Problems solved by technology

[0002] The traditional shell-type iron core reactor has an air gap at the joint of the iron core. When the reactor is energized and running, the air gap will generate a lot of noise due to the attraction of the iron core and the hysteresis of the iron core sheet, especially the large harmonic content. In systems where noise is often difficult to control
The traditional air-core reactor has a large magnetic flux leakage, and the mutual interference is large when multi-channel integration

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] figure 1 , figure 2 , image 3 and Figure 4 An embodiment of the present invention is shown. The wound core shell reactor of this embodiment includes a coil assembly 1, the coil assembly 1 is wound with a wound core 2, and the inner wall of the wound core 2 is provided with a hole for eliminating the air gap of the wound core 2. Pouring layer 3.

[0024] The wound core shell reactor of the present invention wraps the wound core 2 outside the coil assembly 1 to form a wound core shell reactor. The inner wall of the wound core 2 is provided with a pouring layer 3 so that the wound core 2 forms a whole. In the entire magnetic circuit There is no air gap and almost no saturation, which effectively avoids the noise caused by the iron core suction at the air gap and the hysteresis expansion and contraction of the iron core shee...

Abstract

The invention discloses a wound core shell type electric reactor. The electric reactor comprises a coil assembly, wherein a wound core is wound around the outside of the coil assembly, and the inner wall of the wound core is provided with a pouring layer used for eliminating the air gap of the wound core. The electric reactor has the advantages of being low in noise, almost not saturated, small inmagnetic flux leakage, capable of achieving multi-path integration and application, small in interference and the like.

Description

technical field [0001] The invention relates to a reactor, in particular to a wound core shell reactor. Background technique [0002] The traditional shell-type iron core reactor has an air gap at the joint of the iron core. When the reactor is energized and running, the air gap will generate a lot of noise due to the attraction of the iron core and the hysteresis of the iron core sheet, especially the large harmonic content. In the system, the noise is often difficult to control. The traditional air-core reactor has a large magnetic flux leakage, and the mutual interference is large when multiple channels are integrated. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a wound core shell reactor with low noise, almost no saturation, low flux leakage, multi-channel integrated use and low interference. [0004] In order to solve the problems of the technologies descr...
