Title:
TEMPERATURE MEASURING INSTRUMENT, GAS-INSULATED APPARATUS, AND CONDUCTOR TEMPERATURE MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/179055
Kind Code:
A1
Abstract:
A temperature measuring instrument (1) that measures the temperature of a conductor (50) of a gas-insulated instrument is provided with: a housing (11) that is provided with a conductive cylindrical outer frame (11c), in which a first slot antenna (111) and a second slot antenna (112) are formed; and a substrate (12), on which a bandpass element (14) connected to the first slot antenna (111), said bandpass element having a resonant frequency having temperature characteristics, and an isolator (15) connected to the second slot antenna (112) are mounted, and which has a wiring pattern (12a) connecting the bandpass element (14) and the isolator (15) to each other, and is housed in the housing (11). The bandpass element (14) comes into contact with the conductor (50) inserted into the housing (11), and is thermally connected to the conductor.
