Smart box changes from the high-voltage unit, transformer unit, low voltage unit, arranged into the form of "eye" shape and "goods" shape. Depending on the program, high voltage can be set to ring type, terminal type, and dual power line and other forms; it applies to three-phase AC rated voltage 3 ~ 12kV, rated frequency 50Hz power system, as the acceptance and distribution of electric energy and circuit implementation of control, protection and detection devices. Product Design Features 1. Case reference of foreign advanced technology and designed according to the actual situation. Has a strong, heat ventilation, good performance, dust, small animals, moisture, appearance, easy maintenance. Case material has a variety of options. Such as: aluminum, steel, composite panels, stainless steel, non-metallic materials (glass fiber cement) and so on. 2. Generally use the high side load switch, vacuum circuit breakers can also be used, and there is a full range of capabilities to prevent misuse. Device can be used XGN15-12 SF6 Ring Main Units, HXGN2-12 RMU, XGN66-12 metal-enclosed switchgear and other open switchgear as a high side power distribution unit, the low pressure side can choose GGD.GCK, MNS, GCS, etc. as output unit switchgear, transformers, transformer oil can be used or dry type transformers. 3. Improve substation protection performance, easy operation, high and low pressure metering selectable, can be fitted with automatic reactive power compensation device requirements. 4. Case designed to cover two-layer structure is laminated between the foam filled, having good thermal insulation. High and low pressure chamber in its interior design separate roof, indoor transformer with anti-condensation and automatic temperature monitoring, heating, cooling devices. 5. Box with natural ventilation, forced ventilation equipment can also be added. Corresponding lateral side door and shutters fitted with anti-dust position. 6. Low pressure switch can be smart meters and other devices to communicate with the host computer, to achieve "four remote" (remote control, telemetry, remote adjustment, remote), always on the device operation status monitoring, intelligent automation.
