摘要： A fault interrupting and reclosing device includes a circuit interrupter coupled to an actuator. The actuator includes at least one force generating element for generating an opening force for opening the circuit interrupter and for generating a restoring force to close the circuit interrupter. The device further includes a latch to engage the actuator to hold the contacts open once opened. In a preferred arrangement, the device is provided with an automatic mode of operation including a reclose process and a non-reclosing mode of operation. The device also preferably includes a method of determining the end-of-life of a vacuum interrupter monitors characteristics and/or parameters of a fault current or vacuum interrupter operation to predict a percent of life consumed with each fault current interruption operation. A cumulative percent of life consumed may also be determined, and an end-of-life may be predicted based upon the cumulative percent of life consumed.

摘要： Coupling apparatus is provided for assembly with separable insulated connect or components on power cables for power distribution systems. The coupling apparatus provides either direct or indirect coupling, e.g. to provide interconnection to the connector components or to provide a sensing point. In one illustrative embodiment, the coupling apparatus is installed in place of a conventional double-ended plug that is required to piggyback T-bo dy elbows, i.e. where multiple elbows are to be connected. In one specific arrangement, the coupling apparatus includes a desired connector interface. In another specific arrangement, a sensed voltage output is provided using components such as capacitive coupling components, capacitors , resistors or transformers. In another embodiment, the coupling apparatus is used in place of a conventional insulating plug that is used to attach a T-body elbow to a bushing, e.g. on switchgear assemblies or the like. In a specific arrangement, the coupling apparatus is a voltage sensor and provides a sensed voltage output derived from a capacitive coupling arrangement utilizi ng a capacitive divider. In a preferred form, the voltage sensor also encapsulates circuitry to provide a low impedance output signal that is directly proportional to the sensed voltage.

摘要： An improved switch for a high-voltage device in which ignition of a power cartridge moves an insulative piston located in a conductive member away therefrom and into a passageway in an insulative liner. The piston moves a contact through the passageway and away from the conductive member to break an electrical interconnection between the conductive member and the movable contact, thereby opening the switch. The switch includes an insulative housing engageably surrounding, holding and fixing the relative positions of the conductive member and the liner. An interiorly relieved extension is formed at and about one end of the liner, and an exteriorly relieved region is formed in and about one end of the conductive member, whereby the region may be telescoped into and conformally engage the inside of the extension so that the conductive member and liner partially overlap along a tortuous interface so as to increase the interrupting capability of the switch by enhancing the isolation between the power cartridge and the passageway.

摘要： A low-exhaust composite drop-out assembly is provided that is utilizable in a standard cutout mounting in electrical power distribution systems. The composite drop - out assembly includes current-limiting and low-current clearing sections and is easily removable from the mounting for servicing. The sections are efficiently arranged in a side by side configuration. The low-current clearing section includes a fuse-tube assembly having a replaceable fuse cartridge. Accordingly, the low-current clearing section is simply and economically renewable for reuse whether or not the current-limiting section has operated. Further, the current-limiting section need not be replaced if only the low-current cleari ng section operated in response to overcurrent in a low range. Additionally, the sections are separable so that the low-current clearing section can be reused after simple refusing even when t he current-limiting section has operated.

摘要： A rotating arc fault-current interrupter, also known as an arc spinner interrupter, is provided that establishes an easily visible open gap via a movable blade member having a first portion for engaging a stationary main contact and a second portion formed by an arcing electrode for engaging an auxiliary contact associated with an arc spinner assembly. The geometry, orientation and placement of the auxiliary contact is such that during opening of the movable blade member, the arcing electrode remains engaged with the auxiliary contact after the blade member and the stationary main contact are separated from each other whereby current is transferred through the auxiliary contact into the arc spinner assembly, i.e. the current is commutated into the arc spinner assembly. Thus, the current in the arc spinner creates a magneti c field to cause the arcing current to rotate rapidly so as to extinguish the arc as th e arcing electrode separates from the auxiliary contact and moves to the opened position whereby a visible open gap is established that is easily visible without any obstructions from a range of viewing angles or orientations.
