Problems solved by technology
At present, the commonly used electrical testing techniques include ultrasonic testing, infrared thermal imaging testing, pulse current testing and chemical testing, etc., but the methods currently used have different defects. Thermal imaging technology cannot realize early warning of early discharge. Therefore, in order to detect weak discharge phenomena as early as possible and provide early warning of equipment failures, a new power line discharge corona detection method is urgently needed.

The invention discloses a power line discharge corona detection device and method.The power line discharge corona detection device comprises an unmanned aerial vehicle, the unmanned aerial vehicle is provided with a slit rotation orientation device, and the slit rotation orientation device comprises an ultraviolet light detection device, a central processing unit, a positioning device and a storage device; the ultraviolet light detection device comprises a shell, a motor, a power supply and an information acquisition device, the motor is used for driving the shell to rotate, the shell is a cylindrical shell, a plurality of uniformly distributed slits are formed in the side surface of the cylindrical shell, and the information acquisition device is used for acquiring ultraviolet light signals through the slits. According to the power line discharge corona detection device and method provided by the invention, the discharge positioning precision is improved, compared with a single-path receiving sensor and a multi-path receiving sensor, the false detection and omission ratio is reduced, and the device and the method have important significance for preventing transmission line transmission faults caused by long-term accumulation of weak corona phenomena.
Description
technical field [0001] The invention relates to the technical field of power line corona detection, in particular to a power line discharge corona detection device and method. Background technique [0002] Corona discharge is the phenomenon of air ionization and discharge caused by corona on the surface of high-voltage transmission lines. life. Therefore, regular inspection and maintenance of power lines is required. At present, the commonly used electrical testing techniques include ultrasonic testing, infrared thermal imaging testing, pulse current testing and chemical testing, etc., but the methods currently used have different defects, such as ultrasonic testing only for fixed-point fault detection, infrared Thermal imaging technology cannot realize early warning of early discharge. Therefore, in order to detect weak discharge as early as possible and give early warning of equipment failure, a new method of corona detection for power line discharge is urgently needed. ...
