Abstract
Description
Technical Field

[0002] As a safety device in power generation, grounding wire devices are typically simple in structure, low in cost, and easy to operate. They are now widely used during power equipment maintenance operations, effectively protecting maintenance equipment or high-voltage lines and preventing injuries to maintenance personnel from unexpected calls. During high-voltage overhead lines maintenance, grounding wires must be suspended from the drain lines of the line gates within each substation. In practice, these drain lines within substations are typically located at a higher position to ensure a safe distance. To suspend the grounding wire, maintenance personnel must use an insulated operating rod to raise the grounding wire device to the elevated drain line, then slowly align it with the conductor and attach it. Existing grounding wire devices often use a simple locking mechanism with a small opening. This makes it difficult for maintenance personnel to align the grounding wire device with the conductor in bright or dark conditions, as visibility is significantly affected. The device can easily fall, making it difficult for maintenance personnel to remove the grounding wire device. Utility Model Content
