HIGH-VOLTAGE NETWORK AND PROCEDURE FOR MELTING GLASED FROST ON WIRES OF OVERHEAD TRANSMISSION LINE Russian patent published in 2010 - IPC H02G7/16 

FIELD: power engineering.

SUBSTANCE: high-voltage network consists of break into n-constituent and stretched between pylons phase wires of the HVL and of facility for glased frost melting (FGFM) on these wires. The invention is notable with the FGFM inclusion into break of each phase wire of the HVL and is made with three induction coils positioned on a common steel core. One of the coils is in series coupled with the wire and shunted to a switch unit, while each of the other two coils is coupled back-to-back to one another and in series between the first coil and one of groups of n/2 constituents. Also both n/2 groups are separated from each other along length of an anchor span of the HVL with insulating spacers. According to another version the technical result, i.e. procedure for melting glased frost in a high voltage line, is achieved like follows: as glased frost grows, electric current of the FGFM is transmitted through n-constituents under bigger compared to standard in the HVL load. Also alternate electric current of standard load of the HVL is re-distributed between groups of n/2 constituents by breaking the unit switching the first coil of the FGFM.

EFFECT: raised efficiency.
