Zusammenfassung:The utility model discloses an air suction type cable fire early warning system. According to the system, at least one air collection branch pipe is buried in each monitoring point, air of each monitoring point is led to a gas detection chamber under the action of an air suction pump to detect and judge whether abnormal gas is contained in the air or not, and then whether the temperature of a cable wrapping material is abnormal or not is judged to warn a fire disaster. A fire hazard is warned by detecting gas decomposed by the cable wrapping material under an over-condition, and the warning time period can be 30-40 minutes. Besides, the water immersion sensor is arranged at the bottom of the water-vapor separation chamber, so that whether the monitoring point is flooded or not can be detected; the liquid level sensor is arranged at the middle upper part of the water-vapor separation chamber, so that the flooding condition of the monitoring point can be monitored, and when the monitoring point is seriously flo
