Smarte IoT-Enabled Air-Insulated Switchgear Voltage Transformer (AIS-VT) Réiteach
I. Príomhachmhainní i Nuashonrú Intileachta an Gride
Trádúil Transformers Voltáis (VTs), mar tháirge cruinn chun monitóireacht a dhéanamh ar an grid, agus iad ag éirí ina bhealach cosúil le bolg sa dhaonraú digiteach:
- Lack of Dynamic Monitoring: Teoranta go mionsuimheanna voltáis bunúsacha; gan an tseargearradh milliseacunda a bheith in ann (mar shampla, lagúcháin voltáis, disortúcháin harmonach).
- Untapped Data Value: Tuarascáil rachmhaighnéadach atá ag teastáil ó thrasnáil agus córais athrú, ag cruthú moill ard agus fuathúlacht, ag coinneáil cinntí ginearálta réidh.
- Protocol Incompatibility: Seoide traidisiúnta nach féidir leis siad a dhéanamh amach saincheana digiteacha, ag briseadh comhtháthú shonraithe san stáisiún uathshonraithe.
Tá gá thodhchaí le reathaíocht a dhéanamh ar monitóireacht voltáis trí intileacht inbhuite agus IoT a chur chuile cheann de chéile.

V. Value Proposition
Reconstructs the system through a "Sensing-Computing-Protocol" trinity:
- Device Layer: AI chips inbuilt transform voltage measurement from signal transmission to event analysis.
- Network Layer: 9-2LE protocol enables digital circulation between devices.
- System Layer: Deep integration with SCADA generates actionable insights (e.g., voltage vulnerability maps).
Delivers 67% reduction in power quality incidents and second-level fault recovery for distribution networks.
