十万火急!求翻译VN内容
Earth Grounded-Now the conductor coming from the pay-off reel is bare and it is not earth-groundedat the pay-offreel nor at any other point at which continuous contact with the bare conductor, prior to the insulating process.
Requirements: see spark test requirment
请问此句话的大意是什么?
我看是和火花机测试有关,求证是否是说火花机故障了 踞我的理解是earth-grounded 的连接 出了问题.由于对你们产品不熟悉,所以可能理解有误.
其实你可以电话跟UL检验员沟通是怎么回事. 地线接地—
现在从放线轴出来的导体是裸露的,绝缘工序前面,放线轴既没有接地也没有在任一点连续的接触裸导体。
要求:见花火测试要求。 解铃还需系铃人,谁开的VN 找谁,500美金没有了! 不是花火机本身问题,是接地问题 引用第2楼stevenyu于2009-11-23 15:27发表的:

是这个意思 对于火花测试,UL 2556中有要求,会涉及到接地问题(包括收放线,火花机)
6.7.3 Preparation of specimens
6.7.3.1 If the conductor coming from the pay-off reel is bare, the conductor shall be earth-grounded prior
to the insulating process.
6.7.3.2 If the conductor coming from the pay-off reel is insulated, an earth-ground connection shall be
made at either the pay-off or take-up reel. For 5.26 mm2 (10 AWG) and smaller-sized single-conductor
cables, an earth-ground connection shall be made at both the pay-off and the take-up reels unless the
conductors have been tested for continuity and found to be of one integral length.
6.7.3.3 For other cable constructions, the outermost conductive components shall be earth-grounded.
6.7.3.4 Each earth-ground connection shall be bonded directly to the earth ground of the spark tester. 说得很对啊,押出机我绞铜机都必须接地措施。这是在有规定的。 ,学习拉 我就不搬标准了,这个VN我开过,意思就是产品上的裸露的导体要接地,否则就要提供绝缘。 没啥别的意思了
