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).

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.
) |+ n' k- R' n, L! ]: ~9 ?' [- h: e( z
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8 _8 a$ I& e4 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.) a5 e, Y1 m1 e* {

另外, 2楼的解释也有问题,前看下面的条款$ @4 G. @ u& i( C: F$ A4 h
24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not

- A1 j! e+ _# J; B, v60335-1 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.0 T6 S! p3 K5 Q5 x1 I/ m

另外希望管理员给出加威望和金币的原则. |
