Fixing Magnetically Operated Sealed Switches of Current Protections in Closed Electrical Pathways of Electrical Installations at 6-20 kV

摘要

Three devices are offered for fixing magnetically operated sealed switches at a safe distance from conductor wires. It is demonstrated that they provide current protection without the use of current transformers. It is described how to adjust and calculate the current in the wire where the magnetically operated sealed switch functions.
