MONITORING DEVICE FOR OPTICAL CABLE RESERVING APPARATUS OF UTILITY POLE

WIPO Patent Application WO/2016/206349

A1

Provided is a monitoring device for an optical cable reserving apparatus of a utility pole. A frame upper horizontal crossarm (6) and a frame lower horizontal crossarm (8) are fixed onto a utility pole (1), and connected to each other via a frame brace (7). A winding part having a reserve cable drum rack (4) is fixed on the frame upper horizontal crossarm (6) and the frame lower horizontal crossarm (8). A composite power-optical cable (3) extending from an optical cable connection box (5) is wound on the winding part, and then fixed to the utility pole (1) via a holding hoop (2) and an insulator (9). A grounding knife switch (12) is arranged between the frame upper horizontal crossarm (6) and the frame lower horizontal crossarm (8), wherein an upper connecting wire (11) of the grounding knife switch (12) is connected to the composite power-optical cable (3) extending from the winding part via a wire clamp (10). A guiding optical cable (18) extending from the optical cable connection box (5) is wound on the winding part, and then enters a guiding cable protection tube (19). A monitoring device (14) is arranged on the frame lower horizontal crossarm (8), wherein an upper end of the monitoring device (14) is connected to the grounding knife switch (12) while a lower end thereof is grounded. The monitoring device (14) comprises: a housing (21), an induced current indicator (22), an induced overvoltage counter (23), and a remote data transmission port (16). The induced current indicator (22) is a current transformer, and the induced overvoltage counter (23) is driven to count by another current transformer.
