水轮发电机的集电环是励磁电流的通道,也是发电机重要部件之一。但往往不引起人们重视,维护不好,集电环易损易腐蚀,轻者引起电刷跳火及建压困难,严重者被迫停机,使机组提前报废。下面谈谈我站对集电环维护的点滴经验。 (1)集电环表面要保持清洁,定期用0号沙布研磨,除去氧化层,研磨后再用绸布或细沙白布抛光,一则使表面光滑,二则把表面杂物除去。研磨、抛光方法,备二块100mm×40mm×10mm木条, The slip ring of hydro-generator is the passage of excitation current and is also one of the important components of the generator. But often do not cause people to pay attention to, maintenance is not good, slip ring vulnerable to corrosion, light flashover caused by light and difficulty in building pressure, severe forced to shut down, the unit scrapped in advance. Here to talk about my station on the collector ring maintenance bit by bit experience. (1) The collector ring surface to be kept clean, regularly polished with No. 0 Sabouraud, remove the oxide layer, polished with silk or fine sand white cloth polishing, one to make the surface smooth, the two remove the surface debris. Grinding, polishing method, prepared two 100mm × 40mm × 10mm wood,
