FIELD: electricity.SUBSTANCE: invention relates to the equipment for systems of protection of underground and underwater pipelines from corrosion. The device contains a power supply connected through cables to a section of the protected pipeline and with anode grounding conductor, and it contains a control unit connected through the control unit to a power supply designed as an EMF source, it is combined with a section of the protected pipeline and comprises two half rings with longitudinal ribs and fitted with longitudinal flanges with fixing holes made from hydro-resistant dielectric material with high heat conductivity, covering the section of the protected pipeline, and inside the longitudinal ribs along the whole their length zigzag rows of thermal-electric sections are placed, consisting of connected among themselves thermal emission converters, consisting of a pair of pieces, made from different metals the ends of which are flattened out and tightly pressed to each other and are located in the heating and cooling zone near the edge of longitudinal ribs and surface of the pipeline section parallel to their surface, and free ends of sections of each rib from one side are connected through terminals with homonymous charges with the control unit, from the opposite side through collectors, terminals with heteronymous opposite charges and connecting cable with anode grounding conductor.EFFECT: improvement of device reliability and efficiency.8 dwg |
