首先第一个问题,热熔体(温度保险丝)是不是非自复位热断路器?; ]5 Q* S5 k/ J1 n
回答:% N- i# g& A7 d2 |# @
非自复位热断路器的定义是:

% O2 \2 V/ P7 `& g- ~9 Z3 Wthermal cut-out that requires a manual operation for resetting, or replacement of a part, in order to restore the current

2 q" q+ k* d. s8 |8 A D- K$ i% Z热熔体(温度保险丝)的定义是:
% V% n: j8 D, u6 h4 @$ v, @# m) O3.7.7 thermal link8 L( S1 k6 x$ H* l
thermal cut-out which operates only once and requires partial or complete replacement0 W+ T$ P2 o: X! P1 _5 R; I3 j* ~
4 j( b+ e* Y- e) I: L比较可知,thermal link只是一种特殊的thermal cut-out(只动作一次且需替换), thermal link也符合non-self-resetting thermal cut-out的定义。再形象点,如果把thermal cut-out比作马,thermal link 属于母马而且还是白马的话,non-self-resetting thermal cut-out就是白马(包括公白马和母白马)。0 X9 _8 _4 Z$ h8 X
