【选型】轨道交通控制板电源输入过流防护推荐力特3AB陶瓷管保险丝,额定分断电流能力10kA
为避免轨道交通控制板110V直流电源输入因负载短路异常造成燃烧风险,需要在电源输入母线上加入一颗高分断电流能力保险丝做过流保护设计,此保险丝选型因素参考如下:
1、额定电压考量:110V直流输入,纹波电压一般为±10%,选择耐压为125VDC保险丝即可;
2、额定电流考量:一般与负载相关,一般情况下,额定输入电流在5A左右,依实际设计考量选择设计裕量,可以选择1.2~2倍过流,建议选择额定工作电流为6A~10A的保险丝;
针对如上的设计需求,推荐选择LITTELFUSE(力特)3AB陶瓷管保险丝0314010.MXP,为快熔型保险丝,典型尺寸φ6.3x32L mm,额定工作电压250VAC/125VDC,额定工作电流10A,额定分断电流能力达10kA@125VDC,工作温度范围-55℃~125℃,典型电性参数参考如下图1所示。
图1:Littelfuse(力特)3AB陶瓷管保险丝0314010.MXP典型电性参数示意图
推荐理由如下:
1、 额定分断电流能力高达10kA@125VDC,具有出色的安全切断电流能力,对系统高安全性提供保障;
2、 常温25℃条件下的正常冷却阻值为0.0105Ω,自损耗很小;
3、 工作温度范围-55℃~125℃,适用于极端低温环境工作;
4、具有良好的供货交期,可以快速支持样品和量产服务。
