TECHNICAL FIELD

[0001] The present application relates to the technical field of power transmission lines, in particular to a power transmission line entering an equipotential dangerous point automatic marking system and method. BACKGROUND

[0002] A power transmission line is a device that uses a transformer to step up the power generated by a generator and then connects it to the power transmission line through control devices such as circuit breakers. The structure is divided into overhead power transmission lines and cable lines. Overhead power transmission lines are composed of line towers, conductors, insulators, line fittings, stay wires, tower foundations, and grounding devices, and are erected above the ground. According to the nature of the transmitted current, power transmission is divided into alternating current transmission and direct current transmission.

[0003] A notable feature of current live-line work on power transmission lines is the use of equipotential work, that is, the worker enters the high-voltage conductor through an insulating tool and is at the same potential. The key to equipotential work is to choose the right entry path and method, and it must be ensured that the worker's personal safety is ensured when entering and leaving the equipotential.

[0004] However, when the worker enters the high-voltage conductor through the insulating tool, several matters need to be noted, such as not going to dangerous locations and not doing dangerous actions. The matters to be noted are generally counted manually, and thus there is a low efficiency. Therefore, the power transmission line entering the equipotential dangerous point automatic marking method is invented. SUMMARY
