摘要

2023年欧洲议会通过提议2031年开始不再使用145 kV以上含氟气体开关设备，开发合成空气绝缘的环保型电压互感器，以减少温室气体排放并应对电力市场的发展需求。合成空气的绝缘性能较SF

绝缘性能较差，0.8 MPa压缩空气绝缘强度仅为0.4 MPa SF

绝缘强度的约50%。合成空气绝缘性能差造成电压互感器绝缘性能差、绕组尺寸大、漏电抗高等一系列问题。文中介绍了菱格薄膜在空气下的绝缘仿真及性能测试方法，绕组尺寸优化、整体结构电场仿真及优化设计，220 kV合成空气电压互感器顺利通过了雷电冲击、操作冲击、温升、精度测试（0.2级）。合成空气电压互感器的成功研制，实现了产品的环保型设计，为新时代低碳发展提供了技术支撑。

Abstract

In 2023

the European Parliament passed a proposal to phase out the use of fluorinated gas switchgear above 145 kV starting from 2031

and to develop environmentally friendly voltage transformers using synthetic air insulation so as to reduce greenhouse gas emissions and meet the development needs of the electricity market. The insulating performance of synthetic air is significantly inferior to that of sulfur hexafluoride

with the dielectric strength of 0.8 MPa compressed air being only 50% of that of 0.4 MPa sulfur hexafluoride. The weak insulating performance of synthetic air leads to such series of issues as weak insulation performance of voltage transformers

large coil dimensions and high leakage reactance. In this paper the insulation simulation and performance testing methods of diamond -grid film in air

coil dimension optimization

overall structural electric field simulation

and optimized design are introduced. The 220 kV synthetic air voltage transformer successfully passed lightning impulse

switching impulse

temperature rise and accuracy(class 0.2)tests. The successful development of the synthetic air voltage transformer has achieved an environmentally friendly design for the product and provided equipment support for low-carbon development in the new era.
