easy maintenance, easy transportation.



4. Combined application of multiple module functions


Separate SPC module: ① reactive power compensation; (2) three-phase unbalance compensation; ③ Reactive power compensation + three-phase unbalance compensation.


SPC module +APF module: SPC function + harmonic compensation.



5 . long service life


Design life of 100,000 hours, maintenance free.



6. A variety of communication methods


Comes with 485 communication interface;


Extendable Ethernet /WIFI/GPRS for easy maintenance and setting.
