Filter reactors are used in low-voltage filter cabinets, connected in series with filter capacitors, and tuned to a certain resonant frequency to absorb harmonic currents of corresponding frequencies in the power grid. There are a large number of harmonic sources such as rectifiers, converters, and frequency converters in the low-voltage power grid, and the high-order harmonics generated by them will seriously endanger the safe operation of the main transformer and other electrical equipment in the system. After the filter reactor is connected in series with the capacitor, it can not only effectively absorb the harmonics of the power grid, but also improve the power factor of the system, which plays a great role in the safe operation of the system.
Structural features | |
phase | The reactor is divided into three-phase and single-phase two, both are iron core dry type |
iron core | The iron core is made of high-quality and low-loss special materials. The core column is divided into uniform small sections by multiple air gaps. The air gaps are separated by epoxy laminated glass cloth boards and bonded with special adhesives to ensure that the reactance air gaps are in the process of operation. no change |
coil | The coils are wound with class H or class C enamelled flat copper wire or copper foil, arranged closely and evenly |
Reactor | The coil and iron core of the reactor are assembled into one body and then go through the process of pre-baking→vacuum dipping→heat-baking and curing, and the H-level dipping varnish is used to firmly combine the coil and the iron core of the reactor. |
clip | The clips and fasteners of the reactor are made of non-magnetic materials to ensure that the reactor has a high quality factor and a good filtering effect. |
Exposed parts | The exposed parts are treated with anti-corrosion treatment, and the lead-out terminals are made of tinned copper tube terminals |
