你的线盘绕组有没有与托盘接触?如果有接触需做750度灼热丝.见如下标准.
30.2.2 For appliances that are operated while attended, parts of non-metallic material supporting current-carrying connections, and parts of non-metallic material within a distance of 3 mm of such connections, are subjected to the glow-wire test of IEC 60695-2-11. However, the glow-wire test is not carried out on parts of material classified as having a glow-wire flammability index according to IEC 60695-2-12 of at least
– 750 °C, for connections which carry a current exceeding 0,5 A during normal operation,
– 650 °C, for other connections. If the glow-wire flammability index is not available for a sample with a thickness within作者: qing1234 时间: 2011-12-31 16:20
一般的线圈都是与托盘接触的，我们也是做750作者: feazhp 时间: 2011-12-31 16:20
主要现在我同事认为线圈是一整根绕在托盘上的，并没有与托盘进行电气接触，所以就认为不需要做测试，是否正确呢？作者: ejfgde 时间: 2011-12-31 16:20
这个需要做测试的，你的线圈和托盘是有接触的。作者: gzsl2009 时间: 2011-12-31 16:21
托盘只要与线圈接触，或者与线圈的距离小于3mm，就必须进行750度灼热丝测试
