MONITORING APPARATUS FOR ELECTRIC POWER TRACK, OPTICAL GROUND WIRE OR STRUCTURE FOR THE TRACK USING PIEZOELECTRIC ELEMENT AND POWER SUPPLY FOR THE MONITORING DEVICE

摘要

According to an embodiment of the present invention, a device to monitor a transmission line, an optical ground wire, or a structure for a track using a piezoelectric element includes: a power supply unit charging a battery by using electric energy, generated from the piezoelectric element placed in a structure connected to the optical ground wire or transmission line, and supplying the electric energy from the battery to a device in the monitoring device, requiring the electricity. More specifically, the piezoelectric element is installed at a predetermined height from the structure to the ground to generate electric energy with vibrations. According to the device to monitor a transmission line, an optical ground wire, or a structure for a track using a piezoelectric element, the abnormality of the transmission line, the optical ground wire, or structure for a track is able to be monitored without extra external power supply to previously prevent a blackout.
