Current controlling device

Abstract

There is described a device for controlling an amount of current within a power distribution network by manipulating the amount of magnetic flux in the device and thus the impedance experienced by thepower distribution network across the device. This is achieved by winding a plurality of coils about a magnetically permeable core and by providing the device with a magnetically permeable bridge element that is movable between a fully-open position at which the net magnetic flux generated in the core by alternating currents in each coil is zero, and a fully-closed position at which a net magnetic flux is present in the core.

Description

technical field [0001] The techniques described herein relate to current control devices. In particular, an apparatus for controlling current in an N-phase power distribution system during fault conditions is described. Background technique [0002] Power systems are used to generate and supply electricity. An example of such a system is an electrical grid that generates and provides power to an extended area. Smaller power systems can also be realized on aircraft and marine vessels, etc. [0003] A power system typically includes a generator set and a power distribution system that feeds the generated power to nearby electronic components throughout the power system. A power distribution system typically includes a plurality of distribution lines for supplying alternating current (AC) or direct current (DC) to electronic components and one or more return lines serving as return paths for the current. [0004] A known problem with power systems is that power distribution...

Problems solved by technology

[0006] However, the problem in such systems is that they are bulky in size (for example, in that they have parallel circuits) and often require repair and replacement of components after a failure
