مُعيد الإغلاق الفراغي ABB OEM للشبكات التوزيعية — نظرة عامة
مُعيد الإغلاق الفراغي ABB OEM هو معيد إغلاق ثلاثي الأطوار مثبت على الأعمدة لأتمتة شبكات التوزيع الهوائية متوسطة الجهد. يقلل مدة انقطاع الخدمة عن طريق عزل الأعطال الدائمة تلقائياً واستعادة الإمداد للأجزاء السليمة. يدعم بروتوكولات DNP3 وIEC 61850.
يُستخدم في برنامج تحديث شبكات التوزيع في شركة الكهرباء السعودية للوفاء بأهداف موثوقية الشبكة ضمن رؤية 2030. تنسق راز الشرق الأوسط التوريد والتركيب لمشاريع التوزيع عبر المملكة.

المميزات والفوائد
- Vacuum interrupter technology eliminates SF6 gas and oil media, requiring no periodic refill or dielectric maintenance — reducing SEC distribution maintenance team workload and avoiding SF6 greenhouse gas handling on thousands of distribution line reclosers.
- Adaptive protection with up to 4 configurable reclose cycles (instantaneous + time-delayed) differentiates transient faults from permanent faults, restoring supply automatically after temporary lightning or vegetation contact faults without dispatcher involvement.
- IEC 61850 GOOSE messaging and DNP3 Level 2 communication enables integration into feeder automation schemes where multiple reclosers coordinate to automatically restore the maximum portion of a faulted feeder within seconds of fault isolation.
- Directional overcurrent and earth fault protection allows correct operation on ring and meshed distribution networks where fault current can flow from either direction, enabling the more efficient ring-main network architectures required by NEOM and smart city projects.
- Under/over voltage and frequency protection functions provide load shedding and islanding detection capability, increasingly required as Saudi Arabia's distribution network accommodates distributed solar generation from commercial and residential installations.
- Integrated battery-backed control unit maintains protection and communication functions for up to 8 hours during supply interruption, ensuring the recloser continues to protect the line during the very distribution outage it is designed to manage.
- Remote firmware upgrade and parameter configuration via DNP3 or IEC 61850 communication reduces the need for physical site visits to change protection settings across geographically dispersed rural distribution feeders.
التطبيقات الصناعية
- SEC distribution feeder automation on 11 kV overhead lines across all five SEC regions, where OEM reclosers reduce SAIDI and SAIFI metrics to meet ECRA regulatory reliability benchmarks and Vision 2030 grid modernisation targets.
- Rural feeder sectionalising on high-fault-rate distribution lines in the Central, Western, and Southern regions of Saudi Arabia, where vegetation encroachment and lightning exposure cause frequent transient faults that automated reclosing can clear without extended supply interruption.
- NEOM's primary distribution loop network automation, where IEC 61850 GOOSE-communicating reclosers enable sub-second fault isolation and automatic supply restoration within the loop, maintaining near-continuous supply availability.
- Private industrial estate distribution network protection at MODON and industrial cities, where automated reclosing reduces dependence on manual fault location and restoration by maintenance teams working across large industrial site areas.
- Substation outgoing feeder protection replacing aging electromagnetic relay and oil circuit breaker combinations, where the OEM recloser's vacuum interruption and microprocessor control provides a direct modern replacement in existing pole-mounted positions.
- Renewable energy feeder protection on distribution lines connecting commercial solar farms to the SEC grid, where under/over voltage and frequency functions provide islanding detection required by SEC grid connection standards for distributed generation.
- Desert and remote location distribution protection where the vacuum interrupter's zero maintenance requirement and -30°C to +55°C operating range eliminate the periodic inspection and dielectric testing visits required for oil or SF6 reclosers.
