Latest Patents

Bruning's latest patents include a "Circuit protecting apparatus including resettable vacuum fuse and switch." This invention features a current-responsive, resettable, violence-free low fault range vacuum-type switch interrupter designed for series connection with a high fault range current limiting fuse (CLF). The device aims to provide an improved, full range circuit protection solution, particularly for pad-mounted, oil-filled switch gear apparatus. The switch incorporates a spring-loaded, over-center toggle motive assembly and a current-responsive, temperature-sensitive, bimetallic U-shaped latching element. In the event of a fault, the element deforms, allowing the motive assembly to quickly open the vacuum contacts without the violence or oil contamination typically associated with fuse links. Additionally, the switch includes a weighted, shock-absorbing element to slow the contacts before engagement during the closing sequence, along with a high-impact hammer arrangement to break any contact welds during fault-induced operations.

Another significant patent is the "Encapsulated vacuum switch having improved switch arm seal." This invention features a high dielectric strength seal between the encapsulant and the actuating arm of an externally operable encapsulated vacuum switch. It includes a fluid-receiving sealed cavity surrounding the actuating arm, which can be charged with a dielectric fluid to reduce the likelihood of corona formation and dielectric breakdown. The design also allows for thermal expansion and contraction of the dielectric fluid without leakage or cavitation.
