US 5,687,466 A · Maintenance rack for power system reclosers

Abstract

A maintenance rack device for use in the performance of a maintenance, or service task on large electrical utility equipment known as reclosers. The maintenance rack includes a portable tiered frame structure adapted with tiered service members that support reclosers that have a mechanical configuration equivalent to those known in the power distribution industry as type R, W, 6h and V6H reclosers. The tiered service members include opposing support plates that support a first type of reclosers and which facilitate removal of the recloser head covers to gain access to the recloser mechanism. A second service member includes a rotatable service bar member for attachment to a second type of recloser and subsequently to the frame structure for manipulating the recloser mechanism that is to be serviced. The reclaser maintenance rack eliminates having to use tables, barrels to service the recloser devices.
