Product Overview
The high-voltage reactor -HRDKC is mainly used in 6kV to 35kV power systems in series with high-voltage capacitor banks. It can effectively suppress and absorb high-order harmonics, limit inrush current and operating overvoltage during closing, protect capacitor banks, improve the voltage waveform of the system, and enhance the power factor of the power grid.
Product features
The reactor adopts a unique insulation structure, which significantly enhances the insulation level of the product. It can meet the high withstand voltage requirements of power standards and the insulation requirements at high altitudes, solving the problem of generally low withstand voltage of traditional iron core reactors.
Both the core column and the iron wheel are vacuum-cast and sealed with epoxy resin. There are no gaps inside the core and it is bonded into a whole with epoxy resin, which effectively reduces the noise during the operation of the reactor. The core column adopts a radiating laminated or infinite stepped structure. At the non-magnetic gap, the transverse leakage magnetic flux of the core column does not pass vertically through the plane of the iron chip, thereby greatly reducing the additional loss of the core.
The high-voltage coil is at the same potential as the core column, which can reduce the distance between the coil and the core column, decrease the average diameter of the coil, reduce the volume of the reactor, and thereby lower the weight and line loss of the reactor.
