Title:
CABLE EARLY-WARNING MONITORING TEST PLATFORM
Document Type and Number:
WIPO Patent Application WO/2021/212816
Kind Code:
A1
Abstract:
A cable early-warning monitoring test platform, comprising: a heating device (2) configured to heat a cable (1) to simulate heating of the cable (1) at a fault point, the cable (1) being provided with a temperature measurement optical fiber; an optical fiber temperature measurement host (4) configured to irradiate the cable (1) using pulsed light, backward Raman scattered light generated in a propagation process of the pulsed light on the temperature measurement optical fiber being received by the optical fiber temperature measurement host (4); and a platform host (6) configured to locate a cable fault point according to the backward Raman scattered light and calculate the temperature of the cable fault point. According to the cable early-warning monitoring test platform, the heating device (2) is used to heat the cable (1) to simulate heating of the cable (1) at the fault point, the optical fiber temperature measurement host (4) irradiates the cable (1) using the pulsed light, the backward Raman scattered light is generated in the propagation process of the pulsed light on the temperature measurement optical fiber, the backward Raman scattered light is received and transmitted to the platform host (6), and the platform host (6) calculates the position and temperature of the cable fault point according to the backward Raman scattered light, so as to verify the system reliability of an online monitoring platform for the cable (1).
