To achieve these goals, the utility model comprises cabinet, be provided with bus unit, control unit and multi-channel compensating system unit in the cabinet, control is connected with the bus unit every road compensating unit with thyristor by the air switch in the control unit, every road compensating unit is capacitor and/or reactor, be characterized in: cabinet is a drawer unit formula structure, every road compensating unit is separately positioned in the drawer unit, and air switch and the thyristor of controlling every road compensating unit are arranged on the corresponding drawer unit.
The top of above-mentioned cabinet is provided with air exhauster, is provided with the air channel in the cabinet, and each drawer unit is provided with ventilating opening.
Also be provided with the vertical busbar that is connected in the bus unit in the above-mentioned cabinet, vertical busbar is outside equipped with the busbar case, and the compensating unit in each drawer unit is connected with vertical busbar with thyristor by corresponding air switch.
Thyristor on above-mentioned each drawer unit is connected with control unit by being arranged on drawer unit secondary terminal; Air switch on each drawer unit is connected with vertical busbar by a plug-in unit that is arranged in the cabinet.
Be provided with cell separators between above-mentioned each adjacent drawer unit.
Compared with prior art, the utility model functional unit drawer is provided with propulsion system, divides and to pull out board-like and two kinds of rocking handle types, and dust panel is provided with guide rail, operates light; Switch knob is located at drawer panel.Drawer can't not opened and take off to the section breaker drawer door, and mutual mechanical interlocking has been avoided the possibility of misoperation, and is safe and reliable; Every loop element is loaded on single drawer unit and carries out modularization, help to the device functional unit back up and keep in repair, change during as the functional unit fault backup units again to after the breakdown maintenance as backup, also make things convenient for the production of factory.The cabinet frame design is adopted convenient and other device assembly unit of section bar (8MF).Also can independently install, aesthetic in appearance, degree of protection reaches the IP30 level.
