摘要： The fuseholder includes a current limiting fuse mounted within a fuse body and a lower contact and hinge assembly. The fuse body has contact assemblies mounted on each end thereof. The lower contact assembly on the fuse body is mounted on a hinge which is rotatably supported on an interchangeable cutout mounting. The current limiting fuse includes a fuse element spirally wound around a spider which extends the length of the fuse body. The fuse element includes a high current fusible element and a low current fuse element. The fusible element includes a plurality of spaced reduced areas and is supported on the spider by support surfaces which are located between adjacent reduced areas of the fusible element. An auxiliary wire also extends the length of the fuse body about the spider. The hinge includes a hinge member rotatably mounted on the interchangeable cutout mounting, a connective member supporting the contact assemblies and fuse body with current limiting fuse, and a latch for latching the hinge member to the connective member in a contracted position. The latch is connected to a trigger wire attached to the lower end of the auxiliary wire to maintain the hinge and connective members in their contracted position. Upon the melting of the trigger wire due to a current overload, the trigger wire releases the latch thereby allowing the connective member to move to an extended position with respect to the hinge member such that the current limiting fuse drops out of the interchangeable cutout mounting.

摘要： A current-limiting dropout fuseholder includes multiple current paths through the fuse body. A primary current path includes a high current fusible element. A secondary current path in parallel with the primary path includes a triggering conductor that extends outside the fuse body and is connected to a moveable support. The second current path further includes a first spark gap for severing the triggering conductor upon the occurrence of a fault and the shifting of the fault current from the primary current path to the second current path. A second spark gap formed between the primary and the second current paths ensures that the fault current flows across the first spark gap for a time sufficient to sever the triggering conductor, thereby ensuring that dropout will occur.

摘要： A current responsive latching apparatus may be employed in a dropout fuseholder or other electrical component for retaining the component in a current-carrying position and disconnecting and isolating the electrical component upon the occurrence of an overcurrent of a predetermined magnitude. The apparatus includes a current path through the component, including a current-carrying stud or conductor, a portion of which extends outside the component for releasably engaging a support member. A latching apparatus, which may include an actuating member of memory allow or a bimetallic material, engages the conductor to retain the support member in a supporting position beneath the electrical component. The apparatus may further include a heater element in the current path to ensure that the actuation member is heated to the temperature necessary to cause it to change shape and release the conductor upon the presence of an overcurrent.

摘要： A terminal bushing having integral overvoltage and fault current protection includes an insulator having an upper and a lower chamber. Nonlinear resistors are disposed in the upper chamber between a top terminal and an intermediate terminal which are mounted on the insulator. The top terminal, the nonlinear resistors and the intermediate terminal form a first current path through the bushing. The bushing also includes a pair of mounting arms which support a current limiting dropout fuseholder. The fuseholder is disposed in series between the top terminal and a bushing stud which is retained in the lower chamber of the bushing body. A second current path through the bushing is thus formed by the top terminal, the fuseholder and the bushing stud.

摘要： An apparatus for processing an electrical apparatus, such as a capacitor, containing a polymeric dielectric material. The interior of the capacitor casing, which is at room temperature, is initially connected to a vacuum source to evacuate the interior of the casing and when a vacuum sensing unit indicates that the required vacuum has been obtained, a degassed dielectric liquid is supplied to the interior of the casing. A positive pressure is applied to the liquid in the casing to fully impregnate the polymeric layer. When the desired capacitance is obtained, the impregnation is complete and the unit is sealed.
