Description

technical field [0001] The invention relates to an automatic loading and unloading type high-voltage overhead line mutual inductance power-taking device mainly used in a high-voltage line inspection device of an electric power system, and belongs to the technical field of high-voltage line inspection of an electric power system. Background technique [0002] The research on line inspection devices for overhead transmission lines at home and abroad began in the late 1980s, initiated by Japan, the United States, Canada and other countries. Domestic related research started relatively late. So far, most of the research on line inspection devices for overhead transmission lines at home and abroad It is still in the laboratory development stage, and there is no mature product applied to the line inspection operation of the actual transmission line. Among them, the continuous power supply problem of the line inspection device is an important obstacle for the actual application of ...

AI Technical Summary

Problems solved by technology

[0005] One is the case where the line patrol device only carries batteries: the need to replace the battery for the line patrol device will cause excessive labor costs, and the line patrol device generally works on overhead lines, so it is difficult to replace it frequently. Operations such as equipment off-line, battery replacement, and equipment on-line will cause the offline time of the line inspection device to be prolonged. At the same time, frequent such operations will undoubtedly increase the probability of operators facing personal safety threats;

[0006] The second is the situation that the line inspection device carries solar panels: the solar panel power collection device is either too large, or the power collection efficiency is not high, and the factors affected by the external environment are relatively high

[0009] (1) The increase of labor cost is the trend of social development. Since the labor law stipulates that the wages of employees will increase year by year, the labor cost will increase accordingly

When the line inspection device is out of power, manpower is required to operate under high-voltage power supply, which poses a serious threat to the personal safety of construction workers and does not meet the requirements for power supply safety.

Although construction personnel are professionally trained, human behavior is always affected by the surrounding environment. In the depths of cold mountains or hot summer days, it is inevitable that misoperation will occur and cause harm to the staff;

[0010] (2) In the case of frequent replacement of the power supply of the line inspection device, the working dead zone of the line inspection device is caused, which greatly reduces the working efficiency of the line inspection device;

[0011] (3) The solar panel is too large, and it cannot work under conditions such as rain, snow and dark nights;

[0012] (4) The fixed mutual inductance power-taking device must make the energized cable pass through the annular mutual inductance coil, and the high-voltage line inspection device will inevitably encounter obstacles such as shockproof rods, insulators, and suspension clamps during the inspection process. The fixed mutual induction device cannot pass through such obstacles, so it cannot continue to perform line inspection tasks together with the line inspection device
