Abstract

The invention provides a cable fireproof protection method and related equipment, and the method comprises the steps: S1, enabling a to-be-monitored cable to be divided into N feature cable segments,and enabling a temperature measurement optical fiber to be divided into M optical fiber temperature measurement points; S2, detecting the temperature of the N sections of characteristic cable sectionsin real time through M optical fiber temperature measuring points, and when the i optical fiber temperature measuring point detects that the N sections of characteristic cable sections have firehazard points and gives an alarm, automatically calculating the positioning information of the i optical fiber temperature measuring point by related equipment; and S3, according to the positioning information, the related equipment tripping off the circuit breaker of the fault cable section. Compared with the prior art, the cable fireproof protection method and the related equipment thereof fully utilize the optical fiber temperature measurement positioning information, analyze the distribution condition of the positioning information in the network, realize segmented protection, and adopt an energy blocking mode to realize active prevention and prevent fire disasters.

Description

technical field [0001] The invention belongs to the technical field of power transmission, and in particular relates to a cable fire protection method applied to secondary power cables and related settings. Background technique [0002] Cables are distinguished from applications and can be divided into primary cables and secondary cables. The primary cable is an important carrier of primary power transmission, and the secondary cable is the main carrier of the secondary protection system. The fire prevention of primary cables has introduced fiber optic temperature measurement technology earlier, and has achieved certain results; the fire prevention of secondary cables has been paid more and more attention, and fiber optic temperature measurement is an important technical direction. The wiring methods of the primary and secondary cables are completely different. Although they are all optical fiber temperature measurement, the technical problems that need to be dealt with are...
