The high-voltage sound and light voltage detector produced by TID POWER is a safety tool used to detect whether high-voltage AC lines and equipment have power frequency voltage. It alerts the equipment's live status through dual sound and light alarms. The device adopts epoxy resin insulation rod and ABS injection molded shell, equipped with four 1.5-volt button type alkaline battery power supply systems, with full circuit self-test function and anti-interference characteristics. Widely used in power plants, substations and other power enterprises, the applicable voltage range covers 0.1kV to 500kV.
Precautions
1. Check before use
1.1. Self check function: Before use, a self check must be performed to ensure that the voltage tester is functioning properly (such as indicator lights and buzzers).
1.2. Appearance inspection: The insulation rod has no cracks, damage or aging, and the probe and circuit parts are intact.
1.3. Power check: The battery powered voltage tester must ensure sufficient power; The electronic voltage tester needs to confirm that the sound and light alarm functions are normal.
2. Safety protection
2.1. Personal protection: Operators must wear insulated gloves, insulated boots, and stand on insulated pads.
2.2. Guardianship requirement: One person must operate and one person must supervise, with the operator in front and the guardian behind.
2.3. Safe distance: Maintain a distance according to the voltage level (such as 10kV ≥ 0.7m, 35kV ≥ 1.5m), and do not directly hold the contact device.
3. Operating standards
3.1. Step by step electrical testing: First, conduct remote sensing, then slowly approach the charged body, confirm the alarm, and immediately withdraw.
3.2. Environmental restrictions: Do not use in rain, snow, fog, or high humidity environments (waterproof type is required in emergency situations).
3.3. Prevent misjudgment: Strong electromagnetic fields or residual charges may interfere with the results and require multiple verifications.
4. Equipment management
4.1. Regular testing: Conduct preventive testing every six months, and prohibit the use of expired or untested voltage testers.
4.2. Prohibit the use of unqualified products: It is necessary to use a voltage tester that has been technically evaluated and matches the voltage level.
4.3. Storage requirements: Store in a dry and ventilated place, avoiding direct sunlight or contact with corrosive substances.
