| 摘要 |
The invention relates to a surge arrester comprising an integrated protection device, in particular against sustained, mains frequency overvoltage (TOV), comprising at least one varistor and a PTC resistor, which is in thermal contact with the varistor. The varistor and the PTC resistor are electrically connected in series. According to the invention, a ceramic disc with PTC resistor behaviour is situated between two varistor discs in a sandwich construction, said elements being directly interconnected both mechanically and electrically. |
