Problems solved by technology

[0003] With the development of the economy, there are more and more high-voltage transmission lines in various places. However, due to the long distance of the high-voltage transmission lines, the complicated layout of the geographical situation and the limitations of the test equipment, the high-voltage transmission lines are especially located in remote areas such as virgin forests and oceans. Or there is no effective, timely, simple and reliable daily maintenance method for the lines that are not easy to enter the area. Only after the fault occurs and then find the fault point to repair it, it cannot prevent unburned, very dangerous, and respond to repair after the problem occurs The time is long, and the losses caused by power outages are also large.

Embodiment 1

[0017] Embodiment 1 The structure of the high-voltage line automatic fault detection device in this embodiment can be seen from Fig. 1, Fig. 2 and Fig. 3. The device is a detection platform fixed at the bottom of the helicopter and carrying automatic image data collection. The pod 5. The pod 5 is a cylinder with a spherical bottom, and a detection platform 8 is fixed to the bottom of the pod 5. The pod 5 is connected to the stepping motor 2 with a brake on the helicopter through a magnet shock absorber and an attitude controller. Connect and install horizontal and vertical gyro stabilizers in the pod 5 to keep the detection platform 8 in the pod 5 stable during flight.

[0018] The detection platform 8 includes an optical camera 7 and an infrared fault scanner 11 with a camera, and a camera port 15 is opened on the pod 5 to facilitate image data collection; an electronic sensor 19 with a Hall element is installed under the camera port 15 to detect electromagnetic waves. Stren...

Embodiment 2

[0031] Embodiment 2 The high-voltage wire fault detection device of the present embodiment, its structure can be seen from Fig. 4, and it is different from Embodiment 1 in that: the magnet shock absorber that connects gondola 5 and aircraft is also possible in the magnet on outer bladder 16 bottom surfaces A DC electromagnet 25 is used, and a pressure sensor is installed on the inner core 18, so that the magnetic flux of the DC electromagnet 25 can be adjusted by receiving the signal of the pressure sensor through a microcomputer, and the online real-time adjustment can be realized, and the vibration can be reduced as much as possible, which contributes to The optical camera 7 and the infrared fault scanner 11 collect images.

Description

1. Technical field [0001] The invention relates to a method and device for overhauling a high-voltage line, in particular to a device installed on a remote-controlled helicopter for automatic inspection of high-voltage transmission lines to realize automatic fault detection. 2. Background technology [0002] In the power system, transmission lines (especially overhead lines) are most prone to failures, such as: flashover on the surface of insulators due to lightning overvoltage, short-term line contact caused by strong winds, discharge through the body of birds, and falling of branches and other objects. Short circuit caused by falling on the wire, etc. Therefore, it is very important to ensure the safe operation of transmission lines. [0003] With the development of the economy, there are more and more high-voltage transmission lines in various places. However, due to the long distance of the high-voltage transmission lines, the complicated layout of the geographical situ...
