Introduction
A Smoothing reactor is a device or circuit that can process signals, connect in series with a filter capacitor, tune to a certain resonant frequency, and absorb the harmonic current of the corresponding frequency in the power grid. There are a large number of harmonic sources such as rectification, converter, and frequency conversion devices in the low-voltage power grid, and the high-order harmonics generated by them will seriously endanger the safe operation of the main transformer and other electrical equipment in the system. After the filter reactor and the capacitor are connected in series, it can not only effectively absorb the harmonics of the power grid, but also improve the power factor of the system, which plays a greater role in the safe operation of the system.

Product Features
Structural features
1. The reactor is divided into three-phase and single-phase, both of which are core dry type.
2. The iron core adopts low-loss cold-rolled oriented silicon steel sheet, the core column is divided into uniform small sections by multiple air gaps, and the air gap is spaced by an epoxy laminated glass cloth plate, and the reactance air gap does not change during operation.
3. The coil is made of H-class or C-grade enameled flat copper wire, which is tightly arranged and uniform, and the appearance does not cover the insulation layer, which has better aesthetics and good heat dissipation performance.
4. After the coil and core of the reactor are assembled into one, after pre-baking→ vacuum impregnation paint → hot baking during this process, using H-grade impregnating paint, so that the coil and iron core of the reactor are firmly combined, not only reduce the noise during operation but also have a high heat resistance level, the reactor can also run noiselessly at high temperature.
5. The fasteners of the core column of the reactor are made of non-magnetic materials, and the reactor has a high-quality factor and low-temperature rise, and has a better filtering effect.
6. The exposed parts are treated, and the exit terminal adopts a cold-pressed copper tube terminal.
7. Compared with similar products, the reactor has the advantages of small size, lightweight, and beautiful appearance.
Performance parameters:
1. It can be used for 400V and 660V systems.
2. Types of reactance: 1%, 6%, 12%
3. The rated insulation level is 3kV/min.
4. The temperature rise limit of each part of the reactor: the iron core does not exceed 85K, and the temperature rise of the electric coil does not exceed 95K.
5. The noise of the reactor is not more than 45dB
6. The reactor can operate for a long time under the power frequency plus harmonic current is not more than 1.35 times the rated current.
7. Linearity of reactance value: the ratio of reactance value under 1.8 times rated current to reactance value under rated current is not less than 0.95.
8. The difference between the reactivity values of any two phases of the three-phase reactor is not more than ±3%.
9. Temperature resistance grade H (180 °C) or above.
