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
在現(xiàn)在最新版本的IEC60601 標準里(現(xiàn)在都還沒使用) 是加有0.4 mm要求, 舊的版本里沒有0.4mm 要求, 他的這個培訓教材是臺灣萊茵的好早的版本.
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要求在很多其他標準里都有, 但在60601現(xiàn)在使用的版本里沒有, 而且任意兩層不是承受3000V 耐壓, 而是至少4000V, 你是看過其他標準有印象吧
至于級別我根本不在乎, 也不證明什么
