FIELD: electricity.
SUBSTANCE: glase-ice accretion signalling device includes transmitting device, housing made in the form of coupling from conducting thermal diamagnetic material, which is put on line conductor, n ferromagnetic clamp-shaped plates rigidly fixed on the housing at design distance from each other and with rotation through an angle of 360°/n, microphones, power supply, connection wires by means of which microphones and transmitting device is connected to power supply. At that, ferromagnetic clamp-shaped plates have inserts from soft magnetic material with lower saturation induction. As per the second version, glase-ice accretion signalling device includes transmitting device and n ferromagnetic clamp-shaped plates; on each plate there is additional measuring winding.
EFFECT: improving signalling reliability and enlarging functional capabilities.
