【经验】以6.3x32mm管状保险丝实例教你读懂保险丝参数

时间： 2018-04-04 来源：世强

技术问答

保险丝基本概念：

1.正常工作状态时保险丝是起连接电路的作用。

2.非正常情况下(超负载)，保险丝是断路，保护后级电路作用。

3.保险丝分慢熔（Time Lag）、快熔（Fast Acting）、特快熔（Very Fast Acting）等。

4.从分断能力上有低分断和高分断。

5.安全标准：UL/CSA(北美)，IEC(中国，欧洲)，MIT/KTL(韩日)。

保险丝重要参数：

1.电流额定值（Ampere Rating）：又称工作电流，在长期维持正常工作的最大电流。

2.电压额定值（Voltage Rating）：又称工作电压，选型时此电压应大于保护回路的输入电压。因保险丝的阻值非常低，只有当保险丝试图熔断时，保险丝的电压额定值才变得重要。当熔丝元件熔化后，保险丝必须能迅速断开，熄灭电弧，并且阻止开路电压通过断开的熔丝元件再次触发电弧。

3.分断能力（Interrupting Rating）：分断能力就是指在额定电压下，保险丝能够安全断开电路，并且不发生破损时的最大电流值，保险丝的分断能力必须等于或大于电路中的可能发生的最大故障电流。

4.过载能力（% of Ampere Rating）：保险丝在规定时间里维持最大过载电流，通常以100%、135%、200%、250%等过载电流标定。

5.熔断积分 (Melting Integral)：保险丝的熔断积分，是熔断这一保险丝的熔丝元件所需的能量，也称之为熔断值I²t。

下面以LITTELFUSE 尺寸大小为6.3x32 mm的250V/30A 管状保险丝 0314030.MXP和0325030.MXP举例说明，其实物图参数如下图1所示。其中0314030.MXP为快熔保险丝（Fast Acting），而0325030.MXP为慢熔保险丝（Time Lag），先提供下两者的电性参数对照表，参考如下图2、图3所示。

图1：管状保险丝0314030.MXP和0325030.MXP的实物图

图2：littelfuse快熔保险丝0314030.MXP电性参数表

图3：littelfuse慢熔保险丝0325030.MXP电性参数表

通过如上两个图示，我们可以从littelfuse快熔保险丝0314030.MXP和慢熔保险丝0325030.MXP电性参数中得到哪些信息呢？

1、分断能力（Interrupting Rating）不同：

快熔保险丝0314030.MXP分断能力是100A@250Vac；慢熔保险丝0325030.MXP分断能力是400A@250Vac，两者相比，前者属于低分断能力，后者属于高分断能力。

2、熔断积分I²t不同：

快熔保险丝0314030.MXP的 I²t为2490 A2s，慢熔保险丝0325030.MXP的I²t为1690 A2s，说明快熔保险（0314030.MXP）需要更多的能量方可熔断，而慢熔保险丝（0325030.MXP）则需要相对很少的能量使保险丝熔断。

下面再介绍下保险丝过载能力，提供快熔保险丝0314030.MXP和慢熔保险丝0325030.MXP电流过载能力对照表，参考如下图4、图5所示。

图4：littelfuse快熔保险丝0314030.MXP电流过载能力参数表

图5：littelfuse慢熔保险丝0325030.MXP电流过载能力参数表

通过如上两个图示，我们可以从littelfuse快熔保险丝0314030.MXP和慢熔保险丝0325030.MXP电流过载能力参数中得到哪些信息呢？

1、在100%、135%的额定电流下，针对额定电流为30A的保险丝，0314030.MXP和0325030.MXP所需要的熔断时间是等同的，分别为4hours Minimum、1hours Maximum。

2、在200%额定电流下，即200%过载条件下，快熔保险丝0314030.MXP熔断所需要的最大时间仅为30s，而慢熔保险丝0325030.MXP熔断所需要的最大时间需要60s。

最后，介绍下保险丝的适用电路：

• 特快熔(very fast acting) ，快熔(Fast acting)保险丝适用于较恒定电路或浪涌较小，抗冲击脆弱的元件。

• 慢熔保险丝适用于正常浪涌电流电路，没有抗冲击脆弱的元件。

• 分断电流保险丝管适用于可能出现较大短路电流的电路。

• 大电压350V/300V的保险管适用于电子整流器等产品

相信通过上面的介绍，相信可以读懂保险丝的参数含义，如果您感兴趣记得收藏和点赞哦，感谢！有问题请留言或电话联系世强400-887-3266。
