SVG can at the operated within range of specified perception to specified capacitive, dynamically regulates continuously, meets power factor compensation to greatest extent and want, wider than the range of operation of SVC.SVC is impedance type characteristic, and output current linearly reduces with busbar voltage, and SVG is insensitive to system parameters, fail safe and good stability, current source characteristic, exporting reactive current does not affect by busbar voltage, when system voltage step-down, SVG can also export the reactive current close with rated condition.
At present, on market SVG product generally SVG power cell is adopted and is installed in rack, rack is installed in indoor or container usually, the on-the-spot restriction being easily subject to careat.Meanwhile, the linear quadratic control signal of existing SVG power cell is generally easily subject to the interference of a signal, and reliability exists certain hidden danger.
Utility model content
The purpose of this utility model, be to provide a kind of close-coupled chain type SVG power cell, cellular construction is compact, and control signal is not disturbed, and is convenient to modularization assembling.SVG power cell is the core component of SVG system.
In order to reach above-mentioned purpose, solution of the present utility model is: a kind of close-coupled chain type SVG power cell, it is characterized in that, comprise Control card assembly, busbar, electric capacity, radiator, exchange into copper bar, exchange out copper bar, IGBT unit and square resistance, wherein, IGBT unit and square resistance are fixed on spreader surface, exchange into copper bar with exchange out copper bar and be electrically connected with IGBT unit respectively, electric capacity is located at bottom radiator respectively, busbar realizes the electrical connection of electric capacity and IGBT unit, and Control card assembly is laid in IGBT unit top.
In such scheme: described Control card assembly is positioned at a closed metal shell.
In such scheme: described electric capacity adopts membrane capacitance.
In such scheme, described electric capacity has 5.
In such scheme: described exchange into copper bar with exchange copper ranking in same height.
In such scheme: described busbar shape is Z-shaped.
After adopting such scheme, the utility model has following characteristics:
