A photovoltaic junction box with a detection hole

Abstract

A photovoltaic junction box with detection holes, relating to the technical field of photovoltaic accessories, comprising a box body and a box cover fastened to the box body, the box body is provided with a terminal block inside, and the terminal block is connected with a diode. The side wall of the box body is provided with two cable holes, and a cable is passed through each cable hole, and each cable is electrically connected with the terminal block. Wherein, the terminal block is fixedly connected with two detection shrapnels, and each detection shrapnel is correspondingly connected with a cable in a cable hole; the box cover is provided with two detection holes, and the two detection holes are connected with the two detection holes. The shrapnel corresponds to the setting. The photovoltaic junction box of the present invention does not need to be disassembled for detection, is safe in detection, and saves time and effort.

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...

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.
