Description

Technical Field

[0001] The utility model relates to the technical field of iron core structures, in particular to a synchronous adjustment resonant reactor split iron core structure. Background Art

[0002] The split iron core structure of a reactor is a quite common iron core structure in power equipment, especially common in inductance-adjustable resonant reactors. By adjusting the position of the iron core in the coil, the inductance is changed, so as to realize the adjustment of the circuit, and it is widely used in fields such as power systems, electronic devices, and communication systems for adjusting current, voltage, reactive power, etc.

[0003] In different working scenarios, the circuit may require different inductance values to achieve functions such as filtering, resonance, and reactive power compensation. The fixed position of the iron core means that the inductance is fixed, which limits the application range and adaptability of the reactor. In a circuit with harmonics, the inability to adjust the iron core position may not effectively suppress the harmonics, resulting in a decline in power quality, which in turn affects the normal operation of various devices connected to the circuit. The decline in power quality will also increase the losses of the devices, causing the devices to generate more heat during operation, accelerating the aging and wear of the devices.
