Description

Technical Field

[0002] Wire resistance testing is a crucial part of electrical safety inspection, playing a vital role in fire prevention, ensuring normal equipment operation, and improving energy efficiency. Below is a detailed explanation of wire resistance testing. The Importance of Wire Resistance Testing: As the medium for electrical energy transmission, the performance of wires directly affects the safety, stability, and efficiency of the entire power system. Resistance is one of the important indicators of wire performance. Through resistance testing, we can understand the conductivity of the wire, promptly identify potential safety hazards, and ensure the normal operation of the power system.

[0003] Current wire resistance testing requires the use of a multimeter and a testing probe to measure both ends of the wire. The wire must be manually aligned with one end and kept stable. However, hand wobbling can easily occur during alignment, resulting in poor testing quality, inaccurate measurement, and low safety.

[0004] Therefore, it is necessary to redesign and modify the wire resistance testing equipment to effectively prevent the current wire resistance testing method, which requires the use of a multimeter and a test pen to measure both ends of the wire, manually aligning one end of the wire and keeping it stable. During the alignment process, hand wobbling is easy to occur, resulting in poor testing effect and inaccurate measurement. Utility Model Content
