Description

Substation outdoor terminal box solar cooling device

technical field

The utility model relates to an additional facility of an intelligent substation, in particular to a solar cooling device for an outdoor terminal box of a substation.

Background technique

With the popularization and promotion of smart substations, electronic transformers and smart switches have begun to be used on a large scale. The original outdoor terminal boxes of substations are generally used as a transition for the wiring of secondary cables. In the smart substation, the outdoor terminal box is not only used as a transition point for secondary cables and optical fibers, but also equipped with electronic smart devices such as merging units and smart operation terminals. The harsh outdoor operating environment, especially the outdoor high temperature environment, has a greater impact on electronic products. Although the design requirements of electronic equipment such as merging units and intelligent operation terminals comply with national standards, the outdoor high temperature environment will still have a great impact on these electronic products, especially these electronic products themselves contain components that generate heat, such as power supplies and lasers. When the outdoor environment is at high temperature and these outdoor electronic products themselves generate heat, the higher temperature will cause the components of electronic products to age and reduce the service life of electronic products.
