On line stress monitoring device for transmission line tower
model：DX-WPS100-YL
1、 Demand analysis
For the iron tower, due to its dead weight and other loads, it will produce certain strain, and strain is an indirect reflection of stress. The online stress monitoring system for transmission line towers is mainly used to measure the stress of transmission line towers. The stress monitoring of the tower structure is indirectly realized through the strain monitoring, mainly monitoring the stress of the key sections of the tower structure to understand the long-term or transient stress of the structure. The four legs of the power supply tower are receiving points, and they are stressed intensively. Therefore, monitoring the points with representative sections of the tower support can understand the stress state of the main load-bearing components and their state at all times.
2、 Working principle
The transmission line tower stress online monitoring device adopts automatic data acquisition, measurement and periodic acquisition of various data of the tested tower, and uploads the data to the monitoring place for staff to view and analyze. In addition, the system will automatically alarm when the data exceeds a certain coefficient; Moreover, the device has data cloud analysis, which can intelligently manage the tower information and ensure the safe and stable operation of the tower all the time.
