I. Requirements Analysis

Urban and rural development is advancing rapidly, with electricity demand growing steadily across regions. As the power industry continues to expand, high-voltage line anti-tamper warning devices can be installed directly on overhead transmission conductors without power interruption. These serve as hazard indicators for high-voltage lines. When detecting approaching objects, the device emits an audible alert: "High Voltage Danger, Do Not Approach" when objects approach, enabling pedestrians and vehicles to detect and avoid hazards promptly. This prevents high-voltage accidents caused by operational errors from aerial work vehicles like cranes and tower cranes.

II. Working Principle

The high-voltage electric shock prevention warning system is powered by a combination of line-tapped electricity and a lithium battery. It operates when the line current reaches or exceeds 5A. When pedestrians, vehicles, or other objects enter the designated area, the infrared sensor module triggers an immediate response upon detection. This action simultaneously activates the voice module for audio alerts and triggers intense strobe lighting. Users can also configure fixed time intervals for automatic activation of the warning siren and strobe light.

III. Features and Functions

1. Utilizes online induction power capture combined with lithium battery power supply, providing 24/7 warning functionality regardless of day or night.

2. Dual warning function: voice alarm + intense strobe light;

3. Can be installed or removed while energized; lightweight and portable.
