DEVICE FOR REMOVING SNOW AND ICE COVER FROM CONDUCTORS OF POWER TRANSMISSION LINES Russian patent published in 2013 - IPC H02G7/16 

FIELD: electricity.

SUBSTANCE: device includes identical galvanically isolated generators of high-power current pulses 1, the number of which corresponds to the number of controlled PTL. Each generator is separately connected to split-phase conductors of the corresponding controlled PTL sections. Device also includes monitoring devices 2 installed along PTL on supports of power transmission lines. Each of the glaze ice hazard monitoring and warning devices 2 includes glaze ice loads sensor 3 (GLS), digital code shaper 4, controller 5 for conversion of a digital code to time interval as per pulse-time modulation (PTM) rule, self-contained power supply unit 6, radio transmitter 7 for transmission via a radio channel to the dispatch station of warning and control commands of PTL protection system against glaze ice formations. Device also includes electric substation 8 including generators of high-power current pulses 1 as per the number of controlled PTL; radio receiving devices 9 (RPU-l-RPU-n) as per the number of high-power current pulse generators for receiving from monitoring devices 2 of signals with commands for automatic actuation of PTL protection system against glaze ice formations, dispatcher workstation 10 and illuminated panel 11 with PTL monitoring data and taken safety measures.

EFFECT: invention provides effective PTL protection against glaze ice formations.
