Abstract

The invention provides an iron core structure, an iron core reactor and a method thereof. The iron core air gap structure composed of an iron core cake and an air gap cushion block of an existing ironcore reactor is replaced by a magnetic valve, so that vibration and noise effects during operation caused by the existing air gap structure can be reduced on the basis of maintaining the linear characteristics of the iron core reactor. By using the air gap at the magnetic valve, the magnetic flux will flow through the air gap to ensure the linearity at least for a certain period of time when theiron core is in operation. At the same time, because the iron core column in the coil of the iron core reactor is uninterrupted, the iron core cake and the air gap cushion block are not needed, the vibration and the noise of the iron core reactor in the operation process are small.

Description

technical field [0001] The present disclosure relates to an iron core structure, an iron core 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 order to increase the reactance value of the reactor, an iron core can be added to the reactance coil. In order to obtain the linear characteristics of a reactor with an iron core, the reactor iron core needs to add an air gap. However, the existing air gap structure of the reactor iron core is composed of an iron core cake and an air gap spacer. Because the iron core cake and the air gap Due to the structural characteristics of the block, the iron core reactor with this structure has the problems of large vibration and large noise during operation. Contents of the invention [0004] In order to solve the above problems, the pr...
