550 kV SF_6充气套管两种内屏蔽结构的研究
|
摘要
采用Ansys软件计算分析了采用单屏蔽和双屏蔽结构的两种550kV SF_6充气套管的电场分布。分析表明,采用单屏蔽结构的与采用双屏蔽结构的550 kV SF_6充气套管,均符合设计要求。经绝缘试验验证,两种结构设计的套管均通过了试验。但双屏蔽结构的SF_6充气套管,结构较复杂,性价比不及单屏蔽结构的SF_6充气套管。
In this paper, Ansys software is used to calculate and analyze the electric field distribution of two 550 kV SF_6 gas-filled bushing with single shielding and double shielding structure. The analysis shows that the 550 kV SF_6 gas,filled bushing with single shielding structure and double shielding structure both meet the design requirements.The insulation test results show that the bushings with two shielding structural designs have passed the test. However, the SF_6 gas,filled bushing with double shielding structure has complex structure and its cost performance ratio is lower than that of SF_6 gas, filled bushing with single shielding structure.
