High-power photovoltaic combined cabinet body

Abstract

The invention relates to a high-power photovoltaic combined cabinet body. The high-power photovoltaic combined cabinet body consists of an alternating-current incoming wire cabinet, a left inversion cabinet and a right inversion cabinet, cabinet bodies of the three electrical cabinets are fixedly mounted together side by side to form an integral cabinet body frame, and the incoming wire cabinet is positioned on the rightmost side; the interior of the cabinet body of the incoming wire cabinet is integrally divided into a front space and a rear space, (namely the front part and the rear part), from top to bottom by utilizing a middle standing pillar; plates are respectively mounted at the front part and the rear part of the cabinet body to enable the front part and the rear part of the cabinet body to be used as independent modules, a circuit breaker and an incoming wire busbar are mounted on the upper mounting plate and the lower mounting plate of the front half part, and a magnetic ring is mounted at the upper part of the rear half part. The high-power photovoltaic combined cabinet body consists of the two inversion cabinets and one alternating-current incoming wire cabinet; after the three cabinet bodies are combined, the current trend is connected by using the busbar, so that the integral structure is compact, and the internal spatial arrangement is reasonable; compared with traditional inversion cabinets and incoming wire cabinet, one incoming cabinet is reduced compared with the conventional inversion cabinet and incoming cabinet combined cabinet body, so that the cost is greatly reduced, the weight of integral equipment is also reduced, and the high-power photovoltaic combined cabinet body is convenient to transport.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation, and relates to a high-power AC cabinet, in particular to a high-power photovoltaic combined cabinet. Background technique [0002] In the field of new energy power generation technology, the existing high-power converter cabinets are often composed of inverter cabinets and incoming line cabinets to form a high-power conversion output and input equipment cabinet structure. When higher power conversion equipment is needed, only the cabinets need to be combined It can be superimposed, and the high-power current converter is generally made into a cabinet structure to facilitate overall transportation and installation. At present, the general high-power current conversion cabinet structure has the following problems: 1. The size of the cabinet is huge, the installation and use places are very limited, and it is inconvenient to transport; 2. The cabinet is generally composed of an i...

AI Technical Summary

Problems solved by technology

At present, the general high-power current conversion cabinet structure has the following problems: 1. The size of the cabinet is huge, the installation and use places are very limited, and it is inconvenient to transport; 2. The cabinet is generally composed of an inverter cabinet and a line cabinet , when more powerful equipment is needed, the above two cabinets are superimposed, resulting in a large number of cabinets, bulky equipment, inconvenient transportation, and a large floor area; 3. The layout of the electrical components inside the cabinet is unreasonable, and the internal The layout cannot fully utilize the space of structural parts, resulting in a waste of structural parts materials, which also results in a large cabinet size and increased costs; 4. The busbar wiring inside the cabinet is unreasonable, and the busbar wiring routes are cumbersome, resulting in a large number of busbars. Too much, the cost will increase greatly, and the weight of the cabinet will also increase; and the number of busbars is too large, and there are many lap joints, resulting in excessive heat dissipation, which is not conducive to the heat dissipation inside the cabinet

Therefore, the existing cabinet body has problems such as large equipment cost waste, bulky size, unreasonable structure, inconvenient installation and transportation, etc.
