Abstract

The embodiment of the invention discloses a main wiring structure of a transformer substation. The main wiring structure comprises a first bus bar, a second bus bar, a third bus bar, a first buscouplecircuit breaker spacing, a second buscouple circuit breaker spacer, a third buscouple circuit breaker spacer, a first bus voltage transformer spacer, a second bus voltage transformer spacer, a thirdbus voltage transformer spacer, a first bus grounding knife switch, a second bus grounding knife switch, a third bus grounding knife switch, a first bus lightning arrester, a second bus lightning arrester, a third bus lightning arrester, a first incoming line main transformer spacer, a second incoming line main transformer spacer, a third incoming line main transformer spacer and a plurality of outgoing line spacers. The main wiring structure of the transformer substation provided by the embodiment of the invention is an incomplete three-bus structure transformer substation main wiring mode, so that the fault power failure range is small, the processing mode is simple, the reliability is high, the expansion is easy, the grid structure is clear, and the operation mode is flexible.

Description

technical field [0001] The invention relates to the technical field of power grid planning in the electric power industry, in particular to a main wiring structure of a substation Background technique [0002] The electrical main wiring of power plants and substations refers to electrical equipment such as generators, transformers, circuit breakers, isolating switches, transformers, busbars and cables, which are connected in a certain order to represent circuits that produce, collect and distribute electrical energy. Electrical main wiring, also known as primary wiring or electrical main system, represents the main structure of the electrical part of power plants and substations, directly affects the layout of substation devices, relay protection devices, automatic devices and the selection of control methods. Reliability, flexibility and economy play a decisive role. [0003] At present, most substations with a voltage level of 330kV and above adopt the three-half connecti...
