Solucio SF₆-Free ta Ring Main Units na Air-Insulated/Eco-friendly Gas

Ⅰ. Doka na Faduwar Tsarin SF₆​

1. ​Gabatar da Jirgin Ingantaccen​
   o Kyaukan Jirgin Zafiya/N₂ yana daya daga 1/3 na kyauka jirgin SF₆, wanda ya ba da zama da kawo gabatar da tsari daga 60mm zuwa ≥150mm.
   o Masana tsohon rukunin sauka babu kyauka don kawo masu gabatar da tsari mai yawa, wanda ya ba da zama da kawo gabatar da tsari mai yawa saboda tsari mai karfi.
   o Gas-gas na gaji (misali, C4+CO₂) suna cikin tsari suka faɗi, wanda ya ba da zama da ingantaccen jirgin gas da ba za a iya sake haɗa ba.
2. ​Ingantaccen Tsohon Gida​
   o Tsarin National Grid ta haɗa shirin gida a 420mm, wanda ya ba da zama da kawo gabatar da tsari mai yawa.
   o Gabatar da tsari mai yawa suna buƙata da kaɗan tsari na masu gabatar da tsari mai yawa a faduwar disconnector da tsohon gabatar, wanda ya ba da zama da kawo gabatar da tsari mai yawa a tsarin jirgin gas.

​II. Ƙwarewa da Sabon Fannin​
​​(I) Tsarin Yadda Da Jirgin Ingantaccen​

Bayanin Ƙwarewa: Yana daya da kawo gabatar da tsari mai yawa a gabatar da tsari mai 150mm, wanda ya haɗa shirin ingantaccen jirgin gas.

​​(II) Tsarin Yadda Da Disconnector da Tsohon Gabatar​

• ​Tsarin Yadda Da Inertia Mai Tsawo​
  Nylon main shaft mai yawa → Yana daya da kawo gabatar da tsari mai yawa → Kasa mai yawa >4m/s (yana daya da kawo gabatar da tsari mai yawa a 20kA short-circuit making kuma yana daya da kawo gabatar da tsari mai yawa <1ms).
• ​Tsarin Masu Gabatar da Tsari:​​ Masu gabatar da tsari mai yawa suna daya da kawo gabatar da tsari mai yawa ≥180mm a gabatar da tsari mai yawa.
• ​Akwai Jirgin Ingantaccen:​​ Disconnector da tsohon gabatar ta haɗa shirin E2-class contacts (yana daya da kawo gabatar da tsari mai yawa a 5 short-circuit making operations).

​III. Gabatar da Dalilai na Fannin​

​IV. Amfani da Tsarin Yadda Da Ingantaccen​

1. ​Tsarin Yadda Da Jirgin Ingantaccen​
   o Phase 1: 3D electric field simulation (gap field strength <3kV/mm)
   o Phase 2: Full/cutoff lightning impulse tests (±200kV)
   o Phase 3: Repeated insulation tests post E2-class short-circuit making
2. ​Tsarin Yadda Da Ingantaccen​
   o Hexagonal nylon shaft: Deformation-resistant lifespan >10,000 ops
   o Three-position mechanical interlock: Mandatory anti-misoperation locking
   o Making characteristic monitoring: Displacement sensors provide real-time closing speed curves

​V. Bayanin Ƙwarewa da Sabon Fannin​

• ​Ingantaccen Mai Tsawo:​​ Amfani da kawo gabatar da tsari mai yawa a gabatar da tsari mai yawa; ingantaccen jirgin gas yana daya da kawo gabatar da tsari mai yawa
• ​Amfani da Kowane:​​ Shirin da gida/interfaces ta haɗa shirin National Grid 420mm standard
• ​Tsarin Yadda Da Ingantaccen:​​ Vacuum interrupter lifespan >20 years; ba da gas replenishment needed
• ​100% Eco-Friendly Path:​​ Dried air enables carbon neutrality; zero F-gas management cost
