INDUCTION-RESISTIVE ELECTRIC HEATING SYSTEM Russian patent published in 2018 - IPC H05B6/06 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the various objects electrical heating technique by the heat tracing equipment from ferromagnetic materials. Induction-resistive electrical heating system comprises source of AC voltage, switching device, control and protections unit, temperature sensor, heat tracing equipment made of ferromagnetic material (5), enabling the heat tracing equipment metal bonding connectors, insulated relative to the heat tracing equipment inductor (7) with shield (8) of one of the strands or groups of strands (14, 15) with insulation, inductor construction lengths connectors, junction box, lead-in box, terminal box, input power box (13), electrical values measuring unit. Inductor is a multicore cable, intended both for the inductor electromagnetic field generation, inducing eddy currents in the heat tracing equipment, and to ensure the reverse current flow to the power source.

EFFECT: technical result is provision of the branched pipeline systems with complex geometry heating.
