Embodiment Construction

[0013] The substation installation and construction method of the present invention will be described in detail below.

[0014] The steps of the substation installation construction method of the present invention include:

[0015] Dry-type transformer installation:

[0016] (1) During the loading and unloading process of the transformer, unified command and dispatch.

[0017] (2) When using lifting equipment for loading and unloading, the supporting legs of the lifting equipment must be stable and evenly stressed. The lifting ring on the top of the transformer should be used accurately, the hook should be aligned with the center of gravity of the transformer, and the angle between the hanging wire ropes should not exceed 60°. When lifting, it must be tested to prevent the steel cable from damaging the transformer bushing. During the hoisting process, it is strictly forbidden for any person to pass or stay under the boom and hanging objects, and the hoisted equipment must n...

Abstract

A method for installing and constructing a substation in accordance with that present invention, The steps of the method include: Installation of dry-type transformer, primary connection of transformer, Installation of Transformer Accessories, 10kV switch cabinet in place, Fixed installation of cabinet, switch cabinet bus bar installation, equipment commissioning in the switchgear cabinet, low-voltage switchgear in place, Fixed installation of cabinet, Installation of low-voltage switch busbar, commissioning of low-voltage switch equipment, positioning of low-voltage bus bar, installation of low-voltage bus bar, equipment connection, equipment connection, installation of cable tray, support and hanger, assembly and grounding of cable tray, cable laying, commissioning power transmission scheme, adjustment test of electrical equipment, single test of electrical equipment, whole set test, power transmission operation of electrical equipment. The substation installation construction methodregulates every link of the building construction, so that the construction sequence is effectively ensured, the sequence is clear, the process is connected with each other, the cooperation and transition are good, and the good cooperation procedure can be made in the on-site construction process.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for substation installation. Background technique [0002] Generally, a substation is a place where the voltage and current of electric energy are transformed, concentrated and distributed in the power system. In order to ensure the quality of electric energy and the safety of equipment, voltage adjustment, power flow (flow direction and distribution of voltage, current and power in each node and branch in the power system) control and power transmission and distribution lines and distribution are also required in the substation. Protection of major electrical equipment. [0003] A substation is a line connection point in the power network, a facility for transforming voltage, exchanging power, and collecting and distributing electric energy. In the substation, there are power distribution devices of different voltages, power transformers,...
