Oumaan Technology Group leads the way to new ideas on lightning protection: Highlights of the Hydropower Operation and Inspection ‘Five Small’ Innovation Conference

  On 19th September 2024,the‘five small’innovations of hydropower operation and maintenance were published on site and exchanged in Yichang,Hubei Province.Hydropower operation,maintenance and repair‘five small’innovation is the main method of hydropower operation and inspection staff innovation and efficiency,is to solve problems,improve the quality and efficiency of operation and inspection,the main means of technical management innovation.Small invention,big wisdom,small transformation,big effect,small design,big as,small innovation,big promotion,small suggestion,big value.

  In 2024,the shortlist of‘five small’innovation achievements of hydropower operation,maintenance and repair is 528 items,which are rich in achievements and strong in practicability.528 achievements are the manifestation of the professional ability of hydropower operation and inspection staff and the value of innovation.

  Oumaan Technology Group,as the vice president of the Association,the lightning protection technology service centre for the power industry,attended the meeting,and the Group's General Manager Xu Bochen shared targeted information on the operation and maintenance of hydropower stations from the perspective of lightning protection.

lightning protection technology service centre for the power industry

  By the end of June 2024,China's cumulative installed capacity of hydropower reached 427 million kilowatts,of which 373 million kilowatts of conventional hydropower and 54.39 million kilowatts of pumped storage.The huge installed energy also comes with lightning risks.The flat terrain of the water's edge is easy to become a direct lightning target;the high humidity of the air environment of the hydropower station is easy to form condensation on the surface of the metal devices,surge arresters,insulators,causing electric field distortion,leading to moisture discharge,which can seriously burn the equipment;in the complex natural environment grounding resistance is difficult to meet the needs of the underwater grounding is difficult to meet the standards;the difficulty of accurately locating the lightning accident,which is a major challenge faced by hydropower plant operation and maintenance process.

  In this regard,Oumaan Technology Group proposed four core technologies:for direct lightning disasters,HD-PLR plasma lightning repellent device can achieve no direct lightning in critical areas,widely used in transmission line towers and other scenarios.

  For accidents caused by humidity,such as condensation discharge and flashover of power external insulation,DSAN superhydrophobic and oleophobic coatings can make the surface of the substrate have water-repellent and oil-repellent properties,preventing condensation and other factors prone to triggering electric field aberrations such as condensation on the surfaces of metal parts,insulators and so on.This ensures the stability of operation and maintenance.

flexible grounding technology

  For the grounding device,flexible grounding technology can reduce the grounding resistance of the transmission line tower,reduce the grounding resistance of the substation,inhibit the ground voltage rise caused by lightning strikes,and protect the metal grounding electrode from soil corrosion.Flexible grounding technology can also be applied underwater,to solve the water body corrosion of metal grounding electrode,underwater grounding is difficult to complete and other difficult problems.

  For the problem of monitoring,HD-LDL lightning online monitoring system combines the authority of meteorology,power grid two fields of big data and AI intelligent algorithms,to achieve early warning,accurate positioning,greatly saving the cost of manual investigation.

  Xu Bochen also pointed out that lightning protection is a comprehensive concept,which should be combined with the actual situation and specific needs,targeted design and governance.Should be flash,lead,grounding,surge,anti-surge,anti-dew dirt flash and electrical connection performance are taken into account,from a multi-faceted perspective,rather than simply through the lightning arrester,lightning rods,or a single aspect can be completed.

  Oumaan Technology Group-Heilongjiang Hengdian Lightning Protection Engineering Co.,Ltd.specialises in solving problems such as high grounding resistance,tripping of transmission line lightning strikes,frequent lightning strikes that burn equipment,underwater grounding that can't be completed,and corrosion of metal grounding electrodes by acidic and alkaline soils.

  Oumaan Technology Group can provide services and support such as technical guidance,technical exchange,technical consultation,technical training,engineering transformation,lightning detection,data analysis,programme optimization,operation and maintenance consultant,accident investigation,product development,directed scientific research,standard preparation,resource docking,etc.related to lightning protection.For more information,please call our hotline!
