Application field ●High-power rectification device: such as electrolytic aluminum, intermediate frequency furnace, rolling mill, etc., semiconductor devices will generate characteristic harmonics related to their wiring methods during the process of turning off and turning on, and the harmonic current flowing into the system will affect transformers and motors, etc. normal work, causing its overload or even burning. ●Electric locomotives: At present, most of the electrified railway locomotives used in operation in various countries use AC 25~35kV power supply, and some substations provide two-phase power supply. This will inevitably lead to three-phase load asymmetry, thereby injecting harmonic current and negative sequence current into the power system together. Generally, filters with the same capacity are installed on the two power supply arms of the traction transformer. ●Loads with ferromagnetic devices: such as transformers, iron core reactors, etc., when they work in a saturated state, due to the nonlinearity of the magnetization curve, a certain number of harmonics will be generated, of which the third is the main one. When the system has parallel When compensating the capacitor, an appropriate ratio between the capacitive reactance of the capacitor and the inductive reactance of the system will cause serious amplification of the third harmonic.
