Abstract

The invention discloses an auxiliary electrode structure for large-scale grounding grid ground resistance measurement. The auxiliary electrode structure is characterized by comprising a central support rack (1) made of metal material, wherein the center of the central support rack (1) is provided with a positioning hole, a central metal post is arranged in the positioning hole, an outer side of the central support rack (1) is connected with six uniformly distributed support arms (4) made of metal material via six rotating pins (3), an end part of each support arm (4) is provided with a positioning sleeve cylinder (5), and a side edge metal post (6) is arranged in each positioning sleeve cylinder (5). The auxiliary electrode structure can help solve a problem of poor ground connection of a conventional auxiliary electrode, test interference can be lowered, test precision can be improved, and convenience of installation and utilization can be improved.

Description

technical field [0001] The invention relates to an auxiliary electrode structure, in particular to an auxiliary electrode structure for measuring the grounding resistance of a large-scale grounding grid. Background technique [0002] When measuring the grounding resistance of large-scale grounding grids, it is necessary to arrange and install measurement auxiliary electrodes. Generally, a channel steel or angle steel with a length of 1000mm to 2000mm is used to drive into the ground to measure the grounding resistance of the grounding grid. Poor grounding of the auxiliary electrode itself can easily affect the test results, making it impossible for the test instrument to perform effective measurements, or making the measurement data highly discrete, making it impossible to judge the test results. At this time, it is necessary to rearrange and install the measurement auxiliary electrodes, and adjust the measurement several times. Installing auxiliary electrodes not only requ...
