REDUCIR LOS FALLOS Y AHORRAR COSTES CON REACTANCIAS DE RED

Una reactancia de red descarga la red de alimentación compensando la potencia reactiva de armónicos. Las ondas armónicas se reducen en gran medida.

El pico de corriente, sumamente elevado debido al principio de funcionamiento de la rectificación, es atenuado por la inductancia en más de un 60%.

¿Por qué es conveniente montar una reactancia de red de forma adicional?

- Atenuación del elevado pico de corriente hasta un 40%

- Reducción al mínimo de la deformación de la tensión de red sinusoidal

- Descarga del sistema de alimentación a través de la compensación de la potencia reactiva

- Limitación de las perturbaciones de red como, por ejemplo, caídas y picos de tensión

  • NTT MD 953

    Liquid-cooled three-phase mains choke 8% Uk

    NTT MD 953
    • Tensión nominal: 400 V
    • Corriente nominal: 200 - 1200 A
    • Inductancia: 0,012 - 0,074 mH

    Watercooled chokes are available are available with ingress protection ratings IP00 to IP65. REO can utilise several methods of water cooling these components. This provides controlled conduction of heat losses, ensuring that the local environment is not heated. Water cooling ensures that component temperatures are greatly reduced, reducing component stress and increasing product life. REO technology provides excellent heat distribution, preventing the emergence of so-called hot spots.
