Product Description
Product characteristics and Application
With the rapid development of modern industry, a variety of non-linear and time-varying electronic power devices have been widely used. Harmonic components in power system have increased significantly. Harmonic pollution has become one of the main factors affecting power quality.
From the working principle, there are three main types of harmonic generation:
Ferromagnetic saturation type
Transformers, reactors, transformers, etc. The saturated current of the core and the inrush current of the excitation galvanometer are non-positive harmonics when the input voltage is restored.
Electronic switch type
Rectifiers, inverters and thyristor switchgear, etc. Metallurgical, electrified locomotive and other enterprises, as well as household, energy-saving lamps and power system DC transmission are all harmonic sources. The characteristic harmonics are mainly related to the pulsation number of the rectifier. The 6-pulsation rectifier generates 6k=1th harmonic and the 12-pulsation generates 12k+1th harmonic.
Arc type
Steelmaking furnaces, metal melting equipment, welding machines, etc. Harmonics vary with the working state of the equipment. |
