[0035] In order to enable those skilled in the art to better understand the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0036] Reference Figure 1 , is a schematic diagram of the steps of a low-energy consumption non-metallic prefabricated cabin-type enclosure structure optimization method provided by an embodiment of the present invention.

[0037] S11. Obtain properties of prefabricated components of the non-metallic prefabricated cabin, and determine a comprehensive heat transfer coefficient range and a solar radiation coefficient range of the non-metallic prefabricated cabin based on the properties of the prefabricated components.

[0038] At present, there are two types of prefabricated cabin enclosure structures: metal and non-metal. Metal prefabricated cabins have defects such as poor corrosion resistance, brittle fracture at low temperatures, and fast heat transfer at high temperatures. Non-metal prefabricated cabins can overcome the above defects of metal prefabricated cabins. There are currently two main forms of non-metal prefabricated cabins: one is to use non-metallic materials as the external enclosure structure of the cabin, and the other is to directly use high-performance fiber composite materials as the cabin structure, where non-metallic materials include but are not limited to glass fiber or basalt fiber. Therefore, it is first necessary to obtain the prefabricated properties of the non-metallic prefabricated cabin, that is, the selection of non-metallic materials, whether it is glass fiber, basalt fiber or other non-metallic materials. The comprehensive heat transfer coefficient and solar radiation coefficient of the prefabricated cabin formed by different non-metallic materials are different.

[0039] In this embodiment, basalt fiber composite materials are taken as an example. The cabin and cabin roof of the substation prefabricated cabin are all made of basalt fiber composite prefabricated parts. This is a fiber composite prefabricated product that uses basalt fiber as a modified concrete admixture, low-alkali fast-hardening sulphoaluminate cement as a cementitious material, and a variety of aggregates such as polymer materials, sand, and compounds are mixed and stirred in a specific proportion, and then high-pressure sprayed and poured in a mold made of channel steel and steel bars. After standing for 24 hours, the product has a high-performance fiber, polymer material and metal steel performance advantages. The non-metallic prefabricated cabin with the prefabricated part as the prefabricated cabin enclosure structure has good physical properties such as high combustion performance level, long fire resistance, strong corrosion resistance, and good thermal insulation performance.

[0040] After determining the properties of the prefabricated parts, the comprehensive heat transfer coefficient range and solar radiation coefficient range of the substation prefabricated cabin made of basalt fiber composite materials are obtained accordingly. In this embodiment, the comprehensive heat transfer coefficient range is controlled between 0.5 and 5 W / (㎡·k), and the solar radiation coefficient range is controlled to about 0.1 W / (㎡·k).

[0041] S12. Obtain the thermal characteristics of the non-metallic prefabricated cabin, and perform comprehensive heat transfer coefficient matching and solar radiation coefficient matching of the non-metallic prefabricated cabin enclosure structure based on the thermal characteristics, comprehensive heat transfer coefficient range and solar radiation coefficient range.

[0042] Furthermore, based on the properties of the prefabricated parts, the heat source power density level of the non-metallic prefabricated cabin is determined, and according to the heat source power density level, the heat transfer performance and heat transfer direction of the enclosure structure of the non-metallic prefabricated cabin are determined.

[0043] Furthermore, based on the heat transfer performance and heat transfer direction of the non-metallic prefabricated cabin enclosure structure, numerical matching of the comprehensive heat transfer coefficient interval and numerical matching of the solar radiation coefficient interval of the non-metallic prefabricated cabin enclosure structure are carried out.

[0044] There are a large number of power equipment in the prefabricated cabin substation. Its thermal characteristics are different from those of public buildings and civil buildings, which mainly require thermal insulation. It is necessary to treat the non-functional modular prefabricated cabins differently, especially when studying the impact of the heat transfer performance of the prefabricated cabin enclosure structure on the energy consumption of the prefabricated cabin. The different levels of heat source power density in the prefabricated cabin and the resulting thermal characteristics such as heat transfer direction and environmental control set temperature should be fully considered.

[0045] For prefabricated cabins with lower power density levels, such as 110kV GIS combined electrical prefabricated cabin, capacitor complete set prefabricated cabin, and grounding transformer arc suppression coil prefabricated cabin, the heat transfer of the enclosure structure is mainly heat gain, and the heat transfer direction is from outside the cabin to inside the cabin. Good thermal insulation performance can reduce the heat exchange between the outside and inside the cabin. The energy-saving effect increases with the decrease of the comprehensive heat transfer coefficient of the enclosure structure and the decrease of the set temperature of the cabin environment control. Therefore, the comprehensive heat transfer coefficient of the enclosure structure of the prefabricated parts should be considered to be a low value, and the comprehensive heat transfer coefficient range is 0.5~5W / (㎡·k). The comprehensive heat transfer coefficient of the enclosure structure of the prefabricated cabin should be controlled at about 0.5W / (㎡·k) as much as possible.

[0046] For prefabricated cabins with higher power density levels, such as the secondary combination equipment prefabricated cabin and the 10kV switchgear prefabricated cabin, the heat transfer of the enclosure structure is mainly heat dissipation, and the heat transfer direction is from the inside of the cabin to the outside of the cabin. The thermal insulation structure will hinder the transfer of heat from the inside of the cabin to the outside of the cabin. Its energy-saving effect increases with the increase of the heat transfer coefficient of the enclosure structure and the increase of the set temperature of the cabin environment control. Therefore, the comprehensive heat transfer coefficient of the prefabricated enclosure structure should be considered to be a high value. The comprehensive heat transfer coefficient range is 0.5~5W / (㎡·k). The comprehensive heat transfer coefficient of the prefabricated cabin enclosure structure should be controlled at around 5W / (㎡·k) as much as possible.

