一、概述在SF_6气体中引入旋转电弧作为中等电压的断路技术,改变了SF_6断路器和真空断路器之间论争的长期僵持局面。目前看来,单靠一些技术数据和运行经验,不足以说明哪一种技术存在着明显的优势。两种技术之间的选择更主要的是取决于政策和经济的准则。为了得出结论,有必要对真空和旋转电弧技术作一详细的研究,特别对操作过电压进行分析,最后再从生产方面作经济比较。近15年来,SF_6中压电流分断主要是发展喷气式断路器,利用SF_6气体穿透电弧的
First, an overview of SF_6 gas into the rotating arc as a medium-voltage circuit breaking technology, changing the SF6 circuit breaker and vacuum circuit breaker protracted protracted stalemate situation. At present it seems that depending on some technical data and operating experience, it is not enough to indicate which technology has obvious advantages. The choice between the two technologies is more important than the policy and economic guidelines. In order to reach the conclusion, it is necessary to make a detailed study of the vacuum and rotating arc technology, especially analyzing the over-voltage of operation and finally making economic comparison from the production aspect. The past 15 years, SF_6 medium voltage current breaking is mainly the development of jet circuit breakers, the use of SF_6 gas penetration arc
