Description

Technical Field

[0001] This utility model relates to the field of substation technology, and in particular to a multi-level fall protection device for high-altitude operations on steel structures in substations. Background Technology

[0002] Substations are crucial facilities in power systems, undertaking core functions such as voltage transformation, power distribution, and transmission control. Through transformers, substations convert the high-voltage electricity output from power plants into voltage levels suitable for users, meeting the electricity needs of different users. At the same time, they utilize switching equipment to flexibly distribute and precisely control electrical energy, ensuring the stability and reliability of power supply. Substations are also equipped with comprehensive protection and monitoring devices that can monitor equipment operating status in real time, promptly detect and handle faults, and ensure power grid safety.

[0003] Safety inspections of substations require high-altitude operations. The protective devices used include the slide rail body and the fall arrestor. In actual installation, the two slide rails are connected with bolts, and the fall arrestor is slidably connected to the slide rails via a movable connector. However, the current slide rail connection has a significant defect: the lack of a positioning and limiting structure. This deficiency has many adverse effects. On the one hand, during assembly, the lack of precise positioning increases the difficulty of operation for workers, resulting in a significant reduction in the slide rail assembly speed. On the other hand, without a limiting structure, the stability of the slide rail connection deteriorates, posing a risk of loosening and creating a safety hazard for high-altitude operations.

[0004] Therefore, in response to the above problems, a new multi-level fall protection device for high-altitude operations on steel structures in substations is proposed. Utility Model Content
