Magnetic flux detection-based earth screen state comprehensive evaluation system

Abstract

The invention discloses a magnetic flux detection-based earth screen state comprehensive evaluation system, comprising two parts of hardware and program software; the hardware comprises a magnetic flux detector and a computer, which are communicated with each other; the magnetic flux detector is used for collecting an earth screen corrosion degree signal; the computer is used for reading the data fed back by the magnetic flux detector for comparing with preset corrosion data and analyzing, thus generating a comprehensive evaluation report. The comprehensive evaluation report is fast conveniently generated by comparing and analyzing the detection data and the data in a database, so power transformation maintaining personnel can very conveniently, comprehensively and accurately master the earth screen state, effects of rapidness, accuracy and efficiency are achieved and the safe and stable operation of the power grid and electrical equipment is effectively ensured. According to the comprehensive evaluation system, the work efficiency can be greatly improved, massive manpower, materials and financial resources are saved, and the system 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
