The filter reactor, also known as the DC smoothing reactor, is used for the DC side of the converter, and the DC current with the AC component flows through the reactor. Its function is to limit the AC component superimposed on the DC current within a certain specified value. It is also used for the DC side coupling of parallel inverters, reducing the intermittent limit, limiting the circulating current in the circulating current line, and limiting the current rise rate when the DC fast switch cuts off the fault current. It is also used in the intermediate circuit of current and voltage inverters. The DC smoothing can also be used for rectifying power smoothing to eliminate ripple.
Structural features | |
main structure | The DC smoothing reactor is mainly used in the circuit to improve the quality of the power grid and improve the power factor. The DC smoothing reactor produced by our company is made of high-quality imported cold-rolled silicon steel sheet. It is mainly composed of iron core and coil. composition |
iron core | The iron core is generally a two-core column structure. The two core columns are formed by stacking multiple silicon steel discus, and are separated by insulating plates to prevent the core from magnetic saturation. |
iron yoke | The iron yoke is a square yoke. After assembly, it is pressed up and down by the tensioning screw to reduce noise. |
heat dissipation | This product is dry self-cooling |
Product advantages | |
Insulation class | There are two insulation grades, F and H. |
