The invention discloses a power distribution net rack wiring structure which comprises multiple switch stations and substations, wherein each switch
station comprises a first section of
bus and a second section of
bus connected in series through a section switch; each section of
bus is connected with an incoming line, multiple outgoing lines and a connection line respectively; two incoming lines of each switch
station are connected with different substations respectively; the connection line is arranged between the switch stations; one end of the connection line is connected with the first section of bus of one switch
station, and the other end of the connection line is connected with the second section of bus of the other switch station. The power distribution net rack wiring structure disclosed by the invention has flexible
operation mode and high reliability; with a centralized power supply mode of the switch stations, the operation and
maintenance management is facilitated; the incoming line and connection line of each switch station are configured with optical-
fiber longitudinal
differential protection, and the section switch and connection switch of the bus of each switch station are configured with spare power automatic switching and expansion spare power automatic switching, so that the fault
elimination of the distribution network and the power supply of the non-fault section can be accelerated, the fault-caused power failure time is reduced, the power supply reliability is improved, and the power distribution net rack wiring structure is suitable for the regions with insufficient medium-
voltage interval of substations, limited outgoing line corridors, centralized loads and high reliability requirements.
