摘要： Different configurations of transient voltage quashing (TQ) transformers, harmonic current quashing (HQ) transformers, and transient voltage and harmonic current quashing (THQ) transformers include one or more of: a tertiary winding radially placed between the primary and secondary windings, with a surge suppressors coupled thereto, which quashes transient voltages in the transformer and any output device attached to output leads of the tertiary or secondary windings; and an arrangement of the secondary windings, separated by at least a second type intra-winding insulation, into one or a plurality of output winding groups, each used to provide power to N serially-connected output devices that exhibit known/expected output voltage characteristics. The second type intra-winding insulation has a dielectric strength to withstand the sum of the voltage output of the device being powered by the output winding and the adjacent serially-connected device, such that the output device experiences minimal harmonic currents.

The transformer coils are wound in three separate, multi-wound windings on three single-phase cores. A vector oriented winding scheme is provided with three output windings and three internal zig-zag configured pairs of windings. The three internal zig-zag windings are connected at corresponding ends of a first winding to form an electrical neutral. The second windings of the three internal zig-zag windings respectively tap one of the output windings.

In each phase of one implementation, two contactor poles are in series between split sections of a secondary winding of a transformer.

摘要： An apparatus for controlling electrical characteristics in an alternating current system includes a first level of magnetic amplifiers which are responsive to a primary direct current control signal. The magnetic amplifiers provide secondary control signals in response to the primary control signal. The secondary control signals control a second level which includes a magnetic amplifier having gate windings to which the alternating current to be controlled is connected. Depending upon the nature of the primary control signal, the current magnitude or voltage magnitude of the alternating current can be controlled, both in relation to other alternating currents and in relation to a predetermined current or voltage magnitude.

摘要： A method, device, and plurality of circuit enhancements for a rectifier system that enable reduction in lower order and higher order harmonics, without substantially reducing the rectifier's direct current output voltage. The rectifier system comprises a phase shifting primary transformer subsystem and a multi-pulse rectifier. At least one series impedance path is coupled to one of three input terminals/leads of the transformer subsystem and conducts one phase of three phase currents from a power supply to the transformer subsystem. The series impedance path provides low impedance to the 1st harmonic and substantially higher, inductive impedance to higher harmonics of the power supply frequency. The impedance of the series impedance path at a selected frequency above a third harmonic of the power supply's fundamental frequency divided by the impedance at the fundamental frequency of the three phase power supply is substantially greater than the selected frequency divided by the fundamental frequency of the power supply.

摘要： A three-input induction transformer in which the phase relationship of the power output relative to the power input is selectable/adjustable after the transformer is placed in operation in the field. The transformer includes a primary set of windings and a three-pole, selector mechanism attached to the windings and which configures the windings in one of multiple serial configurations based on the selected position of the selector mechanism. Each transformer is configured so that the output-to-input phase relationship rotates a pre-determined number of degrees when the connectivity of the three-pole selector mechanism is changed.

摘要： A three-phase transformer includes six windings, disposed in three pairs, all of which six windings are serially interconnected. A desired turns ratio between the two windings of each pair establishes a desired phase shift between one three-phase output of the connected windings and a second three-phase output of the windings. These two windings can be used in combination to drive a load, such as an induction motor, such as through a twelve pulse rectifier requiring two three-phase outputs out of phase by 30.degree.. Alternately, one of the three-phase outputs can be used to supply the full load of the motor directly. This is particularly useful in a electric submersible pumping system having a three-phase induction motor which is normally operated by a maintenance intensive twelve-pulse rectifier, which motor needs to be directly driven through a by-pass motor controller when the rectifier is in maintenance.

摘要： A motor control system includes a single, multicompartment enclosure mounted on a skid. The enclosure contains a transformer circuit and a motor controller circuit interconnected so that only external connections to a power source and a load are heeded. When the circuits are energized, access to high voltage motor control components and to field replaceable fuses and output selection switches is provented by a double interlocking mechanism which operates in conjunction with energizing and de-energizing the transformer. The transformer of the transformer circuit includes a tertiary winding disposed radially between a primary winding and a secondary winding. The winding filters electrostatically coupled transients. A conventional electrostatic shield is also used so that the transformer is doubly shielded to electrostatic transients. The tertiary winding is connected to one or more capacitors to filter magnetically coupled transients. A current limiting fuse, a load sensing fuse and a primary make/break switch are connected in electrical series to the primary winding. Methods for energizing or operating a motor utilizing the primary switch and the load sensing fuse are also disclosed.
