Abstract
The utility model relates to a cable protection type photovoltaic system, which comprises vertical columns on two sides and further comprises two support beams, wherein the top ends of the vertical columns are connected with purlins inclined on the vertical columns through connecting pieces, and the support beams are fixedly arranged on the purlins through fixing bolts and nut blocks. A photovoltaic assembly is fixed on the support beams through press blocks, and connecting cables are placed in wire ducts arranged in each support beam. The connecting cables comprise a PV-1*4 photovoltaic cable, a YJV-2*16 direct-current cable and a YJV-2*25 direct-current cable. The bottom of each support beam is provided with an operating hole sliding plate, and the front end and the rear end of each support beam are respectively provided with a sealing end cover. The cable protection type photovoltaic system has the advantages of being capable of protecting wires and cables arranged externally originally to some extent, and prolong service lives of the wires and the cables.
Description
Technical field
The utility model relates to a kind of photovoltaic system, relates in particular to the rack beam in this photovoltaic system.
Background technology
Photovoltaic bracket of the prior art all is to be main purpose to support photovoltaic module; The useful life of a photovoltaic system is generally about 25 years; Along with the progress of smithcraft and the lifting of surface treatment ability, the useful life of photovoltaic bracket is near photovoltaic system.But because photovoltaic system is installed on the open air more, the assembly cable is in the adverse circumstances for a long time, and rubber cover will be damaged in several years, caused system normally to move.
Summary of the invention
The utility model technical issues that need to address have provided a kind of cable protection type photovoltaic system, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
The utility model comprises: the column of both sides; Link to each other with wingceltis bar on being tilted in column through connector on the top of described column; Also comprise: two rack beams; Described rack beam through set bolt and nut block fixed in position on the wingceltis bar; Photovoltaic module is fixed on the rack beam through briquetting; Wire casing in described every rack beam is placed stube cable; Said stube cable comprises: PV-1 * 4 photovoltaic cables, YJV-2 * 16 direct current cabless, YJV-2 * 25 direct current cabless; Be provided with the handle hole slide plate in the bottom of described rack beam; Forward and backward two ends at described rack beam also are provided with closed end cap respectively.
Compared with prior art, the beneficial effect of the utility model is: can make original external electric wire obtain certain protection, thereby prolong its useful life.
