Abstract
A compact operating mechanism for switches and circuit interrupters provides improved input drive arrangement and more particularly to a quick-make quick-break operating mechanism for electrical circuit interrupters, i.e. load-interrupter switches and fault interrupters, the drive input arrangement being capable of either power or manual operation without the necessity of any coupling/decoupling or mode selection.
Claims10
A drive input arrangement for an operating mechanism that includes a stored energy mechanism and having an output coupled to an electrical switch to operate the switch between open and closed positions and a charging input to charge the stored energy mechanism, the drive input arrangement comprising:
- power drive means responsive to an energy source for providing a power-driven output;
- a manual drive input;
- a drive input for driving the stored energy mechanism of the operating mechanism;
- and
- drive coupling means coupled to said power-driven output and said manual drive input for separately and independently coupling movement of said power-driven output and said manual drive input to the charging input without any coupling or decoupling being required, said drive-coupling means comprising a ratchet drive member having internal and external ratchet teeth and ratchet drive means for engaging each of said internal and external ratchet teeth and driving said ratchet drive member.
