Problems solved by technology

[0003] However, due to the bad weather in the western plateau, the temperature difference between day and night is very large. In the case of a large temperature difference, the traditional grid-connected cabinet has a high failure rate of internal electrical components and a low service life, which cannot meet the current use requirements.

Embodiment 1

[0034] refer to Figure 1-4 In this embodiment, a distributed photovoltaic grid-connected cabinet is proposed, which is characterized in that it includes a sealed cabinet body 100, and a heat conduction component 200 is installed in the cabinet body 100. One end of the heat conduction component 200 is arranged in the cabinet body 100, and the other end Buried in the underground soil, the heat conduction component 200 is used to guide the heat in the cabinet body 100 and exchange the heat in the soil.

[0035] Through the setting of the heat conduction component 200, the heat in the cabinet can form a heat exchange cycle with the underground soil, so that in the northwest plateau area, when the temperature is too high during the day, the heat can be introduced into the underground soil, and when the temperature is too low at night, The heat in the underground soil can be introduced into the cabinet, and the function of balancing the temperature difference without relying on add...

Abstract

The invention relates to a distributed photovoltaic grid-connected cabinet. The cabinet comprises a sealed cabinet, wherein a heat conduction assembly is installed in cabinet, one end of the heat conduction assembly is arranged in the cabinet, the other end is buried in underground soil, and the heat conduction assembly is used to guide heat exchange between the cabinet and the soil. The cabinet is advantaged in that the structure is stable, layout is reasonable, heat exchange circulation with the ground can be realized, a problem of overlarge temperature difference is effectively balanced, use of extra temperature control and temperature regulation equipment is avoided, use cost is reduced, assembly is convenient, transportation is convenient, and current use requirements are met.

Description

technical field [0001] The invention relates to the electrical cabinet field, and specifically relates to a distributed photovoltaic grid-connected cabinet. Background technique [0002] In the western plateau area of ​​my country, photovoltaic resources are abundant. Now my country has built many photovoltaic power stations in the west. After photovoltaic power generation, it needs to be connected to the grid. This requires grid-connected cabinets to be connected to the grid. Since many photovoltaic fields are distributed in different regions, each Photovoltaic fields need matching grid-connected cabinets. [0003] However, due to the bad weather in the western plateau and the large temperature difference between day and night, the traditional grid-connected cabinet has a high failure rate of internal electrical components and a low service life under the condition of large temperature difference, which cannot meet the current use requirements. Contents of the invention ...
