Problems solved by technology

The conventional layout method is to lead the single-phase platform equipment on the steel platform on each floor to the ground lead line of the concealed ground grid on the ground through the ground flat copper on both sides of the steel pillar of the equipment. When the number of equipment on the steel platform is large, the conventional layout method The large quantity and weight of the ground flat copper used will increase the load of the steel platform, and the layout of the ground wire is complicated. The connection of the ground wire layout is huge, the installation period is long, and the construction operation is difficult.

Embodiment 1

[0031] see Figure 1-5 , a grounding system for high-voltage electrical equipment on a multi-layer steel structure platform, which includes a grounding ring network flat copper 1 arranged on each steel platform 11; the grounding ring network flat copper 1 of each layer passes through the first silver-copper solder joint 10 respectively Connected with the corresponding grounding down-conductor flat copper 2 by welding or bolts, each of the grounding down-conductor flat copper 2 is respectively led to the underground grounding grid 13 along the steel platform column 12, and the steel platform column 12 The bottom is connected to the underground grounding grid 13 through the steel platform leg grounding downlead 9; the outdoor lightning arrester steel pillar 6 connected on the steel platform 11 is connected with the outdoor lightning arrester steel pillar grounding lead wire flat copper 5, and the outdoor lightning arrester The flat copper 5 of the steel pillar grounding lead-out...

Embodiment 2

[0036] The laying method of the grounding system is as follows:

[0037] The single-phase platform equipment and its steel pillar grounding flat copper on each floor are first led to the grounding ring network flat copper 1 of this layer, and each grounding ring network flat copper 1 is led down to the ground underground concealed grounding network along the steel platform legs 13. The laying method comprises the following steps:

[0038] Step 1: On each steel platform, use grounding flat copper to arrange a rectangular grounding ring network along the length and width of the platform to form a grounding ring network flat copper 1. Copper 1 is suspended and fixed on the lower surface of the platform steel grid with a clamp to make the upper surface of the platform simple and beautiful, and the ground flat copper can also be directly arranged on the upper surface of the platform steel grid;

[0039] Step 2: lead out the ground flat copper to the steel pillar on both sides of t...

Abstract

The invention provides a high-voltage electrical device grounding system on a multi-layer steel structure platform and an arrangement method, wherein the system comprises grounding ring network flat copper disposed on each layer of steel platform, each layer of grounding ring network flat copper is connected with a corresponding grounding downlead flat copper through a first silver-copper weldingspot in a welding or bolted manner, each grounding downlead flat copper is led to a steel platform supporting leg grounding downlead along a steel platform stand column, and the steel platform supporting leg grounding downleads are connected with an underground concealed grounding network. According to the invention, the material consumption, the installation work amount and the construction operation difficulty of the high-voltage electrical device grounding system on the multi-layer steel structure platform can be reduced, the construction period is shortened, the load of the steel structureplatform is reduced, the operation safety and the quality risk are reduced, and the grounding wire arrangement is concise and beautiful.

Description

technical field [0001] The invention relates to a method for arranging the grounding system of high-voltage electrical equipment on a multi-layer steel structure platform of two or more layers in a power transmission and transformation project, and in particular to simultaneously installing outdoor equipment and GIS on a multi-layer steel structure platform Arrangement methods for complex grounding systems of equipment. Background technique [0002] Steel structure platform (hereinafter referred to as "steel platform") is widely used in power engineering due to its advantages of stable structure, quick installation, good adaptability to surrounding buildings and small footprint. With the increase in the types and quantities of high-voltage electrical equipment installed on the steel platform, and industry regulations require that "main equipment and equipment structures should have two grounding down-conductors connected to different main lines of the main grounding grid, an...
