Solusyon para sa Proteksyon sa Masamang Kapaligiran ug Matagal nga Serbisyo Low-Voltage Current Transformers

​1. Pokus: mga Hamon sa Masamang Kalagayan ng Operasyon​
Sa industriyal na awtomatik, outdoor na pasilidad sa kuryente, sistema ng kuryente sa barko, at espesyal na kalagayang operasyonal, ang mga current transformers (CTs) ay laging nakakasalubong ng masamang kondisyon 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 aparato at matagal na reliabilidad. Ang mga tradisyunal na CTs ay madaling mabawasan ang insulation, pagkakasira ng mga komponente, pagbaba ng katumpakan, at kahit na insidente ng seguridad dahil sa pagkasira ng kapaligiran.

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

• ​Mga Materyales sa Casing:​​ Ginagamit ang 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 espesyal na mechanical protection at heat dissipation capacity. Ang surface treatment ay mabisa na nasisira ang salt spray at corrosion sa maalat at maputlaang kapaligkan.
  ​2.2 High-Level Seal Protection sa Interfaces​
• ​Potting Process:​​ Ang wiring terminals at housing interfaces ay mahigpit na piniprotektahan gamit ang IP67/IP68-rated waterproof sealant.
• Nag-aalamin na walang pumasok na tubig, dust, o contaminants sa panahon ng patuloy na immersion, high-pressure water washing, o mahabang panahon sa mataas na humidity, protektado ang internal electrical connections.
  ​2.3 Pinataas na Proteksyon para sa Internal Electronic Components​
• ​Conformal Coating:​​ Ang high-reliability conformal coating ay inaaplay sa internal PCBs at critical electronic components (e.g., signal conditioning circuits, ADC chips).
• Mabisa na nabubuo ang protective film upang labanan ang moisture, condensation, salt spray, mold, at harmful gas corrosion, at 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 napili mula sa industrial-grade (-40°C ~ +85°C) o automotive-grade (AEC-Q certified) products.
• Nagbibigay ng stable performance sa ekstremong mataas at mababang temperatura at severe thermal shock. Ang failure rates ay mas mababa kaysa sa commercial-grade components, nagpapahaba ng overall lifespan.
  ​2.5 Vibration-Resistant Structural Optimization​
• Mabisa na inaabos at dinidisipa ang mechanical vibration at shock energy sa pamamagitan ng makatwirang internal layout, anti-vibration damping design (e.g., flexible mounting, shock-absorbing washers), at housing rigidity. Nagpiprevent ng internal connection loosening o component damage, sumasapat sa mahigpit na vibration standards (e.g., IEC 60068-2-6).

​3. Pangunahing 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, industrial chemical gases, at strong 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 napapahaba ng higit sa 50% kumpara sa standard products.
• ​Optimized Lifecycle Cost:​​ Nagbabawas ng failures, downtime, maintenance frequency, at replacement costs dahil sa environmental factors, lubos na binababa ang 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).
