<p>A single-pole circuit interrupter is provided that includes a sealed housing containing a pressurized gas, relatively movable contacts and an operating mechanism for operating the relatively movable contacts. The operating mechanism is responsive to a low-speed rotational charging input and includes energy storage means capable of being charged and storing operating energy and charging means responsive to the low-speed rotational charging input for charging said energy storage means. Thus, the only seal to the environment for the overall single-pole circuit interrupter is at the single low-speed charging input. The operating mechanism includes linear stored energy devices arranged so as to generally define one or more planes or arrays and a latch arrangement that is disposed intermediate the stored energy devices and operating in a direction substantially perpendicular to the one or more planes or arrays. In one arrangement, the operating mechanism incorporates an integral multi-revolution recharging drive and force reducer for recharging the operating mechanism after operation.</p> |
