The invention discloses a state monitoring system for a grounding grid based on an industrial personal computer. The state monitoring system comprises a ground impedance tester which is used for receiving a test command from a central processor and measuring the power frequency alternating-current parameters of the grounding grid, a direct-current on-resistance tester which is used for receiving a test command from the central processor and measuring the direct-current on-resistance among grounding wires, and the central processor which is used for sending test commands to the ground impedance tester and the direct-current on-resistance tester based on the development of the industrial personal computer, statistically analyzing the measured power frequency alternating-current parameters and the direct-current on-resistance in time and location and evaluating the operating condition of the grounding grid. Based on a grounding grid intelligent measurement system developed by the industrial personal computer, the state monitoring system for the grounding grid based on the industrial personal computer, disclosed by the invention, can test the electrical parameters of the grounding grid in standardization and intellectualization manner, and can collect and analyze the electrical parameters and evaluate the operating condition, so as to effectively reduce errors generated during the measurement and improve the efficiency for the field test.

Description

technical field [0001] The invention relates to the field of safe operation of grounding grids in electric power systems, and more particularly relates to an industrial computer-based grounding grid state monitoring system. Background technique [0002] The grounding grid is one of the important measures to ensure the safe and reliable operation of the power system. When there is an overcurrent in the power system, good grounding can quickly disperse the current into the ground, ensuring the safety of power equipment and staff. However, the grounding grid is buried underground for a long time, and under the influence of the ground current, it is prone to soil electrochemical corrosion, failure or fracture, which affects its ability to disperse and endanger the safety of the power system. Therefore, monitoring the operational status of the grounding grid is crucial. [0003] Chinese utility model patent specification CN201035712 discloses a grounding network wireless detect...

Problems solved by technology

[0004] During the measurement process of the above-mentioned methods and equipment for measuring the electrical parameters of the grounding grid, testers are required to manually record the test data and organize and analyze the workload. It is difficult to ensure the validity and standardization of the test data; and because different testers Different recording habits, incomplete test information records may lead to errors in the analysis of test results and reduce the reliability of the test
