Initially, no more than half the voltage prescribed in IEC 60598-1, Table 10.2 for Class II luminaires is applied between the contacts and the metal foil. It is then gradually raised to the full value. 耐压描述的是端头和金属箔之间,只是可触及绝缘部件需要金属箔,那端头与金属部件(铝板)之间需要通过耐压测试么?我的理解是带电部件与非金属部件(金属箔包裹)之间,带电部件与金属部件(铝板)之间均需通过耐压测试。 |
