Problems solved by technology

Since there are many photovoltaic junction boxes in series on the photovoltaic modules, if the photovoltaic modules of a large-scale photovoltaic power station need to be inspected, the workload is huge and the efficiency is extremely low by manually dismantling the optical cables for inspection, which cannot meet the requirements of rapid system maintenance. In the process, there is still a potential safety hazard of electric shock for operators, which brings great trouble to the operation and maintenance of large-scale photovoltaic power plants.

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 with figure 2 As shown, the present invention provides a photovoltaic junction box with a detection hole, which includes a box body 1 and a box cover 2 fastened to the box body 1 . The inside of the box body 1 is provided with a terminal block 3, and the terminal block 3 is connected with a diode 4, which is used to prevent reverse charging from damaging the photovoltaic components on the solar panel and prevent a short circuit of a photovoltaic component from causing the entire photovoltaic component to not available. Two cable holes 5 are opened on the side wall of the box body 1 , and a cable 9 is penetrated into each cable hole 5 , and each cable 9 is electrically connected to the terminal block 3 . Wherein, the terminal block 3 is fixedly connected with two detection elastic pieces 6 , and each detection elasti...

Abstract

The invention provides a photovoltaic junction box with detection holes and relates to the technical field of photovoltaic accessories. The photovoltaic junction box comprises a box body and a box cover buckling the box body. A wire holder is arranged inside the box body and is connected with a diode, two cable holes are formed in the side wall of the box body, and a cable penetrates into each cable hole and is electrically connected with the wire holder. The wire holder is fixedly connected with two detection elastic pieces, each detection piece is correspondingly connected with the cable in each cable hole, the box cover is provided with two detection holes, and the two detection holes are and the two detection elastic pieces are correspondingly arranged. By means of the photovoltaic junction box, detection can be conducted without detaching the cables, detection is safe, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic accessories, in particular to a photovoltaic junction box with a detection hole. Background technique [0002] Converting solar energy into electrical energy can not only save energy, alleviate the shortage of power supply, but also reduce environmental pollution. Therefore, solar photovoltaic technology has attracted more and more attention and favor from the public. Photovoltaic modules composed of multiple solar cell units are widely used. For example, photovoltaic modules are used to build power generation systems, or used as curtain walls of buildings or installed on roofs of buildings. [0003] The photovoltaic junction box is a commonly used accessory in the photovoltaic industry. It is a transition device installed on the solar panel to connect the leads of the photovoltaic modules on the solar panel. In the process of use, it is necessary to regularly maintain and manage the photovo...
