Abstract

The invention provides an installation method of a diameter-expanded flexible busbar of a substation. The method comprises the following steps of assembling an insulator string; discharging the diameter-expanded flexible busbar; crimping the diameter-expanded flexible busbar; sequentially installing a fitting and the insulator string in the diameter-expanded flexible busbar of which crimping is completed; and hoisting the diameter-expanded flexible busbar of which installation is completed. According to the installation method of the diameter-expanded flexible busbar of the substation, provided by the invention, a sequence of installing the diameter-expanded flexible busbar is proposed, the guidance of installing the diameter-expanded flexible busbar is achieved, the diameter-expanded flexible busbar can be accurately installed by a constructor, repeated construction is prevented, and the construction efficiency is improved; meanwhile, the construction process level is also improved; and moreover, a guarantee is also provided for normal running of the substation in future.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation, in particular to a method for installing soft busbars with expanded diameter in substations. Background technique [0002] At present, the soft busbars used in the construction of AC UHV substations in my country are heat-resistant aluminum alloy stranded wires with expanded diameters. The installation of expanded diameter soft busbars between frames is an important part of the electrical installation and construction of UHV substations, and its installation quality directly affects The future operation status of the substation. The cross-line construction between the frames includes multiple processes such as the expansion of the flexible busbar, the crimping assembly of the fittings, and the hoisting, and the overall workload is relatively large. At present, there is no uniform guidance for the installation of soft busbars, and it is usually carried out according t...
