The invention discloses an OPGW DC ice-melting
system, and the
system comprises an ice-melting
ground line, an ice covering measurement sensor, an ice covering measurement host, an ice-melting measurement host, a DC ice-melting power supply, a 485
concentrator, a switcher, a monitoring terminal, and an optical cable joint box. The ice-melting
ground line is connected with the ice covering measurement host through the optical cable joint box, and the ice covering measurement sensor is connected with the ice covering measurement host through a single-mode
optical fiber. The ice covering measurement host, the ice-melting measurement host and the DC ice-melting power supply are respectively connected with the 485
concentrator. The ice covering measurement host and the ice-melting measurement host are connected with the monitoring terminal through the switcher. The
system achieves the overtemperature monitoring in a long-distance circuit
ice melting process and circuit
ice melting control under the different conditions in a deicing period through employing the technology of distributed optical
temperature measurement and the technology of on-line analysis. The system achieves the ice covering monitoring of a
power transmission rod
tower under the on-site passive conditions,
electromagnetic radiation resistance conditions and severe monitoring conditions through employing the technology of
optical fiber grating ice covering measurement, and has a higher practical value.
