Brief introduction of the scheme:
Power cable transmission current overload, large impedance at the cable joint, aging of the insulation or partial discharge of the cable itself, etc., cause the temperature of the cable surface to rise, and the cable insulation and protective layer produce smoldering, accompanied by the generation of large heat and flammable gas. As the temperature rises further, smoke is produced, which develops into a fire. Therefore, a cable failure will first generate a lot of heat. The DTS distributed optical fiber temperature measurement early warning system monitors the temperature change of the cable in real time, so as to accurately determine the abnormality of the cable in the early stage of the accident, and prevent problems before they occur.
Program details:
Monitoring object:
High-voltage power cable and cable joint temperature and fault point detection
Temperature monitoring of cable shaft, bridge frame, cable tunnel, mezzanine and cable trench
High-voltage switchgear contact and cable head temperature monitoring
System Features:
Continuous distributed temperature monitoring, detecting optical cable as both a transmission carrier and a sensor
Positioning accuracy 0.5m, temperature resolution 0.1℃, temperature accuracy ±1℃
The detection optical cable is completely passive, anti-electromagnetic interference, anti-vibration and explosion-proof, corrosion-resistant, and can work in harsh environments
Multi-channel measurement, expand the monitoring range
System functions:
Real-time monitoring of power cable surface and cable joint temperature
Cable current carrying capacity analysis
Cable fault point detection
Multiple alarm type combination settings, effectively avoiding false alarms
Multi-channel and multi-zone measurement, different alarm modes can be set in different areas
