摘要

特高压电器设计的核心问题之一便是绝缘结构设计。绝缘结构设计能否满足要求

对产品的安全运行至关重要。为此

笔者对1 000 kV SF6气体绝缘标准电压互感器进行了电场有限元分析

通过对多组结果的比较

提出1 000 kV SF6高压电器绝缘设计的要点

并对其他类似结构的特高压电器设计提出了一些浅见。研究发现:对于SF6高压电器产品

改善套管电位分布、降低电场强度的有效方法是设置分压屏蔽

通过合理选择分压比K、加大曲率半径或采用多曲率弧线等方法降低最大电场强度;对类似结构的1 000 kV SF6气体绝缘特高压电器

可利用电容分压原理进行绝缘设计

必要时可设置两个或两个以上分压屏蔽

但分压屏蔽数量的增加会给加工、装配等带来很大难度

需要合理取舍。

Abstract

Insulation structure design is one of the core issues in UHV electrical design

and is essential to the safe operation of products.This paper calculated and analyzed the electric field intensity of 1 000 kV SF6 gas insulated voltage transformer via finite element method.Several groups of results were compared

and some key points were proposed for the high voltage electric device insulation design and other ultra high voltage electric device design with similar structure.It is found that for high voltage apparatus of SF6

the effective measures to improve casing potential distribution and reduce electric field intensity are setting up shielding pressure

and reducing the maximum electric field intensity by means of choosing reasonable compression ratio K

increasing curvature radius or using multi-curvature arc

etc.For other 1 000 kV SF6 gas insulated UHV appliances with similar structure

capacitive voltage dividing principle can be applied to their insulation design

and two or more shielding pressure can be set up when necessary.However

the increasing number of shielding pressure will bring great difficulty to processing and assembling

therefore the number should be reasonable.
