High-voltage - Import export

In power electronics in general, and especially in low inductance buffer circuits with higher voltages as well as in discharge circuits, the call for capacitors with low inductance tends to pose problems: traditional high voltage capacitors are filled with oil, and the generous bushings required for clearance and creepage as well as internal safety mechanisms add substantially to the self-inductance of the capacitor. Based on decades of proprietary experience in metallizing capacitor films, ELECTRONICON has created a range of high voltage capacitors in self-healing technology, using the opportunities of special metallizing patterns. Despite the high voltage rating, our E51 range is manufactured in dry technology and without expensive bushings. Inside the can made of self-extinguishing plastic, the capacitor element is enclosed in solid resin (PUR). Connection is made through robust flat terminals with internal thread.

Any device is only as reliable as the sum of its components. With more than fifteen years of experience in manufacturing tuned and detuned filter reactors for power factor correction, we are now offering our range of line reactors for application in power electronics. Same as with our capacitors, we focus on minimized power losses and maximum durability of the reactor – optimized for your application. Made of high-class transformer sheets and copper wire or aluminium band. Vacuum-impregnated with environmentally friendly, low-styrole resin for long operating life, high voltage strength and low noise levels. Standard terminals: copper terminal lugs, optional with screw-terminal blocks or cables. Integrated reversible thermal switch for monitoring of the reactor and control of external disconnection in case of overheating. Our standard range covers 400V 50Hz up to 300A per phase. Other values are available on request.

The E62-3ph capacitors stand out by their high AC-voltage load capacity. They have been designed especially for heavy duty operation in extreme or sophisticated operating conditions, such as AC filtering and power factor correction in wind power and UPS applications, harmonic filtering in three-phase mains with high or unusual levels of harmonic distortion, a.m.o. Thanks to their construction, they have a very low series resistance and a small self-inductance. Our basic design principle - preferring short winding elements with comparably large diameters - as well as the use of wavecut technology in many models, serves for high rms and surge current strength. The three capacitor elements are connected in delta internally; the plant oil filling is environmentally friendly and serves for optimized heat dissipation and improved internal insulation.
