diagnosis and ANALYSIS OF LARGE CONTACT INTERMEDIATE RESISTANCES for providing fire safety  of ELECTRICAL CONTACT CONNECTIONS

The article focuses on analysis of application features of means for thermal monitoring for diagnostics of electric contacts overheating. Analysis results are systematized for identifying signs of such a fire-prone process as occurrence of large contact intermediate resistances. It is proved the possibility of application of overheating indicators based on thermo-bimetallic sensitive elements. Thermo-bimetallic indicators are used for the detection of defective electrical contacts during holding preventive measures dedicated to electric service.
