DEVICE ice melting on wires POWER LINES

摘要

The invention relates to the field of electrical appliances and a converter and can be used in stationary and mobile applications for melting ice on the wires of power lines (VL).; Technical result of utility model - a reduction of melting ice at the time the three-phase power line and reduced power consumption required for ice melting on all three wires.; The apparatus comprises a source (1) constant current with an output capacitor (2), three-phase bridge inverter (3) on a fully controlled rectifiers (4), (5), (6), (7), (8), (9) and a three-phase a bridge rectifier (10) connected to the source (1) DC, according to (anode terminals to the "plus" a source (1)) and the counter, respectively, wherein the three phase terminals (11), (12), (13) a rectifier and three phase terminals (14) (15) (16) connected to the converter and intended for connection to wires (17), (18), (19) transmission line, closed at the distal end. In the steady mode, the control system (20) generates a series of pulses, providing alternating ON state of three of six fully controlled valves (4) - (9) at each half-period of the working frequency. 1 yl.
