ELECTRICAL LINE PROTECTION DEVICE Russian patent published in 2021 - IPC H02H3/08 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering for multi-factor protection of electrical wires from fire, including for the reason of poor electrical contact. According to the invention, a driving sensing element (2) is installed on a section of an electric line at the entrance to the electrical panel, and a driven sensing element (4) is installed at the point of connection of the load (5) in the socket or outlet box. The driven sensing element (4) measures the voltage and transmits data to the driving sensing element (2). In the controller of the driving sensing element, the voltage drop between the driving (2) and the driven (4) sensor elements in the line for such a current strength is determined. If the voltage drop is greater than the permissible one, then the line is disconnected from the load (5) through the actuating element (1), since overheating of the conductor is detected, in a place with a bad contact.

EFFECT: expansion of the arsenal of technical means.
