关于家电IEC 60335-1

作为保护阻抗作用的电容Y1/Y2应如何选择？

335标准，要两个，Y1、Y2都可以，558标准应该是可以只用1个，如果只用一个就只能用Y1

1996/04 - Subclause 22.42 Athens, November 1996, CLC/TC 61(SEC)1098
CLC/TC 61(AT)260
Concerning Y2 capacitors used as protective impedance, the following applies for bridging insulations:
a) Two Y2 capacitors (voltage proof 1 500 V,peak impulse 5 kV); combination Y2 (basic insulation) + Y2 (supplementary insulation)
Not accepted.
Acceptance for two Y2 capacitors with voltage proof 2 500 V only
b) Combination Y1 (basic insulation) + Y2(supplementary insulation)
Accepted for Y2 capacitors with voltage proof 2 500 V only
c) Combination Y2 (basic insulation) + Y1 (supplementary insulation)
Accepted (idem b)
d) Combination of three Y2 capacitors in series Not accepted

2个1500V的Y2电容不能接受？

这个是新的CTL决议吗？在官网上没有查到呢！只看到了DSH-494.
