Abstract
A mechine in order to warn of transmission lines galloping, reduce the loss caused by transmission lines galloping. Aiming at a transmission system, a set of lines galloping storage and testing device is developed. The device takes STM32 as the control core to realize signal conditioning, data storage, serial communication and other functions. In the design of the software, the method of single external trigger and multiple internal trigger is adopted to effectively avoid the false trigger phenomenon in weak oscillation, so as to test and store the acceleration of the wire when it gallopings violently. The acceleration sensor and the storage test device directly install on electric wire, and it can detect and record the acceleration data in the process of wire galloping.After the test, the recovery device uses the upper computer to read the detected data and display the waveform, which can provide important experimental basis for the theoretical analysis and parameter setting of the lines galloping.
