Zusammenfassung: | The invention discloses a vibration monitoring system and a vibration monitoring method for divided conductors. The vibration monitoring system comprises a divided conductor vibration monitoring device (25), optical fiber (26), an optical fiber composite overhead ground wire (29), a fiber bragg grating demodulator (30) and a computer system (31). According to the vibration monitoring system and the vibration monitoring method, vibrations of the divided conductors of a power transmission line in three directions, especially the integral torsional vibration and the sub-conductor torsional vibration of a divided conductor beam are monitored, and the multipoint real-time monitoring can be carried out on the torsional rigidity of the power transmission line; and various types of divided conductors can be monitored through simple transformation, and the influence on the inherent property of the line is less. The defects that a field power supply is needed, the anti-electromagnetic interference capability is poor an |
