DEVICE FOR SAFETY DISCONNECTION OF CABLE-ROPE OF TETHERED UNMANNED AERIAL VEHICLE Russian patent published in 2024 - IPC H01R4/66 

FIELD: electric protective equipment.

SUBSTANCE: device comprises a circuit of electrical connections, as well as a toroidal current transformer with two oppositely wound primary windings and one secondary winding. Switching equipment is made in the form of a starting element and an actuator, wherein one of the phase wires of the multiphase electric circuit is connected to the first input terminal of the voltage converter through the first power contact of the actuator, the first primary winding of the toroidal transformer and the first core of the cable-rope. Second input terminal of the voltage converter is connected to the neutral of the multiphase electric circuit through the second core of the cable-rope, the second primary winding of the toroidal transformer and the second power contact of the actuator. Secondary winding of the toroidal transformer is connected to the input of the starting element of the switching equipment.

EFFECT: simplified process of protective shutdown of damaged section of electric power supply circuit of tethered unmanned aerial vehicle.
