高耦合分裂电抗器的设计和仿真

Design and Simulation of High Coupling Split Reactor

高耦合分裂电抗器、单臂限流电感、双臂间耦合度、选用的断路器弧阻大小等因素是影响并联型断路器均流效果的主要因素。采用“高耦合电抗器+真空断路器并联”方案,能有效实现自动均流和限流功能,从而成倍增大断路器承受额定电流和短路电流的能力。文章主要讲述了“高耦合电抗器+真空断路器并联”的原理和高耦合电抗器研制过程中的问题及解决方案。

Factors such as high coupled split reactor,single-arm current-limiting inductance,coupling between two arms,and the selected circuit breaker arc resistance are the main factors that affect the current sharing effect of parallel circuit breakers.The use of"high coupling reactor+vacuum circuit breaker in parallel"scheme can effectively realize the automatic current sharing and current limiting functions,thereby doubling the circuit breaker’s ability to withstand the rated current and short-circuit current.This article mainly describes the principle of“high coupling reactor+vacuum circuit breaker in parallel”and the problems and solutions in the development process of high coupling reactor.
