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.

அதன் செயல்பாடுகள் பின்வருமாறு:

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.

இயல்பான சேவை நிலை

The ambient air temperature shall not be higher than +40℃ and not lower than -5℃, and the average temperature within 24 hours shall not be higher than +35℃. When these limits are exceeded, the capacity shall be derated for operation according to the actual situation.

It is for indoor use, and the altitude of the installation locatin shall not exceed 2000m.

The relative humidity of the ambient air shall not exceed 50% when the maximum temperature is +40℃. At lower temperatures, a higher relative humidity is allowed. For example, it is 90% at +20°℃. The influence of occasional condensation caused by temperature changes should be taken into account.

When the device is installed, the inclination from the vertical plane shall not exceed 5°, and the entire group of cabinet rows shall be relatively flat.The device shall be installed in a place without severe vibration and impact, and where the electrical components will not be subject to undue corrosion.
