Abstract: The invention provides a high performance circuit breaker with an independent pole operation linkage and conical composite bushings. A mechanical linkage for independently opening and closing a plurality of associated switches is provided by the invention. The linkage comprises a plurality of connecting rods (32-34) that provide the initial driving force to open or close the switches, cranks (50) for opening and closing the contacts (12, 14, 15, 19) of respective switches, linking elements (36-39) which couple together the connecting rods (32-34) and the cranks (50), and a number of lever assemblies (40, 41) having a bearing ring (45, 46) interfaced thereto. The bearing rings (45, 46) provide a supportive interface between two linking elements (36-39) but permit the linking elements (36-39) to rotate independently from one another. The lever assemblies (40, 41) also provide an interface for the connecting rods (32-34) and linking elements (36-39). The present invention also includes a method of operation of the circuit breaker through the independent pole operation linkage.

Abstract: A silicon transfer switch (10) having a compact and modular arrangement of solid state switch components (14) within the switch boxes (10). The components are arranged in modular half-stack assemblies (14) such that the half-stacks can be loaded into and out of compartments (12) within the switch boxes (10) in an efficient and timely manner. The cooling system minimizes temperature and pressure gradients in the flow of air to the electronic components arranged in the stacks (14) so as to provide uniform cooling of the components. The compact and modular arrangement of the switch components optimizes electrical interconnection between components, mechanical clamping forces, thermal cooling, magnetically coupled solid state switch device firing and temperature management within the system.

Abstract: A solid state voltage regulator (10) and methods therefor are shown to include a transformer (18) having a secondary coil, the secondary coil having a plurality of taps (20, 22, 24, 26, 28, 30, 32). A first solid state switch (34) is connected between the regulator output (14) and a first tap (20). The first switch (34) need only have the capability of being turned on in response to a gate signal. A second solid state switch (36) is connected between the regulator output (14) and a second tap (22). The second switch (36) has the capability of being turned on and turned off in response to gating signals. The output voltage resulting from the second tap (22) is greater than the first tap (20). A controller (16) connected to the input (12), the output (14), the first switch (34) and the second switch (36) senses the voltage present at the regulator input (12) and output (14) and generates gating signals in response to the sensed voltage. The voltage regulator (10) may include several switches (38-46) similar in construction and operation to the first switch (34). In such a regulator, the second switch (36) is connected to the tap (22) which results in the coil turn ratio yielding the greatest voltage compensation.

Abstract: An operating mechanism for a combined interrupter and disconnect switch (10, 11) comprises an operating linkage (17) and an interrupter support housing (41) rotated separately about a common pivotal axis. The interrupter switch (10) is part of a disconnect switch arm and is secured to the support housing. The interrupter contacts are operated by a linearly movable rod (40) which has an end connected to a lever (56) extending from the operating crank (55) and is movable thereby. A linearly movable operating shaft (21) is connected to and moves a crank arm (57). A spring biased latch lever (80) is pivotally mounted to the interrupter support housing and releasably engages the free end of the crank arm lever (56) so that the housing rotates with the crank and closes the disconnect switch (11). When the disconnect switch closes, the latch lever (80) releases and the crank (57) rotates relative to the housing to operate the linearly movable rod (40) which operates the interrupter switch (10).

Abstract: Methods and apparatus for metering electrical energy are disclosed in an electronic meter which includes a first oscillator for generating a first clock signal within a first accuracy and a second oscillator for generating a second clock signal within a second accuracy. A processor, operable in relation to a clock signal, measures time and periodically compensates for the accuracy of the first oscillator. The first clock signal is used for measuring time when power is applied to the meter and the second clock signal is used by the processor for measuring time when power has been removed from the meter. The accuracy of the first oscillator is compensated periodically in relation to a compensation factor stored in memory. In one embodiment, the processor includes a counter for counting from a first value to a second value in response to the first clock signal. In such an arrangement, the processor substitutes the first compensation factor for the first value. The meter can further include a timer, wherein the processor substitutes the first compensation factor for the first value in response to the first timer. The processor also is shown to implement a process for compensating for the accuracy of the second oscillator. This process compensates for the accuracy of the second oscillator in relation to the first oscillator. To this end, the process calculates a second compensation factor. The second compensation factor is determined when power is applied to the meter, wherein after power has been removed and restored, the second compensation factor is used to compensate time measured in relation to the second oscillator during the period power had been removed.

Abstract: Methods and apparatus for switching a load between first (P) and second sources (A) is shown to include first (32) and second (42) solid state switches connected to the load. First (30) and second (40) mechanical breakers are connected between the switches and the sources so that each source is connected to the load through a circuit breaker and solid state switch. A controller (50) is connected to sense the voltage from the first (P) and second (A) sources. The controller (50) is connected to the first (32) and second (42) switches and the first (30) and second (40) mechanical breakers. The controller (50) senses the phase difference from the voltages from the first (P) and second (A) sources. The controller (50) causes the first (30) and second (40) mechanical breakers to open and close in response to sensing the phase difference between the sources. The first (30) and second (40) mechanical breakers can include medium voltage vacuum breakers. In a preferred embodiment, when the controller (50) senses that the phase differences between sources is more than 30 degrees out of phase, the controller (50) will open the circuit breaker (40) connected to the alternate source (A). In this manner voltages stress on the solid state switching devices is minimized.

Abstract: Apparatus for detecting the direction of a fault in relation to a switch (14) connected between a source (10) and a load (16) includes a voltage sampler and a current sampler for generating voltage and current samples during first and second power cycles. A first comparator (66, 68, 70) compares the current samples from the first and second cycles and determines the sign of the difference between the samples. A second comparator (72) compares the sign of the voltage from the first cycle to the sign of the current difference determined by the first comparator and provides an indication of fault direction. The apparatus also includes a fault inception determiner (46, 50) for providing a fault inception indication determined by comparing the voltage samples from the first and second cycles and detecting the sign of the difference between the samples.
