Communication system thermoprotection device for over voltage suppressor mounted in overvoltage suppressor magazines of communication systems |
摘要 |
A thermal protection device for overvoltage suppressor which includes spaced contacts 6 mounted in overvoltage suppressor magazines 11 of communication systems. A bow-type spring 3 and a melt element 2 l are arranged with the overvoltage suppressor which is mounted in a chamber of a case body or housing 13. The melt element is pierced by at least one arm of the bow-type spring when an overvoltage occurs for short-circuiting the two contacts of the overvoltage suppressor. A thermal protection device with simple components prevents creepage currents between the bow-type spring and the contacts of the overvoltage suppressor 6, a chamber for the overvoltage suppressor is adjacent and abutting to a separate chamber formed in the case body for accommodating a bow-type spring. Between the two chambers there is a separating wall comprising a thermoplastic melt element.
