Abstract:
The patent relates to a method of substantially reducing the build-up of solid arcing products between contacts for making and breaking electrical circuits. The method includes the steps of adjusting the contacts to an arbitrary opening distance at which arcing will occur, placing the contacts in the dielectric fluid under greater than atmospheric pressure, opening and closing the contacts at a fixed operating circuit voltage to determine if the solid arcing product build-up forms, and readjusting the contact opening distance to minimize the value of the parameter VN2d where V is the operating circuit voltage, N is the number of sets or pairs of serially connected contacts and d is the distance between the contacts when in the fully open position.
