& {$ p# V4 j2 x/ |. v上邊兩個是標准原文,請特別注意3.7.2注,它表明“限溫器”不得進行反向工作(即斷開後不得再自動接通),這是關鍵,而“溫控器”一定會反向工作,否則不可能“保持被控部件的溫度在某些限值之間”。( W3 r$ Q6 u5 e# o' f
與上述“限溫器”有點類似的是切斷電路的“熱斷路器”(3.7.3),但限溫器是“during normal operation ”,即在11章中動作。而“熱斷路器”是“during abnormal operation”,即在19章中動作。因此有時同一個元件,測試時如果在11章動作就叫“限溫器”,如果在19章中動作就叫“熱斷路器”。要求也不一樣,視具體情況而定。”' T( N/ h* `; S: }

“限溫器”真的“不可斷開後不得再自動接通”吗?“熱斷路器”尚无此要求!
: C b: [4 G* t, |) d另外,如何理解“It does not make the reverse operation during the normal duty cycle of the appliance. ”(不得進行反向工作)?还请各位仔细考虑。: q6 {. B6 T" W" @. |7 k* W. N3 O

BARRY的解释我觉得更贴近点,但控温不一定只是高温!制冷也有温控滴。 |
