摘要

本文以碳纳米管(CNT)纤维为材料制备了一种适用于1 A以下低额定电流和4ms高速工作的微型保险丝。采用通用模块熔断器(UMF)的形式制作碳纳米管熔断器，通过增加碳纳米管螺纹定义不同直径的碳纳米管纤维。测量了碳纳米管熔断器的电学性能，如电阻、额定电流和随电流的工作时间。碳纳米管熔断器的电阻随熔断器直径的增大而减小，额定电流随熔断器直径的增大而增大。因此，随着碳纳米管熔断器直径的增加，带电流的操作时间也随之增加。通过增加碳纳米管螺纹，制备的碳纳米管熔断器具有0.05 ~ 1.25 A的宽额定电流范围。操作时间约为3.6ms，适用于UMF。

Limited Current Characteristics of Carbon Nanotube Elements Miniature Fuses

In this paper, we prepared miniature fuse fabricated with carbon nanotube (CNT) fiber for the use of low rated current under 1 A and high speed operation under 4ms. CNT fuses were fabricated in the form of universal modular fuse (UMF) with different diameter of CNT fibers defined by multiplying the CNT threads. Electrical properties of the CNT fuses were measured such as resistance, rated current, and operation time with current. Resistance of the CNT fuse decreased and rated current increased with the diameter of the CNT fuses, respectively. Consequently, the operation time with current increased with the diameter of the CNT fuses. The CNT fuses fabricated in this work had broad range of low rated current from 0.05 to 1.25 A by multiplying the CNT threads. Operation time was measured about 3.6ms which was applicable to the UMF.
