7 i9 P/ [! ^% X: R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”。
$ h# o ]; H6 |* N$ i; D0 m+ I- u. W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。” U4 E, q, ?0 L0 d" H

“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!
2 j! B, c& S2 @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。/ Y1 t3 u6 `. B

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。 |
