(1) The cabinet frame is a general-purpose cabinet, which is bolted and assembled with new section steel, with high installation accuracy, convenient assembly, high strength and durability.
(2) The switch cabinet is divided into bus room, functional unit room and cable room by grounded metal partition. Each functional unit room is also isolated from each other by grounded metal plates without interference, which can effectively prevent the expansion of fault.
(3) The drawer unit is equipped with reliable mechanical interlocking device. Through the control of the operating handle, it has five obvious positions: on, off, test, isolation and extraction. When the drawer is pushed and pulled to the on, off, test and isolation positions, the drawer will be automatically positioned and locked. The next position can be entered only after the positioning is released.
(4) Drawers with the same rating and structure have good interchangeability.
(5) There are many power supply circuits, which can be flexibly combined, economical and practical. One cabinet can be equipped with 9 drawers of 1 unit or 18 drawers of 1 / 2 unit.
(6) There are 32 and 64 pairs of auxiliary contacts of drawer unit (20 pairs for 1 / 2 Drawer), which can meet the needs of automation and computer interface.
(7) The air gap and creepage distance of electrical components in the cabinet are large, and the insulation strength of the switchgear is high.
(8) Insulating parts with high tensile strength are selected in the cabinet to strengthen the strength of the fixed support of the cabinet body and busbar system and improve the dynamic stability.
(9) The horizontal bus of GCs type cabinet is arranged in the bus compartment behind the cabinet, and the rear of the cabinet is of sealing plate structure.
(10) The cabinet structure can consider that the cable enters the cabinet from the bottom and / or top of the cabinet.
(11) It can be equipped with intelligent interface device, which can be directly hung on the field bus or connected with DCS Ethernet through adapter to monitor at the operator station, which can not only improve the monitoring automation level, but also save a lot of control cables and reduce investment.
(12) The protection grade of the cabinet is high, which can meet the requirements of users for high protection grade.
