Abstract

The invention provides a method and a device for on-line measurement on inner temperature of a cable connector based on a radio frequency technology. The device comprises a built-in temperature measurer and an external receiver, wherein the built-in temperature measurer measures the temperature of the cable connector or a core wire surface through a direct-contact measuring method, and transmits data to the external receiver through an insulating layer by a radio frequency identification technology; and simultaneously, the external receiver supplies electric energy for the built-in temperature measurer via radio frequency signals, so that the problem of power supply of the built-in temperature measurer is solved. The device provided by the invention is accurate in temperature measurement, small in volume, strong in applicability and the like.

Description

technical field [0001] The technical invention belongs to the field of electric power detection and is used for measuring the temperature of joints between cables and preventing cable accidents. Background technique [0002] At present, high-voltage transmission lines can be divided into overhead lines and underground cables. However, with the continuous development of urbanization, more and more cities are trying to change the power supply network from overhead lines to underground cables. Since the cable is a concealed project and undertakes a huge task of power transmission, how to ensure the safety and reliability of underground cables has attracted the attention of power supply departments in various cities. [0003] During the construction and installation of underground cables, it is often necessary to connect two sections of cables together. Due to the limitation of the process, contact resistance will inevitably occur. For cables that carry large currents, the exist...
