I. Tattalin Yawan Kudin Da Hanyar Tsarin
- Tsarin da Hanyar Ilimi
- Amfani da taurorin ilimi na al'adu (kamar ANSYS, COMSOL) don in kula da inganci insulator da kuma gaba-gaban. Samun daidaitaccen tsari na insulator, shed profile, da wall thickness. Yana koyar da abubuwa mai lilo bayan fitar da IEC/CNS standards, wanda ya koyar da kudin raw materials da 15%-20%.
- Babu Lafiya: Tsarin da ake sautansu suna dole daga cikin duk fannonin nuna, sama da power frequency withstand, lightning impulse, da pollution tests.
- Tattalin Zabbar Insulator
- Masana Mai Zafi (ESDD ≤ 0.1mg/cm²): Amfani da insulator mai zafi (silicone rubber material) don in koyar da insulator mai harshe:
✓ Yawan koyar da 40% → Yana koyar da kudin tasiri da kuma ƙofin aiki.
✓ Hydrophobicity yana ɗaukan zafi flashover → Yana koyar da kudin ƙofin sojo.
✓ Yawan koyar da ƙarfin kusa → Yana koyar da ƙofin ƙasa daidai saboda kusa.
Yawan koyar da ƙofin yana koyar da 30% zuwa insulator mai harshe.
II. Masanaicin O&M Don In Koyar Da Kudin
- Tsarin da Babu Aiki Da Hanyar Ilimi
- Tsarin da Babu Core-Lifting: Tanki mai shiga yana amfani da bellows-type expansion device + dual sealing rings, wanda ya koyar da aiki da core-lifting a lokacin shekaru 30. Yana koyar da ƙofin core-lifting (≈ $5,000/instance) da kuma ƙofin outage.
- Modular Desiccant Unit: Respirator desiccant zai iya canzawa a matsayin ƙarin (< 30 minutes), bata da lafiya mai ma'ana. Yana koyar da ƙofin O&M da 70%.
- Ilimi Mai Tsari Na Koyar Da Hanyar Ilimi
- Integrated Monitoring Interfaces: Pre-wired interfaces for oil pressure/moisture/oil level sensors (IEC 61850 compliant), supporting integration with SCADA systems.
- Basic Configuration: Standard mechanical oil gauge, pressure gauge, and moisture indicator for "visual" rapid diagnostics.
- Benefits: Provides early warning of insulation degradation, reducing unplanned outages by ≥90% and lowering fault repair costs by 50%.

Tattalin Koyar Da Hanyar Ilimi |
TCO Contribution |
|
Low-loss Supermalloy Core |
No-load loss reduced by 40% compared to national standards. 30-year energy savings offset the initial investment premium. |
|
High-Reliability Branded Components |
MTBF ≥ 500,000 hours. Reduces fault replacement costs and outage losses ($100k+/instance). |
IV. Tattalin Koyar Da Hanyar Ilimi (Misal)
Assume a 220kV VT project:
TCO = Procurement Cost + Σ(t=1 to 30) [Annual O&M Cost / (1+r)^t] + Outage Loss Costs
(Where r = Discount Rate)
Key Parameters:
- Energy Savings: Low-loss design saves ≈ 1,200 kWh/year (≈$600/year).
- Reliability Gain: High-reliability brand ensures fault rate ≤ 0.2% → Reduces outage losses by $500k over 30 years.
Result: Investment payback period < 8 years. Total lifecycle cost reduced by 18%-25%.
Summary
This solution leverages four pillars – design-source cost reduction (material optimization), O&M structural innovation (core-lifting free + modularity), continuous energy consumption control (low-loss core), and a fault prevention system (condition monitoring + high reliability) – to compress the total lifecycle cost of outdoor VTs/PTs by over 20%, while ensuring safety and reliability. It provides power grid enterprises with an economically proven solution validated over 30 years.
Reference Standards: IEC 60044-2, GB/T 20840.2, CIGRE TB 583
Applicable Scenarios: 110kV~500kV substations, renewable energy booster stations, high-pollution industrial areas.
