Accurate temperature measurement method and apparatus for a cable joint which is based on RF technology

摘要

This invention offers cable joint internal thermometry manner and the device the online which is based on RF technology, the aforementioned device has the internal thermoscope and the external receiver. The internal thermoscope, directly with measuring method of the contact process, measures the cable joint or the temperature of the core wire list aspect, transmits insulating formation with RF identification technology, transmits the data to the external receiver. With that, the external receiver supplied electricity to the internal thermoscope with the RF signal, solved the problem of power supply of the internal thermoscope. Accurate thermometry can do the device of this invention, cubic measure is small, there is a dot which such that applicability is high is superior.
