[0001] The invention belongs to the field of electric power construction, and in particular relates to a method for an insulated boom truck to pass through an obstructed road surface. Background Art

[0002] Against the backdrop of rapid social and economic development, the number of sensitive and important users at all levels of the company continues to increase, and power customers are increasingly expecting uninterrupted power supply. The traditional power outage maintenance model can no longer meet the quality requirements of power supply reliability and high-quality services, and the maintenance complaints caused by frequent power outages in the distribution network are becoming more and more prominent. The distribution network uninterrupted power operation is an operation method for maintaining power supply to users by using live operation, bypass operation and other methods to repair distribution network equipment, which has become the main means of distribution network maintenance.

[0003] At present, the non-stop power supply operation of the distribution network is mainly carried out by insulating gloves, with an insulating boom truck as the main insulation. However, the traditional insulating boom truck is restricted by the terrain environment, such as potholes, ridges, mud, holes, etc., and cannot reach the operation site, reducing the coverage of non-stop power supply operation. The crawler-type insulating boom truck still cannot effectively pass through the occasions where the holes are too large and the ridges are too high. Summary of the invention
