Patent ID: 8416541

Claim:
An electrical arc eliminator apparatus suitable for retrofit use with a high current and high voltage disconnect switch assembly, said electrical arc eliminator switch apparatus comprising: a primary jaw support; a secondary jaw support for securing an electrically conductive rotatable blade of a disconnect switch forming a jaw cable circuit and which is able to convey electrical energy from the rotatable blade on-demand without regard to whether the rotatable blade is then currently secured to said primary jaw support; an insulated gated bipolar transistor able to collect and emit high current and high voltage electrical energy on-demand and being comprised of: a gate terminal operative only when a threshold electrical voltage is passing through it, said gate terminal providing a discrete remote point of electrical contact suitable for attachment with said rotatable blade of said disconnect switch assembly for the conveyance of electrical energy; a collector terminal in electrical communication with said secondary jaw support and which is able to receive and collect high current and high voltage electrical energy on-demand from said secondary jaw support; an emitter terminal able to emit and convey high current and high voltage electrical energy only when said gate terminal is operative and which can be placed into electrical communication with the jaw cable circuitry of a disconnect switch assembly; means for positioning said discrete remote point of electrical contact of said gate terminal upon a rotatable blade of said disconnect switch assembly for the conveyance of electrical energy; means for positioning said secondary jaw support to secure an electrically conductive rotatable blade of said disconnect switch assembly; means for placing said emitter terminal into electrical communication with the jaw cable circuitry of a disconnect switch assembly; and wherein said means for positioning said discrete remote point of electrical contact of said gate terminal contacts said rotatable blade simultaneously to turn on said insulated gate bipolar transistor prior to said rotatable blade passing from said primary jaw of said disconnect switch attachment to said rotatable blade.
