Cable connecting cabinet for photovoltaic power generation system

Abstract

The invention relates to a cable connecting cabinet for a photovoltaic power generation system. The cable connecting cabinet for the photovoltaic power generation system comprises a cabinet body, an insulated supporting column arranged in the cabinet body and a connecting busbar arranged at the end of the insulated supporting column, the connecting busbar is provided with a first connecting end used for being connected with a cable inlet side line of fault photovoltaic box change and a second connecting end used for connecting a cable inlet side line of normal photovoltaic box change, and a cable passing hole allowing a cable to pass through is formed in the cabinet body. After one photovoltaic box in the photovoltaic power generation system goes wrong, the cable connecting cabinet is installed at the cable inlet side of the fault photovoltaic box change, the first connecting end of the connecting busbar is connected to the cable inlet side line of the fault photovoltaic box through acable, the second connecting end is connected to the cable inlet side line of the normal photovoltaic box change through the cable, it is guaranteed that electric energy of the line where the fault photovoltaic box change is located can still be output, the phenomenon that the photovoltaic box change fault greatly affects the power generation efficiency is avoided, and the power supply efficiencyis guaranteed.

Description

technical field [0001] The invention relates to a cable connection cabinet used in a photovoltaic power generation system. Background technique [0002] No matter from the perspective of the world or China, conventional energy is very limited. China's primary energy reserves are far below the world's average level, only about 10% of the world's total reserves. Solar energy is an inexhaustible renewable energy source for human beings. It has the advantages of sufficient cleanliness, relative universality, adequacy of resources, and potential economy. It plays an important role in long-term energy strategies. China's solar photovoltaic power generation has great potential for development. With active and stable policy support, China's solar photovoltaic power generation has ushered in a new round of rapid growth and attracted more strategic investors to integrate into this industry. [0003] With the rise of large-scale photovoltaic grid-connected power generation systems in ...
