嵌入局放探测器的252kV盆式绝缘子可靠性评估

Dependable Evaluation of 252 kV Spacer Embedded with Partial Discharge Detector

文中首先完成了252 kV盆式绝缘子嵌入局放探测器后的模型构建,然后基于ANSYS软件的静电场分析模块和受力分析模块完成了含和不含局放探测器的2种252 kV盆式绝缘子的电场计算分析和受力分析。通过计算分析比较,能够确认252 kV盆式绝缘子嵌入局放探测器后,其电场分布较未加金属探测器时更加均匀,而其受力也在许可范围内。因此,252 kV盆式绝缘子中嵌入局放探测器是可行的。

Firstly, the paper accomplished the modeling of 252 kV spacer embedded with partial discharge detector. Then, the electric field distributions and stress distributions of the two different types of spacers, i.e. embedded with and without the partial discharge detector, were also depicted, based on the static electric field and stress analyzing modules. After analysis and comparison, it reveals that the electric field distribution is more uniform, and its force is also within the allowance, after the 252 kV spacer was embedded with partial discharge detector. In conclusion, it is applicable to embed partial discharge detector in 252 kV spacer.
