【应用】快熔型陶瓷管保险丝在热水器上的应用
燃气热水器因体积小、快速供应热水、操作方便,而深受广大消费者的喜爱。随着技术的进步,燃气热水器的控制面板也从机械式控制改为电子式控制。电子控制面板可以通过电池供电或者市电直接取电。市电直接取电方式可以免除经常更换电池的烦恼,得到广泛运用。由于市电220V电压在短路等情况下容易对电子器件造成破坏,甚至会产生触电的危险,所以在市电引入端增加过流保护措施是非常必要的。
图1:燃气热水器结构示意图
使用保险丝是最简单、最经济的过流保护措施。选择保险丝应考虑以下6点:
1)正常工作电流。 根据图1所示,热水器用电主要设备有风机、传感器、点火器、自动调节器、显示面板、微电脑控制系统。功率最大一般不超过40W。
2)施加在保险丝上的外加电压。220V市电输入,一般选择250V额定工作电压的保险丝。
3)允许不正常电流存在的最短和最长时间。由于热水器关系到人生安全,所以需要选择快速熔断型保险丝。
4)保险丝的环境温度。
5)安装结构的尺寸限制。
6)要求的认证机构。
在这里向大家推荐一款由LITTELFUSE(力特)公司推出的216系列快熔型陶瓷管保险丝,符合IEC规范,非常适合燃气热水器过流保护。该系列保险丝采用5x20mm标准小型化封装,减小空间占用,并且与其他厂家同封装产品兼容。-55℃~125℃工作温度范围,完全满足热水器苛刻的工作条件。0.05A至16A多达25个额定电流规格可供选择。在4倍额定电流下熔断时间最大为0.3秒,熔断时间快,安全保障。并已通过中国CCC认证、UR认证、加拿大CSA认证、瑞典SEMKO认证、德国VDE认证以及欧盟CE认证。保险丝套管采用陶瓷管,相较于玻璃管,陶瓷管具有防爆裂,耐高温等优点。型号0216.200MXP陶瓷管式保险丝,有着200mA额定电流,是热水器过流保护设计的首选。

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。
