Excellent AC frequency conversion power supply has what characteristics
1000kW load bank
1. Good speed regulation stability and high efficiency. At low speed, the characteristic static shut-off rate is higher and the relative stability is good.
2, large speed range, high precision.
3, small starting current, no impact on the system and power grid, good energy saving effect.
1000kW load bank
4, frequency conversion AC power supply is small, easy to install, debugging and maintenance.
5, the process is easy to automate.
6, need to use special inverter power supply | stabilizer, the cost is higher.
7, constant torque speed regulation, the overload capacity of the motor in the low speed section is greatly reduced.
There are three speed adjustment modes for AC power supply: pole change speed regulation, change slip rate speed regulation, and frequency conversion speed regulation. Among them, frequency conversion speed regulation has the most advantages. Here only a comparison between AC frequency conversion speed regulation system and DC speed regulation system is made.
