Title:
TRANSMISSION LINE BREEZE VIBRATION SENSING DEVICE AND METHOD, AND TRANSMISSION LINE BREEZE VIBRATION EARLY WARNING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/016732
Kind Code:
A1
Abstract:
A transmission line breeze vibration sensing device and method, and a transmission line breeze vibration early warning device and method. The transmission line breeze vibration sensing device comprises: a wire clamp (1) of a hollow cylindrical structure, a vibration sensor (7), a plurality of pressure sensors (6) and a data processing device, wherein the wire clamp (1) is hung on a ground wire of a transmission line; the wire clamp (1) is connected to the data processing device; the vibration sensor (7) and the plurality of pressure sensors (6) are arranged in the wire clamp (1) and are in communication connection with the data processing device; and the data processing device is configured to process the ground wire surface pressure collected by each of the pressure sensors (6) and the ground wire vibration acceleration collected by the vibration sensor (7) to obtain a ground wire pneumatic force, a ground wire vibration displacement, a ground wire vibration frequency and a ground wire dynamic bending strain, and send same to a remote server. The sensing device implements synchronous monitoring of the sag of the ground wire and the pneumatic load of the ground wire to provide complete basic data for providing disaster early warnings regarding the breeze vibration of the ground wire of the transmission line.
