AS/NZS 3120中Current breaking test要求不甚明白:1 i) n# |: W6 ?& u
...
* }' J; y, s7 Y$ h: J6 P(a) A plug shall be inserted in the socket with no current flowing.% U! H) [4 r/ u r5 u+ @

. i* F* f* \/ I6 t, ?' H以上是说插头插入插座时要求不通电流,插入后立即通电维持15S, 之后插头拔出插座,拔离插座的状态维持105S; 然后继续开始第二个循环吗?那有这样的插拔设备可以做到这个吗?一般我知道是直接机械插拔或者带电插拔,这个要求好像有点复杂,我也不明白标准这么要求是基于什么考虑?6 ?6 W7 \% b0 D1 ~
2 @6 G% J* C* R$ s另外,以下这句话是不是表示,如果产品带接地,要求接地也通电流!Where an earthing contact and an earthing pin are included, the earthing terminal of the socket shall be connected to the neutral terminal during the test.- a/ t3 m+ j& L h* l4 X
