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)

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).6 b! \# o3 }: l& s- s7 ~

9 V* f5 g& p A+ X7 U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.

判断是不是温控器是要运行产品来判断的

5 a4 ]) d' ^6 v4 r另外, 2楼的解释也有问题,前看下面的条款# C( i" A1 H: C6 ~3 b$ h7 y9 G! j
24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not7 l' \* M' d/ z

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.

另外希望管理员给出加威望和金币的原则. |
