PULSE ELECTROTHERMAL DEICER FOR POWER CABLES

摘要

A system for deicing a power cable includes a power cable having an inner conductor (302) and a metal shell (304) separated from the inner conductor (302) by a dielectric material (306); and a switch module (309) that can divert power from the inner conductor (302) to the metal shell (304), generating heat to melt ice on the power cable. A method for deicing a power cable having an inner conductor (302) and a metal shell (304) includes generating a control signal indicating ice on the power cable, and diverting power from the inner conductor to the metal shell to generate heat to melt ice on the power cable. A method for preventing ice formation on a power cable includes providing a power cable having an inner conductor (302) and a metal shell (304), and periodically diverting power from the inner conductor to the metal shell to generate heat to prevent the ice formation.
