逆变器是把直流电能转变成交流电(一般为220V,50Hz正弦波)的设备。随着便携式设备的广泛使用,逆变器在人们的生活中越来越多的被应用,关于逆变器的安全性能也越来越受到关注,本文介绍了PTC,即自恢复保险丝是如何保护逆变器安全的。


PTC自恢复保险丝

所谓PTC,即自恢复保险丝,是一种过流电子保护元件,采用高分子有机聚合物在高压、高温,硫化反应的条件下,搀加导电粒子材料后,经过特殊的工艺加工而成。传统保险丝过流保护,仅能保护一次,烧断了需更换,而自恢复保险丝具有过流过热保护,自动恢复双重功能。


PTC与传统的熔断器的主要区别是自复式的,而传统的熔断器在跳闸之后需要对其进行更换。在大多数过电流事件发生后,熔断器将会彻底切断电流流动,这种效果在一些关键应用中可能是非常有利的。与此相反,PTC器件会显著增加其电阻,从而形成过电流保护,但依然会允许有涓流通过。


由于PTC器件可以自动复位,许多电路设计人员在可能会因用户造成的故障而导致过电流事件的情况中选择PTC器件。此外,PTC器件也有助于维持较低的保修和服务成本、持续的系统正常运行时间以及用户透明度。在难以接近的或位置偏远的电路中,通常会选用PTC器件,因为在这些条件下熔断器更换很不方便。


PTC在逆变器中的作用

PTC在逆变器产品中的使用方法千变万化,在此我们只对常见情况进行简单说明。

1.保护逆变器电路中所有元器件以及在电路短路或过载时切断电路,防止烧坏电路而使故障进一步扩大或造成火灾事故。

2.在电路短路或过载故障排除之后,PTC会进行自动恢复,使逆变器能够重新工作二不用更换保险丝,可以更好的更方便使用者避免更换保险丝的拆外壳的麻烦。起到更省心,更省力的作用。

3.尤其是安装在设备里面,或者人员比较难以接近区域的逆变器,PTC的应用可以节省很大程度上的维修成本,安全可靠。

4.PTC具有过流和过温的双重保护,更好的保证逆变器的使用寿命。

逆变器产品原理框图

图1:逆变器产品原理框图


如图1所示,LITTELFUSE 1812L系列自恢复保险丝在电路中的的动作原理是一种热能量的动态平衡,当流过1812L系列PTC元件的电流由于1812L系列PTC的关系产生热量,产生的热全部或部分散发到环境中,而没有散发出去的热便会提高PTC元件的温度。正常工作时的温度较低,产生的热和散发的热达到平衡,PTC元件处于低阻状态,PTC不动作。当流过PTC元件的电流增加或环境温度升高,达到产生的热和散发的热的平衡时,PTC仍不动作。当电流或环境温度再提高时,PTC会达到较高的温度。若此时电流或环境温度继续再增加,产生的热量会大于散发出去的热量,使得PTC元件温度骤增,在此阶段,很小的温度变化会造成PTC元件阻值的大幅提高,这时PTC元件处于高阻保护状态,阻抗的增加限制了电流,电流在很短时间内急剧下降,从而保护逆变器电路免受损坏。只要施加的电压所产生的热量足够PTC散发出的热量,处于变化状态下的PTC元件便一直处于动作状态(高阻)。当施加的电压消失时,PTC元件便可以逐渐自动恢复到低阻状态,使电路重新达到平衡。

解析保护电子电气设备免受损坏的不同方法

本文TOPPOWER深入探讨了保护电子电气设备免受损坏的不同方法,包括传统保险丝、创新型电子自恢复保险丝、断路器、金属氧化物压敏电阻(MOV)、电涌保护器、线路滤波器和线路电抗器。

技术探讨    发布时间 : 2024-07-24

自恢复保险丝(PTC)的ITRIP电流的意义是什么?

Itrip可以叫做跳变电流,就是指电流超过该值时,电阻会出现大幅增加。其作为自恢复保险丝特有的重要参数,在设计选型时要格外重视。
