1,Accurate zero crossing cutting
No surge current when closing, zero crossing voltage input, zero crossing current cut-off, no overvoltage breakdown, no arcing or reignition phenomenon;
2,Complete protection function
With over voltage, under voltage, loss of voltage and short circuit protection, body over temperature protection, power grid harmonic content test and other functions, extend the service life;
3,Hierarchical control technique
Reactive power flow prediction and delayed multi-point sampling technology are adopted. According to power factor and reactive power, when the power factor is lower than the set value, the switching is controlled according to the load reactive power deficiency to ensure that the switching does not oscillate.
4,Automatic networking and online connection
Multiple building blocks are used in a modular manner to automatically generate main and auxiliary systems; The failure of the slave machine does not affect other work, and the failure of the host machine automatically exits, generating a new host and forming a new system work, with a high degree of intelligence;
5,On-line communication function
Network line 485 communication type online, easy to use, fast communication rate;
6,Communication control function
Can be connected to external controller, according to the communication command to carry out the operation or return;
7,Harmonic suppression function
It can effectively inhibit the high-order harmonic inrush current, form a low-impedance path to avoid capacitor overload,overheating, slow down aging, and reduce the failure rate;
8,Hybrid compensation function
Under the condition of three-phase unbalance, the hybrid compensation method is adopted. According to the reactive power deficiency of each phase, the reactive power optimization can be achieved by switching the hybrid compensation separately.
