AS/NZS 3120中Current breaking test要求不甚明白:
C% k! t( l+ x4 b5 Y+ ]# l" u...

5 K6 `2 n9 K" C1 A5 g/ d(b) Immediately following each full insertion, a current as prescribed in Items (i) and

3 E) R) K( A+ P0 L' ^ U2 q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?1 h6 i: h/ @" z/ R" L6 i* ]
* K: L* w3 }& r7 U2 a5 W
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.
