在智能工业时代,工业以太网、智能传感器网络、无线通信网络、工业计算机等技术的应用,使工业系统架构变得日益复杂,如何保证每个模块甚至每个元件安全高效地发挥性能已成为智能工业发展道路中无法回避的问题。

 

在电路保护领域,过压、过流、过功率、电源畸变、雷击浪涌,都会对电路甚至是整个工业系统造成破坏,所以要保证工业系统安全高效的运行,首先就要选择功能强劲的保护产品,为工业保驾护航。作为全球第一的电源保护品牌,力特提供种类多、应用广的保护器件,包括从保险丝、晶闸管、瞬态抑制二极管等被动元件,其完整的产品线,为工业应用建立起一堵巨大的“防火墙”。

科技的发展日新月异,变频器保护产品也要根据市场的要求做出改变。Littelfuse在变频器保护领域不仅铺就了一条完整的产品线,同时在已有的产品中不断推出新品,以应对时代的挑战。变频器产业非常火热,Littelfuse的392系列保险丝器件,为变频器设备提供瞬变过压保护。392系列器件支持的电流范围为800mA~6.3A,能提供可靠的浪涌电流处理能力,有效保护变频器设备。不论是在消费类电子产品,还是在工业设备中,Littelfuse的保护器件都是不可或缺的重要元件,它保护了客户的装置与商业资产,免其受到电路损害所带来的损失。

变频器主回路使用保护电路

图2:变频器主回路使用保护电路

 

变频器主回路主要由整流电路、限流电路、滤波电路、制动电路、逆变电路和检测取样电路部分组成。如上图2所示,在主回路的输入端和输出端都会使用保护电路,当变频器出现异常时,为了使变频器因异常造成的损失减少到最小,甚至减少到零。每个品牌的变频器都很重视保护功能,都设法增加保护功能,提高保护功能的有效性。

 

变频器使用中的过电压现象是最为常见的。过电压产生后,变频器为了防止内部电路损坏,其过电压保护功能将动作,使变频器停止运行,导致设备无法正常工作。因此必须采取措施消除过电压,防止故障的发生。在变频器的电源模块输入端加入力特的保险丝器件,做过流保护,是一种非常有效的保护方法。

【元件】LITTELFUSE推出行业首创超大电流SMD保险丝系列,提供150A和200A额定电流规格

LITTELFUSE近日宣布推出871系列超大电流SMD保险丝,这一创新系列是对881系列的补充,提供150A和200A保险丝额定电流,是对881系列125A最大额定电流的重大升级。871保险丝系列为电子设计人员提供单保险丝、表面安装解决方案,无需并联保险丝配置。

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。

【技术】Littelfuse解析保险丝及其应用注意事项

保险丝作为过流保护器件,在电子行业得到普遍应用,存在感非常强,却又那么不起眼,只要不是全新的设计方案,只要没出问题,经验的沿用以至于很多硬件工程师对于保险丝的参数与选型不明所以。Littelfuse浅显易懂地讲述保险丝及其应用注意事项,供有需人士参考。

Littelfuse 保险丝 ,规格书中维持电流ihold是什么意思?触发电流itrip是什么意思?请阐述详细电流先后保险丝的工作状况,请教专业

保险丝的Ihold 就是保持电流,也就是工作电流,一般标明的多少A,在该电流下工作,保险丝不会动作。Itrip就是触发电流,熔断电流, 一般为保持电流的两倍,达到该电流,保险丝会快速动作。Ihold和Itrip之间的电流,会引起保险丝发热,如果散热条件差,引起热量累计,也可能导致保险丝动作。Ihold和Itrip的值和温度有关系,温度越高,Ihold越小。
