It is capacitive under power frequency, so as to prevent parallel resonance and non amplification harmonic current. It can suppress high-order harmonic, limit switching inrush current, improve system power factor, prevent harm caused by harmonic capacitor, and avoid excessive amplification and harmonic of grid harmonic caused by the connection of capacitor device.What is the function of Series reactor ?1. Reduce the switching inrush current of the capacitor bank and the amplitude of the inrush current transient process, which is conducive to the arc extinction of the contactor.2. Form full resonance circuit with capacitor bank to filter out characteristic subharmonics.3. Reduce the discharge current from the capacitor bank to the fault capacitor bank and protect the power capacitor.How to choose reactance rate of series reactor ?1. When the background harmonics connected to the power grid are 3rd order and above, it is generally 12%; two reactance rates of 4.5% to 6% and 12% can also be used.The third harmonic content is small, and a series reactor of 0.1% to 1% can be selected.The third harmonic content is relatively large and has already exceeded or approached the national standard limit, generally 12%; 4.5% ~ 6% and 12% can also be used.2. When the background harmonics at the access point of the compensation device are the third harmonic content is small and the fifth harmonic content is large, select a series reactor of 4.5% to 6%.The 3rd harmonic content is slightly larger, and the 5th harmonic content is smaller. Select a series reactor of 0.1% to 1%.The third harmonic content is relatively large, and has already exceeded or approached the national standard limit. Choose 12% or 12% and 4.5% to 6% series reactors for the mixed installation.3. The 5th harmonic content is small, and 4.5% ~ 6% series reactor should be selected.The 5th harmonic content is large, and a 4.5% series reactor should be selected.What kinds of Series reactor do we have?Oil immersed , Air core reactor and Iron core reactor.Oil-immersed Series reactorWhat are the advantages of Oil-immersed Series reactor ? 1. The product is oil immersed self cooling type, which has the characteristics of compact structure, small volume, light weight, simple installation and maintenance, and is suitable for outdoor use;2. It adopts high-quality transformer oil, high-voltage dispensing cable paper and corrugated electrical insulation paper as the main insulation, with excellent insulation performance. The oil tank is corrugated or radiator, circulatingGood heat dissipation, low temperature rise of core and coil, excellent electrical performance.
