Problems solved by technology

[0004] After market research, it is found that the existing galloping detectors have the following shortcomings, such as unstable power supply of the detector, high power consumption of the system, and the battery needs to be replaced in about three years, resulting in high labor intensity for inspection personnel and on-site installation and construction. The cost is high; the detector itself is heavy and wears the connection of the wires; the galloping detector is not accurate enough to collect data in the XY axis direction; the data of the galloping detector is not encrypted during data collection and transmission, and cannot be connected to the power private network , there are data security risks

Abstract

The invention discloses a galloping detector suitable for an extra-high voltage wire and relates to the technical field of extra-high voltage transmission line galloping monitoring. The galloping detector comprises an STM32L5 main chip, an MEMS acceleration sensor, an encryption chip and a Semtech LoRa chip; the STM32L5 main chip is used for processing the accelerations and angular accelerations of the wire in the X, Y and Z directions acquired by the MEMS acceleration sensor to obtain the amplitude and frequency of galloping; the encryption chip is used for encrypting the amplitude and the frequency sent by the STM32L5 main chip; and the Semtech LoRa chip is used for receiving the encrypted amplitude and frequency and sending the encrypted amplitude and frequency to a data receiving basestation. According to the galloping detector of the invention, the data acquisition precision and the data security can be improved while low power consumption is maintained.

Description

technical field [0001] The invention relates to the technical field of galloping monitoring of UHV transmission lines, in particular to a galloping detector suitable for UHV wires. Background technique [0002] With the extensive construction of UHV power grids, the operation and management of transmission lines are becoming more and more complex, and the occurrence of conductor galloping accidents is becoming more and more frequent. Galloping often causes severe accidents such as wire breakage, disconnection, severe wear and tear of hardware, falling off of towers, tripping of lines, etc., which can easily cause large-scale power outages in the power grid and cause major economic losses to the operation of the power grid. In order to grasp the movement changes of overhead transmission line conductors in a timely manner, conductor galloping detectors must be deployed on relevant lines in galloping-prone areas to collect conductor galloping data in real time. Through the det...
