The invention discloses an intelligent and reliable urban power distribution network frame structure, and the structure comprises a plurality of switching stations, wherein in an A+ type power supplyarea, the switching stations adopt double-ring network closed loop running belt ring interlink lines to form two groups of double-ring networks, two independent single buses are adopted in each station, and a full-circuit-breaker mode is adopted for a 10kV switch; or the switching stations adopt a double-ring network closed-loop operation mode to form a group of double-ring networks, and each switching station is provided with a bus tie line for automatic switching operation; and the inter-ring connection line is used for load transfer in a planned power failure or fault state of the 10 kV busof the power transformer substation. According to a compressed power supply shelf, a cable demarcation room and a user total distribution room are cancelled, and each user distribution room is directly operated by the switching station. The switching stations take the functions of the cable demarcation room and the user total distribution room into account. No measuring point is designed, and themeters are dispersedly arranged in a 10kV metering cabinet at the front end of each distribution transformer in a user distribution room.
