个人认为:以上接地方法不符合安规28.2,它虽然没有靠热变形材传递,但依赖了热变形材料,如果真的变形了,以上接地的后果是全部松掉.- X3 ]. x; }6 F2 Q
60335-1:28.2 Electrical connections and connections providing earthing continuity shall be constructed so that contact pressure is not transmitted through insulating material that is liable to shrink or to distort unless there is sufficient resiliency in the metallic parts to compensate for any possible shrinkage or distortion of the insulating material. NOTE Ceramic material is not liable to shrink or to distort. This requirement does not apply to electrical connections in circuits carrying a current not exceeding 0,5 A. Compliance is checked by inspection. |
