Electrical resistance for use in protective switching device, especially power circuit breaker, consists of band of electrically conductive material wound with insulating layer between windings

摘要

The electrical resistance (16) consists of a band (17) of electrically conductive material wound with an insulating layer between the windings. The band consists of a poorly electrically conducting metal. The band can consist of a material with a thermal capacity greater than 3.8 KJ/dm3>K, preferably greater than 4.0 KJ/dm3>K, preferably steel.
