Description

Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to a three-phase high-frequency magnetic powder core reactor clamp. Background Art

[0002] High-frequency reactors are reactors with operating frequencies exceeding medium frequency (10kHz). They are mainly used in high-frequency switching power supplies. The rectifier input circuit in the variable speed drive will generate current ripple, affect the DC capacitance of the inverter, and generate harmonic distortion in the power grid. They are also used as high-frequency inverters in high-frequency inverter power supplies and high-frequency inverter welding machines. In high-frequency power systems, three-phase high-frequency magnetic powder core reactors require a compact clamp structure to ensure their stability under conditions such as vibration, thermal expansion, and electromagnetic interference. Traditional clamp structures have problems such as complex installation and insufficient reliability. Traditional clamp structures usually require complex steps to install and clamp the reactor components, which may require more time and professional skills, and due to insufficient clamping force of the clamps, the reactor components are easily affected by external vibrations, which may lead to performance degradation or failure.

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] See also Figure 1 The utility model provides a technical solution: a three-phase high-frequency magnetic powder core reactor clamp, including a first iron core 1 and a second iron core 2, three coils 3 are arranged between the first iron core 1 and the second iron core 2, core columns 4 are arranged in the three coils 3, and pull plates 5 are arranged on both sides of the core columns 4. An upper clamp 6 is arranged on the first iron core 1, and a lower clamp 7 is arranged on the second iron core 2. The two ends of the pull plate 5 are respectively connected to the upper clamp 6 and the lower clamp 7. An upper connecting groove 8 is arranged on the upper clamp 6. There are two upper connecting grooves 8, which are arranged in parallel along the length direction of the upper clamp 6, and the two upper connecting grooves 8 are vertically connected to the upper clamp 6.
