Application Fields
Ultra-high voltage transmission systems
Usage
Series — connected in series in parallel capacitor circuits to suppress closing inrush current, used in ultra-high voltage transmission system reactive power compensation networks to compensate for the distributed capacitance effect of long-distance transmission lines. By forming a series resonant circuit with the capacitor bank, it creates a low-impedance path for 3rd, 5th and other harmonics, directionally absorbs harmonic components, blocks resonant overvoltage caused by harmonic superposition, and ensures the insulation safety of power equipment.
Parallel — connected at the end of ultra-high voltage transmission lines or the low-voltage side of substations to suppress power frequency overvoltage by compensating capacitive reactive power of the line (such as voltage rise in lightly loaded lines) and maintain system voltage stability.
Main Technical Parameters
