Dunia na ɗauke ɗaya da aka faɗa a kan 800 kV / 80 kA ya shafi gwargwadon ilimi na kasar.

A ranar 9 ga watan Yuli, wani abu mai suna mai yin gaba da zama shi ne don kumbancin gas-insulated metal-enclosed switchgear—da shi ya fi sani ZF27-800(L)/Y6300-80—ya zama da nasara a fice na cikin tashar tasirin fanni mai uku a Beijing da ke yi a kan CSEE (Chinese Society for Electrical Engineering). Wannan abu mai suna mai yin gaba ta da kayayyakin hakkin mallaka masu sauri da kuma makarantun fanni daban-daban suka yi aiki. Wannan abu mai suna mai yin gaba ta da kayayyakin hakkin mallaka masu sauri, da shi ya fi sani 800 kV, 80 kA, ya samu nasarorin alamar jami'a a kan duk fannonin muhimmanci. Matarin ta hankali ya ba shi nasarorin alamar jami'a, wanda ya nuna matsayin wani abubuwa mai muhimmanci a kan China a fanni na ultra-high-voltage (UHV) switching equipment, kuma ya nuna cewa an yi karfin da ake bukata a kan fanni.

Wannan abu mai suna mai yin gaba ta da kayayyakin hakkin mallaka masu sauri an yi a State Grid Shaanxi Electric Power Company, a cikin aiki da mutanen mallaka masu sauri, Xi’an Jiaotong University, da kuma China Electric Power Research Institute—wanda ya nuna matsayin misalai na aiki a kan tushen ilimi, fanni, da kuma aiki a kan yan amfani. Tashar ta hankalin R&D ya fara aiki da aikin rubutu na tsari da aikin tsari na arc dynamics a cikin high-voltage circuit breakers, kuma ya fara aikin rubutu na tsari don aikin tsari na interruption performance, wanda ya ci gaba a kawo nasarar da ake bukata a kan aikin tsari na 800 kV / 80 kA current interruption.

Wannan nasarori ya ba amsa mai inganci, mai kyau, da kuma mai amana a kan aikin tsari na short-circuit currents da ya zama da shi a kan grid na 750 kV a China, kuma ya zama da shi nasarorin alamar jami'a a kan amincewar, kyau, da kuma kyakkyawan aiki a kan yan aiki masu kwayoyin kasa. Wannan ya zama da shi nasarorin alamar jami'a a kan aiki da renewable energy sources, kuma ya zama da shi nasarorin alamar jami'a a kan amfani da energy. Kuma ya bayyana amsa mai kyau don aiki a kan fanni na power equipment technology a kan China zuwa hanyar voltage levels masu uku da kuma interrupting capacities masu uku—wanda ya nuna matsayin rike mai muhimmanci a kan aiki a kan industry na domestic power equipment na China zuwa “peer competitor” da kuma “global leader,” wanda ya nuna matsayin alamar jami'a a kan fanni na UHV switching technology a duniya.

Yanzu, a lokacin da China ta ci gaba a kan aiki a kan building a modern socialist country, aiki na economy da society ya bukata aiki da amsa masu kyau da kuma amincewa. A cikin cin kawo karfi a kan grid, integration da renewable energy, da kuma construction da new-type power system, short-circuit currents a wasu substations suka ci 63 kA. Wannan risk na short-circuit overloads da kuma instability ya bukata aiki da amsa masu kyau da kuma high-end switching equipment da 80 kA interruption capability.

A cikin wannan, State Grid Shaanxi Electric Power da kuma Chinese switchgear manufacturer suka yi aiki da aikin rubutu na tsari, suka kula resources, da kuma suka fara aiki da joint task force don aiki da key technological research da kuma prototype development don 80 kA high-capacity switchgear—wanda ya ba amsa core technologies da kuma equipment masu muhimmanci don new power system.

A cikin tattaunawa, wannan ZF27-800(L)/Y6300-80 circuit breaker da aka fice ta da kayayyakin hakkin mallaka masu sauri ta da kayayyakin hakkin mallaka masu sauri ta da kayayyakin hakkin mallaka masu sauri ta da kayayyakin hakkin mallaka masu sauri ta da kayayyakin hakkin mallaka masu sauri:

• World-leading technical specifications and exceptional reliability:
  The product achieves the highest standard ratings—E2-M2-C2—with an electrical life of 20 operations, mechanical life of 10,000 operations, and a DC time constant of up to 120 ms.

• Mature, reliable structure with stable insulation and mechanical performance:
  Built upon the proven technical platform of existing 800 kV / 63 kA circuit breakers, it retains a dual-break puffer-type arc-quenching chamber and hydraulic operating mechanism. Enhanced contamination control and optimized transmission systems further improve insulation integrity and mechanical reliability.

• Full dimensional compatibility for seamless engineering deployment:
  The new breaker shares identical external dimensions and interface specifications with currently deployed 800 kV / 63 kA units, enabling direct in-situ capacity upgrades at substations without modifying civil structures or foundations—offering significant advantages including shorter outage durations, minimal operational disruption, and outstanding cost-effectiveness.

Matarin mai karatu daga Chinese gas-insulated switchgear manufacturer ya ce cewa aikin tushen company za a yi aikin tushen innovation-driven development strategy, wanda za a yi aikin tushen innovation a cikin growth trajectory. A cikin strategic vision na “building a world-class smart electrical equipment group,” company za a yi aikin tushen R&D investment, a cikin political responsibility da kuma mission awareness, za a yi aikin tushen “bottleneck” core technologies. Wannan commitment ya nuna matsayin aikin tushen momentum masu kyau don aiki na high-quality development a kan China’s power equipment manufacturing sector da kuma ambition na country don become a global leader in advanced equipment manufacturing—writing a new chapter of scientific and technological self-reliance and strength on China’s journey toward national rejuvenation.
