Background technique

With the development of the power grid, the number and complexity of electrical equipment in substations have increased dramatically, and it has become increasingly difficult to inspect the operating status of on-site equipment. In the past, the monitoring of the operation status of on-site equipment was mainly completed by regular inspections by the personnel on duty in the substation, which has the following disadvantages: 1. The inspection interval is long, and the real-time performance of equipment problems is poor; 2. The work is dangerous, and the equipment in the factory area where the inspection personnel is located has high voltage. , prone to personal injury accidents, endangering personal and equipment safety; 3. It consumes a lot of manpower and material resources, and the inspection requires the on-duty personnel to go down to the site to check the equipment one by one, which is inefficient and easy to miss inspection; 4. The inspection accuracy is poor, and infrared thermometers are widely used The remote inspection of other equipment is far away from the equipment under test. In addition, the site environment is complex and there are many interference factors, resulting in low detection accuracy. In addition, various abnormalities and faults often occur in power grid equipment, such as water ingress, insulation drop, overheating, fire, etc. If they are not discovered in time, it is very likely to cause irreparable losses, which brings great troubles to substations .
