product description
It is used in series with the filter capacitor bank to form an LC resonant circuit, which is widely used in high and low voltage filter cabinets to filter out specific high-order harmonics in the system, absorb harmonic currents on the spot, and improve the power factor of the system. Power grid pollution, the role of improving the power quality of the grid.

Model Description
illustrate
1. The order h of the harmonic must be an integer multiple of the fundamental frequency 50Hz;
2. The periodic component whose frequency is an integer multiple of the non-power frequency is called a fractional harmonic, also known as an inter-harmonic, and an inter-harmonic lower than the power frequency is called a sub-harmonic;
3. The waveform of the transient phenomenon contains high-frequency components, but it is not a harmonic, and has nothing to do with the fundamental frequency of the system. Generally, the second harmonic is a steady-state phenomenon that lasts for several cycles, and the waveform continues for at least a few seconds;
4. Periodic notches (commutation gaps) in the voltage caused by the commutation of the converter device are not dry harmonics.
Technical Parameters
Features
●The filter reactor is divided into two types: three-phase and single-phase, both of which are iron core dry type;
●The coil is wound with F-grade or Japanese-grade wire or foil, and the arrangement is tight and uniform;
The clamps and fasteners of the filter reactor are made of non-magnetic materials to ensure that the reactor has a high quality factor and a good filtering effect;
●The exposed parts are treated with anti-corrosion treatment;
●Low temperature rise, small loss, high comprehensive utilization rate, easy to install.
