以下就拿60335-1 来说

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# i7 y- @/ C& w8 F+ g2 U2 a& @

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. - A# |/ I' c' n/ j0 O; }$ O

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
4 k6 C s% M, N' D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.; ~( k* a1 @' @+ P" ]( b

判断是不是温控器是要运行产品来判断的

另外, 2楼的解释也有问题,前看下面的条款
1 [) L1 }" U/ z% O1 \1 S0 B" U. y8 y24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not

Clause 19.+ R/ q; x/ H2 F# i' a
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. ?7 X* O, m7 W# n! r l# y* z8 r0 y

另外希望管理员给出加威望和金币的原则. |
