Main Junction Box of Water Solar Power Plant

摘要

The present invention provides a main junction box for an aquatic solar power generation plant, capable of improving generation efficiency and lifespans of components. The junction box includes: a body including a storage chamber for storing components and a radiating chamber for discharging heat from the components to the outside, and opening or closing the storage chamber through a door; a roof installed in the upper part of the body, comprising a hollow part for blocking heat delivered by direct sunlight, and having a slope; and an air breather installed in the hollow part of the roof on the storage chamber, and discharging the heat to the outside by being opened when pressure in the storage chamber is higher than atmospheric pressure. Even if the internal temperature of the storage chamber is increased by a component in the chamber or an external factor of an aquatic environment, the main junction box is able to discharge heat in the storage chamber to the outside depending on each condition, thereby making a quick response possible.
