The side of the high-voltage cable fault monitoring and positioning body away from the underground pipe gallery body is covered with the constant-temperature protection assembly. The document also discloses that the fault positioning principle of the high-voltage cable fault monitoring and positioning device is that the current and voltage of the cable to be measured are collected by means of current and voltage transformers, and then uploaded to an upper computer. The position of the cable fault can be determined by means of pulse method, audio path method, electromagnetic pre-determined point method, resistance bridge method, inductance flash discharge sound measurement method, and step voltage positioning method, etc., to realize fault positioning.

[0003] In the above-mentioned scheme, the fault monitoring and positioning device in the cable pipe gallery is prevented from being damp by the flexible waterproof film. In the prior art, the detection data of the cable condition is transmitted to the monitoring upper computer for analysis.
