Study On The Installation Technology Of Outdoor Open Equipment For High Voltage Substation

Ultrahigh pressure engineering is the power transmission technology developed by the state in recent years,which promotes the rapid development of power industry in China.But,ultra-high voltage involves a lot of technological innovation,which has no experience to learn from.Jingdong 1000 kV Ultrahigh pressure engineering and XiMeng ± 800 kV project is the background,It combined with the actual construction and design of the uhv equipment installation noise reduction measures,shockproof measures such as installation technology.It is of great practical significance for China’s ultra-high pressure constructionThe thesis summarizes the installation technical data of the high voltage substation.It has studied the installation technology of outdoor open equipment for high voltage substation under combining construction of ultra-high voltage project.It mainly includes:(1)This thesis analyzes the noise of high voltage equipment in Jingdong 1000 kV Ultrahigh pressure engineering and XiMeng±800 kV project.It studies noise control measures.The thesis summarizes the countermeasures and solutions of noise reduction.High voltage equipment is large,High voltage,High noise and It is difficult to reduce noise.It requires a greater investment in human and material resources.(2)In this thesis,the anti-vibration measures and the earthquake resistance level are investigated.And it summarizes the anti-earthquake measures of dongte high-pressure engineering in Jingdong 1000 kV Ultrahigh pressure engineering.High voltage equipment is large,High voltage,High noise and It is difficult to reduce noise,the transformer is huge,the Surge arrester and the Potential transformer is higher than the Ordinary substation.It lets she equipment have Long bodied and higer The center of gravity.The thesis is looking for a way,It is easy to install the shock absorber system during construction and It is easier to maintain during runtime.(3)The thesis analyze the requirements of high voltage equipment for installation,The Jingdong 1000 kV Ultrahigh pressure engineering is the research object,compared with the installation of other common equipment.This thesis summarizes the installation technical scheme of outdoor open equipment for high voltage substation in the end.It proposed the construction method of optimizing the casing installation and vacuum of the reactor through the equipment installation process.It provides experience and methods for the construction of the extra high voltage station in China.In Jingdong 1000 kV Ultrahigh pressure engineering,The installation environment of the equipment is high.The staff works at the construction sitemake a mobile enclosed dedusting plant.This method improves the equipment installation speed and improves the installation quality of the equipmentThe work is of great practical value to the experience summarization of the installation of outdoor open equipment and the improvement of technology.
