| 摘要 |
The invention relates to a device which comprises at least one insulating body (2, 3, 4) comprising a first connection element (6) configured for the direct connection to first coupling means (8) of first electrical equipment (9), a second connection element (6') configured for the direct connection to second coupling means (11) of second electrical equipment (10), at least one protective element (5) for protection against fault currents housed inside the mentioned at least one insulating body (2, 3, 4) and conductive terminals (15,15') for the electric connection between conductive ends (13, 14) of the protective element (5) and the coupling means (8, 11, 12). The insulating body (2, 3, 4) internally comprises at least one semi-conductive means (22, 23) connected to the electric potential of the protective element (5). |
