固定带电部件了，
750 °C, for connections which carry a current exceeding 0,5 A during normal operation,
650 °C, for other connections.

碳刷是作为带电体考核的，碳刷的塑料支架，是支撑带电部件了，所以和你是否用什么焊接方法无关了
而且，碳刷的塑料支架，是不是还要做耐漏电起痕试验？

回楼上,标准中30.2.2中不是有一条
The glow-wire test of IEC 60695-2-11 is not applicable to:
– parts supporting welded connections and parts within a distance of 3 mm of these
connections;
所以,如果碳刷是welded这种焊接方式,那么不就可以豁免了??可以这样理解吗?
