The utility model provides a device for monitoring a cable short circuit. The device comprises a cable power supply junction box, a cable, a cable terminal junction box and a digital display ampere meter, the cable power supply junction box is connected to the digital display ammeter through a cable; the cable terminal junction box is fixedly connected with one end of the cable; a temperature sensing cable is arranged in the cable, the digital display ammeter is used for monitoring a current signal value in the temperature sensing cable in real time, and if the monitored current signal value is not equal to a preset current signal value, it is judged that the cable is short-circuited. The temperature sensing cable is specially used for providing a basis for judging the short-circuit point of the cable, so that a maintainer can quickly find a short-circuit loop, the time for finding the short-circuit point is greatly shortened, the cost of adding the temperature sensing cable into the cable is lower than that
