(1) The main structure of the device adopts 8MF type steel, and the structure adopts two structural forms: assembly and partial welding.E=20 ㎜ on the main frame.
(2) The functional rooms of the unit are strictly separated, and the compartments are mainly divided into functional unit room, bus room and cable room. The functions of each unit are relatively independent.
(3) The feeder cabinet and motor control cabinet are equipped with special cable compartment. The connection between the functional unit room and the cable room is realized through the converter or copper row, which not only improves the reliability of the cable, but also greatly facilitates the installation and maintenance of the cables by users.
(4) The cable compartment has two width sizes (240 ㎜ and 440 ㎜) available, depending on the number of cables, cross section and user convenience and requirements for installation and maintenance.
(5) The functional unit auxiliary contact of the unit is 32 pairs of one unit and above, and 20 pairs of 1 / 2 unit, which can meet the needs of the interface between the automatic user and the computer.
(6) Considering the general safety of dry-type transformer and the economy of oil-immersed transformer, the device can easily form a group with dry-type transformer, or easily connect with the low-voltage bus of oil-immersed transformer.
(7)The drawer as the main body, with both the extraction type and fixed type, can be mixed combination, any choice.
