摘要： The subsea fuse assembly comprises an enclosure (11) filled with a dielectric fluid (80) and provided with an equalization opening (22, 32), which is sealed with a flexible element (40). A first electric conductor (61) extends into the enclosure through a first lead-through (70) positioned in a wall (15) of the enclosure. A second electric conductor (62) is attached to an inner surface of a wall (14) of the enclosure. A fuse (50) is connected between the first electric conductor and the second electric conductor within the enclosure. A third electric conductor (63) extends outside the enclosure and is attached to an outer surface of a wall of the enclosure. An electrically conductive path is thus provided between the second electric conductor and the third electric conductor through the electrically conductive enclosure.

摘要： The invention relates to a high-voltage fuse comprising a tubular ceramic insulating member (2) that is provided with at least one fusible element, an inner auxiliary cap (3) which is placed on the insulating member (2) and at least partly covers the outer surface of the insulating member (2) in the front area of the insulating member (2), and an outer top cap (4) that is placed on the auxiliary cap (3) and at least partly covers the outer surface of the auxiliary cap (3). The insulating member (2) is provided with at least one depression. The auxiliary cap (3) is molded against the insulating member (2) such that a positive connection to the insulating member (2) is created in the depression. The auxiliary cap (3) and the top cap (4) are molded in the area of said depression in such a way that a positive connection is created. In order to create a high-voltage fuse which ensures that the insulating member is covered so as to be tight towards the outside even at elevated temperatures, a sealing means (5) is provided in the depression while the top cap (4) and/or the auxiliary cap (3) are molded against the sealing means (5) in said depression.

摘要： The subject of the invention is a high-voltage thick-film high rupturing capacity substrate fuse. The characteristic feature of the inventive fuse is that inside a tubular insulating casing /1/, which is closed at both ends with metal endocarps /2/ and filled with arc quenching medium /3/, there is located at least one insulating substrate /4/, along which there is placed at least one fuse element /5/ in the form of a thin conducting film and which has terminal areas /6/ at its ends, which areas are electrically connected with the end-caps by specially shaped contacts /7/ located inside the end-caps. The fuse element comprises a basic part formed by multiple identical V-shaped modules and two end modules forming electric connections between the basic part and the terminal areas. In each module, the arms of the V shape, of a specific width, end with arches directed outwards /8/, which arches are connected with the arches of the arms of the neighboring modules by means of line segments, thus forming a line, which bends many times at a constant angle and has truncated vertices in each module, in which line at least one module contains at least one edge constriction /9/, enabling opening of the current path when the fuse is overloaded.

摘要： Die hier gezeigte Schmelzsicherung (1) hat zwei Anschlußkontakte (2) und einen zwei Teilwicklungen aufweisenden Verbindungsleiter (5), der die beiden Anschlußkontakte (2) verbindet und teilweise als Schmelzleiter (5) ausgebildet ist.
Um eine solche Schmelzsicherung induktivitätsarm und kostengünstig herstellen zu können, so daß sie auch zur Übertragung hochfrequenter Ströme in Hochspannungsnetzen ohne wesentliche Dämpfung der Signalgröße eingesetzt werden kann, sieht die Erfindung vor, daß die zwei Teilwicklungen derart angeordnet sind, daß die Magnetfelder, die von den beiden Teilwicklungen bei einem sich ändernden Stromfluß durch die Schmelzsicherung induziert werden, sich zumindest teilweise auslöschen.

摘要： The fuseholder (50) includes a current limiting fuse mounted within a fuse body (52) and a lower contact and hinge assembly (58). The fuse body has contact assemblies (54,58) mounted on each end thereof. The lower contact assembly on the fuse body is mounted on a hinge (35) which is rotatably supported on an interchangeable cutout mounting (10). 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 (60) rotatably mounted on the interchangeable cutout mounting, a connective member supporting the contact assemblies and fuse body with current limiting fuse, and a latch (62,66) for latching the hinge member to the connective member (64) 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.
