The balanced reactor uses the entire E-type structure of the amorphous alloy as the magnetic core, which eliminates the adverse effect of excessive high-frequency loss of the ordinary iron core structure reactor. In addition, the magnetic core is divided into two parts, the core air gap is improved, and the local overheating phenomenon of the original reactor stamping sheet structure is reduced. The effective combination of output reactor and filter loop reactor, in addition to suppressing system harmonics and improving the quality of the power grid, can also be used for three-phase dynamic balancing in the line, in order to adjust equipment that easily causes three-phase misalignment. Balanced reactors are suitable for environmental applications where industrial applications such as electrolytic plating often require low voltage and high current (for example, tens of volts, thousands to tens of thousands of amps) of adjustable DC power.

1. Can be used in 380V ~ 1000V systems.
2. Rated insulation level is 3kV / min.
3. Temperature rise limit of each part of the reactor: the temperature rise of the iron core does not exceed 85K, and the temperature rise of the coil does not exceed 95K.
4. Reactor noise meets relevant international requirements.
5. The reactor can run for a long time under 1.2 times the rated voltage.
6. Temperature resistance class F.
1. The reactor has a single-phase structure and a core dry type.
2. The core is made of high-quality low-loss cold-rolled oriented silicon steel sheet. The core is divided into uniform small sections by multiple air gaps. The air gap is made of epoxy laminated glass cloth sheet and the high temperature and high strength adhesive is used to ensure the reactance air gap Does not change during operation.
3. The coil is wound with oxygen-free copper wire or copper foil, arranged tightly, with F-level insulation between the layers and the surface.
4. After the coil and core of the reactor are assembled into one body, the process flow is pre-baking → vacuum dipping paint → hot-baking curing, using F-level dipping paint. The coil and iron core of the reactor are firmly combined to ensure no noise when running at high temperatures.
5. The fasteners in the main magnetic circuit of the reactor are made of non-magnetic materials to ensure that the reactor has lower power consumption and temperature rise.
6. The exposed terminals use tin-plated copper bars or cable terminals to ensure reliable contact; clips and other parts have been treated with anti-corrosion treatment such as galvanizing or painting to ensure that they do not rust.
Balanced reactors are suitable for industrial applications such as electrolytic plating, which often require low voltage and high current adjustable DC power supplies. The operating conditions of the double-reverse star-band balanced reactor rectifier circuit in the laboratory, especially in the thermal engineering laboratory, are complex and changeable. Therefore, the output adjustment range of the rectifier circuit is generally required to be large and repeatable.
