Abstract: Apparatus for remote closing of fuse circuits for overhead power lines is described which has a body fabricated of insulating material for detachable engagement with a fuse tube, the apparatus having a handle with a head thereon extending therefrom with a cord attached thereto and extending to the ground.The handle is positioned in the apparatus and the cord pulled for swinging the fuse tube so that the fuse tube is moved to a position for closing a circuit, thereby rendering it unnecessary to close a transformer or tip switch from the pole or from a bucket truck. The apparatus normally slides off the fuse tube in closed position but can be removed from the fuse tube by pulling the cord from the ground.

Abstract: An electrical cutout having a support insulator with a line terminal and fuse support assembly at each end, each of which includes a line terminal, a fuse support element and means for their support on the insulator and also includes a contact element more highly conductive than the other elements of the assembly that extends from line terminal to the fuse support element for a continuous highly conductive path therebetween free of mechanical joints.

Abstract: Apparatus for remote closing of fuse circuits for overhead power lines is described which apparatus comprises a rod of insulating material for insertion into the bottom of a fuse tube, the rod having a cord attached thereto and extending to the ground for swinging the fuse tube so that the fuse tube can be moved to a position for closing a disconnect, thereby rendering it unnecessary to close a transformer or tip switch from the pole or from a bucket truck. The rod has an enlarged cushioned head and can be removed by releasing the tension on the pulling cord, and the rod will slide out of the fuse tube and fall to the ground.

Abstract: An electric cutout includes a fuseholder in which a fusible element is mounted, a conducting element pivotally mounted to the lower end of the fuseholder and having a pair of trunnions disposed within a pair of spaced jaws on which a pair of guide surfaces are respectively mounted for cooperation with complementary guiding surfaces of arcuate configuration on the conducting element so that rotation of the fuseholder and conducting element about the trunnions may be effected in such manner that the trunnions are securely held against the bight portions of the jaws thereby to prevent rocking action of the fuseholder during closing movement thereof, an ejector latching element pivotally mounted on the conducting element and arranged to eject the fusible element upon rupture thereof and also arranged to engage a part of the fuseholder so as to prevent relative movement between the conducting element and the fuseholder, a U-shaped contact fixed in position adjacent the jaws and arranged to engage opposite surfaces

Abstract: A fuse recloser for placing a fuse in a vertically oriented fuse holder includes a channel-shaped fuse shoe pivotally mounted within a channel-shaped support. The side arms of the shoe and support flex and the shoe releasably grips a fuse. The exterior of the fuse shoe includes cam surfaces which engage with the outer ends of the support which serve to collapse the shoe onto the fuse while permitting a forced release of the fuse shoe from the support. A release lever is provided for initial separation of the fuse shoe and support, after which the shoe is readily removed from the fuse. A U-shaped handle extends from the support outwardly and then rearwardly in offset relation to the support. A flexible line is secured to the outer end of the offset handle member with a fuse in the shoe and the shoe within the support. The one end of the fuse is placed in lower pivotal mount on the fuse holder and depends downwardly therefrom with the offset handle member extending upwardly.

Abstract: A single-vented fuse tube has a bore lined with an arc-extinguishing material. A movable contact moves away from a stationary contact in the bore and toward and out of an exhaust opening. An arc established between the contacts causes de-ionizing arc-extinguishing gases to evolve from the bore. The gas is exhausted from the exhaust opening. The bore is mildly tapered--to about 1.degree. to 3.degree. of included angle--so that its greatest diameter is at the exhaust opening. The included angle and extent of the taper are sufficient to obviate stagnation of the gases evolved deep within the bore and clogging of the bore.

Abstract: A combination dropout assembly adapted for use with protective cutouts in an electrical distribution system comprises a current limiting fuse electrically connected in series with an explusion-type fuse, and mechanically coupled in skewed relation to the latter, whereby the assembly provides reliable full range fault current protection yet is sufficiently compact in length to matingly span the gate between conductive terminals of conventional 15 KV class opengate cutouts found in many existing electrical distributioon systems. Overload and low to medium fault current protection is provided by the expulsion fuse, while high range fault currents are cleared by operation of the current limiting fuse.

Abstract: An indicating composite sectionalized fuse is provided having a high-current interrupting section, and a mechanically-connected detachable low-current interrupting section in series therewith, with the low-current interrupting section including a pull-away indicating fuse-link cable, which indicates externally a blown condition of the fuse. The low-current interrupting section is replaceable, following a low-current interruption, which has no effect upon the high-current interrupting section, the latter remaining intact and may be further used. During high-current interruption, both sections are fused, and collectively contribute together to a quick interruption of the connected electrical circuit, again there being an external indicated condition of the blown condition of the fuse by an ejection of the fuse-link cable.

Abstract: Load-break switches and current-limiting fuses are often serially connected and placed one above the other. This arrangement is relatively bulky, and involves in particular relatively large requirements in respect to height.The present invention concerns an arrangement of parts wherein the load-break disconnect and the current-limiting fuse are electrically connected in series, but wherein they are arranged spatially in parallel, substantially in coaxial relation, the load-break switch or some of its constituent parts being arranged inside of the current-limiting fuse; or the load-break switch and the current-limiting fuse may be provided with contact means common to both of them.
