I want to ask a few questions about the T connection of the ground ring network cabinet!

1.9 500kVA box transformer, indicating that the load is scattered; 2. Without two power points, there is no ring network; 3. It seems rare to have a central cabinet on the hoist station; The value of 4.2000kVA may be misunderstood by the landlord; Guess the data corresponds to the capacity of a single transformer (in this case, the data may be wrong, and if a single transformer exceeds 1000, it will basically go to the central cabinet for comprehensive protection), not the total capacity in the ring network mode; To sum up, if the power supply project in this community is a double power supply point and has a secondary load, it is still recommended to adopt the single-ring network power supply mode. Open and close the load switch cabinet, without protection, two in and two out (such as the design quantity, six cabinets may meet the requirements), each box is equipped with a set of ring network cabinets, one in and two out (standard on three sides); I'm afraid there is no need to consider metering to households, box transformers and switching stations; Of course, if local practices require special changes to property, that is another matter.
