ZBSG series rectifier transformer

The function of the rectifier transformer is to connect to the AC/DC power converter to convert the voltage on the power supply side into the voltage required by the load while providing electrical isolation between the load and the power supply side.

 

Product Features

1. The function of the rectifier transformer is to connect to the AC/DC power converter to convert the voltage on the power supply side into the voltage required by the load and to provide electrical isolation between the load and the power supply side;

2. According to ICE-146, circuit 2/8/10/15/19, there is only one secondary winding transformer (connection group is DYN11) suitable for operation in a 6-pulse rectifier;

3. According to ICE-146, circuit 3/4/5/6/11/12/16/1718, transformer with two secondary windings (connection group is DdOy11), electromagnetic decoupling, suitable for operation in 12-pulse Among the rectifiers, on the 12-pulse rectifier, since there are two bridge circuits, they are connected in parallel with 30 phase shifts.

 

Product performance

1. The insulation system complies with UL1446, and can also be designed according to user requirements;

2. The temperature rise meets the requirements of Class H, and the insulating material adopts Class H;

3. The rectifier transformer as a whole is impregnated with insoluble polyester resin under vacuum pressure (VPI), and then thermally cured in heat curing. The rectifier transformer is generally designed for natural air cooling. Forced air cooling can be designed according to user requirements. At this time, the shape of the transformer The size and weight will be reduced. This type of transformer is recommended to use air-cooled devices to ensure the operation of the transformer (especially the large-capacity transformer).

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.
