摘要
光缆护套中的皱纹钢带与大地之间电阻的大小,可充分反映光缆外护套的完整性,也直接反映光缆线路的可靠与安全程度。光缆护套对地绝缘自动监测系统通过光缆破损查找故障,及时发现,及早维护,使维护由被动的"事后抢修"变为"事前预知"的维护方式。
The resistance value between the corrugated steel tape of fiber optical cable sheath and the ground can reflect the integrality of the sheath fully, as well as the reliability and security of cable line, The automatic monitor system of the insulation between fiber optical cable sheath and ground can discover faults through probing damaged points on cable. Through discovering the faults timely, repair and maintenance can be conducted as soon as possible, which will turn maintenance mode from passive aftercci- dent rush to repair to preventive maintenance.
