摘要
An on-line detection device for the inner temperature of a power cable joint based on radio frequency technology includes an internal thermoscope (3) and an external receiver (4). The internal thermoscope (3) measures the temperature of the cable joint or the core surface by a direct contact measuring method, and transmits data to the external receiver (4) through an insulating layer by the radio frequency technology. The external receiver (4) also provides power to the internal thermoscope (3) through a radio frequency signal, so that the power supply problem of the internal thermoscope (3) can be solved. An on-line detection method for the inner temperature of a power cable joint using the on-line detection device is provided.
