Abstract

The invention discloses a photovoltaic grid-connected system for a box-type substation and an installation method, and the photovoltaic grid-connected system comprises a plurality of division bars, a plurality of photovoltaic panels, a hook-shaped baffle plate, and a grid-connected cabinet. The division bars are installed on the upper surface of the box cover and used for dividing the upper surface of the box cover into a plurality of areas. The photovoltaic panel covers the area and is attached to the corresponding division bar through a structural adhesive; the hook-shaped baffle is arranged at the position, attached to the lower half portion of the photovoltaic panel, of the division bar and used for fixing and supporting the photovoltaic panel. The grid-connected cabinet is installed on the box body, a grid-connected device is installed in the grid-connected cabinet, and the grid-connected device is electrically connected with the output end of the photovoltaic panel and the low-voltage chamber and used for receiving electric energy generated by the photovoltaic panel and outputting the electric energy to the low-voltage chamber after processing. The invention further provides an installation method for installing the photovoltaic grid-connected system on the box-type substation. According to the technical scheme disclosed by the invention, the difficulty of adding the photovoltaic grid-connected system to the box-type substation can be reduced, the adding time consumption is shortened, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of box-type substations, in particular to a photovoltaic grid-connected system and an installation method for box-type substations. Background technique [0002] Box-type substation, as a commonly used substation equipment, has a very large outdoor stock, a large number and a wide distribution range. Using these characteristics of the box-type substation, it is installed with a photovoltaic grid-connected system, which can fit the distributed energy structure. Effectively convert solar energy into electrical energy and integrate it into the grid, so as to meet the requirements of low-carbon and green new energy acquisition. However, in the prior art, it is difficult and time-consuming to install a photovoltaic grid-connected system on the box-type substation, and the cost of directly replacing the box-type substation is relatively high. Contents of the invention [0003] The present invention aims to solv...