[0047] It should be noted that, usually, the roof of the prefabricated cabin is greatly affected by solar radiation. Therefore, the roof condition of the prefabricated cabin is used as the condition of the overall prefabricated cabin affected by solar radiation to perform numerical matching of the solar radiation coefficient range. Although the roof of the prefabricated cabin also uses basalt fiber composite prefabricated parts consistent with the cabin body as the enclosure structure, the roof becomes a key part of the energy-saving design due to its large area and long time of direct solar radiation. Therefore, the solar radiation absorption coefficient of the enclosure structure of the roof of the prefabricated cabin is optimized. The lower the solar radiation absorption coefficient, the less the roof is affected by solar radiation heat, and the more obvious the energy-saving effect of the prefabricated cabin. The solar radiation range is , then the solar radiation coefficient of the enclosure structure of the prefabricated cabin is controlled at about 0.1W / (㎡·k) as much as possible.

[0048] S13. Based on the comprehensive heat transfer coefficient matching results and the solar radiation coefficient matching results, the non-metallic prefabricated cabin-type enclosure structure is optimized.

[0049] After determining the matching values ​​of the comprehensive heat transfer coefficient and the solar radiation coefficient, the non-metallic prefabricated cabin-type enclosure structure is optimized based on the matching values, so that the comprehensive heat transfer coefficient and the solar radiation coefficient of the optimized prefabricated cabin-type enclosure structure can be controlled around the matching values.

[0050] Furthermore, the non-metallic prefabricated cabin-type enclosure structure can be disassembled into three parts, the first enclosure structure, the second enclosure structure and the third enclosure structure, wherein the first enclosure structure is the prefabricated cabin body, the second enclosure structure is the prefabricated cabin bottom, and the third enclosure structure is the prefabricated cabin top. The three-part enclosure structure forms a barrier between the space inside and outside the isolation cabin. The first enclosure structure and the second enclosure structure are mainly affected by the comprehensive heat transfer coefficient, and the third enclosure structure is mainly affected by the solar radiation coefficient.

[0051] Furthermore, for the optimization of the prefabricated cabin body as the first enclosure structure, taking the basalt fiber of this embodiment as an example of the prefabricated property, the basalt fiber layer structure is a stacked basalt fiber composite layer, a rock wool insulation layer, a basalt fiber composite layer, and a decorative layer, and then combined with basalt fiber mesh cloth, reinforcement ribs, steel trusses, installation connection points and lifting rings to form a prefabricated cabin basalt fiber composite prefabricated part. Based on the prefabricated property, the prefabricated layer structure is analyzed, and then based on the matching result of the layer structure and the comprehensive heat transfer coefficient, the thickness of each layer of the prefabricated layer structure is optimized and adjusted.

[0052] Furthermore, for the optimization of the prefabricated cabin bottom as the second enclosure structure, since there is a concrete foundation cable trench under the prefabricated cabin bottom, the air convection speed is low, and there is no solar radiation on the cabin bottom in both winter and summer, so the cabin bottom is mainly thermally insulated, and the structure uses a steel plate of preset thickness, with a steel bracket and an air interlayer in the middle, and a ceramic anti-static bottom plate laid on it. In addition, the prefabricated cabin bottom can also be treated with an overall moisture-proof sealing treatment by using a spray foaming polyurethane process to prevent moisture from entering the cabin through the gaps in the cabin bottom.

[0053] Furthermore, for the optimization of the prefabricated cabin roof as the third enclosure structure, although the prefabricated cabin roof also uses the same basalt fiber composite prefabricated parts as the cabin body as the enclosure structure, the cabin roof is a key part of the energy-saving design due to its large area and long time of direct solar radiation. Therefore, the solar radiation absorption coefficient of the cabin roof enclosure structure of the prefabricated cabin is optimized. The lower the solar radiation absorption coefficient, the less the cabin roof is affected by solar radiation heat, and the more obvious the energy-saving effect of the prefabricated cabin. By applying high-reflectivity thermal insulation roof coating on the sunny side of the cabin roof, the solar radiation absorption coefficient of the prefabricated part can be controlled to about 0.1W / (㎡·k).

[0054] It should be noted that for the optimization of the prefabricated cabin roof, a double-slope roof structure can also be used, with a cabin roof slope of not less than 5% to prevent water and snow accumulation, forming a good thermal insulation layer, which helps to maintain a stable temperature in the cabin and reduce the energy consumption of air conditioning and ventilation systems.

[0055] This embodiment provides a low-energy non-metallic prefabricated cabin enclosure optimization method and system, by obtaining the prefabricated properties of the non-metallic prefabricated cabin, and based on the prefabricated properties, determining the comprehensive heat transfer coefficient interval and solar radiation coefficient interval of the non-metallic prefabricated cabin; obtaining the thermal characteristics of the non-metallic prefabricated cabin, and based on the thermal characteristics, the comprehensive heat transfer coefficient interval and the solar radiation coefficient interval, performing comprehensive heat transfer coefficient matching and solar radiation coefficient matching of the non-metallic prefabricated cabin enclosure; based on the comprehensive heat transfer coefficient matching results and the solar radiation coefficient matching results, optimizing the non-metallic prefabricated cabin enclosure. Fully consider the comprehensive heat transfer and solar radiation of the non-metallic prefabricated cabin enclosure structure, effectively control the direction and speed of heat transfer in the material, make the prefabricated cabin fully dissipate heat or insulate, reduce the workload of environmental control equipment such as air conditioners and fans, form a reasonable cabin microclimate, and use the cabin environment of the prefabricated cabin to further reduce the energy consumption of environmental control equipment, so as to achieve the best low power consumption and energy saving effect.
