DG series single-phase dry-type isolation transformers are generally applicable to circuits with AC 50Hz to 60Hz and voltages below 660V, used in important equipment, precision machine tools, mechanical electronic equipment, medical equipment, rectifiers, and lighting. The various input and output voltage levels of the product, the connection group, the number and position of the adjustment taps (usually ±5%), the distribution of winding capacity, the equipment of the secondary single-phase winding, the use of the rectifier circuit, whether it is required to bring The shell, etc., can be carefully designed and manufactured according to user requirements. Shielding can further avoid the high-frequency pulse interference (pulse and high-frequency noise) coupled by the transformer, which can effectively prevent it, but the transformer must be properly grounded and very strict, otherwise the anti-common mode interference will be ineffective.

It is suitable for communication, electric power, chemical industry, light industry and other industries. It can be used as lighting power supply, power supply, etc. Single-phase dry transformers are widely used in imported important equipment, precision machine tools, mechanical electronic equipment and other power transformers. At the same time, it can be equipped with a chassis and various switches, meters, indicator lights, etc.

Output Reactor

It is installed at the output end of the inverter, which is used to limit the capacitive charging current of the inverter and the motor connecting cable, and inactivate the voltage rise rate of PWM wave output by the inverter. When the length of motor cable exceeds a certain value, it is recommended to insert a motor reactor between the inverter and the motor, which is used to compensate the recharging current of capacitor in case of the long wires. The maximum length depends on the rated value of the frequency converter and the type of the motor cable.

Input Reactor

The input reactor can be used to provide improved overload protection for the line power supply, and to reduce the current harmonic distortion produced by the inverter. Increase the power factor of input power supply, reduce the high harmonic, and restrain the surge of frequency converter in the power supply equipment

DC Smoothing Reactor

DC smoothing reactor is used in the rectifying circuit to restrain the ripple pulse component after rectification and make the rectified current continuous, so as to improve the output branch waveform and guarantee the normal operation of DC equipment. The smoothing reactor is used as the series reactor in DC machine supplied by the converter, in order to eliminate the DC link in the current and voltage DC link converter; It is supposed to decouple the converter components on DC side. The power converter on DC side has high pulse circuit feedback to reduce the difference value limit, so as to limit the ring current on the connection with ring current, at the same time, limit the the rising rate of current. The smoothing reactor adopts the iron core of TEM and TET or TPK air core reactor, depending on the requirements on electromagnetic induction.
