The invention discloses an electric reactor used for a variable-frequency air conditioner. The electric reactor comprises a skeleton, a coil winding wound around the skeleton and an ironic core assembled with the skeleton. The skeleton is provided with a rectangular window, the ironic core is composed of an E-type ironic core body and an I-type ironic core body which are assembled together, the E-type ironic core body is provided with a center pillar and side pillars, the center pillar is inserted into the rectangular window in the skeleton, air gaps are formed between the end faces of the side pillars and the I-type ironic core body and filled with air gap pieces, and the electric reactor further comprises an annular iron shell located on the outer side of the annular direction of the skeleton, wherein the iron shell wraps the skeleton and the ironic core. The air gaps between the end faces of the side pillars and the I-type ironic core body are formed and filled with the air gap pieces, and by adjusting the thickness of the air gap pieces, different demands for inductance values are met.
Description
technical field [0001] The present invention relates to reactors. Background technique [0002] Inverter air conditioners rectify AC mains electricity into DC electricity, and then invert it into AC electricity with adjustable frequency and voltage, because there are high harmonic AC components in the AC voltage of the power grid and the rectified DC voltage; , there are also a lot of high-frequency harmonic components, which will increase the noise and loss of the motor. The way to filter out these harmonics is to connect the reactor in series. This characteristic of low resistance is realized. [0003] At present, the reactors on the market usually adopt a frameless coil structure, and the silicon steel sheet needs to be welded by argon arc, which leads to high cost, low production efficiency, and difficulty in ensuring safety. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a reactor for an inverter air cond...
