The lower insulating cover wall is nearly thinner as a measure taken to avoid explosion. The inside chamber of this dielectric is filled with SF6 gas with 0.4bar relative force. The dielectric casing is composed of the lower and upper insulating covers. Here, this dielectric casing is outstanding in contamination resistance as well as insulating performance. The SF6 gas insulated load break switch mainly includes two circuits like main circuit & the earthing circuit which are enclosed in a dielectric casing based on epoxy resin. Outstanding arc-extinguishing characteristics.The features of the load break switch include the following. These switches give protection to the transformer and it is an alternative to the two-pole structure. These switches are exposed to different stresses like thermal, dielectric, and mechanical throughout the switching operation. The working principle of the load break switch is to switch the current by moving their contacts mechanically with a suitable speed to make or break the current supply.
So this article discusses an overview of a load break switch – working with applications.
The panel of this switch is available in different configurations like standing Indoor/Outdoor & RMU type. The insulation of this switch will make it lightweight including high mechanical strength & greater electrical safety. The load break switches are mainly made in sheet steel enclosure which provides a simple & solid construction including epoxy insulators, lagging pin, double switch blades, forged contacts with loop less current path & arc quenching chamber.
