XL-21

The power cabinet refers to a combination of electrical control cabinets that provide power for the normal operation of the entire machine, including contactors, frequency converters,high-voltage cabinets, transformers, and so on.

Sus funciones son las siguientes:

Supply power to electrical equipment (provide power for the equipment);

Start and stop the operation of electrical equipment (with start and stop buttons);

Detect the operation of the equipment (set signal indicator lights, with ammeters and voltmeters);

Protect electrical equipment (circuit breakers).The power cabinet is the power distribution cabinet,which is specifically used to provide power supply and control for power equipment (generally referring to motors).

The XL-21 series low-voltage power distribution cabinets are widely suitable for industrial and civil buildings, and are used for power distribution and lighting distribution in a three-phase four-wire power system with an alternating current frequency of 50HZ,60HZ and a voltage of 1kV and below.

At the same time,it is suitable for manufacturing various motor staring cabinets, including full-voltage direct starting cabinets, fully digital control soft starting cabinets,autotransformer step-down starting cabinets,star-delta starting cabinets, multi-speed motor starting cabinets, etc.

There are dozens of primary circuit scheme numbers or derived scheme numbers for selection,with a wide range of applications.

This product is an indoor enclosed distribution box.

The box body is bent and welded with thin steel plates, and there is a single left-opening door on the front.Measuring instruments such as voltmeters and ammeters, as well as operating electrical appliances and signal electrical appliances, are installed on the door.

It is a power distribution device with a simple structure, reliable operation and low cost.

Descripción de tipo

Condición de servicio normal

La temperatura ambiente no debe ser superior a +40 °C ni inferior a -5 °C, y la temperatura media en 24 horas no debe superar los +35 °C. Si se superan estos límites, se reducirá la capacidad de funcionamiento según la situación real.

Es para uso en interiores y la altitud del lugar de instalación no debe superar los 2000 m.

La humedad relativa del aire ambiente no debe superar el 50 % cuando la temperatura máxima sea de +40 °C. A temperaturas inferiores, se permite una humedad relativa más alta. Por ejemplo, es del 90 % a +20 °C. Debe tenerse en cuenta la influencia de la condensación ocasional causada por los cambios de temperatura.

Al instalar el dispositivo, la inclinación respecto del plano vertical no debe superar los 5° y todo el grupo de filas del gabinete debe ser relativamente plano. El dispositivo se debe instalar en un lugar sin vibraciones ni impactos severos y donde los componentes eléctricos no estén sujetos a corrosión indebida.
