为您揭秘:熔断器是保险丝吗?
什么是保险丝?19世纪80年代,自爱迪生试用了6000多种材料,试验了7000多次改良了灯泡的灯丝,发明了保险丝用于保护当时昂贵的白炽灯;同时也开启了保险丝的发展。而熔断器是一种重要的电气设备,它在电路中发挥了保护作用,那么熔断器就是保险丝吗?本文将介绍熔断器的基本原理、结构、作用在实际应用中的选择与安装方法。来为大家解决疑惑。
一、熔断器的基本原理
熔断器的基本原理是利用热效应或电磁效应,在电流超过额定值时迅速断开电路,防止过电流对电器设备造成损害。 那么熔断器具有什么保护作用?起过流保护的作用,在电路中,电流较大时,容易短路没有及时将电路切断,会导致设备烧毁。有了熔断器就能够达到切断电路的效果。
二、熔断器的结构
熔断器通常由熔丝、外壳和支座组成。 熔丝:是熔断器的核心部件,一般采用合金制成。在电流超载时,熔丝会受到热融化,从而断开电路。 外壳:用于保护熔丝,同时具有绝缘作用,以防止电路短路。 支座:主要作用是使熔管得以固定,让熔断器正常工作。
三、熔断器的作用
熔断器主要承担以下两个方面的作用: 过载保护:当电路中的电流超过熔断器额定电流时,熔丝会瞬间熔化,切断电路,防止过载损坏电器设备; 短路保护:在电路出现短路情况时,熔丝会迅速熔化,阻止电流继续流动,以保护设备和电路。
四、熔断器的选择与安装
在选择熔断器时,需考虑电路的额定电流、额定电压以及设备的特性。同时,熔断器应安装在电路的接口处,以便及时切断电流。 常见的熔断器类型有:
1、RC插入式熔断器;
2、RL螺旋式熔断器;
3、RM无填料封闭管式熔断器;
4、RT有填料封闭管式熔断器;
5、RS快速熔断器。
根据其应用(特性)和分断范围,熔断器可分为多种类型,如下:
安装熔断器的注意事项:
1.安装前,应检查熔断器的额定电压、额定分断能力和额定电流。
2.熔断器应垂直安装。
3.安装时应避免熔体受到机械损伤。
4.安装时周围介质的温度尽可能保持一致,避免产生误差。
5.熔断器的安装位置应便于观察和更换熔体。
从结构方面来看,保险丝是熔断器,但熔断器未必是保险丝。 熔断器作为电路保护的重要组成部分,在现代电气系统中发挥着不可忽视的作用。了解其基本原理、结构以及在实际应用中的选择与安装方法,对保障电路的稳定运行至关重要。

开关电源中,如何选用保险丝的电流?
一是看电路的最大持续工作电流,二是看工作环境温度,三是所选保险丝的认证情况,比如UL认证的保险丝折减率是75%。保险丝的额定电流=电路最大持续工作电流/(温度折减率*保险丝认证折减率),举个例子,电路的最大持续工作电流为2A,工作温度最大为80℃,对应保险丝的温度折减率为88%,UL认证,2A/(0.88*0.75)=3.03A,则所选保险丝的额定电流应大于3.03A。Littelfuse作为保护器件的大品牌,保险丝种类丰富,认证齐全,可以在平台搜索了解详情,有具体需要可以提选型帮助,保险丝不光只看电流的。
