Solusyon para sa Proteksyon sa Matinding Kapaligiran at Mahabang Serbisyo ng Buhay na Mababang Voltaje na Current Transformers

​1. Pusod ng Problema: mga Hamon sa Masamang Kondisyon ng Paggamit​
Sa industriyal na awtomatikong pagproseso, outdoor power facilities, shipboard power systems, at espesyal na kondisyon ng operasyon, ang mga current transformers (CTs) ay patuloy na nakakaranas ng masamang mga elemento tulad ng mataas na temperatura, mataas na humidity, dust, salt spray, oil contamination, at vibration. Ito ay nagbibigay ng malubhang hamon sa kakayahan ng proteksyon ng mga kagamitan at matagal na reliabilidad. Ang mga tradisyonal na CTs ay madaling magkaroon ng insulation aging, component failure, accuracy degradation, at kahit safety incidents dahil sa pagkasira ng kapaligiran.

​2. Pangunahing Solusyon: Komprehensibong Proteksyon at Robustong disenyo​
​2.1 Fully Encapsulated Integrated Structure Design​

• ​Mga Materyales ng Casing:​​ Gumagamit ng high-strength engineering plastics (PPS o PBT) o die-cast aluminum housing na may surface anti-corrosion treatment (anodizing/epoxy coating).
• Engineering Plastics: Nagbibigay ng mataas na mechanical strength, chemical resistance (acid, alkali, oil), flame retardancy, at dimensional stability.
• Die-Cast Aluminum + Anti-Corrosion: Nagbibigay ng extraordinary na mechanical protection at heat dissipation capacity. Ang surface treatment ay mabisang nagsasanggalang laban sa salt spray at corrosion ng mainit at maalat na kapaligiran.
  ​2.2 High-Level Seal Protection sa Interfaces​
• ​Potting Process:​​ Ang wiring terminals at housing interfaces ay mahigpit na isinasara gamit ang IP67/IP68-rated waterproof sealant.
• Nag-uugnay ng zero ingress ng tubig, dust, o contaminants sa panahon ng continuous immersion, high-pressure water washing, o prolonged high-humidity environments, nagpaprotekta ng internal electrical connections.
  ​2.3 Enhanced Protection para sa Internal Electronic Components​
• ​Conformal Coating:​​ Inaapply ang high-reliability conformal coating sa internal PCBs at critical electronic components (e.g., signal conditioning circuits, ADC chips).
• Epektibong nagpapabuo ng protective film upang magsanggalang laban sa moisture, condensation, salt spray, mold, at harmful gas corrosion, nagpaprevent ng circuit corrosion at short circuits.
  ​2.4 Wide-Temperature Range, Long-Lifetime Component Selection​
• ​Component Grade:​​ Lahat ng core components (resistors, capacitors, ICs, magnetic materials) ay pinipili mula sa industrial-grade (-40°C ~ +85°C) o automotive-grade (AEC-Q certified) products.
• Nagbibigay ng stable performance sa extreme high/low temperatures at severe thermal shock. Ang failure rates ay significantly lower kaysa sa commercial-grade components, nagpapahaba ng overall lifespan.
  ​2.5 Vibration-Resistant Structural Optimization​
• Epektibong nagsasanggalang at nagdidisipa ng mechanical vibration at shock energy sa pamamagitan ng rational internal layout, anti-vibration damping design (e.g., flexible mounting, shock-absorbing washers), at housing rigidity. Nagpaprevent ng internal connection loosening o component damage, sumasang-ayon sa stringent vibration standards (e.g., IEC 60068-2-6).

​3. Core Advantages​

• ​Exceptional Environmental Endurance:​​ Nagsasagawa ng stable operation sa mga kapaligiran na may mataas na temperatura (hanggang 85°C), mataas na humidity (≥95% RH), dust, salt spray (sumasang-ayon sa IEC 60068-2-11), oil contamination, industriyal na chemical gases, at malakas na vibration.
• ​Ultra-High Protection Level:​​ Ang overall protection level ay umabot sa IP67 (dust-tight at protected against water immersion) o IP68 (continuous underwater protection), na lubos na lumampas sa mga requirement para sa conventional industrial equipment.
• ​Significantly Extended Service Life:​​ Sa pamamagitan ng anti-corrosion materials, sealing against moisture, long-lifetime component selection, at vibration-resistant design, ang Mean Time Between Failures (MTBF) ay lubos na nababago. Ang design life ay inaextend ng higit sa 50% kumpara sa standard products.
• ​Optimized Lifecycle Cost:​​ Nagbabawas ng failures, downtime, maintenance frequency, at replacement costs dahil sa environmental factors, na lubos na bumababa sa overall operation at maintenance expenses.

​4. Typical Application Scenarios​

• ​Heavy Industrial Environments:​​ Steel mills, chemical plants, cement plants, mining equipment (dust, high temperature, corrosive gases, vibration).
• ​Outdoor Power Facilities:​​ Wind/solar farm combiner boxes, outdoor distribution cabinets (sun/rain exposure, severe temperature fluctuations, condensation).
• ​Shipboard & Offshore Platforms:​​ Shipboard power distribution systems, offshore wind platforms (high humidity, salt spray, mold, vibration/shock).
• ​Rail Transportation:​​ Locomotive traction, onboard power distribution systems (strong vibration, wide temperature range, oil contamination).
• ​Special Equipment:​​ Construction machinery, agricultural machinery (oil contamination, mud, severe vibration).
