⚡ اختبار الحقن الابتدائي – Primary Injection Test

في الريل ده، مهندس MSR بيشرح عمليًا اختبار الحقن الابتدائي (Primary Injection Test) على قاطع جهد منخفض ABB ACB – 1250A، بدايةً من مكونات جهاز الاختبار وحتى تنفيذ الاختبار وقراءة النتائج.

🔧 إيه اللي هنشوفه في الريل؟
• شرح مكونات جهاز الـ Primary Injection Test Set
• توصيل كابلات التيار واختيار نقاط الاختبار
• ضبط قيمة تيار الاختبار وزمن الحقن
• تمرير تيار الاختبار خلال الـ Primary Circuit للقاطع
• اختبار استجابة وحدة الحماية Trip Unit
• التأكد من قيم الـ Pickup & Trip Time
• مقارنة النتائج بإعدادات الحماية المطلوبة
• توثيق نتائج الاختبار في تقرير الاختبار

🎯 ليه بنعمل Primary Injection Test؟
لأنه بيساعدنا نتأكد من عمل دائرة التيار والحماية كمنظومة واحدة، والتحقق من استجابة الـ ACB عند قيم التيار المحددة.

📍 Application:
ABB ACB – 1250A | LV Switchgear

Why Does Every Part of a Transformer Have a Specific Function? ⚡🔧

Have you ever wondered why a transformer has so many different components, and what each one actually does? 🤔

A Power Transformer is not just a core and windings. Every component has a specific function that works together to ensure safe, reliable, and efficient operation.

🔹 What are the main components and their functions?

Windings transfer electrical energy between the high-voltage and low-voltage sides.
Transformer Oil provides insulation and helps remove heat from the core and windings.
Radiators & Cooling Fans help dissipate the heat generated during operation.
Bushings provide safe electrical connection between the internal windings and external circuits.
Buchholz Relay helps detect internal faults and gas formation inside oil-filled transformers.
Conservator Tank allows the transformer oil to expand and contract with temperature changes.
Tap Changer adjusts the transformer voltage ratio to maintain the required output voltage.

🔧 Why is it important?
• Each component has a specific role in transformer operation.
• Proper maintenance of every part helps maintain transformer reliability.
• Early detection of component problems can help prevent unexpected failures.
• Regular inspection supports safe and efficient transformer operation.

⚠️ Understanding the function of each transformer component makes it easier to inspect, test, and maintain the transformer correctly.
