A 3-building layout substation

Abstract

The invention belongs to the technical field of transformer substations, and provides a 3-floor-layout transformer substation. The 3-floor-layout transformer substation comprises a power distributiondevice building which is arranged in the middle of a substation site of a transformer substation, wherein a 110 kV GIS power distribution device room is arranged on the north side of the power distribution device building, and a 220 kV GIS power distribution device room is arranged on the south side of the power distribution device building; an alarm transmission room is arranged on the east sideof the power distribution device building; a maintenance patrol center is arranged on the east side of the 110 kV GIS power distribution device room; a fire pool and a water pump room are correspondingly arranged on the east side of the 220 kV GIS power distribution device room and the south side of the alarm transmission room; the west side of the power distribution unit building is provided witha fire fighting lane; and a fire fighting lane is arranged between the east side of the power distribution unit building and the alarm room. According to the abovementioned scheme of the transformersubstation, an outdoor support is arranged on a roof, so that the vertical space is fully utilized, and the occupied area is effectively saved; GIS is changed from outdoor to indoor arrangement, and thus the workload of operation, maintenance and overhaul of GIS equipment in the future is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of substations, in particular to an area-saving three-building layout substation. 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. There are many problems in the implementation process of traditional substations, such as: large equipment volume, large spacing, excessive land occupation, waste of land resources; poor thermal insulation performance of substation enclosure structures, a large number of non-energy-saving equipment, resulting in energy waste.

[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.

There are many problems in the implementation process of traditional substations, such as: large equipment volume, large spacing, excessive land occupation, waste of land resources; poor thermal insulation performance of substation enclosure structures, a large number of non-energy-saving equipment, resulting in energy waste

[0003] In the existing technology, for example, the 220kV indoor GIS substation is designed with two buildings according to the standard, but the 110kV GIS indoor comprehensive power distribution building of this scheme is relatively long and occupies a large area. range unavailable

In addition, the existing standard design has an indoor GIS scheme for one building. The 110kV of this scheme is the cable outlet, which requires the cable to be transferred to the overhead line, which increases investment and makes the implementation of the line more difficult.

In addition, when installing equipment in the prior art, the support area of ​​the bracket structure cannot be adaptively adjusted, and the adaptability to different installation spaces is not strong
