摘要： The present invention relates to a wire-wound fuse resistor, which has: an insulating rod which has a first end and a second end; one metal wire having a wire head and a wire tail, being helically wound around the insulating rod from the first end to the second end, and being cut at a middle portion thereof to form a first winding wire and a second winding wire, which are separated from each other; a connection part disposed at the cut portion for electrical connection between the first winding wire and the second winding wire, in which the melting temperature of the connection part is lower than that of the one wound metal wire, wherein the connection part is cut off depending on a predetermined melting temperature or melting speed of the wire-wound fuse resistor.

摘要： A release apparatus includes a coiled restraining wire with at least one end attached to a fuse wire. Actuation current through the fuse wire causes it to break; breakage of the fuse wire allows the restraining wire to partially uncoil and allow the release apparatus to transition from a retained condition to a released condition, by allowing disengagement a sleeve from retention members and disengagement of retention members from a release member that can then move out of the release apparatus. The sleeve isolates the restraining wire and fuse wire from load forces on the release member. Rolling bearings within the sleeve against the retention members reduces resistance to disengagement of the sleeve. The release apparatus can be employed to attach a deployable component to a satellite or spacecraft, and can be readily repaired, refurbished or reset for repetitive ground testing.

摘要： A fuse cutout insulator for use in power distribution systems includes three electrically conductive pieces spaced apart and encapsulated by a dielectric material. The conductive components include a top hood, bottom pin, and central pin. The central pin is generally tube shaped and includes an outwardly extending flange to facilitate attachment of the fuse cutout to a utility pole. The top hood and bottom hinge include the traditional components for operable holding of a fuse tube member. The top hood and bottom hinge are accepted in opposite ends of the central pins bore and sealed in spaced relationship during manufacturing by the dielectric material added for fabricating the weathersheds.

摘要： A circuit protection assembly (CPA) is disposed between a source of power and a circuit to be protected. The CPA comprises a mounting block having a bore extending therethrough and a recess cavity on a first surface of the mounting block. A post having a first end is disposed within the recess cavity and a body portion extends through the bore. The body portion configured to receive a terminal and the second end configured to receive a securing mechanism. A fuse having a centrally disposed aperture is configured to receive the body portion of the post and to receive the terminal for connection to a circuit to be protected. An insulator disposed on the terminal and disposed beneath the securing mechanism. The insulator configured to isolate the post from the terminal and the fuse while allowing the securing mechanism to apply an amount of torque.

摘要： A fuse includes a fuse element and a fuse body. A portion of the fuse element is housed in a fuse body. The fuse element includes a first terminal and a second terminal disposed outside of the fuse body. The first terminal and the second terminal electrically connects the fuse element to a circuit to be protected and a power source. A first endbell and a second endbell is coupled to the fuse element. A predetermined amount of arc quenching material is disposed within the fuse body. The arc quenching material contacts at least a portion of the fuse element. The predetermined amount of the arc quenching material is less than a total volume size of the fuse tube. The arc quenching material is compacted. A remaining air gap in the fuse tube is filled with a liquid adhesive and cured to a solid state.
