上圖中IEC60601. 對應 DOUBLE那一欄中.
D大于等于0.3MM﹐ 那D是代表什麼﹖ 多謝

Insulation between the primary and secondary in transformers with double insulation:
- 1 insulation layer having a thickness of at least 1 mm
- at least 2 insulation layers with a total thickness of at least 0.3 mm
- three layers provided that each combination of two layers can withstand the dielectric strength test for reinforced insulation
- 1 insulation layer having a thickness of at least 1 mm
- at least 2 insulation layers with a total thickness of at least 0.3 mm
- three layers provided that each combination of two layers can withstand the dielectric strength test for reinforced insulation

三層也有要求,剝掉一層還需要能夠承受3000V的高壓,一般隔離的絕緣片厚度要大於0.4MM
在现在最新版本的IEC60601 标准里(现在都还没使用) 是加有0.4 mm要求, 旧的版本里没有0.4mm 要求, 他的这个培训教材是台湾莱茵的好早的版本.
e) In transformers with REINFORCED INSULATION or DOUBLE INSULATION the insulation
between the primary and secondary winding shall consist-of:
-- one insulation layer having a thickness of at least 1 mm, or
-- at least two insulation layers with a total thickness of not less than 0,3 mm, or
-- three layers provided that each combination of two layers can withstand the dielectric
strength test for REINFORCED INSULATION.
0.4 mm要求在很多其他标准里都有, 但在60601现在使用的版本里没有, 而且任意两层不是承受3000V 耐压, 而是至少4000V, 你是看过其他标准有印象吧
至于级别我根本不在乎, 也不证明什么
