Abstract:
The approaches described herein can provide mitigation against the risk of one or more malfunctions of electronics of a negative pressure wound therapy device. The one or more malfunctions can include flow reverse current, flow of excessive current, liquid ingress, or inadvertent activation. The approaches described herein can provide protection against a single fault (or higher protection against more than one fault). Advantageously, mitigation against the risk of burning or otherwise causing discomfort to the patient or the risk of fire can be provided.
Abstract:
A fuse for a battery module is provided. The fuse includes a fusing element having a plurality of openings, a first fuse link that is integrally formed with a first portion of the fusing element, a second fuse link that is integrally formed with a second portion of the fusing element, and an overmold that encapsulates at least a portion of the fusing element. The second portion of the fusing element is arranged opposite to the first portion of the fusing element. The first fuse link may be configured to connect to a first battery cell of a battery module and the second fuse link may be configured to connect to a second battery cell of the battery module.
Abstract:
The invention relates to a power distribution unit (1), such as a fuse box for a vehicle, for providing a protected electrical connection between a power supply cable and a plurality of distribution cables (7). The unit comprises a housing (2) and, received in said housing: -a bus bar (5) configured to be connected to the power supply cable; -a plurality of fuses (10), each fuse comprising a body (15), a first end portion (11) configured to be connected to the bus bar (5), and a second end portion (12) configured to be connected to a distribution cable (7); -at least one retainer (20) for maintaining the bus bar (5) in position with respect to the housing (2); -at least one positioner (40) for positioning the fuse first end portion (11) relative to the bus bar (5) along directions (X,Y) substantially parallel to the bus bar; -a biasing member (30) configured to urge the fuse first end portion (11) towards the bus bar (5), to cause the fuse first end portion to remain in contact with the bus bar.
Abstract:
L'invention concerne un dispositif de coupure pyrotechnique (1) comprenant un premier (21) et un deuxième (22) initiateurs pyrotechniques, et un corps (10) dans lequel sont présents : une portion conductrice de l'électricité (40), et un élément de coupure mobile (30) présentant un relief isolant (33) en regard de la portion conductrice. Le dispositif comprend en outre un élément fusible (50) relié en série à la portion conductrice (40), le premier initiateur (21) étant relié aux bornes de l'élément fusible (50) de sorte qu'un déclenchement de l'élément fusible actionne le premier initiateur, chaque initiateur (21, 22) étant configuré pour faire passer le dispositif d'une configuration de passage du courant à une configuration de coupure du courant, l'élément de coupure mobile (30) étant mis en mouvement vers la portion conductrice (40) afin de la rompre par impact avec le relief (33) lors du passage de la première à la deuxième configuration.
Abstract:
Die Erfindung betrifft eine Sicherung (6) zur Anordnung in einer elektrischen Versorgungsleitung (5) eines Verbrauchers (4), wobei die Sicherung (6) ein Sicherungselement und eine Halterung für das Sicherungselement umfasst. Es ist ein Mittel (8) zur Veränderung der Kennlinie und/oder zur Beeinflussung der Auslösecharakteristik für das Sicherungselement vorgesehen.
Abstract:
A programmable fuse (100) and fuse panel (1000) are described. Unlike conventional fuses and fuse panels, the trip values of the fuses (100) of the panel (1000) - i.e., the current values at which the fuse (100) trips - are field programmable. On of many advantages includes the ability to adaptively set the trip value of a fuse (100) - depending on the operating needs of a load device (130) - without having to physically exchange the fuse (100) In an embodiment, electronic fuses (110) are used.
Abstract:
Um einen Sicherungsanbau (1) für eine Mittelspannungsschaltanlage mit einer Sicherungskammer (2) und einem Sicherungseinschub (3) zur Aufnahme einer Sicherung und eines Sicherungsstößels (4), weiterzubilden, welcher bei einer einfachen Konstruktion eine verbesserte Dichtung aufweist wird vorgeschlagen, dass der Sicherungsanbau (1) über wasserdichte Dichtungsmittel (7, 8, 9, 11, 12, 13) zwischen der Sicherungskammer (2) und dem Sicherungseinschub (3) sowie im Austrittsbereich des Sicherungsstößels (4) aus dem Sicherungseinschub (3) verfügt.
Abstract:
A fuse for a high voltage/high current application, such as a hydro-electric vehicle ("HEV") application is provided. The fuse employs a variety of arc quenching features to handle a large amount of arcing energy that is generated when such fuse is opened due to a fuse opening event. In one embodiment, an insulative substrate, such as a melamine substrate, is metallized with a fuse element. The fuse element extends to multiple surfaces of the substrate. A fuse opening portion of the element is located so that the arcing energy is forced to travel along multiple insulative planes, increasing an impedance across the opening of the element and decreasing the likelihood of a sustained arc. Also, the substrate and element are disposed in a sealed housing, which is packed in one embodiment with an arc quenching material, such as sand.
