求助高手:在heater 里经常遇到thermal cut out,thermal cut off,thermostat,请问他们有什么区别?具体怎么使用呀?怎么才
知道是熔断式的还是非熔断式的呢???

thermostat:是温度感应装置,安装在样品中是为了控制和保持样品在正常工作中的温度(温控器)thermalcut-out:俗称热保,在样品遭受非正常工作时温度发生聚变时自动切断样品回路,使样品不工作.thermalcut-off:和thermalcut-out的功能一样,只不过thermalcut-off是一次性的无法复位的,而cut-out是可以复位的.这些是我个人的理解,供参考.
“3.9 THERMAL CUTOFF – A device that incorporates a melting alloy or other material that is calibrated
to permanently open the motor circuit upon reaching a certain temperature.”------摘自UL2111-2002
UL2111-2将热保护器分为:
1. Automatically reset;
2. Manually reset, single operation;
3. Thermal cutoff.
而FUSE只是overcurrent protector.

这些美标中提到的一些,这些大多用于电机上的,自动复位,手动复位和无法复位的.手动复位的又称为PTC温保,有控制电流和温度的二种功能,现用的比较多.
