More Information
Summary:The utility model relates to a coal mine high-voltage line cable head failure pre-alarming system, which is capable of monitoring a cable head parameter in the real time and sending out a failure pre-alarming information. The coal mine high-voltage line cable head failure pre-alarming system comprises a wireless sensor (10), a data transponder (20) and a monitor host computer (30), characterized in that: the wireless sensor (10) used for sensing the power supply and provided with a power supply lead is mounted on a joint position of a cable joint, a cable and an aluminum stranded cable; an energy storage component (11) is arranged in the wireless sensor. The data transponder comprises two antennae of different frequencies, the power is supplied mainly by a solar energy or a wind energy (22), a build-in charging accumulator (21) is used as a back-up power supply. The voltage, current and temperature data of the cable head is sent to the data transponder and then processed and transferred to a special IP addres
