Junction box used in power trench of solar power generation pavement and installation method

Abstract

The invention provides a junction box used in a power trench of a solar power generation pavement and an installation method. The junction box includes an arc-shaped bottom plate, a top plate, a long-side panel, a short-side panel opposite to the long-side panel, a first side plate and a second side plate. The arc-shaped bottom plate is inwardly tangent to the long-side panel, the short-side panel, the first side plate and the second side plate. The top plate is hermetically connected with the long-side panel, the short-side panel, the first side plate and the second side plate. The first sideplate and the second side plate are provided with through holes. Heat shrinkable sleeves are arranged on the outer edges of the through holes. The installation method of the junction box comprises the steps of junction box fixing, junction box opening, junction box threading, connecting of positive and negative MC4 plugs in series, junction box closing, junction box sealing, and junction box embedding. The junction box used in the power trench of the solar power generation pavement has the advantages of simple structure, convenient use and high practicability. The installation method of the junction box is simple and easy to operate and learn.

Description

technical field [0001] The invention relates to the technical field of solar power generation surfaces, in particular to a junction box and an installation method used in a power groove of a solar power generation surface. Background technique [0002] Solar power generation surface technology is a clean energy technology that countries all over the world are competing to develop. Solar power generation surface technology makes full use of clean solar energy resources, and the vast linear space of roads will be able to realize Metal materials such as photoelectrically converted monocrystalline silicon wafers, polycrystalline silicon wafers, and thin film silicon wafers are paved on the road surface, turning the existing asphalt concrete pavement or cement concrete pavement into a huge solar energy collection platform, and the clean electric energy converted from solar energy is passed through Electrical components and equipment are integrated into the national grid or collec...

AI Technical Summary

Problems solved by technology

Based on the implementation of the comprehensive application test section project of solar power generation surface technology in the expressway and the follow-up observation in the later stage, it was found that the positive and negative MC4 plugs from the photovoltaic module board were directly buried in the road materials filled in the power trench, It is not conducive to later maintenance and maintenance, and it is easy to cause damage to the positive and negative MC4 plugs during power trench filling and maintenance construction

In addition, when it rains, there will be water in the groove, and the rainwater will infiltrate from the connection of the positive and negative MC4 plugs, which will easily cause the positive and negative MC4 plugs to heat up or short circuit, seriously affecting the stability and durability of the positive and negative MC4 plugs. sex

After investigation, there is no special junction box and installation method for solar power generation surface power trenches on the market. Therefore, it is very necessary to design a junction box and installation method for solar power generation surface power trenches. , so, how to design a junction box and installation method for use in the power trench of the solar power generation surface has become a problem we need to solve at present
