Description

Technical Field

[0001] The present invention mainly relates to the technical field of cable grounding, and in particular to a cable installation system for grounding a photovoltaic power station. Background Art

[0002] A photovoltaic power station refers to a power generation system that utilizes solar energy and adopts special materials such as crystalline silicon panels, inverters and other electronic components. It is connected to the power grid and transmits electricity to the power grid. Grounding refers to the connection of the neutral point of the power system and electrical equipment, the exposed conductive parts of the electrical equipment and the external conductive parts of the device to the earth via conductors.

[0003] In the prior art, most photovoltaic power stations are built on mountainous areas or wastelands, and the grounding cables are installed by digging pits and burying them or directly inserting them into the ground. Due to frequent changes in the environment and weather, such as soil loss caused by soft land and water accumulation, grounding needs to be checked frequently. Manual inspections are not only inefficient, but sometimes fail to detect them in time, which leads to leakage in the area. If subsequent manual inspections are not careful, it is easy to cause dangerous situations such as electric shock. Summary of the invention

[0004] The present invention mainly provides a photovoltaic power station grounding cable installation system to solve the technical problems raised in the above background technology.

Then, the insulating suit is worn to pass the conductive area in the grounding cable through the installation ring 132, and then the positioning bolt 133 is tightened, so that the grounding cable and the cable connection assembly 13 can be connected and conductive;

[0059] If the grounding device 10 falls over due to soil loss, the grounding nail 111 and the insulating box 214 will tilt. When tilted to a certain degree, the electrolyte 215 will contact the first copper plate 212. At this time, the first copper plate 212 and the second copper plate 213 complete conduction through the electrolyte 215, and a closed circuit is formed between the battery 216 and the trigger 211. At this time, the trigger 211 operates and sends the alarm information to the remote receiving device 40 through the signal transmission module 30. The staff can quickly lock the grounding device 10 with a problem through the alarm received in the remote receiving device 40 and the location information located by the positioning chip 31, so as to quickly reach the designated area for processing.
