【经验】如何为汽车线束过流保护选择一款合适的PPTC保护器件?
汽车线束从功能不同可分为信号线和电力线,其中信号线是传递传感器指令且不运载电力的细电线(光纤通信),而电力线是运载大电流的粗电线,利用分布式架构,从电池取电后,经由汽车高压配电盒、中心接线盒,将全车的各种主要和次要电线总成流向不同的电气负载(如:空调耦合器、风扇、通风电机、车窗电机、后视镜、门锁等),其典型应用框图可参考如下图1所示。
图1:汽车线束分布式架构示意图
通过如上图示,相信大家已经清楚汽车线束的分布式架构,那么,作为承载着汽车线束电力传输枢纽的接线盒,因流经线束的电流一般均很大,为防止因大电流过流出现线束烧毁,需要在接线盒端加入车规级、耐高温、径向引线型自恢复PPTC做过电流防护,可参考如下图2所示。
图2:汽车接线盒选用PPTC做线束过流防护实物图
那么,针对流经汽车线束的电流大小一般为多少安培呢?针对汽车线束允许通过的电流大小是与线束的导线截面积有关,在《燃料电池汽车技术线束规范》中有明确给出其关系,具体可参考如下图3所示。
图3:汽车线束不同导线截面积与允许流经电流大小关系
通过如上图示易知:
·当选择的线束导线截面积为0.35mm2时,在30℃条件下安全载流量为8A,在50℃条件下安全载流量为6.5A;
·当选择的线束导线截面积为2.5mm2时,在30℃条件下安全载流量为32A,在50℃条件下安全载流量为22.7A;
·当选择的线束导线截面积为4.0mm2时,在30℃条件下安全载流量为42A,在50℃条件下安全载流量为29.8A;
那么,如何根据如上的电流参数选择一款合适的电流保护器件呢?
以选择线束导线截面积为0.35mm2为例,在30℃条件下安全载流量为8A,假定以2倍过电流设计(此过电流倍数以实际设计为准),在30℃条件下流经的过电流为16A,故需要一款动作电流ITRIP≤16A、保持电流IHOLD≤8A的车规级、耐高温、径向引线型自恢复PPTC,保证在16A过电流来临时及时动作呈现高阻态状况,此动作时间越短越好。
假定选定的线束工作电压为12V,根据如上设计参数需求,可推荐LITTELFUSE(力特)推出的AHRF 系列16V PolySwitch汽车用高温无铅径向引线型自恢复PPTC,型号为AHRF750,有通过AEC-Q200认证,工作温度-40℃~ +125℃,其实物图和尺寸图参考如下图4所示。
图4:AHRF750自恢复型PPTC实物图和尺寸图
AHRF750自恢复型PPTC保持电流7.5A,动作电流为14.8A(14.8A/8A=1.85倍),最大工作电压16VDC,最大跳闸时间8s(电流从7.5A→37.5A),如果电流从7.5A→14.8A,最大跳闸时间约1.94s,详细电性参数参考如下图5所示。

下面再提供下littelfuse (力特)AHRF系列PPTC的物理特性和环境测试,有通过双85测试,高低温冷热冲击测试等,参考如下图6所示。
图6:AHRF系列PPTC的物理特性和环境测试
最后,总结下AHRF750自恢复型PPTC的器件优势:
1、 符合ROHS标准,有通过车规级AEC-Q200认证标准;
2、 径向引线型封装设计,可支持更小线径的电路应用,并有助于减轻电线束的重量;
3、 产品设计成熟,兼容大批量电子组装件,被很多车厂广泛使用,产品性能有高可靠性;
4、 世强常备库存,供货交期均有保障;

【经验】如何为电话交换机RJ45端口选择一款合适的过流保护器件?
为保证电话交换机的高可靠性与长寿命,必须对交换机的RJ45端口做过流过压防护,一般在进线端口串联一个自恢复型PPTC然后并联一个压敏电阻即可。推荐一款Littelfuse用于电信设备保护的250V PolySwitch无铅轴向引线自恢复PPTC,型号为TRF250-055UT。高达250Vac中断电压和3A中断电流,通过ITU K.20、GR-1089端口类型2&4 1级认证。
