Abstract:
A guidance system for an interrupter switcher (10) comprising a first guide (22) positioned in between the contact support (20) and the movable contact system (11) of the interrupter (10), and a second guide (32) inserted into the stationary contact system (15) of the interrupter. The second guide (32) is capable of receiving the nozzle (28) of the movable contact system (11). An interrupter (10) with the guidance system (24) is assembled by positioning the second guide (32) within the stationary contact system (15), inserting the nozzle (28) of the movable contact system (11) into the second guide (32), and mounting the stationary contact system (15) in the interrupter housing (10). The assembly of an interrupter (10) with a guidance system (24) results in a self-adjusting switcher interrupter capable of maintaining a stable alignment between the interrupter's movable (11) and stationary (15) contacts while opening and closing the interrupter (10).
Abstract:
An operating mechanism for a combined interrupter and disconnect switch (10, 11) comprises an operating linkage (17) and an interrupter support housing (41) rotated separately about a common pivotal axis. The interrupter switch (10) is part of a disconnect switch arm and is secured to the support housing. The interrupter contacts are operated by a linearly movable rod (40) which has an end connected to a lever (56) extending from the operating crank (55) and is movable thereby. A linearly movable operating shaft (21) is connected to and moves a crank arm (57). A spring biased latch lever (80) is pivotally mounted to the interrupter support housing and releasably engages the free end of the crank arm lever (56) so that the housing rotates with the crank and closes the disconnect switch (11). When the disconnect switch closes, the latch lever (80) releases and the crank (57) rotates relative to the housing to operate the linearly movable rod (40) which operates the interrupter switch (10).
