以下就拿60335-1 来说

是指在产品正常工作时动作用于控制温度的. 比如98度断开,60度闭合.  (饮水机的温控器)

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

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.

% ^: O3 z; A1 H) D' X- L* o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.9 ?- ]" z, J }9 W

另外, 2楼的解释也有问题,前看下面的条款 Y' A" A- A# L1 B! r
24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not! R2 C6 Q: | n! x

" f, V' G& R' e0 i6 H/ `: r) zClause 19.! x+ I# B" m. {. F R5 E' G" h
60335-1 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.( `# B# K" l6 l0 k; W

另外希望管理员给出加威望和金币的原则. |
