Modular apparatus for high voltage direct-current transmission system
The present invention relates to a modular apparatus for a high-voltage direct-current transmission system. A sub-module (10), which is a modular apparatus, comprises according to the present invention a power unit (12) in the front and a capacitor unit (13) in the rear, and on the lower end of a front surface (14′) of a power unit housing (14) forming the exterior of the power unit (12) is a sloped surface (15). The sloped surface (15) has a hexahederal shape created by removing the edge formed by the front surface (14′) and the bottom surface of the power unit housing (14) and faces the ground at an angle. A display unit (16) is provided on the sloped surface (15) so that the status of the sub-module (10) can be easily checked by a worker from the ground on which a structure stands. A front panel (18) comprising the display unit (16) is provided on the sloped surface (15), wherein the front panel (18) is provided with a panel through-hole (18′) to allow a configuration space (20) in the interior to be visible. A control board (22) is coupled to the front panel (18) by means of a connection block (23). The control board (22) is movably supported on either end thereof by support rails (26) provided on both inner side walls of the configuration space (20) so as to allow easy entry into the interior and exit to the outside of the power unit (12).
