BIPV Juction Box of Photovoltaic Module Used for Building Integrated Photovoltaic System

摘要

The junction box of the present invention is to continuously obtain the constant voltage by continuously connecting the DC power generated by the solar module of the building-integrated solar power system in series with other solar modules, and at one end, the DC power generated by the solar module The DC power is drawn in by combining with the incoming bus bar, and the other end is combined with the drawn out bus bar through which DC power is drawn, and DC power is drawn out to the next solar module, and the drawn DC power is drawn in and out in one direction. Wealth; The power in / out unit is installed inside, the in / out bus bar and the in / out bus bar are drawn in and out, and the power in / out unit is composed of a box casing that acts as a waterproof case to be exposed to the outside. Two conducting clip bodies contacting both sides of the bar and the extraction bus bar to receive or withdraw DC power; A conductive upper clip for improving conductivity by pressing the outer surfaces of both sides of the conductive clip body to increase the contact force between the incoming bus bar or the drawn bus bar and the conductive clip body; The current flows only in one direction and does not flow in the reverse direction, and both ends are composed of diodes to which the conductive clip bodies are respectively coupled, and the box casing has the incoming and outgoing bus bars and the outgoing bus bars drawn in and out. A casing body installed therein; It is composed of a casing cover coupled to the upper portion of the casing body in one touch to cover the casing body. According to the clip-type BIPV junction box used in the building-integrated solar module of the present invention, since the power in / out section can be manufactured in advance in the factory, the coupling between the conductive clip body and the diode connection portion cannot occur, and after the bus clip is inserted into the conductive clip body The conductive upper clip can be inserted and pressed, making connection with the busbar easier than ever, high contact force, and inadvertently preventing connection of the busbar due to carelessness. After attaching with silicone and molding with silicone, it is easy to completely waterproof, and it has the advantage of easy maintenance because it is simple structure and easy to separate the busbar.
