Description

Technical Field

[0001] This utility model relates to the field of hub technology, and in particular to a substation grounding wire hub device. Background Technology

[0002] In the daily operation and maintenance of substations, grounding wires are a key protective component for ensuring the safety of personnel and equipment. Their storage and management directly affect work efficiency and operational safety. Currently, traditional H-type hubs are commonly used in substations to store and organize multiple grounding wires. These hubs mainly consist of two parallel horizontal bars and one vertical connecting bar, forming an "H"-shaped frame structure. Operators need to manually wind the grounding wires around the horizontal bars to complete the hub operation. However, traditional H-type hubs have significant drawbacks in practical applications, making it difficult to meet the efficient and safe operational requirements of substations. Firstly, because the horizontal pole is a single, straight structure, the grounding wire remains at the same height during winding, lacking an effective layered constraint structure. This design causes multiple wires to easily squeeze and intertwine during winding, resulting in not only an inability to form a neat hub shape but also significant scattering. Especially during subsequent movement or retrieval, loose wires easily detach from the horizontal pole, requiring reorganization, wasting considerable time, and potentially causing wear on the terminals due to dragging, affecting the insulation performance and lifespan of the grounding wire, and even posing safety hazards to substation operations. On the other hand, traditional H-type hubs are typically fixed structures, lacking dedicated moving and easy-to-handle components. In substation operations, operators often need to frequently move the hubs behind them to adjust to changes in maintenance locations. Because existing hubs lack a structure for easy gripping or carrying, operators can only move them by lifting the bottom or grabbing the horizontal bars. This is not only laborious but also prone to slipping, causing the hub to tilt and further exacerbating the problem of wires falling off. Furthermore, hubs with numerous grounding wires are quite heavy; relying solely on manual handling is not only inefficient but can also increase the operator's workload, prolong preparation time, and severely impact the overall efficiency of critical substation maintenance and other operations.
