Heat-sensitive protection device for a surge arrester incorporated in surge protector assemblies for telephone lines

摘要

the invention relates to a thermoschutzvorrichtung for u00fcberspannungsableitermagazine 11 of the fernmeldeu00adtechnik built-in overvoltage arresters 6 which is in a chamber 14 of the gehu00e4useku00f6rpers 13 the overvoltage arresters 6 bu00fcgelfeder 3 and a schmelzelement 2 train eordnet are in the u00fcberspannungsfall to hotwire the two contacts 7.8 of the u00fcberu00adspannungsableiters 6 of at least one federarm 4.5 of the bu00fcgelfeder 3 penetrated.;the thermoschutzvorrichtung with as simple components and kriechstru00f6me train between the bu00fcgelfeder 3 and contacts of 7.8 of u00fcberspannungsu00adableiters 6 to avoid provides that the chamber 14 to the overvoltage arresters 6 in gehu00e4useu00adku00f6rper 13 ausgebilde te separate chamber 9 to absorb the bu00fcgelfeder 3 is attached, and that between the two chambers 9,14 a weir 1 from thermoplastic plastic as schmelzelement 2 is arranged.
