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. C9 M# r, r R

如果分不清楚就按照说明书把产品运行一下,看一下就知道了究竟是什么了,然后再去查元器件的证书看看耐久的次数是不是符合要求5 V6 f8 u' E& `

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. 1 w- ]2 j2 s6 d% `$ r

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9 [: @3 E0 a7 Z
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.

另外, 2楼的解释也有问题,前看下面的条款
* H5 k( c! B2 u7 z24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not9 g# M- R1 h# W$ ~8 s

另外希望管理员给出加威望和金币的原则. |
