Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a temperature-automatically controlled low-noise dry-type air-core reactor. Background Art

[0002] Reactors are also called inductors. When a conductor is energized, it will generate a magnetic field in a certain space it occupies. Therefore, all current-carrying conductors have inductance in a general sense. According to the structure and cooling medium: they are divided into hollow type, iron core type, dry type, oil-immersed type, etc.

[0003] Reactors are widely used in power electronic components. Although the outer shell of the dry-type reactor is set with a gap, the heat dissipation effect of the internal magnetic core is still poor during use, and dust and impurities are easily accumulated in the internal gap of the reactor during use, affecting the overall heat dissipation effect. For this reason, we propose a temperature-controlled low-noise dry-type air-core reactor to solve the above problems. Utility Model Content
