1 U: |1 y! s5 D動作溫度可固定或可調的溫度敏感裝置,在正常工作期間,當被控部件的溫度達到預先設定值時, 其以斷開或接通電路的方式來工作。

$ a. R2 c1 Y6 r8 Y; ^1 u4 G6 C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”。3 D, G" A( \2 t4 e+ E6 x
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。”

3 d: E& i7 j) l) X8 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!
$ b3 z& L' P& w# g. l, k( z$ O" K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。* h3 [# u, `# O: l( _

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。 |
