At present, there are many types of low-voltage switchgear cabinets on the market, and the appearance and structural form of cabinet manufacturers also have their own characteristics. It is difficult to combine cabinets in project expansion or reconstruction. State Grid began to promote the standardization of low-voltage switchgear. Through the standardized design, not only the overall quality of low-voltage switchgear can be improved, but also the user satisfaction can be improved. Features of this product: simplify classification, unify standards, break the original cabinet type classification, unify the structure, and realize the unification of cabinets; Considering the differences, the layout of main components and cabinets adopts the scheme that has been widely used in recent years and can represent the future development direction. At the same time, considering the de-differentiation configuration, the miniaturization cabinet type, SVG compensation, and communication interface are optional options for users to choose; The rated current sequence, protection level, reactive power compensation device, emergency power interface, nuclear phase device and feeder load monitoring of the switchgear have been properly designed in advance to adapt to the future level transformation requirements of the distribution network, achieve the goal of one-step completion after the equipment is put into operation, and avoid frequent upgrading and transformation; Simplify operation and maintenance, improve efficiency, and carry out unified and optimized design for the structural layout, size design, insulation protection and installation method details of cabinet door hinge of the switch cabinet to facilitate the inspection and operation of operation and maintenance personnel, reduce periodic operation and maintenance projects, and further improve work efficiency.
