Description

Technical Field

[0001] This utility model relates to the field of anti-static technology for prefabricated substations, specifically to an anti-static device for prefabricated substations. Background Technology

[0002] Prefabricated substations, as key equipment in power systems, are widely used in urban power distribution, industrial and mining enterprises, and various construction sites. They contain a large number of precision electronic components and electrical connection terminals. During operation and maintenance, operators frequently come into contact with these components. The human body easily accumulates thousands of volts of static charge during daily activities. Without effective protective measures, electrostatic discharge can damage electronic circuit boards, control modules, or wiring terminals, affecting normal equipment operation or even causing malfunctions.

[0003] Currently, the industry commonly uses anti-static wrist straps connected to a grounding terminal via wires to release static electricity from the human body. A common connection method is to use alligator clips to hold the strap to the grounding terminal. While this method is simple and easy to implement, it has significant drawbacks: the alligator clips have limited clamping force and are easily pulled off by external forces when the operator moves, causing the anti-static measure to fail and creating a safety hazard.

[0004] Therefore, we propose a prefabricated substation anti-static device. Utility Model Content
