电子式互感器技术发展趋势分析

Probe into the Technology Tends in Electronic Transformers Region

介绍了几种新型电子式电流互感器和电子式电压互感器的技术原理和产品特点,指出了电流、电压互感器技术领域的发展趋势,认为在今后10年内传统的电流、电压互感器或将退出市场。建议传统互感器制造厂应适应电网智能化的要求,积极研究低功率电流互感器和低功耗电容式电压互感器,优化结构,降低成本,提高竞争力;有实力的企业应适时进入电子式电流和电压互感器技术领域,以免被淘汰出局。

This paper introduces the technical principle and product characteristics of a variety of new-type electronic current/voltage transformers, discusses the development tendency of CT and PT, and gives a complete commentary that traditional current/voltage transformers may be eliminated after ten years. This paper is points out that the manufacturers of traditional transformers should focus on low power current transformers and low power capacitor voltage transformers to meet the demands of smart grid, reduce volume of products and cost to boost competitiveness.
