Introductions of Core Components Technology
Master Switch Design
a.The master switch adopts vacuum interrupter
b.Particular curve design for reducing force mechanism
①Reduce dosing impact
②Reduce extra work
③No extra contact pressure added when trigger returns
④Diffuse the contact pressure and reduce tripping force when opening
Disconnector Design
a. Disconnectors with three-position design prevent incorrect operations thoroughly in theory design
b. Contact design benefits earthing making, and the making speed >4.2m/s
c. High-performance Mubea belleville spring guarantees stability of the contact pressure
