AIS CT Cost Optimization Design Scheme: A Cost-Effective Solution for Small and Medium-Sized Substations Dokumenta na IEE-Business: Paddede na Tushen Yawan Gabatarwa na AIS CT: Zan Iya Kula da Adadin Rijin Gaba-gabanar da Karkashin Mafi Kadan da Karkashin Mafi Yawan Gabatarwa

Na farko masu karkashin gurbin kungiyoyi na kungiyoyin kadan da mara, musamman a cikin yadda aka fi sani game da gudummawa a cikin karkashin kungiyoyin kadan da mara da kuma karkashin kungiyoyin photovoltaic ta zama, ita ce mafi muhimmanci a kontrola tushen samun abubuwa. A Current Transformer (CT), wanda yake shahara a matsayin abubuwan bincike da ingantaccen amfani a cikin Air Insulated Switchgear (AIS), yana ba da fa'idar ekonomi mai yawa tun daga tushen al'adu. Wannan halaye yana samun takaice mafi yawa a tushen gudummawa na CT tare da hakan ya sahihi masu ayyukan karkashin (Class 0.5 accuracy, Protection (P) class).

Takaitaccen Tushen Al'adu

Kawo Kudin Samun Abubuwan: Teknologi na Laminated Stepped Core

Innovation: Ya kawo kudin karfin abubuwan da ke rasa a tsarin al'adu da take da al'umma a kan core da ke rasa a tsarin al'adu. An yi amfani da silicon steel sheet DQ151-30 (kudin tushen, haske masu fuskantar) a tsakiyar core, inda ingantacce masu magana shine mafi yawa da kuma ingantacce masu bincike shine mafi muhimmanci. Silicon steel sheet DR510-50 na kudin tushen an yi amfani a wuraren peripheral inda ingantacce masu magana shine mafi yawa.
Benefit: Yana kawo kudin amfani da abubuwan. Yana ci gaba da ingantacce masu bincike a tsakiyar core da ke rasa a tsarin al'adu tare da kawo kudin tushen a wuraren peripheral. Yana samun takaice mafi yawa ga 22% a tushen samun abubuwan, tare da adadin kawo kudin tushen shine mafi yawa da kuma Class 0.5. Wannan babban tushen yana kawo kudin tushen da kuma ci gaba da ingantacce masu bincike.

Innovation na Topology: Single-Core Multi-Tap CT

Innovation: Ya kawo kudin karfin al'adu da ke rasa a tsarin al'adu da take da al'umma a kan core da ke rasa a tsarin al'adu. An yi amfani da "single-core multi-tap" design. Tun daga precision magnetic circuit partitioning a kan core, an yi amfani da winding functions da suka bi (e.g., 0.2S class (high-precision measurement) / 0.5S class (metering) / 5P20 class (protection)).
Benefit: Wannan tsari yana kawo kudin adadin cores da ke rasa a tsarin al'adu. Testing ya tabbatar da kawo kudin 40% a total core volume. Wannan yana kawo kudin tushen samun abubuwan tare da kuma kawo kudin adadin abubuwan, wanda yake da kyau a cikin kungiyoyin kadan da mara.

Proses na Gudummawa na Automation: Robotic Precision Winding

Innovation: An yi amfani da high-precision six-axis industrial robots a kan critical coil winding stage.
Benefit: Robot winding positional accuracy an kontrola a tolerance of ±0.05mm. Ingantacce masu gaskiya da kalmomin yana kawo kudin tushen samun abubuwan, tare da kawo kudin tushen samun abubuwan da kuma kawo kudin tushen samun abubuwan, wanda yake da kyau a cikin mass production.

Comprehensive Benefits and Application Scenarios

Significant Cost-Effectiveness: Through the synergistic effect of material, structural, and process innovations, this solution achieves an overall manufacturing cost reduction of 35% for AIS CTs compared to traditional schemes. This substantial reduction provides strong support for optimizing the project's total equipment cost (Balance of Plant - BOP).
Performance Guaranteed: All optimizations are rigorously implemented while strictly guaranteeing core performance indicators (Class 0.5 accuracy, P-class protection characteristics), complying with relevant IEC/GB standards.
Core Application Scenarios:

Rural Grid Upgrade Projects: Highly cost-sensitive, where this solution can effectively reduce investment in distribution automation construction.
Distributed Photovoltaic (PV) Step-Up Stations: Small and medium-capacity PV projects are typically small-scale with long payback periods, creating an urgent demand for cost-effective equipment.
Compact User Substations / Prefabricated Substations: Require high standards for both equipment footprint and cost.
Other Small/Medium-Sized AIS Substations with Strict Cost Control Requirements.
