Description

Technical Field

[0001] The invention belongs to the technical field of transmission cable inspection, and in particular relates to an inspection system and an inspection method for power transmission cables. Background Art

[0002] Power transmission cables are an indispensable and important part of the power system, and their operating status is directly related to the stability and safety of the entire power system. However, since cables are usually laid in the wild or at high altitudes, they are easily affected by the natural environment and human factors and are prone to failure or damage. In order to discover and solve these problems in a timely manner and ensure the normal operation of the power system, the inspection system of power transmission cables came into being. As an important link to ensure the stable operation of the power system, power inspection has long relied on manual methods. However, with the continuous expansion and complexity of the power network, manual inspection has gradually exposed many shortcomings and deficiencies. Power inspection is a high-risk job. Inspectors need to face a variety of dangerous factors such as high-altitude operations, high-voltage electric fields, and bad weather. If you are not careful, safety accidents such as falling and electric shock may occur, posing a serious threat to the life safety of inspectors. Especially in complex terrain and extreme weather conditions, the safety risks are doubled. Wind power is one of the important factors affecting the safety of transmission cables. Strong winds may cause cables to dance, break, or cause serious accidents such as tower collapse. If the inspection device cannot monitor wind power, it will not be able to warn of potential wind disaster risks in time, increasing the possibility of damage to the transmission line. Therefore, whether it is possible to provide a patrol system and patrol method that can reduce manual operations and perform mechanical surface patrol and wind patrol on cables is a technical problem that the present invention urgently needs to solve.
