Compensatory capacitor series reactor
Low voltage series reactors are used in low voltage reactive power compensation cabinet and connected with capacitors in series.
With a large number of harmonic sources such as rectifier and converter devices, the higher harmonics generated will seriously damage the safe operation of the main transformer and other devices.
When the reactor is connected with the capacitor in series, it can effectively absorb the harmonic of the power network, improve the voltage waveform of the system, and improve the power factor of the system.
It can effectively restrain the inrush current and operate the overvoltage and effectively protect the capacitor.
The product is divided into three phases and two single-phase, all of which are iron core dry type.
The silicon steel sheet is made of imported cold rolled silicon steel sheet with high quality and low loss. The core column is divided into uniform segments by multiple air gaps, and the air gap is high temperature and high strength.
The adhesive is tightly bonded to each segment of the core column and the upper and lower iron yoke. The coil is made of aluminum foil coil or copper wire, and is tightly arranged.
Dense and uniform, large intercept flow and good linearity. The reactor is always in the range in the harmonic environment. The product is small in size.
Light weight, beautiful appearance, easy installation in cabinet without maintenance
