Dünyanın İlk 500kV/90kA Kost-Effective AC Current Limiter: R&D Başarı ve Grid Denemesi

Diha, yekêmîn karanîna bingehên jorî AC 500kV/90kA wekî pirûrên werzerdar yên di çarçoveyê de hat dabeşkirin, ku ji aliyê Guangzhou Power Supply Bureau yên Guangdong Power Grid û China High-Voltage AC Current Limiter Manufacturer re hat çêkirin, beşikariya xebitina qusaya serbest hat bêtirandin û bi serastî li rêzik 500kV Guangnan Substation-ê yên Shunguang Jia Line-ê hat pêvekirin. Wek projeyê nîşanî yên Programê ya R&D Yekemî yên Wirîna Çinar, bêtirandina projeyê “Development of 500kV and Above Cost-Effective High-Voltage AC Current Limiters” piştguhên teknolojî yên taybetmend ên digerandin da ku hewceyên ultra-bingeha qusaya jorî AC bikin. Pirûrên ekonomîk û yekparast yên guherandina hewceyên jorî AC bingeha wekî destpêk û pêşdestpêkirinê yên berdestpelan operasyonê yên rêzikên bingeha welatger hat da.

China High-Voltage AC Current Limiter Manufacturer şeftiya bêtirandina projeyê hat kirin, ku wek projeyê radyo A yên nîşanî yên Group-ê hat neqdar kirin. Şirket bi tarzê îlimdar hat resursên hate sertkirin, ku bizînin business division-ê hat girîngkirin. Di navbera navend, resursên zevanyên hat parastin, R&D yekbûy hat kirin û tekmîlên teknolojî yên yekbûy hat kirin. Pas sê salê geleyê, komîta hat hemî wazên bêtirandina projeyê hat kirin.

Terindarî yên Terindarî – Destpêka “Multi-Point”
Di dizaynê struktûrî yên pirûrde, şema switchê fast tank hat bijirin, ku terindare yên powering secondary components yên fast switch li ser platforma insulation bingeha û terindare yên maintenance li ser cihên hêla bingeha hat çareseribin. Projeya terindare yên teknolojî yên hêzane, ku hewceyên insulating pull rods yên girtîn, mekanizmaên repulsion-driven yên girtîn, bellows yên high-voltage-differential û high-speed vacuum interrupters, biguherînên interruption characteristics yên vacuum interrupters li ser şertên high-speed, arc-quenching characteristics yên vacuum interrupters yên high-capacity û high DC components, û mechanical structural strength design yên components li ser electromagnetic repulsion forces. Li ser anîva control secondary, komîta terindare yên key yên development of high-voltage thyristor drive modules, design of the current-limiting controller system, rapid fault detection û identification, û ensuring reliable operation of secondary control systems li ser electromagnetic environments yên intense hat çareseribin.

Parastina Yekbûy – Promoting Integration of “Primary and Secondary” Systems
Teknolojî yên pirûrda li ser interdisipliner integration yên reactor, switchgear, vacuum interruption, power electronics, û microelectronics hat dibên. An include system analysis û calculation, system integration, primary electrical equipment technology, intelligent technologies for fault detection/identification û control/protection—representing strategic direction yên new technology development yên Group-ê. Integration of primary û secondary systems also supports expansion of related diversified businesses. Throughout the project, enterprises within the Group fully leveraged their collaborative advantages, with seamless cooperation across companies, departments, û personnel to ensure timely û successful project completion.

Efficient Organization – Implementing “Project-Based” Management
The project adopted the IPD (Integrated Product Development) R&D model. Coordinated by China’s Ministry of Industry and Information Technology (MIIT), Guangdong Power Grid Company, China High-Voltage AC Current Limiter Manufacturer, û its affiliated enterprises, the management structure featured layered oversight, a dedicated project supervision team, û specialized task forces with clear objectives û assigned responsibilities. The effectiveness û planning discipline of project management were especially evident during manufacturing. Thanks to comprehensive efforts in early-stage innovative R&D, collaborative development, û system-level R&D, the engineering design, reliability validation of manufacturing processes, production û inspection of first-batch components, installation/maintenance procedures, û full-system commissioning of the pilot demonstration unit were all completed in less than four months—demonstrating remarkable “Chinese speed.”

The successful completion of this project is a concrete action by China High-Voltage AC Current Limiter Manufacturer to implement the national directive to “accelerate the establishment of original technology sources û become a modern industrial chain leader.” It also represents another practical step in executing the Group’s “core business focus with related diversification” development strategy. This achievement not only reflects the Group’s ongoing commitment to leading industry advancement but also showcases the Chinese spirit of perseverance, responsibility, pragmatism, û bold innovation in the face of challenges.
