Comprehensive Evaluation System of Ground Grid Condition Based on Magnetic Flux Detection

Abstract

The invention discloses a ground network status comprehensive evaluation system based on magnetic flux detection, which includes two parts: hardware and program software: the hardware includes a magnetic flux detector and a computer, the computer communicates with the magnetic flux detector, and the magnetic flux detector is used for the ground network Corrosion degree signal acquisition, the computer is used to read the data fed back by the magnetic flux detector and compare and analyze the preset corrosion data, thereby generating a comprehensive evaluation report; the present invention quickly and easily generates The comprehensive evaluation report of the ground grid status greatly facilitates the substation maintenance personnel to fully and accurately grasp the status of the ground grid, which is fast, accurate and efficient, thus effectively ensuring the safe and stable operation of the grid and electrical equipment. The comprehensive evaluation system of the present invention can greatly improve work efficiency, save a lot of manpower, material resources and financial resources, and has great economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of ground network detection in power systems, in particular to a comprehensive evaluation system for ground network conditions based on magnetic flux detection. Background technique [0002] The ground grid of transmission line towers and substations will be reduced in diameter or rusted after being corroded, resulting in an increase in the grounding resistance of the ground grid and a decrease in conductivity, which poses a great threat to the safe and stable operation of the substation equipment and the grid. Doing so will damage the equipment and cause an accident. At present, the traditional method of ground network detection and its shortcomings are as follows: 1. Measuring the ground resistance with a ground shaker or clamp meter cannot truly reflect the corrosion and rust of the ground network, the depth of burial and the form of laying; 2. 1. Excavation sampling inspection can only reflect the situa...

[0002] The ground grid of transmission line towers and substations will be reduced in diameter or rusted after being corroded, resulting in an increase in the grounding resistance of the ground grid and a decrease in conductivity, which poses a great threat to the safe and stable operation of the substation equipment and the grid. damage to the equipment and cause an accident

At present, the traditional method of ground network detection and its shortcomings are as follows: 1. Measuring the ground resistance with a ground shaker or clamp meter cannot truly reflect the corrosion, rust breakage, burial depth and laying form of the ground network; 2. 1. Excavation sampling inspection can only reflect the situation of the excavation site but not the overall situation of the ground network; 3. There are also domestic attempts to detect the ground network by means of radar detection, but the radar can only detect the direction of the ground network and blurred images, it is impossible to accurately locate the ground network pipeline, and it is difficult to judge the corrosion and rust of the ground network steel bars
