3. تحليل الغاز المذاب (دي جي ايه) Online Monitoring منتجات
DGA online monitoring systems represent the gold standard for detecting incipient faults in oil-filled transformers. By continuously analyzing dissolved gases in transformer oil, these systems identify developing electrical and thermal faults months or years before conventional testing would detect problems.
Online Oil Chromatograph Working Principles
حديث online DGA monitors employ various technologies including photoacoustic spectroscopy, كروماتوغرافيا الغاز, and electrochemical sensors. High-performance systems use micro gas chromatography with carrier gas circulation, achieving detection limits below 1 ppm for key fault gases. Automated sampling systems extract oil from the transformer, فصل الغازات الذائبة من خلال تقنية الأغشية, and inject samples into analytical chambers every 30-60 دقائق.

المتخصصة أنظمة المراقبة designed for offshore platforms and marine applications feature corrosion-resistant enclosures, enhanced environmental sealing, and saltwater-resistant components. These systems withstand salt spray, رطوبة عالية, and temperature extremes common in marine environments. Certifications for hazardous area installations (اتيكس, IECEx) enable deployment on offshore oil and gas platforms. Proven installations on offshore wind farms and production platforms demonstrate reliable long-term operation.
What training is required for monitoring system operation?
أساسي monitoring system operation requires minimal training, عادة 4-8 hours covering software navigation, alarm interpretation, and routine maintenance procedures. Advanced training for engineering staff includes diagnostic interpretation, data analysis techniques, and system configuration occupying 2-3 أيام. Most manufacturers provide comprehensive training materials including video tutorials, أدلة المستخدم, and application notes. On-site training and remote webinars accommodate different learning preferences and schedules.
