Description

Technical Field

[0001] This utility model relates to the field of outdoor cabinet technology, and in particular to a pole-mounted integrated outdoor cabinet for power grid communication lines. Background Technology

[0002] The outdoor integrated cabinets currently used in power grid communication systems have several shortcomings:

[0003] 1. Structural aspects: Existing equipment generally adopts a large-volume box structure, which has poor adaptability to installation in space-constrained scenarios such as columns and towers, increases infrastructure costs, and seriously restricts the flexibility of construction deployment;

[0004] 2. Outdated fiber optic access technology: Traditional fusion splicing process is time-consuming, costly, and significantly affected by ambient temperature and humidity. Construction quality is difficult to guarantee under adverse weather conditions, resulting in low overall deployment efficiency.

[0005] 3. Safety protection deficiencies: The existing equipment is not equipped with a separate grounding device. In the event of lightning overvoltage or power system failure, the equipment insulation performance is insufficient and it is difficult to meet the requirements for use in harsh environments.

[0006] 4. Insufficient scalability: The existing equipment's fiber optic port configuration usually only meets basic needs, with less than 30% redundancy. This makes it unable to adapt to the growing demand for fiber optic resources brought about by new services such as distributed energy access and distribution automation in smart grid construction, resulting in frequent equipment replacements during later expansions.
