摘要
网侧出线装置绝缘结构是换流变压器整体绝缘结构中的重要组成部分,该结构的可靠与否直接决定换流变压器的运行安全性。与网侧接入较低电压水平的换流变压器相比,高电压等级的网侧出线装置结构更加复杂。在网侧接入500 kV换流变压器网侧出线装置的基础上,优化设计网侧接入750 kV换流变压器网侧出线装置,并采用电场仿真软件对其电场进行分析,计算其各部分电场分布和安全裕度,分析其安全性。
Line-side outlet device is an important part of a converter transformer,and the safe operation of the converter transformer is directly determined by the reliability of insulation system of the line-side outlet device.Compared with the converter transformer with lower voltage on line-side, high voltage line-side outlet structure is more complex.Based on the line- side outlet structure of the line-side 500 kV converter transformer, the line-side outlet structure of the line-side 750 kV converter transformer is optimized,and the electric field distribution and the safety margin are calculated using electric field simulation software.Finally the safety of the structure is analyzed.
