500kV GIS equipment indoor arrangement type transformer substation

Abstract

The invention provides a 500kV GIS equipment indoor arrangement type transformer substation. The 500kV GIS equipment indoor arrangement type transformer substation comprises a 500kV power distribution device, a main transformer, a 220kV power distribution device and a 35kV power distribution device, the whole transformer substation is arranged in a parallel three-row mode, 500kV GIS equipment of the transformer substation is arranged indoors, and the GIS equipment is arranged indoors, so that the workload of operation, maintenance and overhaul of the GIS equipment in the future can be greatly reduced, the operation cost is reduced, the reliability of equipment operation is improved, and safe and stable operation of a system is ensured. The 500kV GIS chamber adopts a framed bent structure. The roof adopts the profiled steel sheet composite floor slab, so that the use of a high formwork of a roof beam-slab structure with higher dangerousness can be avoided; a traditional formwork is not needed, and construction period cost is saved; a roof beam adopts the steel beam, the beam section is smaller than the reinforced concrete section, so space can be saved; and meanwhile, the bent frame columns are made of reinforced concrete, the overall rigidity of the structure is improved, the compression resistance of the reinforced concrete structure is fully utilized, and high economical efficiency is achieved.

Description

technical field [0001] The invention belongs to the technical field of substations, and provides an indoor arrangement type substation with 500kV GIS equipment. Background technique [0002] In recent years, with the development of my country's economy, the demand for power supply is increasing, and the construction of substations is increasing. Because some substations did not consider land saving, energy saving, water saving, material saving, and environmental protection in the early stage of construction. Measures have led to a series of problems such as environmental pollution, energy, and resource waste after the completion of the substation. The existing 500kV substation usually adopts outdoor conventional equipment or outdoor HGIS equipment, which covers a large area, and outdoor GIS equipment is also used. In coastal areas with high salt density, it is a seriously polluted area, and affected by natural conditions such as typhoons, the outdoor layout is not suitable. ...

[0002] In recent years, with the development of my country's economy, the demand for power supply is increasing, and the construction of substations is increasing. Because some substations did not consider land saving, energy saving, water saving, material saving, and environmental protection in the early stage of construction. Measures have led to a series of problems such as environmental pollution, energy, and resource waste after the substation is completed.

The existing 500kV substation usually adopts outdoor conventional equipment or outdoor HGIS equipment, which covers a large area, and outdoor GIS equipment is also used. In coastal areas with high salt density, it is a seriously polluted area, and affected by natural conditions such as typhoons, the outdoor layout is not suitable. Conducive to the safe and stable operation of the equipment
