Primary surge protector for broadband coaxial system |
摘要 |
A surge protector is adapted for a broadband coaxial system in which electrical signals having a frequency range from DC to one gigahertz are transmitted. The surge protector has a pair of coaxial cable connectors, a surge protection device, and a fail-short mechanism. The fail-short mechanism has a first operating condition in which the center and outer conductors of the coaxial cable connectors are isolated from each other and a second operating condition in which the center and outer conductors of the coaxial cable connectors are conductively coupled to each other. The impedance of the fail-short mechanism allows the surge protector to have an insertion loss with a magnitude not greater than about -0.2 decibels and a return loss having a magnitude of at least about -20 decibels, and the fail-short mechanism is adapted to conduct a fail-short current having a magnitude of at least about 30 amperes for at least about 15 minutes when the fail-short mechanism is in its second operating condition.
