How does a Solid Insulated Switchgear work?

The functioning of a Solid Insulated Switchgear depends on working of its components.

عندما يحدث خطأ، يتأرجح التتابع إلى العمل عن طريق إغلاق رحلة الدائرة.

يتم ذلك من خلال الفصل التلقائي لخط الصدع.

بعد ذلك، تعمل الأقسام الصحية والعاملة على ضمان تدفق حمولة الإمداد الطبيعية المطلوبة.

ومن خلال ذلك، يتم توفير إمداد كهربائي سلس في جميع أنحاء المعدات، مما يضمن عدم حدوث أي ضرر.

يؤدي التحميل الزائد للخط إلى منع التيار من القيام بعملية إطلاق كهرومغناطيسية.

ومع ذلك، فإنه يبدأ إنتاج الحرارة عن طريق العنصر الحراري.

يقوم السخان بتسخين الصفيحة المعدنية الثنائية مما يؤدي إلى ثنيها إلى الأعلى.

يؤدي هذا إلى دفع الرافعة إلى الأعلى، مما يؤدي إلى قفل الخطاف.

يؤدي هذا إلى قطع الاتصال الأساسي، مما يؤدي إلى قطع مصدر الطاقة.

من خلال القيام بذلك، عندما يكون هناك حمل زائد، فإنه يتجاوز التيار المحدد مما يتسبب في قيام المرحلات الكهرومغناطيسية بإنتاج الشفط.

A combination of the suction and the impact lever results in the lap hook to rotate upwards around the shaft seat

ويؤدي هذا إلى تحرير القفل.

How do you Troubleshoot Solid Insulated Switchgear?

Solid insulation switchgear

The following are the main causes of Solid Insulated Switchgear failure and the ways of troubleshooting them:

· الضوضاء الداخلية

The cause of your switchgear producing internal noise is due to the electromagnetic induction screws that are on the partitioning plates.

تشكل لوحات الغدة التي تلامس الكابلات مصدرًا آخر للضوضاء الداخلية.

تأكد من أنك قمت بإحكام ربط البراغي الموجودة على ألواح التقسيم ووضع طبقة من المادة المانعة للتسرب على الكابل.

· التوصيلات المحمومة

هذا نتيجة لوجود مسامير علوية فضفاضة.

لحل هذه المشكلة، تأكد من استخدام قيمة التيار المقدرة.

بالإضافة إلى ذلك، قم بإحكام أي برغي فضفاض واستبدل قضيب التوصيل إذا لزم الأمر.

· The Switchgear Fails the Dielectric Test or Ground Fault

تتسبب العوازل المتشققة في حدوث ذلك، حيث تكون هذه العوازل عرضة للرطوبة أو الملوثات الغريبة.

ولحل هذه المشكلة، تحتاج إلى استبدال العوازل.

يمكنك أيضًا التنظيف باستخدام عامل تنظيف مناسب وتجفيف الأجزاء الرطبة.

· مصاريع لا تغلق

السبب الرئيسي لعدم إغلاق المصراع هو المصاريع التالفة.

ولحل هذه المشكلة، تحتاج إلى إصلاح المصاريع وتنظيف الأجزاء القابلة للتعديل.

يمكنك أيضًا وضع زيت التشحيم على هذه الأجزاء لتسهيل عملية الإغلاق.

· إشارة إلى انطفاء الضوء

Indicating light extinction may be as a result of the following: Fuse or resistor burnt, broken bulb filament, faulty limit switch contactor poor contact of the auxiliary switches.

لإصلاح ذلك، يجب عليك التحقق مما يلي: تغيير المصباح، أو استبدال المصهر أو المقاوم، أو تنظيف جهات الاتصال المساعدة، أو مراقبة MCCB لأطراف المصهر.

· You Cannot Lock the Handle

تنشأ هذه المشكلة بسبب صدأ آلية القفل الداخلية أو وجود خلل في آلية القفل.

من الممكن أيضًا أنك تستخدم المفتاح الخاطئ للفتح.

لحل هذه المشكلة، تأكد من استخدام المفتاح الصحيح.

يجب عليك تشحيم آلية القفل أو استبدالها بالكامل.

· ضعف تشغيل وحدة التحكم

قد يكون ضعف تشغيل وحدة التحكم بسبب البراغي غير المثبتة في الكتل الطرفية.

وبدلا من ذلك، قد يكون السبب هو اتصال غير صحيح لمقبس التحكم.

يجب عليك تشديد مسامير الكتل الطرفية.

يمكنك أيضًا توصيل مقابس التحكم بشكل مناسب.

· المصاريع لا تفتح

إذا لم تفتح مصاريعك، فقد يكون ذلك بسبب سوء ضبط الأجزاء المتحركة أو نقص التشحيم في هذه الأجزاء.

كما يمكن أن يكون ذلك بسبب مصاريع مشوهة.

ولحل هذه المشكلة، تحتاج إلى ضبط وتزييت الأجزاء المتحركة والتحقق من المصاريع للتأكد من شكلها غير الصحيح.
