Detection-type tester grounding wire

Abstract

The invention discloses a detection-type tester grounding wire. The grounding wire comprises a grounding wire body, a detection wire, a wiring terminal, a detection module and a grounding wire clamp;the grounding wire body is connected between the wiring terminal and one clamping plate of the grounding wire clamp, and the detection wire is connected between the wiring terminal and the other clamping plate of the grounding wire clamp. The grounding wire has a grounding wire self-detection function, and whether the grounding wire is in a good state or not can be more directly shown. The grounding wire has the function of detecting whether grounding is good or not, and personnel electric injury or instrument burnout caused by poor grounding is avoided. The grounding wire is simple and clearin principle, the grounding wire clamp is used for clamping the 'ground' to form an on-state loop, and whether the grounding wire is well grounded or not can be detected at any time by pressing a small switch. A buzzer can buzz and emit light if the grounding wire is well grounded, the buzzer cannot buzz or emit light if the grounding wire is not well grounded or is not grounded, and the groundingwire has a high identifying degree and can be used in different working environments.

Description

technical field [0001] The invention relates to a grounding wire of a detection type tester. Background technique [0002] Reliable grounding of electrical equipment is one of the technical measures to ensure safety at the production site, and its main purpose is to protect the safety of people and equipment. When electrical equipment with a metal casing leaks electricity or has an internal failure, the grounding wire can prevent it from causing harm to people. [0003] In the daily electrical test work, the test instrument is an indispensable work tool for the work. Test instruments are often equipped with a ground wire to connect the instrument to the grounding device. The grounding pile clamped by the grounding terminal of the grounding wire of the test instrument is often accompanied by a paint surface or an excessively thick oxide layer. In this case, the grounding wire cannot be reliably grounded and cannot effectively protect the instrument. High-voltage tests ofte...

Problems solved by technology

However, in the actual production and life process, due to subjective and objective reasons, the importance of the grounding wire is often ignored

At present, the method of combining wires and clips is often used on site, and the clips are clamped on the reserved grounding piles (poles), which has the advantages of good flexibility, no need for special equipment, and easy implementation on the job site, but the disadvantages are also obvious, such as Unable to judge whether it is reliably grounded, does not have a self-test function, and has a certain degree of potential safety hazard
