13. שאלות נפוצות

What is the essential difference between fluorescent fiber optic and traditional PT100 RTD?

Fluorescent fiber optic monitoring uses all-dielectric fiber transmission with sensor probes containing no metallic or electronic components, achieving complete electrical isolation with natural high voltage insulation (>100kV) and electromagnetic interference immunity. PT100 RTDs require metallic wire connections, creating safety hazards in transformer high voltage environments and extreme susceptibility to lightning strikes and switching transients causing false alarms. Fluorescent fiber optic technology delivers ±1°C accuracy with >25-year operational life, making it the optimal solution for transformer online monitoring.

How many temperature monitoring points does a transformer actually need?

Sensor quantities depend on transformer capacity, דרגת מתח, ביקורתיות, ומגבלות תקציב. שנאי הפצה (10kV/1600kVA) require minimum 6 points covering three-phase winding critical locations. שנאי כוח בינוני (110kV/50MVA) recommend 12-15 points including windings, ליבה, וריבוד נפט. Large substation transformers (220kV/180MVA+) suggest 18-24 points for comprehensive hot spot networks. Contact our engineers for application-specific recommendations.

How do oil-immersed transformer internal sensors achieve long-term sealed reliability?

Professional oil-immersed fiber optic temperature sensors employ multi-stage sealing: probe front-end uses oil-resistant rubber O-rings with metal compression nuts for primary sealing; fiber penetration points feature epoxy resin potting with heat-shrink tubing for secondary protection; sensor housings use 316 stainless steel resisting transformer oil corrosion. FJINNO oil-immersed sensors pass continuous 3000-hour high-temperature aging tests (130°C transformer oil immersion) ו 5000 thermal cycle shock tests ensuring 25-year service with zero leakage risk.

What special technical requirements apply to dry-type transformer temperature monitoring?

Dry-type transformers with epoxy resin cast or insulation paper wrapped windings dissipate heat through natural convection or forced air cooling, exhibiting low surface temperatures with high internal temperatures. Monitoring technology must address: (1) Hot spot location – sensors should approach innermost winding layers or embed during manufacturing; (2) Ambient temperature compensation – systems must simultaneously monitor environmental temperature for correction; (3) Overload dynamic response – monitoring requires <1-second response tracking rapid temperature rise; (4) Sensor miniaturization – limited winding gap spacing necessitates ≤3mm diameter micro-probes.

How should transformer temperature alarm thresholds be scientifically configured?

Threshold configuration follows “baseline temperature + temperature rise limit” עקרונות: (1) Establish baseline data – newly commissioned transformers operate one week at rated load recording steady-state temperatures; (2) Reference manufacturer specifications – oil-immersed transformer top oil generally not exceeding 95°C, winding hot spots not exceeding 98°C; dry-type transformer winding limits based on insulation class (F-class 155°C, H-class 180°C); (3) אזעקות רב רמות – yellow warning = baseline +15°C, orange alarm = baseline +25°C, red emergency = approaching insulation class limits; (4) Temperature differential alarms – any phase exceeding others by 15°C triggers asymmetry warning; (5) התאמה עונתית – appropriately relax thresholds 5-10°C during high summer ambient temperatures. Request detailed alarm configuration guidance.

How do monitoring systems achieve protection device interlocking?

Interlocking realized through dry contact outputs or communication protocols: (1) Dry contact method – monitoring host provides relay contact outputs (orange alarm, red emergency separate contacts) directly connected to transformer protection device digital inputs triggering trip or blocking logic; (2) Communication method – monitoring systems transmit temperature data and alarm information real-time to protection devices and comprehensive automation systems via IEC 61850 GOOSE messages or Modbus protocol supporting complex interlocking strategies including: reducing protection settings during temperature overruns, starting backup coolers, issuing remote dispatch load transfer instructions; (3) Safety principles – protection interlocking logic requires time delay confirmation (לְמָשָׁל, continuous 30-second overrun) avoiding transient disturbance misoperation; critical applications recommend “two-out-of-two” redundant criteria.

What routine maintenance does the monitoring system require?

Fluorescent fiber optic monitoring systems feature maintenance-free design, but recommend periodic inspections: (1) Monthly checks – log into monitoring software verifying all channel data normal, no channel offline alarms, historical curves reasonable; (2) Quarterly checks – compare three-phase temperature symmetry, inspect display terminal working condition, test alarm output functions; (3) Annual checks – coordinate with transformer preventive testing, verify sensor installation positions not loose, fiber protection conduits undamaged, demodulation unit dust cleaning; (4) Calibration cycles – fluorescent fiber optic sensors require no regular calibration, only when measurement deviation suspected use standard temperature source comparison verification; (5) Spare parts reserves – recommend stocking 1-2 spare sensor probes, 1 spare fiber patch cord, 1 backup software program.

Can already-commissioned aging transformers retrofit online monitoring systems?

Retrofitting completely feasible but requires: (1) Outage window – sensor installation requires transformer de-energization, ניקוז שמן (oil-immersed type) or opening enclosures (סוג יבש), necessitating coordinated maintenance timing; (2) Installation space – aging transformers designed without monitoring provisions require field evaluation whether windings, תותבים, tank tops have sufficient space installing sensors and sealed fittings; (3) Tank penetrations – oil-immersed transformers adding oil-immersed sensors require welding flange penetrations on tank tops or sides, must be performed by certified welders following pressure vessel codes with post-penetration pneumatic leak testing; (4) ניתוב סיבים – retrofit projects face field condition fiber route constraints requiring flexible planning with possible additional protective cable trays; (5) Investment return – for aging transformers exceeding 15-year service with high criticality, retrofitting online monitoring enabling condition-based maintenance significantly reduces sudden failure risks with typical 2-3 year payback periods. Request retrofit feasibility assessment.
