Modular da Space-Intensive Structure Solution: The Breakthrough Application of GIS Voltage Transformers in Compact Urban Substations
Abin da Ya Bace: Tsawonsu na Taurari na GIS Voltage Transformers na Tarihi
A cikin tashar masana, mazaunin kusa, ko tattalin jirgin kuliya na tsafta, kayan aiki na mazaunin tsafta yana daga cikin abubuwa. Wannan na GIS Voltage Transformers (VTs) na tarihi, saboda tsarin taurari, suna da fadada mai yawa (tsayi na aiki na 4 m² don sadarwa na 400kV), tufafin magunguna, da tushen gas compartment connection points. Wannan ya ba da takaicin lokacin da gaba-gaban da zai iya hagu, kuma ya ba da karfin samun muhimmanci na mazaunin tsafta na zamani, wanda ya zama matsalolin mutane da ke sa shugaban tsafta na birnin.
Babban Lafiya: Sandwich-Style Modular Integrated Design
- Tsarin Aiki na Kayan Aiki
- Innovation Mai Tsawo: Amfani da "VT-disconnect switch sandwich module," wanda ya haɗa electromagnetic voltage transformer (VT) da isolation/earthing switch zuwa daya daga gas compartment unit.
- Muhimmanci na Tsarin: Daɗe tushen flange connections daga tufafin magunguna na tarihi, ta ci gas compartment interfaces da sealing points da 50%, ta ƙara ƙwarewa da gas leakage risk da failure points.
- Misali na Parameter: Tsayi na 400kV GIS VT unit ta ci ≤ 1.8m, wiring complexity ta ci 60%.
- Tekologi na Shell na Kyauta
- Sakamako na Rukuni: Shell ya amfani da high-strength aluminum-magnesium alloy (tensile strength ≥350MPa), da ta baya steel casings, ta ci wall thickness da 25% ta hanyar insulation strength na ƙasa.
- Compression na Tsayi: Overall diameter ta ci 30% (misali, 400kV VT outer diameter ta ci Φ600mm). Equipment footprint area ≤2.5 m² (including operating mechanism), ta daidaita zuwa ultra-narrow 2.5m×2.5m shaft layouts.

Validation na Babban Lafiya
Wannan babban lafiya an yi amfani da shi a projects kamar underground 275kV substation a Shinjuku, Tokyo, da Shanghai Hongqiao Business District smart grid:
- Space Adaptability: An samu 6 groups of 400kV VTs a 18m-deep underground shaft, ta samu device density of 0.4 units/m² (traditional scheme ≤0.25 units/m²).
- Reliability Record: Zero seal failures over 12 months of continuous operation, partial discharge < 3pC (meeting IEC 62271-203 standard).
Kalmomin: The Inevitable Evolution of Compact Design
Tare da hanyar tekologi na Modular Integration (Integration) + Lightweight Materials (Lightweighting) + Structural Optimization (Compaction), wannan babban lafiya ta tabbatar da iyakokin tsayi na aikinsu na GIS voltage transformers. Duk da ma'anarsa a kan tsayi 35% na tsafta, ta ba da tashar hardware architecture foundation don tsafta na birnin na tsafta na tsafta na zamani.
