[0002] A substation is a place in the power system where voltage and current are transformed, electric energy is received and distributed. The substation in a power plant is a step-up substation, and its function is to step up the voltage of the electric energy generated by the generator and feed it into the high-voltage power grid. When working in a substation, line maintenance is one of the essential tasks. The purpose of line maintenance is to promptly discover problems with the line and eliminate defects in time when problems are found, improve the health level of the equipment, prevent accidents, and ensure the safe operation of the line. Nowadays, when performing maintenance work on high-altitude lines in substations, maintenance personnel usually wear safety belts and stand in a protective hanger. They use lifting equipment to lift the protective hanger and maintenance personnel to a suitable height for high-altitude maintenance.

[0003] In the related art, when maintenance personnel stand in a protective hanger to perform high-altitude operations for line maintenance, they wear a safety belt and hook the hook on the safety belt on the guardrail to protect the personal safety of the maintenance personnel. However, the length of the connecting rope between the safety belt and the hook is limited. When the maintenance worker needs to change the position of standing in the protective hanger to perform line maintenance at different positions, he needs to first remove the hook on the safety belt from the guardrail, and then walk to the required position and re-hook the hook on the safety belt to ensure the safety of the next line maintenance. When the maintenance personnel change their standing position many times, they need to untie the hook of the safety belt through repeated operations, which makes the maintenance of the line inconvenient. Therefore, we propose a power station protective hanger that is convenient for line maintenance to solve the above problems. Utility Model Content
