保护电压互感器用全范围限流熔断器的研究
摘要
介绍了一种用于保护电压互感器的新型全范围限流熔断器
其外壳采用由玻璃纤维丝和石英玻璃管组成的复合管体
采用耐高温的石英玻璃棒取代常规的陶瓷材料作熔体骨架
利用硅橡胶管的产气特性来完成低过载电流开断的要求。各种试验数据及特性曲线表明该熔断器性能优异
Abstract
In this paper
a new full range fuse for protection of potential transformer is introduced. It includes a compound envelope consisting of a quartz glass tube with compound glass fiber
a heat resisting quartz glass rod instead of conventional porcelain for the support of fuse element and silicone rubber tube used as low current arc quenching material under lower over load conditions. The experimental characteristics and the type test results has shown the superiority of the new fuse.
