High-altitude fall prevention method and device for power transmission line
نویسندگان
چکیده
This paper analyzes the structure of transmission line towers and live working conditions, draws conclusions on importance necessity studying methods devices high-altitude fall prevention for lines. Combining actual situation pole tower, in view poor manufacturing technology tower anti-falling track, size anti-dropping device track are not matched, connection point is misplaced, a new type adjustable developed to address cross-arm movement personnel during work. The alternate use backup protection ropes seat belts cumbersome. An alternative safety rope was developed. Aiming at without tracks, drone-based method developed, an anti-fall manipulator operations.

UAV Low Altitude Photogrammetry for Power Line Inspection
When the distance between an obstacle and a power line is less than the discharge distance, a discharge arc can be generated, resulting in the interruption of power supplies. Therefore, regular safety inspections are necessary to ensure the safe operation of power grids. Tall vegetation and buildings are the key factors threatening the safe operation of extra high voltage transmission lines wit...
متن کاملAn oxygen enrichment device for lowlanders ascending to high altitude
BACKGROUND When ascending to the high altitude, people living in low altitude areas will suffer from acute mountain sickness. The aim of this study is to test the hypothesis that whether an oxygen concentration membrane can be made and used to construct a new portable oxygen enrichment device for individuals in acute exposure to the high altitude. METHODS The membrane was fabricated using vin...

متن کاملAnalysis and Experimental Evaluation of Power Line Transmission Parameters for Power Line Communication
The article describes a way of evaluating the power line channel frequency response and input impedance by means of the linear time-invariant (LTI) power line generator. Two possible methods are introduced for the calculation of primary parameters: the first method depends on the physical realization and physical dimension of the cable, and the second method is derived from the data provided by...
متن کاملWavelet-Based Method for Transmission Line Fault Detection and Classification during Power Swing
Power swing caused by various disturbances will affect distance relay behavior and may result in relay misoperation. This paper provides a new wavelet-based method for detection and classification of transmission line faults during power swing. The multi-resolution analysis based on wavelet transform (WT) has the ability to decompose the analyzed signals into different frequency bands. With the...
