Automated system for determining heat lossesof the educational audience. Hardware part

The article discusses the structure of the hardware and internetworking of automated room heat loss identification system on example of the Ugra State University classroom. The temperature controller has been developed taking into account the specifics of the room. A heat meter with telemetry capability has been selected.

Development of Wireless Heat Variation Detection System between MCCBs and MCs within an MCC

In this study, we developed a wireless heat variation detection system that can measure the temperature difference between the molded case circuit breaker (MCCB) and magnetic contactor (MC) of the motor control center (MCC), collect data, and monitor the heat variation of the MCC connection. Thus far, we have developed a temperature controller and applied a multi-communication technique based on Bluetooth Low Energy between the repeater and temperature controller between the MCCB and MC. Furthermore, we designed the measured temperature data to be transmitted to the cloud server via a gateway. To verify the functionality and performance of the developed wireless heat variation detection system, we initially installed 1 gateway for communication with the MCC server, 4 sets of 4 types of temperature controllers in Repeater 1, 12 sets of 4 types of temperature controllers in Repeater 2, and 6 sets of 4 types of temperature controllers in Repeater 3. Then, we conducted an experiment to periodically monitor the temperature at 12 locations of the MCCB and MC terminal connections in real-time. This developed device can be applied not only to the MCC but also to the power distribution system using the MCCB and MC. This will contribute to the prevention and management of electrical fire accidents caused by heat variation that can occur because of poor contact, overcurrent, and abnormal current.
