以下就拿60335-1 来说

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).

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& S, W* c$ S. C. M6 m+ U
7 I" G& @( h/ t' u" N& a" Z/ I在这里要指出的是光从外观是看不出这个元器件是thermostat 还是 self-resetting thermal cutout的.

所以6楼中第一章图片是用在冰箱中的温控器,一般情况下是对的
) ?2 ^8 ?; A# l( {. P8 n$ X但是第三张图片绝对不能说是thermal cutout. 也许用在A产品中是thermal cutout但是用在B产品中就是thermostat了. 举个例子,sandwich maker(三明治炉)中很多温控器都是这个样子的.$ E# k" b. j+ e

24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not

60335-1 的A2已经修改了,所以thermal link 不一定要有证书的. I% g; q* A/ C% `' Z0 B8 [, T0 o" G

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.

另外希望管理员给出加威望和金币的原则. |
