Embodiment Construction

[0021] Those skilled in the art will be more aware of the above and other objects, advantages and features of the present invention according to the following detailed description of specific embodiments of the present invention in conjunction with the accompanying drawings.

[0022] The 230 kV GIS building with optimal structure design includes the main transformer layer, GIS equipment layer 1, and the roof and outlet layer. The beam 3 of the span is low in height, and the floor of the span where the GIS equipment is located is partially filled with lightweight concrete 4, so that the floor height of the filling place is the same as the floor height of the other span, and the cable channel is not filled, resulting in a final floor that is lower than the floor. The cable channel 5 on the surface is used for laying cables.

[0023] Preferably, the girder height of the span where the GIS equipment is located in the GIS equipment layer is 0.4-0.6 meters lower than that of the oth...

Abstract

The invention provides a 230 kilovolt GIS building with an optimized structure design. The GIS building comprises a main transformer layer, a GIS equipment layer and a roof and outgoing line layer, wherein the GIS equipment layer is above the main transformer layer, and a crane is arranged at the top of the GIS equipment layer; the GIS building adopts a double-span design horizontally; and in theGIS equipment layer, the height of a profiled beam of the span where the GIS equipment is located is lower than that of the other span, lightweight concrete is partially filled on the upper part of afloor of the span where the GIS equipment is located, so that the height of the filled floor is the same as the height of the floor of the other span, a part of a cable channel is not filled, and thecable channel which is finally lower than the floor is formed for laying cables. According to the GIS building, the construction difficulty of the GIS building can be reduced, the project investment is saved, and the space utilization rate of the building is improved.

Description

technical field [0001] The invention relates to the technical field of high-voltage power equipment construction, in particular to a 230-kilovolt GIS building. Background technique [0002] SF 6 Gas-insulated metal-enclosed switchgear (GIS) has the advantages of small footprint, small size, light weight, all components are sealed and free from environmental interference, and has excellent breaking performance-the circuit breaker adopts a new arc-extinguishing principle. Self-energy interrupter, and highly reliable operation, less loss, low noise, has been widely used. [0003] In order to ensure the safety of the system, the general GIS system is installed in an independent building. [0004] When installing GIS equipment, it is necessary to connect a large number of cables to the GIS equipment, so it is necessary to set up cable trenches. In the current GIS building design, a cable interlayer is usually built under the GIS floor slab with a height of 1.5-1.8 meters, whic...
