Multi-port self-inspection type electrical test grounding apparatus

Abstract

The invention provides a multi-port self-inspection type electrical test grounding apparatus. The multi-port self-inspection type electrical test grounding apparatus comprises a grounding wire box and a self-inspection apparatus which is arranged on the grounding wire box, wherein the grounding wire box comprises a wire spool and an auxiliary bracket; the wire spool adopts a dual-layer structure with an inner layer and an outer layer, wherein a fixed plate is arranged on the inner layer while a movable plate is arranged on the outer layer; the self-inspection apparatus comprises a self-inspection circuit and a prompter; the fixed plate is provided with multiple test binding posts and an indicator lamp port; a working indicator lamp is arranged in the indicator lamp port; and the working indicator lamp is connected with the prompter. The grounding apparatus provided by the invention is safe, portable, universal and easy to operate, thereby enabling the grounding wires to be simple and concise and disassembled conveniently on the testing site; meanwhile, the time of assembling and disassembling the grounding wires by the test equipment is reduced to be about half of the original time; in addition, the grounding apparatus has the reliable self-inspection function, thereby improving the self-inspection accuracy of the grounding wires to be 99.5%; and therefore, the multi-port self-inspection type electrical test grounding apparatus is worthy of wide popularization and application.

Description

technical field [0001] The invention belongs to the technical field of electrical test grounding devices, in particular to a multi-port self-inspection type electrical test grounding device. technical background [0002] Grounding is an effective safety measure to ensure the normal operation of electrical equipment and personal safety. The grounding device introduces leakage current, static charge and lightning current that may be generated on electrical equipment and other production equipment into the ground, thereby avoiding personal electric shock. , equipment damage and possible fire, explosion and other accidents; especially in the electrical test, both the test instrument and the tested equipment must be grounded. Only in this way can the safety of the test personnel be guaranteed and the needs of the test can be met.

Problems solved by technology

[0003] However, in the actual operation of the electrical test, there are often the following deficiencies: 1. During the on-site test, each instrument and equipment used must be grounded with a ground wire. The grounding of the equipped grounding wire often leads to messy wiring on the test site, and time-consuming assembly and disassembly; 2. Before using the grounding wire, it is generally checked whether the grounding wire is intact with the naked eye, and the correct rate of self-inspection is low; especially the assembly and disassembly of the grounding wire is time-consuming and laborious. Moreover, electric leakage or even electric shock accidents are often caused due to improper assembly and disassembly, which has great potential safety hazards.
