Assembled high protection photovoltaic combiner box

Abstract

The invention discloses an assembled high-protection photovoltaic combiner box, which includes a box body, a mounting plate and a door panel. The box body is a rectangular frame structure with openings on both sides. The mounting plate and door panels are respectively installed on both sides of the box body, and sealing corner pads are also included. , rear gussets and front gussets, the four corners of the box are respectively provided with sealing corner pads, and the rear gussets and front gussets are installed in the sealing corner pads; the invention also discloses an assembled high-protection photovoltaic combiner box The installation method; this product adopts the special design and manufacturing process of integrated box body and internal sealing, which completely solves the impact of the harsh external environment on the internal components, and the protection level is as high as IP65; all the parts that make up the box body adopt standard modularization , without any welding, completely reduce the impact of thermal stress caused by welding on its shell, improve efficiency, save energy and reduce consumption.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a photovoltaic combiner box, in particular to an assembled high-protection photovoltaic combiner box and an installation method thereof. Background technique [0002] With the popularity of new energy, low carbon and other concepts, the vigorous development of solar power generation technology, as its upstream equipment - photovoltaic combiner box has been widely used, resulting in a rapid increase in its number. At present, the photovoltaic combiner boxes on the market are all welded. Theoretically speaking, there is nothing wrong with the welding type. From the perspective of the protection level alone, as long as the entire box is fully welded, the corresponding protection level should be achieved, but the actual situation is not the case. There are three reasons for this: [0003] 1. The welding seam is long and the welding workload is heavy. For a 16-way combiner box, th...

[0004] 2. Even if the above welding is barely completed, the ensuing thermal stress and thermal deformation will cause the deformation of the box, the door panel is not tightly sealed, the weld cannot adapt to the test of the harsh environment, and the protection level will drop. It brings a lot of inconvenience in the use and maintenance of

After the product has been transported for a long distance, if the solder joints are desoldered and the surface of the box body is involved in plastic spraying, it cannot be well remedied on site

[0005] 3. The welding operation itself is a special type of work, which is harmful to the human body. For products with a large amount of consumption, too much welding design itself is also a deficiency

If welding is added, another process is artificially added. Too many human factors are not conducive to the stability of product quality. At the same time, the production cost has risen sharply, which is not conducive to market competition.
