The invention discloses a
power cable temperature measuring device. The
power cable temperature measuring device comprises an
embedded processing unit, a temperature measuring sensor unit, a data receiving and
processing unit, a communication module, a display module, a storage unit, an
alarm device and a
supercapacitor power supply group; data measured by the temperature measuring sensor unit arefed into the data receiving and
processing unit through the communication module to process; the data receiving and
processing unit feeds the processed data into the embedded type processing unit; when monitoring that the temperature is abnormal, the embedded type processing unit sends out alarm information to the
alarm device and stores failure information into the storage unit; and the displaymodule is a projection type capacitive touch screen, can display a monitored cable
joint temperature value and a processing result, and can set the
temperature monitoring condition through a screen menu and inquire historic
record. The invention also provides a temperature measuring method of the
power cable temperature measuring device. The power cable temperature measuring device and the temperature measuring method have the beneficial effects of high reliability, full functions and capabilities of effectively reducing failure occurrence times and reducing failure loss.
