There are residential areas around the converter station,and the population density is relatively large.In order to promote the smooth implementation of the project and reduce the impact of converter station on the surrounding environment,as one of the noise sources and main equipmentof converter station,how to layout and what kind of outlet method for flexible HVDC transformers are the key issues to be studied.Based on the typical outlet and layout scheme of converter station in operation,and combined with the specific layout requirements of converter station,six outlet schemes of flexible HVDC transformer using oil-gas bushing or air bushing,and different combinations of outlet direction are given,and the advantages and disadvantages of each outlet scheme are analyzed.Different outlet schemes are compared from the convenience of test and replacement of standby phase,the maturity of outlet structure,the feasibility of space arrangement in the station,and the restriction of outlet method etc.It is suggested that the outlet structure with the same side of the long axis is adopted for the converter station,that is,transformer adopts the arrangement scheme that both the valve side and the grid side are air bushing and the same direction is out of the side,which is convenient for testing,operation and maintenance,saves the layout size in the station,and can adapt to the different grid side into the line.
