High-voltage Passive Power Filter
Main Technical Characteristics:
- Complete protection functions, having equipped with the capacitor bank microcomputer protection unit: including the protection functions for overcurrent, short-circuit, overvoltage, low voltage, phase difference and neutral point unbalanced current (double star wiring);
- Equipped with a discharge coil, the filter is able to reduce the residual voltage at both ends of the capacitor below 50Vwithin 5s after the capacitor exits from the power grid;
- Designed by specialized simulation software, the filter is able to avoid harmonic amplification and syntony with the system; the harmonic filtering rate can reach 60-80%;
-The filter is designed according to the best scheme after the computer simulation calculation based on the actual measured data of the system, in order to ensure the highest cost performance;
- Each branch consists of a vacuum switch, a filter capacitor, a filter reactor, a discharge coil, and a lightning arrester.
- It is equipped with a dedicated controller for the filtering device to switch;
- There is complete monitoring, control, display and protection functions;
- While filtering the harmonics, the filter provides the fundamental wave reactive power that the system needs, compensates the inductive reactive power, and improves the power factor of the system.
Main Technical Parameters:
- Rated voltage: 6-110kV;
- Capacity range: 100kvar ~ 30000kvar;
- Wiring method: star connection;
- Filtering times: 3, 5, 7, 11, 13, etc.;
- Installation method: outdoor frame type.
