A method, device and server for optimizing the configuration of conductive loops at partitions of ring network cabinets

Abstract

The invention relates to a method and device for conductive loop configuration optimization at the position of a ring main unit partition and a server. A simulation model is established; grid division is performed on the simulation model; in the simulation model after grid division, a target model is selected; an electric field and current density of the simulation model are calculated by applying a simulation voltage and a simulation current to the target model; if the electric field and / or the current density is larger than a corresponding determination threshold, the simulation model is modified according to an adjustment policy; and if the electric field and the current density is smaller than or equal to the corresponding determination threshold, a ring main unit conductive loop configuration result is generated according to the simulation model. Quantitative analysis can be performed on the electric field and current density of a ring main unit, a mode of configuring a ring main unit conductor is effectively optimized and adjusted, the electric field and current density of the ring main unit are reduced, and reliability is improved.

Description

technical field [0001] The disclosure relates to the technical field of electric power equipment, and in particular to a method, a device and a server for optimizing the configuration of a conductive circuit at a partition of a ring network cabinet. Background technique [0002] Ring network cabinets are usually used for switching load currents, breaking short-circuit currents and transformer no-load currents, as well as charging currents for overhead lines and cable lines at a certain distance. They play a role in control and protection. They are important switching devices for ring network power supply and terminal power supply. . In industrial and mining enterprises, residential quarters, ports and high-rise buildings and other AC 10kV power distribution systems, the high-voltage circuits usually use load switches and are equipped with high-voltage fuses for protection. [0003] At present, a circuit breaker room is usually installed in the ring main unit, and each circu...
