Abstract

The invention discloses a novel intelligent junction box which comprises a box body (1) and a box cover (2) and is characterized in that a printed circuit board (PCB) (3) with an intelligent chip is arranged in the box cover (2), an input / output lead (31) of the PCB can be connected with a card interface (4) on the box body, the card interface (4) is connected to a bus bar (5), the box body (1) and the box cover (2) are detachably connected, and a sealing structure (6) is arranged between the box body (1) and the box cover (2) and can be used for internal water sealing of the junction box. By the novel intelligent junction box, the technical problems of slow cooling of the intelligent junction box, high working temperature inside the chip and difficulty in replacing the PCB after damage in the prior art are solved. The novel intelligent junction box has the advantages of favorable cooling performance and high reliability and is easy to maintain and replace.

Description

technical field [0001] The invention relates to a junction box, in particular to a novel intelligent junction box. Background technique [0002] As a low-carbon renewable energy source, the solar energy industry is booming around the world, and the installations in various countries are increasing year by year. In the cutting-edge technology of photovoltaics, smart components are a product that integrates intelligent control into the photovoltaic industry. Existing smart components generally realize their functions by adding smart junction boxes with smart chip circuits to ordinary components. . A common problem of existing intelligent junction boxes is that the operating temperature of the intelligent chip is high, and it is easy to be damaged or even burn and explode due to severe heat in daily work and reliability tests. This has become a bottleneck restricting the development of intelligent components. At the same time, the non-removable smart chip in the existing smar...
