With the continuous promotion of electric power construction, the corridor resources of the power transmission space are increasingly scarce. The newly planned transmission lines inevitably need to cross some existing transmission lines, so the crossing among the high-voltage transmission lines is a necessary phenomenon to be faced when the power grid is built. When a newly-built line crosses the existing line, two methods of power failure construction and uninterrupted power construction are mainly adopted, and the difference is whether the power failure occurs in the line which is crossed. No matter whether the crossed power transmission line needs to be powered off or not, the net sealing protection is needed to be carried out above the crossed power transmission line so as to prevent dangers caused by careless falling of constructors, leads or tools in the construction process of a new line. Therefore, the high efficiency and the safety degree of the net sealing directly determine the construction progress and the safety of the whole construction process.
