Satons sine wave filter application in a petrochemical company case


2021-03-26

Satons (Shanghai) Power Supply Co., Ltd. solved the motor overheating problem caused by the excessively long connecting cable between the inverter and the motor for a petrochemical company.

 

Satons SWF sine wave filters are used in motor drives in many transmission systems (especially in inverters or switching power supply devices). Passive filters are designed to convert non-sinusoidal voltages generated by inverters, etc., to make the voltage The waveform forms a waveform similar to a sine wave. It is mainly used in industrial power grids ranging from 380 to 1140V. Because the voltage drop of this filter is much lower than the current market standard, it can guarantee a very high motor input voltage. It can reduce noise and protect relatively sensitive motors, allowing the use of very long motor cables, up to 2000 meters long.

 

Typical application industries: metallurgy, coal, petrochemical, water treatment, new energy, etc. Generally, if the distance between the domestic inverter and the load exceeds 50 meters, a reactor must be added. If there is a requirement for the output waveform of the inverter, a sine wave filter must be added; if the distance between imported inverters exceeds 100 meters , It is necessary to add a sine wave filter. This distance refers to the length of the connection. The manufacturing cost is relatively high. Usually, if there is no special requirement, it is enough to select a special filter or output reactor for the frequency converter.
