MODELING OF MULTI-PULSE TRANSFORMER RECTIFIER UNITS IN POWER DISTRIBUTION SYSTEMS

A device for hand-carrying articles includes a metal carrying handle and an elongated carrying strap. The handle has a pair of spaced apart, elongated side sections which extend along and are positioned on opposite sides of handle axis. The side sections are interconnected at their upper ends by a handgrip portion which extends transversely to the axis, at their lower ends by a lower crossbar which has an elongated slot formed therethrough, and at longitudinally intermediate portions thereof by a central crossbar to which is anchored an end portion of the carrying strap. To carry an article, the strap is looped around the article to define a carrying loop portion of the strap. The free end of the strap is then passed over the lower handle crossbar and then back through the crossbar slot to define in the strap a strap connecting loop portion. When the handle is lifted, the connecting loop portion is frictionally locked to the lower crossbar to prevent enlargement of the strap carrying loop. The carrying loop may be rapidly tightened or loosened by simply pulling an appropriate portion of the strap outwardly from the handle at an angle to its axis. An auxiliary handle is provided for instances in which two handles are needed to carry the article.
