75 kVA ~ 2500 kVA UL-Listatus Explosio-Proof Standard Pad-Mounted Transformer

Descriptio:

Transformator Pad-Mounted Explosion-Proof Standard UL-Listatus est transformator oleo-immersus pad-mounted certificatus a Underwriters Laboratories (UL), specialiter designatus pro ambientes periculosos. Suas certificationes et standardes core sunt:

• Certificatio UL: Compatit cum UL 506 (Standard Transformatoris) et UL 1203 (Standard Equipmenti Explosion-Proof), assecurans operationem tuto in ambientes periculosos.
• Rating Explosion-Proof: Usualiter notatus ut Class I, Division 1 (pro ambientes flammabilis gas) vel Class II, Division 1 (pro ambientes pulvis combustibilis), adhærens ad National Electrical Code (NEC 500/505).
• Standardes Structural: Basati super IEEE C57.12.20 (American Pad-Mounted Transformer Standard) et NEMA 3R/4X (Enclosure Rating Standards).

Core Design Features:

• Enclosure Explosion-Proof: Constructum ex aluminio fundito vel aço inox, superficies iuncturales et hiatus strictim compatunt cum UL 1203 (e.g., hiatus ≤0.15mm) ad prohibendum propagationem flammae durante arcing internum.
• Systema Relief Pressure: Equipatum cum valvulis dualibus redundantibus relief pressure (pressura operativa 55±5kPa) et spark arrestors ad prohibendum rupturn vasorum et explosiones secundarias.
• Insulation Oleo-Immersus: Utilizat oleum insulationis alti flash-point (e.g., oleum silicium cum flash point >300°C) vel β-fluid (compatens cum UL 3406) ad reducendum pericula incendii.
• Rating Sealing: Habet constructionem full-welded cum vasculis corrugatis, transiens tests explosionis UL 50E (test explosionis mixture metano-aer) ad prohibendum ingressum substantiarum combustibilium.
• Connectiones Electricales: Equipatum cum glandis cable explosion-proof (certificata UL 1203) et juncturas Ex d-type flameproof ad assecurandum quod scintillæ ad terminales non ignitent gases ambientales.

Functions et Core Applications:

• Supply Power Tuta: Facit conversionem energiæ electricæ in ambientes flammabilis dum prohibet scintillas vel altas temperaturas ab triggerando explosions.
• Isolation Fault: Continet faultus internos (e.g., arcing, decompositio olei) intra enclosure per design explosion-proof.
• Adaptation Environmental: Cum rating protectionis IP66, resistit ingressu gas corrosivorum et pulveris.
