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 high-voltage transmission lines, the complexity of the 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 high-voltage line automatic fault detection device of this embodiment can be structured from figure 1 , figure 2 with image 3 It can be seen that the device is a pod 5 fixed on the bottom of the helicopter and carrying a detection platform capable of automatic image data collection. The pod 5 is a cylinder with a spherical bottom. There is a detection platform 8 fixed to the bottom of the pod 5. The pod 5 is connected to the stepper motor 2 with brake on the helicopter through the magnet shock absorber and the attitude controller. Connect and install horizontal and vertical gyro stabilizers in the pod 5 to maintain the stability of the detection platform 8 in the pod 5 during flight.

[0018] The detection platform 8 includes an optical camera 7 and an infrared fault scanner 11 with a camera. 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 de...

Embodiment 2

[0031] Embodiment 2 The high-voltage line fault detection device of this embodiment can be structured from Figure 4 It can be seen that it is different from Embodiment 1 in that the magnet connecting the pod 5 and the aircraft's magnet shock absorber on the bottom surface of the outer shell 16 can also be a DC electromagnet 25, and a pressure sensor is installed on the inner core 18 to make the direct current The magnetic flux of the magnet 25 can be adjusted by receiving the signal of the pressure sensor by the microcomputer to realize online real-time adjustment, which can reduce the vibration as much as possible, which helps the optical camera 7 and the infrared fault scanner 11 to collect images.

Description

1. Technical Field [0001] The invention relates to a high-voltage line maintenance method and device, in particular to a device installed on a remote-controlled helicopter for automatic line 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 caused by lightning overvoltages, short-term contact with lines caused by strong winds, discharge through the bodies of birds, and falling objects such as branches. 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 economy, there are more and more high-voltage transmission lines in various places. However, due to the long distance of high-voltage transmission lines, the complicated geographical situation and the limitatio...
