23 Fuse US10156838 2002-05-30 US06720858B2 2004-04-13 Uwe Kaltenborn; Lutz Niemeyer
In a fuse chamber (8) there is arranged as a quenching gas source a burn-off element (11), which concentrically surrounds an arc chamber (10) and is separated from it by a fuse element (9), which consists of metal foil, preferably silver foil, and the outer side of which is adjoined by the burn-off element (11). The latter consists of an igniting material (12), arranged in the form of a ring running around centrally, and a gas-evolving material (13). Both materials consist, for example, of guanidine or guanidine derivatives as the combustible material and an oxidant, the proportion of which in the igniting material (12) is hyperstoichiometric. The arc chamber (10) is bounded at opposite ends by nozzles (7a,b), which connect it to exhaust volumes (4a,b). When there is an overcurrent, the fuse element (9) heats up to the igniting temperature of the igniting material (12) and is torn open centrally. The arc forming is axially blown by the quenching gas, which forms during the burning-off of the burn-off element (11), and quenched. The fuse element (9) may centrally have a triggering zone, where it is more easily interruptible, in particular meltable. The quenching gas source may also comprise compressed-gas tanks or cold-gas generators.
24 Current limiting fuse and dropout fuseholder US484653 1995-06-07 US5760673A 1998-06-02 Stephen Paul Hassler; Stephen Paul Johnson; John Lapp
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.
25 Nested contact and cap assembly for fuseholder US65439 1993-05-24 US5355111A 1994-10-11 Stephen P. Haasler; Stephen P. Johnson; John Lapp
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.

36 Terminal bushing having integral overvoltage and overcurrent protection US173786 1993-12-27 US5583729A 1996-12-10 Stephen P. Hassler; Gary L. Goedde; John Lapp
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.

An electrical interruption device is disclosed in which an overcurrent protective device is provided to interrupt electric current flow on a sustained overcurrent current occurring. The overcurrent protective device is characterized by a plunger which is held in tension against the force of a spring by a low temperature solder, and further in which a sleeve of insulating material, such as silicone, is provided about the plunger. Preferably, the overcurrent protective device includes a housing, with the plunger disposed in the housing and having one end extending therefrom to provide electric communication with the remainder of the electric circuit. The sleeve of insulating material preferably being located about the end of the plunger which extends from the housing. On a predetermined condition causing the solder to melt, the plunger is released and under the force of the spring is moved to a position retracted within the sleeve, interrupting the current flow. Advantageously, the overcurrent protective device may be used together with pulverulent arc quenching material. The sleeve acts to isolate the pulverulent arc quenching material from the plunger and prevent its interference with the plunger as it is moved under the force of the spring.
