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)

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. ; Y V0 y; o& 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
' R/ M3 _" i5 s( ?! R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8 `2 k' @' R$ e& [( n

另外, 2楼的解释也有问题,前看下面的条款7 q! g5 { X. M7 D3 Z# ?/ m
24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not

60335-1 的A2已经修改了,所以thermal link 不一定要有证书的.8 o. @4 n8 `) _- v O

另外希望管理员给出加威望和金币的原则. |
