Abstract

The invention discloses a power input assembly for a high-power low-voltage SVG and APF, which comprises an A-phase branch, a B-phase branch, a C-phase branch and a panel which are arranged in parallel, and each of the A-phase branch, the B-phase branch and the C-phase branch comprises an external wire shield, a fuse, a main relay, a current-limiting relay, a current-limiting resistor and a reactor, the external wire protective cover, the fuse, the main relay and the reactor are sequentially connected along the straight line direction, the current-limiting relay and the current-limiting resistor are positioned on the outer side of the main relay, and the external wire protective covers of the A-phase branch, the B-phase branch and the C-phase branch are fixed on the panel. The invention has the characteristics of simple structure, low temperature rise, high reliability, small volume, low cost and the like.

Description

technical field [0001] The invention relates to a power input assembly, in particular to a power input assembly for high-power low-voltage SVG and APF, and belongs to the field of SVG and APF. Background technique [0002] Low-voltage SVG is used for reactive power control of low-voltage distribution grids, so as to reduce the power loss of the grid, improve the operation safety and efficiency of the grid, and improve the voltage quality of the grid. The low-voltage APF is used for harmonic control of the low-voltage power distribution grid, so as to eliminate the harmonic pollution of the grid and improve the power quality of the grid. Low-voltage SVG and APF have the same circuit structure, but write different programs. [0003] There are essential power input components in SVG and APF, including terminal blocks, protective fuses, on-off circuit switches, filter reactors, etc. For high-power and low-voltage SVG and APF, due to the large current passing through Power loss...
