Problems solved by technology

[0004] 1. The test device system is complex and dangerous;
[0005] 2. Each test item needs to be tested separately, the test steps are cumbersome, and the resulting data processing tasks are heavy;
[0006] 3. Only the performance of the ground network at the detection point can be assessed, and it cannot effectively reflect the performance of the real entire ground network
[0007] Therefore, it is necessary to study a test method that is compact in structure, easy to operate, simple in the test process, capable of automatically collecting and processing the result data, and can comprehensively and truly evaluate the performance of the ground grid in a large range, so as to avoid the inability to be effective due to too few detection points. Reflect the real performance of the ground network

Abstract

The invention discloses a grounding grid performance detection method and system based on a wireless sensor network. The detection system is simple in structure. Multiple groups of test data can be obtained simultaneously through one test, the test speed is high, and the efficiency is high. The data is analyzed and calculated through the analysis platform, step voltage result data of multiple groups of test points can be obtained, so that the purpose of comprehensively examining the performance of the whole earth screen is achieved, and the result is real and comprehensive. According to the method, singular detection points existing in the result can be observed more visually by scanning and measuring the condition of the whole ground net, the ground net is improved more specifically, test errors caused by underground soil, pipe network distribution, damage to a part of the ground net and other factors can be effectively eliminated, the condition of the ground net is effectively and truly reflected, and the method has high accuracy.

Description

technical field [0001] The invention belongs to the technical field of grounding grids, and in particular relates to a performance detection method for grounding grids based on a wireless sensor network. Background technique [0002] For a long time, the focus of domestic attention has been mainly on the most basic parameter of the grounding grid - grounding impedance. The safety assessment of the grounding grid only considers whether each characteristic parameter index meets the respective specified limits. According to "GB / T50150 - According to the provisions of the 2016 Electrical Equipment Installation Engineering Handover Test Standard for Electrical Equipment, the test items for the grounding grid include the following: 1. Electrical integrity test of the grounding grid; 2. Grounding impedance; 3. Surface potential gradient of the site, contact Potential difference and step voltage measurements. For the electrical integrity test of the grounding grid, the electrical c...
