聚合物自恢复熔丝与传统熔断器和其他电路保护装置的区别在哪里？带过载装置的聚合物自恢复熔断器如何保护电路？聚合物自恢复熔断器与普通熔断器最明显的区别是其自恢复特性。虽然两者都能提供过电流保护，但是聚合物自恢复熔断器可以提供大量过电流保护和普通熔断器一次熔断器，并且必须被替换以使电路正常工作。emi／emcisalehtp://salimil.com/modem聚合物自恢复保险丝的性能与延时熔断器有些相似，两者都需要考虑其自身的散热，但聚合物自恢复熔丝不会根据i2t加热延时熔断器。硒聚合物是自恢复的。保险丝一开始就坏了。聚合物自恢复熔丝与双金属片的差异不是自恢复性。双金属片在故障依然存在时可自行恢复。当它动作时，它产生较大的电压并恢复可能损坏设备的故障。聚合物自恢复保险丝将保持在高电阻状态，直到故障被移除。问答区/理解emi／emcisalehtp://salimil.com/模式聚合物自恢复保险丝和陶瓷自恢复熔丝之间的差异是它们的初始电阻、反应时间和失效大小。两者都是自修复的，但聚合物自恢复保险丝的移动速度比陶瓷自恢复保险丝具有相同的保持电流。聚合物自恢复熔断器和可加载超压装置的组合通常应用于通信领域。对于许多故障事件，晶闸管、气体放电管或二极管可以为过载装置提供保护。聚合物自恢复熔断器可以在某些故障事件中保护这些过电压保护装置。当然，聚合物自恢复熔断器也可以提供过电流保护。（symel半导体tel：4001801665/qq：2885530686/2885295916）您的电路保护专家 [url=http://www.salimil.com]深圳EMC实验室[/url] [url=http://www.xp269.net/home.php?mod=spacecp&ac=plugin&id=jzsjiale_sms:home]聚合物自恢复保险丝与普通保险丝以及其它电路保护装置的区别在哪里？聚合物自恢复保险丝怎样与可承载过压装置一起保护电路？[/url] [url=http://www.xp269.net/home.php?mod=spacecp&ac=plugin&id=jzsjiale_sms:home]聚合物自恢复保险丝与普通保险丝以及其它电路保护装置的区别在哪里？聚合物自恢复保险丝怎样与可承载过压装置一起保护电路？[/url]
