什么标准?
: y) X3 D! J2 E n5 L+ D这里是什么结构?

从上述信息我猜测:

右侧白色的部件为金属件且是易触及的。: g. Y b9 ^* P
左侧的导线只有基本绝缘。$ V! p# [2 O" [% T+ R+ G
( Q" S d" K' B那么就不符合标准要求了。
' h, D% |2 b. |2 H- ^8.2 Class II appliances and class II constructions shall be constructed and enclosed so that there is adequate protection against accidental contact with basic insulation and metal parts separated from live parts by basic insulation only.

1、在导线与金属部件间增加符合附加绝缘要求的隔离垫或在导线外增加护套(固体绝缘);4 W% X3 M# z% R$ L; G$ E o
2、将导线与金属部件在空间上隔离开(电气间隙)。+ c$ Z$ W# z4 F$ A) `
