On October 21, Dingxin Smart Technology's DX-WPS100-WD Multi-Parameter Fusion Intelligent Vibration Online Monitoring Device for Transmission Lines was successfully installed and commissioned on a critical 220kV transmission corridor in Hebei Province. This device, equipped with "high-precision capabilities," will provide round-the-clock protection for the regional power grid against winter swaying hazards.
The DX-WPS100-WD Multi-Parameter Fusion Intelligent Vibration Online Monitoring Device for Transmission Lines comprises a main control module, intelligent processing module, sensing module, power supply module, and communication module, forming a complete monitoring system. Its core sensing module employs high-precision MEMS sensors to capture minute changes in conductor vibration in real time—monitoring frequencies from 0.1 to 50 Hz with amplitude resolution of 0 to 20 m and frequency measurement from 0.1 to 50 Hz.
The data acquisition unit is installed on conductors in sections prone to vibration along the line, continuously collecting real-time conductor motion parameters. After preliminary processing by the edge computing unit, the data is transmitted back to the monitoring center via 4G/5G networks or OPGW fiber optics. When amplitude exceeding the threshold is detected, a multi-level early warning system is immediately activated.
During the debugging phase, the device successfully captured simulated swaying test data: amplitude of 23.7 cm and frequency of 0.82 Hz. These readings align with video monitoring results, validating the system's reliability. Operations personnel stated: "Previously, swaying was primarily assessed through manual observation. Now, with quantitative data support, prevention and mitigation measures can be more targeted."
With the arrival of the winter high-wind season, the DX-WPS100-WD Multi-Parameter Fusion Intelligent Flutter Online Monitoring Device for transmission lines will become a crucial technical measure for ensuring safe line operation. According to estimates, its early warning capabilities can help power grid companies reduce flutter-related faults by over 60%, significantly enhancing power supply reliability.
