►Application fields
Output reactor
When the distance between the frequency converter and the motor exceeds 50m, the leakage current is too large due to the parasitic capacitance effect of the long cable to the ground, and the frequency converter is prone to over-current protection. At the same time, in order to avoid motor insulation damage, the output reactor must be added for compensation.
Output side noise filter
Output noise filter can reduce the radio noise caused by the cable between the inverter and the motor and the leakage current of the wire, as shown in the following figure:
Energy feedback unit
The energy feedback unit can feed back the electricity generated by the motor in the regenerative braking state to the power grid. Energy feedback unit uses IGBT for rectification feedback. Compared with the traditional three-phase parallel bridge rectifier unit, the harmonic distortion component of the feedback power grid is less than 4 % of the fundamental wave, and the pollution to the power grid is very small.The feedback unit is widely used in oil field pumping units, centrifuges, hoists and other equipment.
Connection of common DC
In the application of multi-motor transmission such as paper-making machinery and chemical fiber, the scheme of common DC bus is generally adopted.At a certain moment, some motors are in electric operation, while others are in regenerative braking ( power generation ). At this time, the renewable energy is automatically balanced on the DC bus and can be supplied to the motor in the electric state, thereby reducing the electric energy absorbed by the whole system from the power grid and achieving the purpose of energy saving.
The following is a schematic diagram of two motors working at the same time ( such as winding and unwinding motors ), one of which is always in the electric state and the other is always in the regenerative braking state.The DC buses of the two frequency converters are connected in parallel, and the renewable energy can be supplied to the electric state, thus achieving the purpose of energy saving.
