Abstract

This paper deals with the electric field optimization on the spacer of 150 kV Gas Insulated Substation (GIS) using Functionally Gradient Material (FGM). The basic spacer model is made from epoxy resin with permittivity equals 3.5. The dimension of basic spacer and spacer with FGM modification is same. FGM is done by composing 90% of spacer with epoxy resin and 10% of spacer with higher permittivity. Titanium Oxide (TiO2) with relative permittivity 8.4 is chosen as grading material. Therefore, the spacer with FGM consists of epoxy resin with relative permittivity 3.5 and Titanium Oxide (TiO2) with relative permittivity 8.4. The Titanium Oxide material is placed on the top and the bottom of the epoxy resin material. The maximum electric field intensity on 150 kV GIS spacer without modification is 138 kV/cm [17]. The maximum electric field intensity is still below the electric field breakdown of epoxy resin (197 kV/cm) [18]. FGM modification with Titanium Oxide (TiO2) layer reduces the maximum electric field on spacer to 56 kV/cm.

利用功能梯度材料优化150 kV GIS隔层的电场

本文研究了利用功能梯度材料对150kv气体绝缘变电站隔层进行电场优化的方法。基本隔离模型由介电常数为3.5的环氧树脂制成。基本垫片与经FGM修饰的垫片尺寸相同。FGM是由90%的环氧树脂隔离剂和10%的高介电常数隔离剂组成的。选择相对介电常数为8.4的氧化钛(TiO2)作为级配材料。因此，FGM隔离剂由相对介电常数为3.5的环氧树脂和相对介电常数为8.4的氧化钛(TiO2)组成。环氧树脂材料的顶部和底部分别放置氧化钛材料。未经改造的150 kV GIS隔震片上最大电场强度为138 kV/cm[17]。最大电场强度仍低于环氧树脂的电场击穿(197 kV/cm)[18]。用氧化钛(TiO2)层对FGM进行改性，使间隔片上的最大电场降至56 kV/cm。
