drive and computing devices. In addition, resonance and voltage distortion also cause power supply accidents. But, series reactor can improve this and avoid the faults.
The resonant frequency is lower than the lowest one of the system (usually 5 and 7 times) when the capacitor connects reactor in series. As a result, the circuit tends to be capacitive in power frequency and the power factor is improved; while the circuit is inductive in resonant frequency and coupled vibration can be avoided without worries of harmonic amplification. Excellent impedance matching can make capacitor bank absorb 30%-60% of harmonic current (such as 5 times).ternal safety device of automatic switch-off
Product Name:
ARS-RE Series Filter Reactor
Product Model:
RE7/15 RE7/20 RE7/25 RE7/30 RE7/40 RE7/50 RE7/60 RE7/75 RE14/15 RE14/20 RE14/25
Product Introduction:
Nonlinear current, mostly used and generated in modern power electronic devices, is affecting the power grid in the harmonic way with increasingly worse pollution, which causes overload and fault of capacitor, transformer and transmission equipment, as well as serious interference to
Product Features:
Low loss, high resistance to harmonic, high linearity to avoid magnetic saturation, low noise operation, easy installation, environmentally friendly, long service life, special temperature protection.
High-quality and low-loss cold-rolled oriented silicon steel sheet is adopted for the core; the stem is evenly separated by many air-gaps; and the air-gaps are separated by epoxy glass laminated sheets so as to ensure the reactor is unchanged in the process of operation.
Class H or C enameled flat copper wire is adopted for the coil with great performance and excellent heat dissipation.
Nonmagnetic materials are adopted for solid pieces of reactor stem so as to ensure that they have high quality factors and low temperature rise, as well as favorable filtering effect.
Anti-corrosion treatment is performed for exposed parts and tinning copper pipe terminals are used for leading-out terminals.
