Description

Technical Field

[0001] This utility model relates to the field of grounding wires, and in particular to a composite grounding wire. Background Technology

[0002] Grounding wires are crucial safety tools for all types of workers during production. However, currently, three-phase short-circuit wires and grounding wires are generally fixed connections, and the grounding method cannot be changed. This leads to issues where the grounding wire does not meet the required grounding method and makes it difficult to quickly complete wiring operations according to different situations. According to the requirements of the "Electric Power Safety Regulations (Line Section, Power Plant and Substation Section)," the technical measures to ensure the safety of power supply lines and electrical equipment construction are: power outage → voltage testing → grounding wire installation. The current operation uses a contact voltage tester to test for voltage during power outage, combined with a grounding rod for grounding. If, during the time interval between voltage testing and grounding wire installation, a mis-scheduling or misoperation causes the line or equipment to become energized, the subsequent operation becomes grounding while the line is energized, thus posing a threat to the safety of operators.

An adjusting rod 6 is disposed inside the grounding clamp 3, and a spring is disposed between the adjusting rod 6 and the grounding clamp 3 for quick connection and fixing with the cable to be grounded. The rear end of the grounding wire 1 is connected to the grounding clamp 3. The grounding clamp 3 is used to fix the grounding wire 1 to the ground. An electroscope 4 is installed on the side wall of the grounding clamp 3. It is used to determine whether the grounding wire is energized by the change of the induced magnetic field signal. The electroscope 4 is equipped with an alarm device, which is an audible and visual alarm device. When the electroscope 4 senses the magnetic field signal, the alarm device can emit light waves and sound at the same time to promptly remind the operator that the grounding wire 1 is energized, thereby effectively avoiding operator misoperation. A protective cover 5 is installed on the outside of the electroscope 4 and mounted on the grounding clamp 3. The protective cover 5 is a transparent shell structure used to provide protection for the electroscope 4.
