Problems solved by technology

[0006] However, at present, the setting position, method and principle of the magnetic valve of the magnetic control reactor are often only based on experience, and the performance of the magnetic control reactor produced by different manufacturers is quite different. The specific effect is unsatisfactory due to problems such as high-order harmonics with too much content

Abstract

The invention provides a magnetically controlled reactor and a method. Magnetic valves are arranged on one or more pairs of ironic core pillars with coils, under the condition that the shape and sizeof the magnetic valves are set to be capable of making a magnetized curve of an ironic core of the magnetically controlled reactor formed by sequentially connecting line segments a1, a2 and a5, wherein a1 is the starting point of the magnetized curve, and corresponding magnetic induction intensity is zero; a2 is a point between the starting point of the magnetized curve and a knee point, and magnetic induction intensity B2 corresponding to a2 is between magnetic induction intensity corresponding to zero and magnetic induction intensity corresponding to the knee point; magnetic induction intensity corresponding to a5 is equal to that corresponding to the knee point, and is the peak value of the maximum value of reactance current of the magnetically controlled reactor. By designing the magnetic values, the ideal magnetized curve of the ironic core of the magnetically controlled reactor can be obtained, so that the content of higher harmonic of the magnetically controlled reactor is minimum.

Description

technical field [0001] The present disclosure relates to a magnetron reactor and a method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Reactors are widely used in power systems. In some application fields, the reactance value of the reactor is fixed; while in other application fields, the reactance value of the reactor should be adjusted continuously with the change of the power system operation mode. The controllable reactor whose reactance value can be adjusted continuously is an important research topic. [0004] The magnetron reactor (also known as: saturable reactor) utilizes the non-linear characteristics of the magnetization curve of the closed-loop iron core to adjust the saturation degree of the closed-loop iron core by continuously adjusting the magnitude of the DC current in the DC coil on the closed-loop iron core, and r...
