ABSTRACT:
A contact operating mechanism is disclosed which employs a hydraulic motor means for moving contact members between closed and tripped positions, an accumulator for supplying hydraulic fluid under pressure to the motor means, and a separate gas supply means in fluid communication with the accumulator. The accumulator includes a piston or separating means for dividing the interior of the accumulator into two separate pressure chambers. One of the pressure chambers is connected to the hydraulic motor means and the other is connected to the gas supply means. Preferably, the gas supply means is separately disposed from and permanently connected to the accumulator with a sufficient volume of pressurized gas such that in the event that the piston repositions so as to completely fill the accumulator with hydraulic fluid sufficient gas under pressure is available to stroke the accumulator piston and operate the motor means. A pressure indicating means, such as a pressure activated switch or gage, when connected to the gas supply means provides a means of monitoring minimum gas energy even if the accumulator should completely fill with hydraulic fluid.
