Circuit and wiring of low-voltage distribution cabinet!

The rated current of the low-voltage distribution cabinet is 50Hz AC and the rated voltage is 380v V V. The distribution system is used for power conversion and control of power, lighting and distribution. The product has the characteristics of strong breaking ability, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong series and practicality, novel structure and so on.

ABCN is ABC three-phase power supply, and n is zero line! UA UB UC N on the right is the voltage measuring interface connected to that module, and DATA+ and DATA_ are a set of power supplies for the module! +5V and GND are also a set of power supplies, which should also be DC power supplies.

Main building

The basic structure of the cabinet is the combined assembly structure. Bolt connection, 20 mm modular installation hole equipment function room isolated from each other. The basic feature of GCK cabinet is that the busbar is at the upper part of the cabinet, and its compartments are divided into functional unit room (in front of the cabinet), busbar room (at the top of the cabinet) and cable room (behind the cabinet). It is also reliable for wall installation. At this time, the right side of the cabinet is widened by 200 mm as the cable room, which is similar to the top bus style of MNS cabinet.
