Distribution box for photovoltaic power station

Abstract

The invention discloses a power distribution box for a photovoltaic power station. The power distribution box comprises a box body; the box body is connected with a pair of quick-mounting fastening anti-falling mechanisms; each quick-mounting fastening anti-falling mechanism comprises a pair of pressing fastening anti-falling mechanisms; and a connection protection mechanism is connected between the pair of pressing fastening anti-falling mechanisms. Each pressing fastening anti-disengaging mechanism comprises a connecting piece; a suction cup is connected to the connecting piece; a gas fluidcavity is dug in the connecting piece; a sealing baffle is arranged between the gas fluid cavity and the suction cup; an air outlet cavity is dug in the connecting piece; and a first sealing ball is arranged in the air outlet cavity. According to the power distribution box for the photovoltaic power station of the invention, the power distribution box is provided with the quick-mounting type fastening anti-falling mechanisms, so that a traditional installation mode of the power distribution box is changed, an installer does not need to carry out a series of complex installation processes, theinstallation efficiency of the installer is greatly improved, the working intensity of the installer is greatly reduced; and meanwhile, the wall body is prevented from being damaged, and the problem that the wall body is not attractive due to installation of the power distribution box is avoided.

Description

technical field [0001] The invention belongs to the technical field of distribution boxes, and in particular relates to a distribution box for a photovoltaic power station. Background technique [0002] Household photovoltaic power generation systems are usually composed of photovoltaic modules, inverters, photovoltaic distribution boxes, electric meters, power grids, etc. Although the distribution box does not account for a high proportion of the total system cost, it plays an important role in the photovoltaic power generation system. important role. The distribution box is generally composed of a circuit breaker, a self-resetting overvoltage and undervoltage protector, a surge protector, a backup circuit breaker for the surge protector, and a knife switch. The distribution box has two main functions: one is the electrical isolation function, the distribution box can cut off the electrical connection between the photovoltaic module, the inverter, the distribution cabinet ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a distribution box for a photovoltaic power station to solve the problem that the installation process of the above-mentioned distribution box is relatively complicated, which easily causes physical fatigue of the installer and easily damages the wall during the installation process, which affects the overall aesthetics of the wall. question
