Abstract

The invention relates to a high-voltage and large-current harmonics filter for a photovoltaic inverter system. The high-voltage and large-current harmonics filter comprises an iron outer shell, an EMI filtering system and an electric component in an LCL filtering system, wherein the iron outer shell is provided with three copper bar bus inlet wires and three copper bar bus outlet wires, the EMI filtering system is composed of a copper bar bus, a ferrite bead T, a magnetic steel assembly Z, a capacitor C and a resistor R. The EMI filtering system is used for restraining the electromagnetism interference, the LCL filtering system is used for restraining higher harmonics generated by a photovoltaic power generation system, three copper bar buses serve as circuit transmission media, wholly penetrate through the ferrite bead T and the magnetic steel assembly in sequence and are connected with electric points of other electrical components in a riveting mode, the current-carrying capacity can reach to 1,600 A, and the rated voltage is 480 V. The high-voltage and large-current harmonics filter is reasonable and compact in structure, reliable in work, good in stability, capable of effectively meeting and ensuring the using requirement for supplying high-quality electric energy to a social power grid of the photovoltaic power generation system and high in practicality.
