Technical Field

[0001] The present invention relates to the technical field of power system monitoring and fire prevention, and specifically to an intelligent mobile transmission line fault, fire risk and wildfire detection device. Background Technique

[0002] In the power system, the safe and stable operation of transmission lines is of utmost importance. Transmission lines may experience various faults, such as broken conductor strands, damaged insulators, overheating of connection points, etc. If these faults are not dealt with in a timely manner, power outages will occur, affecting social and economic development.

[0003] At the same time, fire risks and wildfires pose a serious threat to transmission lines. Fire risks may be caused by the transmission lines' own faults. Once a wildfire spreads near the transmission lines, it will damage power facilities, cause large-scale power outages, and even intensify the fire.

[0004] Currently, transmission line fault detection methods include regular manual inspections and fixed monitoring equipment detection. Manual inspections are inefficient, labor-intensive, and restricted by terrain and weather; fixed monitoring equipment has a limited monitoring range. For fire risk and wildfire detection, satellite remote sensing has a low temporal resolution and is greatly affected by clouds, and ground observation requires a large investment of manpower and material resources with a limited monitoring range.

[0005] Existing detection devices mostly rely on the combination of solar energy and batteries for power supply, but there are problems with unstable power supply in special environments such as insufficient light. Therefore, technicians in this field have provided an intelligent mobile transmission line fault, fire risk and wildfire detection device to solve the problems raised in the above background technique.

[0025] (III) Beneficial effects

[0026] The present invention provides an intelligent mobile device for detecting transmission line faults, fire risks, and wildfires. It has the following beneficial effects:
