摘要： IMPROVEMENT IN EXHAUST CONTROL DEVICE FOR CIRCUIT INTERRUPTING DEVICES An improvement in an exhaust device to absorb the energy of exhaust gasses released during operation of a circuit interrupting device such as a power fuse or an expulsion fuse is disclosed. The exhaust control device includes a hollow housing coated with a corrosion resistant coating mounted to the circuit interrupting device by means of an adapter, composed of a corrosion resistant material such as brass, which is retained in a counterbore within the housing by rolling or folding over the extended upper rim of the housing so that the coating is not damaged. Alternatively, a steel header, welded to and plated along with the steel housing shell, within which the threaded brass adapter is installed, may also be used. The same rolling or folding operation may be used to secure a plated outlet end wall. Baffles positioned within the housing for partitioning the housing into chambers for cooling and filtering the hot exhaust gases, for changing the direction of flow of the gases and for attenuating sound are held in place by crimping the hollow housing around the baffles so that the plating is not damaged. An annular expansion space formed between the hollow housing and an inner cylindrical shell increases the surface area of the hollow housing which is exposed to the blast of exhaust gases emitted from the fuse and provides an additional expansion chamber for receiving the exhaust gases produced by the interrupting device. A labyrinth plate with circumferential notches formed therein and arcuate ridges formed within and adjacent to said notches, forms gas diverting channels and a labyrinth flow pattern exhaust path to the exit ports formed within an outlet end wall.

摘要： 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 5 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. lilip

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 magnetic field to cause the arcing current to rotate rapidly so as to extinguish the arc as the 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.

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 determini ng 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-li fe may be predicted based upon the cumulative percent of life consumed.

摘要： An electrical path or interconnection arrangement is provided within a forme d support body of polymeric material that exhibits volumetric changes during and after the forming thereof. The electrical path or interconnection arrangement provides an accurately positioned electrically conductive path through the material of the support body and al so responds to, accommodates and alleviates the effects of forces at the interface between t he material of the support body and the electrical path or interconnection arrangement that occ ur during and after the forming of the support body. The interconnection arrangement exhibits predetermined deformability/compressibility characteristics to alleviate stresses caused b y the volumetric changes of the polymeric material. In a preferred arrangement, the interconnection arrange- ment includes an elongated tubular conductor fabricated from a metallic material. The material, the thickness of the tubular walls of the conductor, and the dimensions of the cross- section of the conductor are selected in accordance with the dimensions of t he electrical path and the characteristics of the polymeric material to provide predetermined deform- ability/compressibility characteristics so as to avoid undesirable stress at the interface of the conductor and the polymeric material. In a specific embodiment, the interconnection arrange- ment also provides for the grading of the electrical field about a terminal conductor via the provision of a resilient member that is disposed about the terminal conducto r and also connects one end of a conductor of the interconnection arrangement to the terminal conductor.

摘要： A contact arrangement is provided, e.g. of the type that functions as a wipi ng contact for a moving contact such as a pivotally mounted switch blade in an electrical pow er distribution switch. The contact arrangement in an illustrative embodiment includes space d apart contact members that are biased toward each other to define predetermined contact pressure/force characteristics with respect to the interposed moving contact. The contact members in a preferred embodiment include predetermined contact areas and predetermined structural features to minimize deformation due to magnetic forces experienced in the presence of high currents. The structural features are also arranged to define current paths that increase the contact pressure. In a particular embodiment the contact areas are formed on the contact members so as to minimize the size of the moving contact.

摘要： A low-exhaust composite drop-out assembly (10) is provided that is utilizable in a standard cutout mounting (12) in electrical power distribution systems. The composite drop-out assembly (10) includes current-limiting (16) and low-current clearing (14) sections and is easily removable from the mounting (12) for servicing. The sections (16,14) are efficiently arranged in a side by side configuration. The low-current clearing section (14) includes a fuse-tube assembly (15) having a replaceable fuse cartridge (52). Accordingly, the low-current clearing section (14) is simply and economically renewable for reuse whether or not the current-limiting section (16) has operated. Further, the current-limiting section (16) need not be replaced if only the low-current clearing section (14) operated in response to overcurrent in a low range. Additionally, the sections (14,16) include separable provisions so that the separable portions of the low-current clearing section (14) can be reused after simple refusing even when the current-limiting section (16) has operated.
