The device comprises an aerial inspection system and a ground monitoring system, and the aerial inspection system includes an unmanned aerial vehicle and an insulation rod installed on the unmanned aerial vehicle. The insulating rod is provided with an electrical inspection module, a first central processing module, a 315MHz wireless transmission module and a 433MHz wireless transmissionmodule. The ground monitoring system includes a 315MHz wireless receiving module, a second central processing module, an audible alarm module, a 433MHz wireless receiving module, a third central processing module, and a light alarm module. The aerial live-line inspection device employing double frequencies and double sources is provided with an aerial electrical inspection device, and a person does not need to climb high for operation, thereby reducing the danger of the person. Moreover, the double frequencies and double sources guarantee the triggering reliability of an alarm.

Description

technical field [0001] The invention belongs to the field of high-voltage electric testing equipment and radio technology, in particular to an electric testing device based on dual-frequency and double-channel wireless trigger transmission line. Background technique [0002] For the maintenance of high-voltage and ultra-high-voltage transmission lines, it is necessary to detect whether the line to be repaired is correctly powered off or has voltage, so as to ensure the safety of operators. High-voltage electrical inspection technology is a relatively mature technology in primary power grid equipment. The traditional electrical inspection method is that the operator carries the electrical inspection device and waits for the tower to use the insulation electroscope to conduct electrical inspection on the line. The insulation performance of the electrical inspection device and the climbing operation There are certain risks in the electrical inspection. At present, the electric...

Problems solved by technology

The disadvantage of this structure is that because the contact of the electroscope is a columnar structure, it is not easy to achieve stable contact with the transmission line, which affects the detection effect

Although this structure can adjust the flight attitude of the UAV, during the automatic adjustment process of the azimuth adjustment structure, the center of gravity will shift, which will affect the stability of the UAV flight process, and there is a risk of hanging upside down; and during the signal transmission process , the anti-interference ability is not strong, and the problem of signal interruption is prone to occur
