Jiangsu power transmission tower deformation monitoring device put into trial operation

Jiangsu power transmission tower deformation monitoring device put into trial operation
.
At 16:30 on May 19, the installation of the No.
43 iron tower of 110 kV Buqi Line 816 and the No.
21 iron tower of 110 kV Jingzhou 715I Line No.
21 was successfully completed, and the device was successfully put into trial operation online, and at the same time, a stable and continuous tower deformation curve
appeared in the remote monitoring terminal.

The tower deformation monitoring device is mainly composed of
sensor module, data processing module, energy extraction module and energy storage module.
The whole set of devices has strong anti-interference ability, high electromagnetic compatibility, sleep and wake-up functions, flexible and adjustable data acquisition frequency, data transmission can be retained at breakpoints, and stable test performance, especially in dealing with strong convection and other bad weather, it is at the leading level
in China.

The transmission tower deformation monitoring device is one of the important research results of the science and technology project of State Grid Jiangsu Electric Power Company "Research on Safety Assessment and Protection Technology of
Cross-tower in Strong Convection Weather".
Before the installation of the monitoring device, the professionals of the equipment condition evaluation center carried out long-term simulation assembly and trial operation in the laboratory, communicated and exchanged with professionals, installers and equipment manufacturers for many times, and formulated detailed and thorough work plans and plans for complex on-site conditions, and finally successfully completed the installation of the tower deformation monitoring device
.

The device can realize real-time monitoring and data synchronization transmission of parameters such as tower vibration frequency, deformation acceleration, velocity, displacement, local wind speed and wind direction and temperature
.
"Acceleration and velocity are used to analyze the dynamic characteristics of the tower, guide the correction of the numerical model of the tower dynamics, etc.
, and provide reliable data support
for fully grasping the dynamic performance of the tower.
" The displacement parameters can intuitively reflect the deformation level of the tower, and even the stress-strain state of the components, and can be applied to the correction of the static numerical model to verify the static properties
of the tower.
Parameters such as wind speed, wind direction and temperature provide indispensable boundary conditions
for the static dynamic model of the tower and the failure analysis of the inverted tower.
Zhang Xiaolong, who participated in the research and development of the project at the State Grid Jiangsu Electric Technology Institute, said
.

In the next step, based on the test data of the monitoring device, State Grid Jiangsu Electric Power will further carry out research on transmission tower safety evaluation and early warning technology under strong convective weather, grasp the safe operation status of the tower in real time, and timely carry out risk warning; Provide more scientific maintenance strategies for existing towers, and provide guidance
for the optimization of the whole process of tower design, manufacturing, processing, installation and reinforcement.
At the same time, the optimization design of the monitoring device in terms of energy consumption level, miniaturization, data security and easy installation is carried out to further improve the promotion and application value
of the device.
