Abstract

The invention discloses a single-bus wiring structure, and relates to the field of power supply and distribution. The single-bus wiring structure comprises a bus, which is used for connecting the output side of a main transformer, and comprises multiple sections of sub-buses, the multiple sections of sub-buses are connected in sequence, and the first section of sub-bus and the last section of sub-bus are connected to form an annular structure. According to the invention, the defects of low load capacity of the low-voltage side of the main transformer and unreliable power grid power supply areovercome, the load capacity of the low-voltage side of the main transformer can be improved, and the power grid power supply reliability is improved.

Description

technical field [0001] The invention relates to the field of power supply and distribution, in particular to a single bus connection structure. Background technique [0002] At present, with the continuous growth of the total power load and density in various cities, the function of the 220kV power grid is gradually transformed from power transmission to power distribution. The existing 220kV power grid low-voltage load supply capacity can no longer meet the electricity demand of users. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a single-bus connection structure, which can improve the load capacity of the low-voltage side of the main transformer and improve the reliability of power supply by the power grid. [0004] The single-bus connection structure according to some embodiments of the present invention includes: [0005] The bus bar i...
