Abstract：
 The invention is the monitoring and judging method of safe running of the cable and its equipment. The characteristics are: the said monitoring method through the pre-set fixing threshold and trend threshold sends the alarming information of the overheating situation of the cable core in time; the said judging method is according to the cable surface temperature, the ring temperature and the current value automatically stored to establish the cable surface temperature regression model and forecast the operation trend of the cable surface temperature and promote the judgment through the mathematical analysis of the difference between the forecasting value and the tested value. The invention also provides the device composed of the corresponding thermometric component, the data transmitting wires, the data collecting circuit assembly, the data converting circuit and the computer. The invention has fast storing performance, timely monitoring and stable judging.
