各位大侠,关于这个问题,我又特地看了标准,其对于泄露电流这么写的:测量在电源的任一极与连接金属箔的易触及金属部件之间进行,并与绝缘材料的易触及表面相接触我还翻看了英文原版标准:13.2 The leakage current is measured by means of the circuit described in figure 4 of IEC 60990 between any pole of the supply and accessible metal parts connected to metal foil having an area not exceeding 20 cm × 10 cm which is in contact with accessible surfaces of insulating materials.
