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

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( o0 g4 v3 p% \; ]: _
% Z! S j3 Z+ U j0 b& f6 B
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. 7 [' p, V2 O3 T9 ]* T2 g
2 z1 T% b; l( v' n$ p
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9 F$ E. E8 H4 ^' \8 A
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.+ j: g8 y5 O$ |7 P! [& @: Z* n

判断是不是温控器是要运行产品来判断的
6 x! g$ D8 e$ |8 w' B- ?: H$ t% A
另外, 2楼的解释也有问题,前看下面的条款
2 v; s- T7 |* n8 X$ Y4 y" `+ Y6 s9 D24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not& {' }* N( {6 h7 C6 b6 m! ]

3 L5 k( M9 l4 h6 Q3 M, HClause 19.
! N1 C! z/ |. K7 e$ e60335-1 的A2已经修改了,所以thermal link 不一定要有证书的.

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.
- l6 O" t: f1 R& y- M; f. _% X1 ~9 r, j: k! h3 J: e K, i& \
另外希望管理员给出加威望和金币的原则. |
