高电压互感器技术的发展趋势

Trends of High-Voltage Transformer Development

介绍了几种新型的电子式电流、电压互感器的技术原理和产品特点,阐述了电流、电压互感器技术领域的发展趋势,指出在今后的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企业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率电容式电压互感器,缩小体积,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、电压互感器技术领域,以免被淘汰出局。

Principles and characteristics of several new current and voltage transformers are described, and the development tendency discussed. In the next ten years, traditional current/ voltage transformers will get out of the market. It is suggested that manufacturers of traditional transformers focus on low power current transformers and low power capacitor voltage transform- ers to meet the demands of smart grid, and reduce their product volume and lower the costs for better competitiveness to avoid elimination.
