ARC-EXTINGUISHING CONTACT SYSTEM Russian patent published in 2019 - IPC H01H33/00 

FIELD: high-voltage instrumentation engineering.

SUBSTANCE: invention relates to the field of high-voltage instrumentation, and more particularly to the elements of the construction of load-breakers. Arc extinguishing contact system of high-voltage load break switches contains fixed contacts in the form of contact knives, arc extinguishing movable and fixed contacts with contact clamps when closed. Creating the necessary insulating gap between the fixed contact and the contact knives at the moment of breaking arcing contacts when the load is disconnected it is carried out by a stationary arcing contact in the form of a contact plate rotating alternately on two axes, the tensile spring, which creates simultaneously a contact clamp, to the axes.

EFFECT: technical result is simplified design, smaller dimensions.
