IEC60065 章节 2.4.4 名词解释 Conductively Connected to the MAINS
u2 N5 e' u/ G% b7 [+ Gelectrical connection with the MAINS in such a way that a connection through a resistance of 2 000 Ω to either pole of the MAINS causes in that resistance a permanent current greater than 0,7 mA (peak), the apparatus not being connected to earth.& k h' W, X) V: S8 F+ N
* F3 U( m; X1 B" Y9 ~3 z5 _只能理解其字面的含义: 与电网电源导电连接
4 u) g) k; \& @2 p; W0 j/ Z5 p9 Q! r与电网电源的电气连接, 当设备不接地时, 通过2000 欧姆电阻器与电网电源的任一极连接时, 会在电阻器上产生大于0. 7 mA(峰值)的稳定电流.
* n, [6 {( q! B+ Q+ g- A
8 ?8 r- g% T8 ?$ J( l! ^; J9 ?那么怎么理解"与电网电源导电连接的电路"呢? 我试着进行理解: 提取电路中任一个连接, 按照上面的定义, 如果该处与电网任一极的电压差大于1.4V(峰值), 则认为此电路为与电网电源导电连接的电路.' O5 l4 \2 s9 T5 d: f; t
8 \/ z, U+ T( w) J请高手帮忙解释, 以上理解是否正确? |
