Abstract


Recent years, UHV transmission rapid development , has played an important role in the optimization of the grid structure , the development of UHV has brought a series of problems , from a technical point of view of the surface electric field intensity of transmission lines is one of many factors . Of the original transmission line method of surface electric field strength , the finite element method is selected as the research method . By calculating the UHV AC and DC line , DC Hybrid frame line conductor surface field strength , the the analysis line the surface of the electric field strength of many influencing factors to obtain the optimal way to wire layout . Another article based on the finite element software ANSYS calculated consider the pattern of stranding surface field strength , a difference of 20% with the wire as a smooth cylinder calculations . This study can provide a reference for the engineering design and construction of transmission lines . Conductor Selection should give full consideration to the impact of stranded maximum field of pattern on the surface of the wire .
