Problems solved by technology

As one of the main equipment of the photovoltaic power station, the combiner box after welding and molding of cold-rolled steel plates can meet the design service life requirements in some relatively dry environments in the west, but it is easy to rust in environments with high ambient humidity or severe corrosive media , such as fishery greenhouses and agricultural greenhouses in coastal areas are extremely susceptible to corrosion by their own humid environment and coastal salt spray. It will shorten the service life of the combiner box, and if it is maintained regularly according to the requirements, it will cost a higher cost of anti-corrosion treatment

Abstract

The invention discloses a fully-insulated combined type photovoltaic combiner box comprising a box body a and a box body b, wherein the box body a and the box body b are rectangular box structures with an opening on one side, a door plate is arranged on the opening side of the box body a and the box body b, movably connected sealing plates are arranged on the box body a and the box body b, installing plates are installed in the box body a and the box body b, sliding blocks are arranged on the upper and lower side arms of the installing plates, and insulating films are attached to the external surfaces of the box body a, the box body b, the sealing plates and door plates. The fully-insulated combined type photovoltaic combiner box employs insulating materials to prevent rusting, reduce the frequency of regular maintenance, and reduces maintenance cost. The use period is long. A combination structure of box body a and a box body b is used, the box bodies can be expanded according to the different numbers of installation lines, and the installation is flexible.

Description

technical field [0001] The invention relates to a fully insulated combined photovoltaic combiner box, which belongs to the technical field of combiner box manufacture. Background technique [0002] The photovoltaic combiner box is an indispensable equipment for photovoltaic power plants. The photovoltaic combiner box connects the output of several string photovoltaic inverters in parallel to the combiner box. After converging in the combiner box, it outputs to the AC low-voltage control cabinet through the AC circuit breaker. [0003] Conventional photovoltaic combiner boxes are formed by welding cold-rolled steel plates and then sprayed with plastic. As one of the main equipment of the photovoltaic power station, the combiner box after welding and molding of cold-rolled steel plates can meet the design service life requirements in some relatively dry environments in the west, but it is easy to rust in environments with high ambient humidity or severe corrosive media , such...
