摘要： A full-range, current limiting fuse which includes a modular fuse subassembly which can be assembled with any pair of several types of paired end caps to construct any one of several types of fuses. This modular subassembly includes a main fuse element helically wound about a gas evolving spider and connected to element termination plates mechanically attached to each end of the spider, and an auxiliary fuse element, electrically isolated from the main element, which is also helically wound about the spider and connected at one end to a contact button centrally disposed at one end of the spider.This modular subassembly is positioned within a sand-filled fuse tube sealed at both ends by brass end caps which are magnetically formed and epoxied thereon. The main fuse element is electrically connected at each end to a respective end cap by terminal tabs of the element terminations which extend through matching openings in the caps, and are soldered therein to hermetically seal the openings. One of these end caps includes a centrally disposed contact button which is electrically connected to an outside surface of the end cap by a high resistance vent wire extending through a passage in the end cap, and which makes electrical contact with the contact button of the modular subassembly to thus connect the auxiliary element to the outside surface of one of the end caps.The fuse can be made watertight by positioning elastomeric gaskets between the caps and the tube which are compressed during the forming operation to form watertight seals, and by filling the vent wire passage in the end cap with elastomeric material. During a fuse operation, the vent wire is vaporized to produce a vent hole for gases generated within the fuse and to give indication of the fuse operation.

摘要： A bayonet-type circuit breaker or under oil fuse device for completing the circuit from a high voltage bushing to an under oil transformer, the bayonet type device including a bayonet assembly having a circuit element at the end and a support assembly mounted on the transformer tank and having a tubular portion extending into the oil in the tank, the tubular portion including a pair of skirts at each contact location on the tubular portion and an elongate band of conductive spring metal material bent into a square configuration and having a number of spring fingers integrally formed along the axis of the band with a contact button on the free end of each finger, the band being mounted on the tubular portion of the support assembly between the skirts in a position to engage the circuit element, the inherent bias of the fingers holding the buttons in engagement with the contacts at each end of the circuit element.
