Combined type all-in-one machine for photovoltaic power generation

Abstract

The invention discloses a combined type all-in-one machine for photovoltaic power generation. The combined type all-in-one machine comprises a base and a top cover. An environment ventilation fan, a high-voltage chamber, a transformer chamber, a high-voltage operation chamber, an inverter chamber and a low-voltage cabinet are formed on the base. The high-voltage chamber, the transformer chamber, the high-voltage operation chamber, the inverter chamber and the low-voltage cabinet are designed to be of an integrated structure. A front surrounding plate, a front door panel and a side door panel are arranged in the inverter chamber. A filter screen fixing frame and a shutter are arranged on the front surrounding plate, the front door panel and the side door panel. A filter screen is arranged in the shutter. The shutter is provided with a bent portion capable of blocking sands blown by the wind. According to the invention, the outdoor installation and the outdoor use of the combined type all-in-one machine can be realized. Meanwhile, sands blown by the wind can be effectively blocked. The combined type all-in-one machine is higher in integration level and smaller in appearance size. Thetransportation cost and the material cost of the combined type all-in-one machine are reduced. The combined type all-in-one machine is lighter in weight, more comprehensive in function, stronger in manufacturability, lower in complexity and better in practicability.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation equipment, in particular to a combined integrated machine for photovoltaic power generation. Background technique [0002] my country's photovoltaic power generation industry is developing rapidly. Stimulate more technologies to improve the photovoltaic grid-connected power generation system. In the actual application of large-scale photovoltaic power generation system projects, in order to meet the application in the field outdoor environment, the current three methods are as follows: The communication cabinet is specially built for civil engineering power distribution room, and each unit is arranged in it separately, and the photovoltaic power generation transformer is added to carry out the step-up and hanging network billing operation; the other is that the equipment manufacturer manufactures special non- For civil engineering facilities, the above-mentioned unit equipment is inst...

Problems solved by technology

[0003] Compared with the system, the third type has integrated all functional units into one container equipment, and the management is relatively centralized, but this kind of photovoltaic power generation integrated machine still has some problems such as low internal space utilization, poor system management, and installation and maintenance problems. Inconvenient maintenance, etc., the specific performance is as follows:

[0004] First, the container material equipment is bulky in appearance, and the photovoltaic equipment foundation has a large amount of on-site construction and many materials

[0005] Second, the top cover of the container is a movable structure, and the sealing is insufficient, and the shutters are installed on the corrugated boards. The corrugated boards are processed in a complicated process, and the shutters are processed by gusset plates, which is prone to deformation, poor sealing performance, and insufficient anti-theft performance

[0006] Third, the installation of the filter cotton inside the louver is complicated, there are many bending parts welded inside the door panel, the welding process is complicated, the fixed filter is not strong enough, and it is inconvenient to maintain the surface of the filter. It can be said that the manufacturing is complicated and the maintenance cost is high.

[0007] Fourth, the output AC end of the inverter is connected to the low-voltage bushing of the photovoltaic power generation box by cables. The process is long, the number of cables is large, and the prefabricated cables take a long time. The installation is inconvenient and needs to go through the bottom of the inverter, and the production cycle is lengthened.

[0008] Fifth, the blinds adopt a straight bending structure, which cannot effectively block wind and sand
