Problems solved by technology

Because the grounding resistance value of the grounding grid changes at any time during use, and it changes so that it will gradually decrease over time (the loss of resistance-reducing materials), when the resistance value of the substation grounding grid exceeds the fixed range, it will Prone to accidents, endangering the safety of the country and individuals

Embodiment

[0014] Example: such as figure 1 As shown, the substation grounding grid is composed of horizontally laid grids and vertical grounding electrodes connected to the grids; the grids and vertical grounding electrodes are composed of interconnected metal pipes spliced ​​with each other. It is also possible to retrofit the old substation grounding grid by binding interconnected plastic pipes on the existing grid and vertical electrodes. Connect the ground grid ground resistance measurement module to the substation ground grid, and the ground grid ground resistance measurement module is used to measure the resistance value of the substation ground grid; the ground grid ground resistance measurement module is used to measure the dry humidity, pH and density indicators of the soil. Complete the calculation of the resistance value. Connect the ground grid resistance real-time monitoring module to the ground grid resistance measurement module. The ground grid resistance real-time monit...

Abstract

The invention discloses a system for intelligently regulating a grounding resistance of transformer substation grounding net. The transformer substation grounding net comprises a horizontally paved grid and a vertical grounding electrode connected with the grid. A measuring module of the grounding resistance of the grounding net is connected to the transformer substation grounding net in order to measure the resistance value of the transformer substation grounding net; a real-time monitoring module of the grounding resistance is connected with the measuring module of the grounding resistance of the grounding net so as to collect, calculate, statistically analyze, compare, remote control and store the measured value of the measuring module of the grounding resistance of the grounding net; and a resistance-decreasing material supplement module is connected with the transformer substation grounding net and is controlled by the real-time monitoring module of the grounding resistance in order to supplement the resistance-decreasing material to the transformer substation grounding net and keep the grounding resistance of the transformer substation stable.

Description

technical field [0001] The invention relates to an intelligent adjustment system for grounding resistance of a substation grounding grid, which belongs to the technical field of lightning protection grounding grids. Background technique [0002] After the initial calculation and laying of the substation grounding grid, the subsequent resistance value is generally not measured, but in the actual use process, the substation grounding resistance will change at any time, and the main factors affecting the grounding grid resistance The factors are terrain and geological conditions, followed by climate conditions and meteorological conditions such as sunshine and rain, and other factors such as the area of ​​the ground network. Because the grounding resistance value of the grounding grid changes at any time during use, and it changes so that it will gradually decrease over time (the loss of resistance-reducing materials), when the resistance value of the substation grounding grid ...
