Abstract

The invention discloses a safety evaluation system and method of live-line work equipotential entry paths. According to the system and method, the whole process of equipotential entry is displayed in a three-dimensional scenario; safety distance between a body of an operator and a live part, smallest distance between the equipotential work operator and adjacent-phase wires and a combined interval of the equipotential work operator entering and leaving an electric field are dynamically calculated; safety evaluation on equipotential entry paths is achieved. The safety evaluation system and method of live-line work equipotential entry paths has the advantages that entering equipotential paths in live-line work can be visually and automatically evaluated, work of hand computation is reduced, efficiency is improved, and better visual is achieved.

Description

technical field [0001] The invention relates to the technical field of live work on transmission lines, in particular to a safety assessment system and method for live work entering an equipotential path. Background technique [0002] A notable feature of live work on transmission lines is the use of equipotential work, that is, workers enter high-voltage wires through insulating tools and are at the same potential as them. The key to equipotential work is to choose the appropriate entry path and method, and the personal safety of the workers must be ensured when entering and exiting the equipotential. [0003] At present, the safety assessment method for live work entering the equipotential path is generally calculated manually according to the tower design drawings to judge whether the path entering the equipotential is safe. This assessment method requires professional calculations, the process is not intuitive enough, and the manual calculation efficiency is low. , the ...
