Self-healing low voltage shunt capacitor elliptical anti-harmonic filter type a plays an important role in ensuring the stable operation of the power system.
1. Harmonic filtering function
Filtering principle: The anti-harmonic filter forms a resonant circuit through a specific combination of capacitors and inductors, which can effectively absorb and suppress harmonic currents in the power grid. The elliptical design makes the capacitor have better frequency characteristics at high frequencies, thereby filtering harmonics more effectively.
Frequency response: The elliptical anti-harmonic filter can be optimized for specific harmonic frequencies during design to ensure high filtering efficiency at these frequencies and reduce the impact of harmonics on the power grid.
2. Reactive power compensation
Improve power factor: Self-healing low voltage shunt capacitors can provide reactive power compensation and improve the power factor of the system. This can reduce reactive current in the power grid, reduce line losses, and improve power grid transmission efficiency.
Optimize system performance: Reactive compensation can stabilize grid voltage, reduce voltage fluctuations, and improve the overall performance and reliability of the system.
3. Self-healing function
Self-healing characteristics: When encountering internal short circuit or overvoltage, self-healing capacitors can quickly repair through the internal self-healing mechanism, restore insulation performance, and prevent the fault from spreading further. This improves the reliability and life of the capacitor.
Extend service life: The self-healing function enables the capacitor to maintain stable operation under harsh operating conditions, reduce maintenance and replacement frequency, and reduce operating costs.
4. Anti-harmonic performance
Suppress harmonic voltage: Anti-harmonic filters can effectively reduce harmonic voltages in the power grid, prevent interference with sensitive equipment, and protect the stable operation of the power system.
Improve power quality: By filtering out harmonics, improve the power quality of the power grid, reduce voltage distortion and current distortion, and improve the overall performance of the power system.

Prevent equipment from overheating: Harmonic currents can cause equipment to overheat, and anti-harmonic filters can reduce these harmonic currents to prevent equipment from being damaged by overheating.
Protecting relay protection devices: Harmonics may interfere with the normal operation of relay protection devices, causing false operation or refusal to operate. Anti-harmonic filters can reduce the interference of harmonics and ensure the accuracy of relay protection devices.
6. System stability
Reduce voltage fluctuations: Harmonic currents can cause voltage fluctuations and affect system stability. Anti-harmonic filters reduce voltage fluctuations by filtering out harmonics and improving system stability.
Improve frequency stability: Harmonic currents can affect the frequency stability of the system, and anti-harmonic filters can reduce these effects and ensure the frequency stability of the system.
