Embodiment Construction

[0030] Below in conjunction with the accompanying drawings, the present invention will be described in the form of embodiments to assist those skilled in the art to understand and implement the present invention. Unless otherwise specified, the following embodiments and technical terms therein should not be understood without departing from the background of technical knowledge in the technical field.

[0031] In the electrical main wiring, the difference between the single-bus type main wiring and the double-bus type main wiring is:

[0032] The single-bus type main wiring has only one set of bus bars, and all power and outgoing lines are connected to the bus bar through circuit breakers and isolating switches. The transmission power of each outgoing circuit is not necessarily equal, but the load should be distributed evenly on the busbar as much as possible to reduce the transmission of power on the busbar. There are three types of single-bus main wiring: single-bus wiring,...

Abstract

A special-shaped HGIS device, the arrangement direction of multiple first bus outlets and the arrangement direction of multiple second bus outlets are perpendicular to the arrangement direction of multiple main transformer inlets, and the first bus outlet and the second bus outlet are both It is arranged on the same side of the arrangement direction of multiple main transformer inlets. An electrical main wiring, including a busbar group configured as a single busbar connection, a main transformer incoming line and an outgoing line circuit, the busbar group includes at least two busbars arranged side by side and a bus tie line for connecting the two busbars, at least one of the The above-mentioned busbar is a segmented busbar, and one of the incoming lines of the main transformer is respectively connected to two adjacent busbar sections of the segmented busbar through two sets of isolating switches arranged in parallel. Its continuity index and adequacy index are very close to double-bus wiring, and its reliability is consistent with double-bus wiring. A substation using the above-mentioned electrical main wiring, the electrical equipment of the electrical main wiring is respectively arranged on both sides of the busbar group. It has a small footprint and is easy to arrange.

Description

technical field [0001] The invention relates to the technical field of HGIS equipment, in particular to a special-shaped HGIS equipment. [0002] The invention relates to the technical field of electrical main wiring, in particular to an electrical main wiring. [0003] The invention also relates to the technical field of substation structures, in particular to a substation. Background technique [0004] Electrical main wiring is also called primary wiring. The main electrical wiring used in power plants and substations represents the main structure of the power plant or substation, plays the role of collecting and distributing electric energy, and is an important part of the network structure of the power system. The existing main wiring can be divided into two categories: converging busbars and non-converging busbars. Among them, the converging busbars are divided into single busbar unsegmented, single busbar segmented, single busbar segmented with bypass, double busbar ...
