我搜索到之前的帖子有人把它解释为“ 19.102 限制入风测试,最高档和最低档,风口水平和风口垂直,总共做4部机,限制入风口知道跳制动作,然后微调如风到跳制刚好不跳的状态,最后吹30分钟稳定,” 7 r1 z2 {, p% F. a! g4 f) y! y; m5 c9 k {! j# ?
请问以上解释是对的吗？ 9 l' C% y5 j' P3 D% D. y+ v/ M. X 1 V/ U7 w6 {! y# f但有人认为是“不断反复让THERMOSTAT跳和不跳之间测试30分钟”。8 P+ I1 |1 _( e6 o+ g

行业中所能见到的热断路器和温控器在称谓、外观形状、标称参数等方面并不一定截然分开，也不必截然分开。一个温度控制元件，只有被应用到器具中，明确它特定的控制目的，才具有定义中的具体含义。那楼主认为这个部件是为了正常工作时控制温度还是故障时防止温度过高？叫什么不重要，关键是其控制的目的。作者: juanstery 时间: 2011-6-23 13:35
专家，既然知道结果何必不告诉我一个结论呢？ : N, }/ Y, m Y7 W0 t; P7 k7 L& f1 j ]
因THERMAL-CUT OUT 本人认定此风筒上的FUSE,而不是thermostat,就是偏向于第二种观点，也就是避免PREVENT 保险丝烧，让THERMOSTAT在30分钟不断的做往复工作。。作者: 红豆绿豆 时间: 2011-6-23 17:12 标题: 回 4楼(juanstery) 的帖子 FUSE不可认为THERMAL-CUT OUT作者: 极品老工 时间: 2011-6-23 17:16
那俗称叫热FUSE的算不？不是电流FUSE。作者: shiya888 时间: 2011-6-23 22:59

如果LZ碰到没fuse的电吹风就不会烦恼了！
