Electric reactor
Product description
The electric reactor is also referred to as the reactive power compensation reactor. It has the following functions: reduce the surge and the peak current, improve the power factor of the input side, inhibit the harmonic of the power grid and improve the input current waveform. The electric reactor is fabricated by winding the H-grade copper wires. It has the following characteristics: the linearity is high, the overload current capability is large, the voltage drop is large and the loss is low. Due to its good insulation performance, high pressure resistance, low noise level and long service life, this electric reactor has becomes the product for the over 100 well-known enterprises who are the strategic partners of the company.

The benefits after installation of this type of electric reactor
1: This type of electric reactor can protect the capacitors against the damages which are caused by the excessive current as well as excessive voltage due to the resonance in the system.
2: With this type of electric reactor, it will be possible to reduce the electricity bill and provide the power factor.
3: This type of electric reactor can protect the equipment from the damages to the equipment, which have been caused by the excessive current.
4: With this type of electric reactor, it will be possible to increase the utilization rate of the distribution system. After the reactive power compensation has been carried out, the active power of the system can be increased. As the result, the load of the new equipment can be increased.
5: With this type of electric reactor, it will be possible to increase the production efficiency, improve the power factor. As the result, the equipment operation will become more stable, and it will possible to produce better products.
Things to be noted for use:
At the time of selecting the matching electric reactor, the user must understand the number of the harmonic in the system and their sizes. Do not install any additional electric reactors without knowing the effect which may be resulted in. In addition, choose those capacitors with a high reliability at the same time. In case that there are three harmonics, the reactance rate of 6% or 7% is to be added to the system, it will amplify the harmonic current on the contrary and accelerate the damage of the component.
At the time when selecting the capacitors, the rated voltage must be higher than the system voltage. The reasons for this are as follows: when any additional reactor is to be installed, the voltage of the capacitor will be increased, and as a result, the aging of the capacitor will be speeded up, its service life will be reduced and it will be impossible for the filter device to carry out its normal operation.
