Circuitus et Commutator Terrae Magnetici Reuti Integrati Soluto: Faciens Constructionem Compactam Substationis GIS
Background
In urbe rete electricum renovando, limitata terra resursum praebet nucleum difficultatis. Traditio GIS instrumenta multam spatium verticalis occupant propter structuras separatas currentis transformatorum (CT) et terrae commutatorum, quod fit collum in stationibus minoribus designandis.
Solutio: Modularis Integratum Design
Hoc solutio innovanter profunditer integrat CT functionem in terrae commutatoris operativi mechanismum, ad spatiolum reusum et performance breakthroughs:
- Efficax Spatii Reusum:
- Inclusus CT Coil: Removet traditionalem independentem CT insulator, inclusis altae precisionis mensura coil directe intra cavum structura terrae commutatoris insulati operativi virgae.
- Magnetic Circuit Closure GIS Enclosure: Utilizatio breakthrough GIS instrumentorum fortis metal enclosure ut core parva resistencia via pro CT magnetic flux, formans integrum clausum magnetic circuit. Occupatio spatii verticalis significanter minuitur.
- Precisa Magnetic Circuit Compensation:
- Dual-C Laminated Silicon Steel: Ad respondendum potentiali non-uniformitate distributionis magnetic field causata structura non-axial symmetria instrumentorum (estimata deviation linearitas ≤5%), core utitur dual-C typus 0.23mm alta permeabilitas silicon steel sheet laminated modules.
- Directed Magnetic Flux Guidance: Symmetric C-shaped structura design precise compensat pro magnetic circuit asymmetry, securans current measurement linearity deviation stabilis maneat ≤0.5% sub statu stabili et transient (usque 40kA peak), satisfaciens Class 0.2S accurate requirements.
- Contact Synchronization Monitoring:
- Dual Hall-Effect Sensor Synchronization: Alta sensitivitas Hall-effect sensor arrays sunt inclusi in key transmission nodos terrae laminae power linkage.
- State Synchronized Output: Collectio real-time status apertus/clusus mechanica positionis laminae, ad efficaciam tempus synchronization (timestamp alignment accuracy ≤1ms) cum phase current signal output ex CT.
Nucleus Scenario Valorem: Urbana Compacta GIS Stationes
- Compression Spatii Breakthrough: Profunditas verticalis structurae instrumentorum reducitur directe per 1.2 metra, impellens optimisationem generalis stationis layout. Medius stationis vestigium successime reducitur per 30% (exempli gratia, 220kV GIS distributio area).
- Lifespan Consistency Design: Structura integrata simplificat catenam transmissionis. CT et terrae commutator partibus core motilibus (exempli gratia, operativi virgae bearing system). Validatus super 10,000 full-capacity apertus/clusus operation cycles, assequens synchronizata mechanic life targets.
- Intelligent O&M Enablement: Altissima fidelitas millisecond-level synchronization Hall position signals et CT data praebet unprecedented device-level data support ad analysandum terrae commutator operation transient currents et arc reignition risks.
