喷射式熔断器是将熔体装在由固体产气材料制成的绝缘管内。固体产气材料可采用电工反白纸板或有机玻璃材料等。当短路电流通过熔体时,熔体随即熔断产生电弧,高温电弧使固体产气材料迅速分解产生大量高压气体,从而将电离的喷射式熔断器全绝缘设计,提高配网绝緣程度,降低事故发生率.尤其是城市配网,完全解决了传统跌落式熔断器的裸露点:封闭型结构避免了内部触头受污损引起接触电阻增加的问题。保证设备电气性能的有效性、并避免了熔断器因污损引起的绝缘电阻下降问题。
喷射式熔断器是利用金属导体作为熔体串联于电路中,当过载或短路电流通过熔体时,因其自身发热而熔断,从而分断电路的一种电器。熔断器结构简单,使用方便,广泛用于电力系统、各种电工设备和家用电器中作为保护器件。
