Control center with interfitting dielectric barriers for bus bars

Claim 2

A control center for distributing electric power from a power supply source to power consuming devices, comprising: a plurality of cabinets having a plurality of vertically spaced compartments in each cabinet; a set of a plurality of vertical, horizontally spaced, bus bars in each cabinet; a set of a plurality of horizontal, vertically-spaced, bus bars in each cabinet and electrically connected to corresponding vertical bus bars; a dielectric barrier on each side of at least one of the sets of horizontal and vertical bus bars and the barrier on each side comprising a number of barrier sections disposed along the length of the bus bars and in surface-to-surface contact therewith; the barrier sections being sheet-like members having opposite side, edge, and end surfaces; first cooperating interfitting means including first tonque and groove members extending from facing side surfaces of each barrier and between the bus bars of each set of bus bars; and second cooperating interfitting means including second tongue and groove members along the abutting end portions of the adjacent barrier sections.

Claim 3

The control center of claim 1 in which the first tongue and groove members are substantially perpendicular to the second tongue and groove members.

Claim 4

The control center of claim 2 in which an adaptor link is disposed between and attached to the end surfaces of adjacent barrier sections and extends transversely to the bus bars on which the barriers are mounted and in which the adaptor link comprises third tongue and groove members fitting the second tongue and groove members on one of the barrier sections, and fourth tongue and groove members facing a direction opposite that of the third tongue and groove members and fitting second tongue and groove members on the adjacent barrier section.

Claim 5

The control center of claim 3 in which the adaptor link comprises an elongated member extending between the end surfaces of adjacent barrier sections and having third cooperating interfitting means including corresponding tongue and groove members engaging with the first tongue and groove members on each of the barrier sections.

Claim 6

A control center for distributing electric power from a power supply source to power consuming devices, comprising: a plurality of cabinets having a plurality of vertically spaced compartments in each cabinet; a set of a plurality of vertical, horizontally spaced, bus bars in each cabinet; a set of a plurality of horizontal, vertically-spaced, bus bars in each cabinet and electrically connected to corresponding vertical bus bars; a dielectric barrier on each side of at least one of the sets of horizontal and vertical bus bars and the barrier on each side comprising a number of barrier sections disposed along the length of the bus bars and in surface-to-surface contact therewith; the barrier sections being planar members having opposite side, edge, and end surfaces; first cooperating interfitting means including first tongue and groove members extending from opposite side surfaces of each of the sections and between the bus bars of each set of bus bars; an adaptor link between and attached to the end surfaces of adjacent barrier sections and comprising second cooperating interfitting means including corresponding tongue and groove members engaging the second tongue and groove members on the barrier sections; and the adaptor link also comprising an elongated member extending between the end surfaces of the adjacent barrier sections and including third cooperating interfitting means having corresponding tongue and groove members engaging with the third tongue and groove members on each of the barrier sections.

Claim 7

A control center for distributing electric power from a power supply source to power consuming devices, comprising: a plurality of cabinets having a plurality of vertically spaced compartments in each cabinet; a set of a plurality of vertical, horizontally spaced, bus bars in each cabinet; a set of a plurality of horizontal, vertically-spaced, bus bars in each cabinet and electrically connected to corresponding vertical bus bars; a dielectric barrier on each side of at least one of the sets of horizontal and vertical bus bars and the barrier on each side comprising a number of barrier sections disposed along the length of the bus bars and in surface-to-surface contact therewith; the barrier sections being planar members having opposite side, edge, and end surfaces; first cooperating interfitting means including first tongue and groove members extending from opposite side surfaces of each of the sections and between the bus bars of each set of bus bars; an adaptor link between and attached to the end surfaces of adjacent barrier sections and comprising second cooperating interfitting means including corresponding tongue and groove members engaging the second tongue and groove members on the barrier sections; and the adaptor link also comprising an elongated member extending between the end surfaces of the adjacent barrier sections and including third cooperating interfitting means having corresponding tongue and groove members engaging with the third tongue and groove members on each of the barrier sections.

Claim 8

The control center of claim 8 comprising fourth cooperating interfitting means including overlapping flanges along the facing edges of the barrier sections.
