Our low voltage transformers are widely used in industrial applications and in commercial and public buildings. They are also used for adjusting the voltage from 690 V to 400 V or as isolation transformers with a voltage ratio of 1:1, providing galvanic separation.
It is suitable used for electric circuit of AC 20Hz to 400Hz and voltage below 1000V, and is wide used in electric Used in the industrial, mining enterprises, power plant, airport, skyscraper etc fire prevention and require the higher place. For lighting electric facilities, the power of motive force, the power of rectification is used.
three phase ac output reactor the output reactor can provide overload protection for the line power supply and reduce the current harmonic distortion of the inverter; Improve the power factor of the input power supply, reduce the harmonic wave and suppress the surge of the inverter on the power supply equipment.
Access series reactor, capacitor voltage coefficient K=1 d 1 as K= 6% 1.06 10.06 1 ≈ -d = operating voltage is increased by 6%, with about 6% working current. The operation experience that the reactor equipped with a series capacitor capacity of 2/3 and above, will not produce the harmonic resonance, can effectively absorb harmonics, improve the voltage waveform of the system, improve the power factor of the system, and can effectively restrain the inrush current and over-voltage, effectively protect the capacitor.
The input reactor can provide overload protection for the line power supply and reduce the current harmonic distortion of the inverter; Improve the power factor of the input power supply, reduce the harmonic wave and suppress the surge of the inverter on the power supply equipment.
Reduce the current ripple in DC circuit, ensuring continuous current when induc-tance value reach to a certain degree. Reduce and prevent the rectifier bridge damage and capacitance overheating caused by pulse current. Improve power factor, reduce the AC pulse to the DC busbar. Limit grid voltage transient.
