SYSTEM FOR AUTOMATIC DETECTION OF OVERHEATING OF ELECTRICAL EQUIPMENT ELEMENTS USING COMPARISON SENSOR, METHOD OF ITS USE AND TESTING Russian patent published in 2024 - IPC G08B17/117 G01N27/407 

FIELD: fire-protection equipment.

SUBSTANCE: systems for detecting emergency and pre-fire situations, namely – systems for automatically detecting overheating of electrical equipment elements, methods of their use and testing. The system for automatically detecting overheating of electrical equipment elements includes gas sensor S_con designed to detect gases released on heating of the controlled element or thermally activated gas-emitting materials installed on it; gas sensor S_com designed to determine the concentration of background gases in the air near the controlled area; a controller configured to connect with at least two gas sensors, including at least one controlling sensor S_con and at least one comparison sensor S_com and generating a notification on overheating and/or transmitting information about such overheating to another device. Also disclosed is a method for testing the said system and a method for using it to automatically detect overheating of electrical equipment elements.

EFFECT: improved reliability and safety of electrical equipment operation due to timely detection of defects accompanied by overheating of electrical equipment elements.
