Problems solved by technology
The advantage of the optical fiber temperature measurement method is that it is not disturbed by the electromagnetic field and the environment, but the optical fiber temperature measurement sensor must be directly installed on the surface of the object to be measured for temperature measurement, which will not only affect the insulation performance of the equipment, but also cause flashover along the surface
The advantage of the infrared radiation temperature measurement method is that it is a non-contact temperature measurement method without touching the measured target, but the infrared radiation temperature measurement system often has an electronic unit, which is susceptible to electromagnetic field and environmental interference, and the temperature measurement distance, angle, temperature measurement Target emissivity, etc. will affect infrared temperature measurement

Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0032] The realization principle of the present invention is firstly introduced below.
[0033] GIS equipment bus temperature measurement has some particularities, one is that the heat source has high voltage; 6The gas is sealed in the tank, so its measurement environment is very harsh. The high current and strong sealing of gas insulated switchgear will cause a sharp rise in bus temperature, which will lead to GIS failure, which will affect the operation safety of the entire power grid.
[0034] Since the surface acoustic wave sensor is completely passive and can detect and read the sensor signal wirelessly, it can work in the high voltage, insulated and sealed environment of the GIS bus. More importantly, the surface ...

The invention discloses a surface acoustic wave temperature monitoring system suitable for a gas insulated switch cabinet, which includes a surface acoustic wave radio frequency detection radar and a surface acoustic wave sensor, wherein the surface acoustic wave radio frequency detection radar is used for generating and emitting the electromagnetic signals for detection, detecting the electromagnetic signals with the temperature information emitted back from the surface acoustic wave sensor, and digital signal processing the electromagnetic signals with the temperature information, so as to obtain the temperature information; and the surface acoustic wave sensor is used for converting the electromagnetic signals received by the sensor antenna into surface acoustic wave signals, converting the surface acoustic wave signals with temperature information reflected by the reflecting grating into electromagnetic signals, and emitting the electromagnetic signals. By adopting the surface acoustic wave temperature monitoring system, the precise measurement and real-time monitoring alarm on the temperature of the gas insulated switch cabinet bus are realized.
Description
technical field [0001] The invention relates to the technical field of power system temperature monitoring, in particular to a surface acoustic wave temperature monitoring system suitable for a gas insulated switchgear (GIS). Background technique [0002] Electricity is an important driving force and guarantee for economic and social development. Gas insulated switchgear (GIS) is an important power equipment for the collection, distribution and transmission of electric energy. As an epoch-making product of electric power development, it will definitely replace other backward switchgear in the near future, but the GIS status monitoring method has not yet been perfected. , Failures due to overheating occur from time to time. As an important means of power system fault diagnosis, temperature monitoring will provide further guarantee for the normal operation of GIS equipment if it can be used in the condition monitoring of GIS equipment. [0003] At present, there are mainly t...
