Embodiment Construction

[0016] Embodiments of the invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some embodiments are shown. However, the subject matter of the present disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the subject matter to those skilled in the art. In the drawings, like reference numerals refer to like elements throughout.

[0017] Various embodiments described herein provide an FCL that includes a current splitting reactor (CSR) with interleaved windings. Furthermore, the current shunt reactor may have an open core design. FCLs comprising CSRs with interleaved windings advantageously provide low insertion resistance. As an example, the FCLs described herein may have an insertion impedance of less than 1% of the total...

Abstract

In one embodiment a fault current limiter comprises a current splitting reactor having interleaved windings to reduce an insertion impedance of the fault current limiter during non-fault conditions. The current splitting reactor having interleaved windings may include a first winding, the first winding including a plurality of sub-windings and a second winding, the second winding including a plurality of sub-windings, the sub-windings of the first winding and the sub-windings of the second winding wounds about the core and interleaved.

Description

[0001] The present invention is a divisional application. The filing date of the original application is: November 20, 2014; the original application number is: 201480071590.5; the original invention name is: power system and error current limiter with interleaved windings. technical field [0002] The present invention relates to current control devices and, more particularly, to power systems and faulty current limiters with interleaved windings. Background technique [0003] A fault current limiter (fault current limiter, FCL for short) is used, for example, to provide protection against current surges in a power transmission network. In the past decades, various types of FCLs have been developed, including superconducting fault current limiter (short: SCFCL), solid state fault current limiter, inductive fault current limiter and all in this technology. Various other error current limiters are known. The power system in which the FCL is implemented may include generation...
