Specialized Voltage Transformer Solution for High-Speed Railway AT Power Supply System: Focused on Strong EMI Immunity

Electromagneticum ambientem systematis alimentationis AT (Auto-Transformer) ferroviarum altae velocitatis summe est complexus. Fortis interferentia electromagnetica (EMI) directe affectat accurate mensurandi transformatorum voltage et fidem systematis. Haec solutio specifica hanc corem procellam adsequitur per developmentum transformatoris voltage dedicati qui standardi 27.5kV unipolaris alimentationis satisfacit, fundamentum solidum praebens pro mensura energiae et protectione relais in ferroviis altae velocitatis.

Core Technological Breakthrough: Triple Defense Against EMI Storms

μ-Metal Alloy Triple Electromagnetic Shield:

Structure: Utilizes tres independentes interiores, medias, et externas tegumenta ab alto-permeabilitate μ-metal alloy constructa.
Efficacy: Effectively absorbet/bloccat fortis campum magneticum low-frequency generatum a 27.5kV lineae contactus superiore et EMI high-frequency transitoria causata a operationibus commutationis systematis. Elementum sensuum core effecte tectum est, puritatem signali assecurans.

27.5kV Dedicated Single-Phase Structural Design:

Precise Matching: Circuitus magneticus et windings profunditer optimizantur pro characteristicis 27.5kV power-frequency unipolaris, eliminantes effectus crosstalk phase-to-phase et augmentantes absolute accurate mensurationis puncti singuli.
Stability: Materiales speciales et processus significanter reducunt periculum saturationis core, garantientes velocitatem responsionis transitoriae et capacitate reproductionis waveform.

Vibration Resistance Enhancement (5-200Hz, 2g Acceleration):

Simulation-Driven: Utilizes FEA (Finite Element Analysis) simulare spectras vibrationum complexas in locis trackside (including characteristica vibrationes inducatas a CRH transitibus).
Reinforcement Solution: Componentes interni core sunt securati utendo potting elastico silicium. Housing externum utitur alligio high-strength et elementis anti-vibration, assecurans nullam connectionem solvendi/displacementem sub impactu mechanic longo pro accurate consistenti.

CRH Standard Communication Interfaces (RJ45 + TNC):

Dual Assurance: Interface RJ45 praebet communicationem digital standard basata in matura physica stratum Ethernet. Interface TNC redundanter designata (coaxial connector) assecurat transmissionem fidelissimam signorum analog/digital sub extremis interferentiis.
Immunity Capability: Circuitus interfaces habent multilayer EMC protection (TVS, filtering). Portae complentur cum rigorosis IEC 61000-4 series standards pro surge et EFT immunity.
