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.

यसको कार्यहरु निम्नानुसार छन्:

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.

परिवेशको हावाको तापक्रम +४० डिग्री सेल्सियसभन्दा बढी र -५ डिग्री सेल्सियसभन्दा कम हुनुहुँदैन, र २४ घण्टा भित्रको औसत तापक्रम +३५ डिग्री सेल्सियसभन्दा बढी हुनुहुँदैन। जब यी सीमाहरू नाघेका हुन्छन्, वास्तविक अवस्था अनुसार सञ्चालनको लागि क्षमता घटाइनेछ।

यो भित्री प्रयोगको लागि हो, र स्थापना स्थानको उचाइ २००० मिटर भन्दा बढी हुनुहुँदैन।

अधिकतम तापक्रम +४० डिग्री सेल्सियस हुँदा परिवेशको हावाको सापेक्षिक आर्द्रता ५०% भन्दा बढी हुनुहुँदैन। कम तापक्रममा, उच्च सापेक्षिक आर्द्रतालाई अनुमति दिइन्छ। उदाहरणका लागि, +२० डिग्री सेल्सियसमा यो ९०% हुन्छ। तापक्रम परिवर्तनका कारण कहिलेकाहीं हुने संक्षेपणको प्रभावलाई ध्यानमा राख्नुपर्छ।

उपकरण स्थापना गर्दा, ठाडो समतलबाट झुकाव ५° भन्दा बढी हुनुहुँदैन, र क्याबिनेट पङ्क्तिहरूको सम्पूर्ण समूह तुलनात्मक रूपमा समतल हुनुपर्छ। उपकरण गम्भीर कम्पन र प्रभाव बिनाको ठाउँमा स्थापना गर्नुपर्छ, र जहाँ विद्युतीय घटकहरू अनावश्यक क्षरणको अधीनमा हुनेछैनन्।
