Intellectualization of the process of measuring the temperature of inaccessible surfaces of electric contact connections

Abstract

The issues of construction are considered and an example of the implementation of the transformation function of an intelligent sensor for the surface temperature of an electrical contact is given. It is shown that the intellectualization of the process of measuring hard-to-reach contact surfaces of the temperature of high-voltage and high-current electrical contact connections is not valid. The term "intelligent" in relation to devices that acquire new qualities due to the processing of the received information in them, is often used in a narrow sense in the presence of the following features: compensation of measurement errors, transmission and processing of the digitized signal of the primary converter. In a broad sense, an "intelligent" sensor, in addition to the above, has the ability to adapt to the signal source and the environment; it is an electronic device that combines sensing elements, signal conversion circuits and microprocessor technology (integration). Application of the principle of the measurement algorithm simplifies the improvement of measurement accuracy by transferring hardware solutions to microcontroller programs. With this deviation of the results, the conversion function of the correction factors is eliminated. This article discusses the construction issues and provides an example of the implementation of the transformation of an intelligent temperature sensor of the contact surface of an electrical contact.
