Description

Technical Field

[0001] This utility model belongs to the field of live tool testing technology, and in particular relates to an electric voltage regulator test bench. Background Technology

[0002] Insulating tools are typically made of materials such as polyvinyl chloride (PVC) and polypropylene, possessing excellent insulation properties that effectively prevent current from passing through. Insulating tools play a crucial role in live-line work, ensuring the safety of workers and equipment. Metal tools: Although metal tools are inherently conductive, in live-line work they are usually used for specific tasks, such as grounding operations. Metal tools require special treatment to ensure they do not cause harm to workers during use. Insulating gloves and boots: These tools are essential protective equipment in live-line work, effectively isolating current and protecting workers. Insulating gloves and boots are typically made of special insulating materials, possessing good electrical properties and mechanical strength. Voltage detectors: Used to detect whether high-voltage equipment is energized, ensuring workers confirm its energization before contacting it, thus avoiding the risk of electric shock. Voltage detectors are typically made of metal probes and insulating materials, simple to operate, and safe to use. Personal protective equipment: Including safety helmets, safety glasses, and protective clothing, this equipment is equally important in live-line work, protecting workers from electric shock and other injuries.

[0003] Usage Scenarios and Safety Precautions: Dual Electrical and Mechanical Loads: Live-line working tools need to withstand both electrical and mechanical loads during operation. Therefore, the quality of the tool directly affects the safety of the operator and the equipment. The tool should be safe and reliable, have a reasonable structure, sufficient strength, and be manufactured with advanced technology, lightweight, and flexible.

[0004] To ensure the electrical safety of live-line working tools, regular inspections are necessary. When measuring live-line tools, different voltages need to be applied depending on the type and model of the tool. Conventional voltage regulators are operated manually, which is labor-intensive, poses safety hazards, and often results in inaccurate values, negatively impacting test results. Currently, there is a need to design an electric voltage regulator test bench to achieve automated operation, improve voltage regulation accuracy, provide intuitive parameter display, and increase testing efficiency.
