Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of harmonic current suppression, specifically relates to a device for fixing on alternating current safe deposit box to suppress harmonic current. BACKGROUND

[0002] In the power system, the generation of harmonic current can seriously affect the power quality of the power grid, leading to voltage waveform distortion, voltage fluctuation and flicker, etc. It may also cause damage to the equipment in the power grid, leading to an increase in the temperature rise of transformers, motors and other equipment, and shortening the service life of the equipment.

[0003] In order to suppress the generated harmonic current, for example, the harmonic current suppressor disclosed in the authorization announcement No. CN2502382Y, which specifically discloses a harmonic current suppressor composed of silicon steel sheet, winding, etc. The silicon steel sheet adopts a "eye" shaped structure, two sets of working windings, i.e. the first winding and the second winding, are wound on the first middle foot and the second middle foot respectively, and the lead-out wire devices of the first wire frame and the second wire frame are arranged at the upper left and upper right respectively; there is a gap between the two opposite first middle foot group and second middle foot group.

[0004] Although the above-mentioned harmonic current suppressor can suppress harmonic current, there are still some deficiencies; for example, by installing winding, wire frame and lead wire device in the silicon steel sheet, the assembly of silicon steel sheet, winding, wire frame and lead wire device forms a complete harmonic current suppressor, which adopts more accessories and has a relatively complex structure, and is not convenient to assemble.
