Patent number: 5023583Abstract: A circuit breaker contact operating structure characterized by a circuit breaker operating mechanism having separable contacts of which one is mounted on a contact carrying arm. The arm being mounted on a one leg of a U-shaped flexible conductor. A guide link is pivotally mounted and connected to the arm to maintain the contacts in alignment during their separation. The operating mechanism having a latch for latching the arm in the closed-contact position of the arm and having a trip device for unlatching the latch in response to an overcurrent condition. The mechanism link is so placed on the contact arm structure as to effect a blow-on force on the contact structure during the duration of high overcurrent. At a preset current level, the mechanism link is prevented from applying the balancing force to the contact structure, thus allowing the blow-off forces due to the current in the contact structure to separate the contacts rapidly, and to effect current limitation and subsequent circuit interruption.Type: GrantFiled: October 21, 1988Date of Patent: June 11, 1991Assignee: Westinghouse Electric Corp.Inventors: Walter V.

Patent number: 4658504Abstract: An electrical boot for the bus bar joints of electrical metal-clad switchgear is taught. The boot is formed by taking a piece of heat shrinkable material, disposing it over a joint or similar construction, heating and shrinking the material so that it shrinks to the shape of the joint or construction in question while at the same time, providing on two opened edges thereof a clamped chill bar which does not allow those portions to cohere to each other so that the boot may be removed after the formation process and easily disposed upon a bus bar joint located within the tight confines of a metal-clad switchgear cabinet. The process may be utilized to form metal-clad switchgear having bus bars with a heat-shrunk insulating boot on the joints thereof. Furthermore during the production process, a bolt envelope simulating template or jig may be utilized to fill out the area on the finalized boot which roughly corresponds to the outer dimensions of the bolt and nut arrangement.Type: GrantFiled: August 23, 1985Date of Patent: April 21, 1987Assignee: Westinghouse Electric Corp.Inventors: Semahat D.

Patent number: 4650085Abstract: An enclosure structure for housing switchgear apparatus (such as circuit breakers) is fabricated from a pair of sheet metal panels that are held in precisely-spaced upstanding relationship by a plurality of metal cross-struts of U-shaped cross-section which mechanically interlock with apertured portions of the panels and are held in such position by triangular-shaped metal gussets which overlap and are bolted to adjacent portions of the cross-struts and panels. The cross-struts are provided with longitudinally protruding tangs at each end that are slip-fitted into and interlock with slot apertures in the panels. The width dimension of the finished enclosure structure is precisely controlled by positioning tabs on the ends of the cross-struts that are offset from the associated tangs and are drawn into abutting relationship with the inner surfaces of the respective panels when the structure is bolted together.Type: GrantFiled: January 27, 1986Date of Patent: March 17, 1987Assignee: Westinghouse Electric Corp.Inventors: Norman Davies, John D.
