也是指在产品正常工作时动作用于控制温度的, 但是如果温度在98度断开后,是不会闭合的,比如电热水壶,谁烧开之后是不会反复烧的* g3 H7 ]& |% N' m( ?0 Z1 v, C

这个主要是指在非正常动作的, 又可以分为自复位(self-resetting 和和非自复位的(non-self-resetting)./ @1 u1 i0 F+ M- k! C* M1 C

如果分不清楚就按照说明书把产品运行一下,看一下就知道了究竟是什么了,然后再去查元器件的证书看看耐久的次数是不是符合要求

另外, 2楼的解释也有问题,前看下面的条款
8 } g6 }- D; V% ]" ~. Q, ]/ e24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not; m( l! G* |8 o

60335-1 的A2已经修改了,所以thermal link 不一定要有证书的.0 l+ Z1 v/ O8 P' w

另外,我不知道什么人可以给别人加威望,如果只是版主可以的话,请确认是正确的说法后才加威望,否者很容易误导别人的.我不觉得贴了三个图片就可以加5个威望.且不说其中的说法有歧义.: f$ {8 c2 l& W$ w" W" d

另外希望管理员给出加威望和金币的原则. |
