Description

Technical Field

[0001] This utility model relates to the field of cable branching technology, and specifically to a cable branching box for switchgear. Background Technology

[0002] Cable distribution boxes are crucial equipment in power systems, widely used in urban power distribution networks, industrial enterprises, and power supply and distribution systems of various buildings. Their main function is to branch, connect, and distribute electrical energy from cable lines, rationally allocating the power from the main cable to various branch lines to meet the electricity needs of different users.

[0003] However, traditional cable distribution boxes have revealed many problems during use. The internal space layout of traditional cable distribution boxes lacks forward-looking design and is mostly a fixed structure. The usable space is strictly limited. New components cannot find suitable installation locations and can only be placed externally or installed in corners. This not only affects the overall aesthetics of the box, but also increases the risk of component damage due to external environmental factors, which greatly limits the further expansion of equipment functions.

[0004] Meanwhile, the messy internal cable layout greatly inconveniences line maintenance and troubleshooting; furthermore, due to the lack of effective fixing measures, branch lines are prone to loosening during long-term operation, which may not only cause electrical faults and local power outages, but also damage components due to arcing, seriously affecting the reliability and stability of the power system. Therefore, there is an urgent need to design a cable branch box for switchgear to solve the above problems. Utility Model Content
