【应用】自恢复保险丝可用于电源变压器中，可解决好超温、过流的及时保护又不更换保险丝的问题

技术问答

电源变压器是电子产品常用的元件，因其简单、易制而被广泛应用，有升压变压器和降压变压器两类（不含阻抗变换器、线路匹配变压器器），因是将原来的交流电电压按比例升高或降低后输出给负载供电，所以又叫线性变压器，在应用中，升压变压器主要应用于仪器仪表；对于电子产品的电源，实际以降压变压器居多。在结构上，变压器是由迭合的硅钢片与初次级线圈组成。线圈多由漆包铜线绕制，现在也有用漆包铝线绕制的。

对降压变压器而言，其特点是：初级都是220V输入，次级输出都是低压，次级电流小、次级电流大，在工作时都会发热，不同功率、不同线径的变压器其发热程度是不同的。现在的变压器厂家都依据客户的不同用途和不同产品，选择铜线或铝线绕制，容易出现下列问题：在设备工作时发热多的，温度可达70-80°C，但变压器是能工作的，只是漆包线的漆容易老化、皲裂、遇潮漏电、或出现线间打火等情况，使得变压器寿命大大缩短；而在选材上，厂家为节约成本或选用较细的铜线或选用铝线绕制，使得变压器绕组升温更快；当次级的负载电路有短路或大电流出现时，变压器会很快超温或致变压器烧毁，这些问题在以前常常应用玻璃保险丝在初级做过流保护，也有用温度保险丝以及应用双金属温控器做过温保护安装在变压器线包外面的，应用一次性保险丝容易产生经常性更换而带来不便，应用双金属温控器又容易出现在不断电情况下再次接通故障负载而扩大故障范围。要解决好超温、过流的及时保护又不更换保险丝、也不出现保护后再次接通故障电路这个问题，目前只有PPTC才能达到这个目的。

PPTC又名自恢复保险丝，可因应不同的电路、不同的电流电压和温度的要求，选择一个需要的型号，串联到变压器的初级或次级即可，正常工作时是低电阻，当变压器超过规定的温度、或超过规定的电流后会瞬间变为高电阻，及时限制了电路的电流而达到保护变压器的目的。当断电或故障排除后自动恢复为低电阻，变压器恢复为正常状态，PPTC在没有断电的情况下是不会自动恢复的，不会产生在不断电情况下再次接通故障负载而扩大故障范围的问题，同时也解决了超温、过流的及时保护又不更换保险丝的问题。

【应用】基于玻璃放电管、TVS管和电阻设计的通讯电子设备浪涌保护电路设计方案

本文将介绍通讯电子设备的常见浪涌保护电路及硕凯电子器件选择方案，适于埋地电缆引入或其他浪涌电流较小的场合使用，BLSA1、BLSA2用YA-301型或YS-301型玻璃放电管，TVS管用P6KE220CA型，如果传输线上没有振铃信号，TVS管可用P6KE68CA型。

PTC自复保险丝为豆浆机等小家电的电机提供堵转保护

在以豆浆机、搅拌机、打蛋机等为代表的家电中，为避免遭遇“难啃”的大块头引起电机堵转从而烧毁电机等，可使用PTC作为电机的堵转保护，一旦电机发生了堵转，由于堵转的电流是数倍于正常工作电流，PTC只要流过的电流是正常工作电流的2倍即可启动保护，而此刻电机的整体温度往往并没有升起来，避免了高温对电机的冲击。

【经验】自恢复保险丝和TVS的结合使用，可防止四种情况造成的损坏

单独使用自恢复保险丝，或者与TVS二极管结合起来使用，都能防止负载电流过大、转换器出现故障、发动机激活时产生的瞬变电压以及汽车电池极性接反导致器件损坏。在选择PPTC自恢复保险丝器件时，必须考虑到最大负载电流、最高环境温度以及进入高阻抗状态所需要的时间。
