Abstract

The invention discloses a power transmission line cable galloping detection method, and the method employs a power transmission line cable galloping detection device to calculate the maximum sag of acable. The power transmission line cable galloping detection device comprises a shell, a power supply module, a main control circuit board, a galloping detection module and a communication transmission module. The power supply module is electrically connected with the main control circuit board, the galloping detection module and the communication transmission module. Cable galloping conditions can be obtained in real time through the remote server, and when the system detects that the galloping amplitude of a power transmission line is too large, an alarm signal is sent to an administrator through short messages, mails and the like; and the signal can be processed timely.

Description

technical field [0001] The invention belongs to the technical field of safety protection equipment for power transmission grids, and in particular relates to a method for real-time monitoring of the galloping state of power transmission line cables. Background technique [0002] Conductor galloping is a serious disaster that endangers the safe and stable operation of transmission lines. In addition, changes in the sag of transmission conductors caused by conductor galloping can also cause tripping, etc., resulting in serious accidents. Statistics show that 70% of the faults in the power system are caused by the collapse of transmission towers and ice-covered ground wires under the action of strong winds. Among them, the collapse of transmission towers and power outages will cause huge economic losses, especially in serious environmental disasters. Sometimes, faults such as transmission lines will have a huge impact on people's daily life and the national economy. Therefore,...
