Estimating the term…
A multi-pole group-operated switch is provided for electrical power distribution circuits. The switch is self-contained and suited for ease of use with various line spacings and arrangements of the distribution lines; e.g., side-by-side (horizontal plane), phase-over-phase, and cable drops. The switch includes a plurality of switch-pole units carried at desired spacings by a base support and drive arrangement. Each of the switch-pole units includes a housing, interrupting contacts, and disconnect contacts. The housing that encloses the interrupting contacts in movable to perform the disconnect function. The base support and drive arrangement encloses a high-speed interrupting linkage for operation of the interrupting contacts of each of the switch-pole units and carries an operating mechanism that is connected to the interrupting linkage internal to a base support member of the base support and drive arrangement. The switch also includes a disconnect linkage to move the switch-pole housings. For manual operation of the disconnect function, an operating handle is provided. The operating handle and the operating mechanism are oriented and positioned relative to the switch in various predetermined locations that are desirable for the particular mounting configuration of the switch with respect to the line layout and the equipment pole. In a preferred embodiment, the switch includes integral dead-ending connection provisions and also includes integral line- parameter sensing and power-supply provisions incorporated within one or more of the switch-pole units.
A switch providing an interrupting function and a selective disconnect function between first and second circuit terminals comprising:
A switch configuration comprising:
A distribution switch comprising:
In a distribution switch having a drive linkage disposed within a tubular support member for operating a plurality of switch-pole units, operating mechanism means supported by said tubular support member so as to be external to said tubular support member for imparting movement to said drive linkage, said operator mechanism means including a housing and drive output means extending from said housing and affixed to said drive linkage, said tubular support member comprising means for defining a predetermined opening said drive output means extending into said tubular support member via said predetermined opening, said housing covering said predetermined opening.
A method of providing one of a plurality of different switch configurations by selectively arranging and assembling a plurality of components including base drive and support means, a plurality of switch-pole units disposed at predetermined locations along said base drive and support means, an operating mechanism carried by said base drive and support means at a predetermined location and having a drive output, a disconnect linkage connected to said plurality of switch-pole units, and a manual operating handle movably supported at a predetermined location of said base drive and support means and connected to said disconnect linkage, said base drive and support means including an internally disposed high-speed drive train connected to said plurality of switch-pole units, the method comprising the steps of:
