下面是我找到的定义： / Q; h7 s3 g+ f6 p0 X" \Alive or live (energized). The term means electrically connected to a source of potential difference, or electrically charged so as to have a potential significantly different from that of the earth in the vicinity. The term "live" is sometimes used in place of the term "current-carrying," where the intent is clear, to avoid repetition of the longer term.1 v9 b* K, X5 d' K8 q

Current-carrying part. The term means a conducting part intended to be connected in an electric circuit to a source of voltage. Non-current-carrying parts are those not intended to be so connected. : E' f8 {* R. h& W- k, F 5 M# Y0 a, \8 R; wDead (deenergized). The term means free from any electrical connection to a source of potential difference and from electrical charges: Not having a potential difference from that of earth., h" \( ?5 z7 ]* R3 n3 _8 I
NOTE: The term is used only with reference to current-carrying parts which are sometimes alive (energized).4 Y7 e5 x6 J% Z* H* e) t% J" N e 作者: Jason020 时间: 2012-8-7 08:41
不同点：第一句说的是载流部件及SELV部件，第二句说的是带电部件。作者: Nezof 时间: 2012-8-7 09:24

那截流部件与带电部件有什么明显的区别？作者: Clears 时间: 2012-8-7 11:38
载流部件是电流可以通过的，诸如导线；带电部件是指物体带电，不一定要有电子的定向移动~~作者: gaolujie99 时间: 2012-8-7 13:05
不错，听君一席话胜读十年书！！
