通讯接口保护PTC热敏电阻 华巨电子替代EPCOS(爱普科斯)PTC热敏电阻对照表

选型指南      返回上一页面

南京华巨电子隆重推出针对智能电表市场专用的WMZ13E系列PTC热敏电阻,工频电压最高耐压达到600Vac,广泛应用于各种仪器,仪表电子产品的初级线圈过流保护热敏电阻。可以替代EPCOS(爱普科斯)插件系列PTC热敏电阻,对比EPCOS热敏电阻,性价比高,交货快。
1.应用范围: WMZ13E系列PTC热敏电阻器是一种对异常温度及异常电流自动保护、自动恢复的保护元件,它取代传统的保险丝,可广泛用于马达、变压器、电子线路等的过流过载保护。热敏电阻器通过其阻值突变限制整个线路中的消耗来减少残余电流值,在传统的保险丝线路中,其熔断后无法自行恢复,而PTC热敏电阻器在故障撤除后可恢复其保护功能
  选用PTC热敏电阻器作为过载保护元件,首先确认线路最大正常工作电流(就是PTC热敏电阻器的不动作电流)和PTC热敏电阻器安装位置(正常工作时)最高环境温度、其次是保护电流(就是PTC热敏电阻器的动作电流)、最大工作电压、额定零功率电阻,同时也应考虑元件的外形尺寸等因素。 如下图所示:使用环境温度,不动作电流及动作电流三者之间的关系。

2.应用范围: 主要用于智能电表、变压器,电机,开关电源,充电器,适配器,仪器仪表,控制面板,家用电器,空调,微波炉等的过流、过载、短路保护。

3.应用原理:


   将过流保护型型PTC热敏电阻串联在电源回路中,当电路处于正常状态时,流过PTC的电流小于额定电流,PTC处于常态,阻值很小,不会影响电子镇流器(节能灯、变压器、万用表)等被保护电路的正常工作。当电路电流大大超过额定电流时,PTC陡然发热,阻值骤增至高阻态,从而限制或阻断电流,保护电路不受损坏。电流电流回复正常后,PTC亦自动回复至低阻态,电路恢复正常工作。


  过流保护型型PTC热敏电阻在电子镇流器(节能灯、变压器、万用表)等过流保护应用领域。
