Plug-and-Play CT Module: Isang Nagbabagong Solusyon para sa Mabilis na Pagsasauli ng GIS Current Transformer
Plug-and-Play CT Module Rapid Replacement Solution: Revolutionizing Efficient Maintenance for GIS Current Transformers
Sa mga high-reliability power scenarios tulad ng nuclear power plants at data centers, bawat minuto ng downtime ng equipment ay maaaring magresulta sa significant economic losses o safety hazards. Kapag ang traditional GIS current transformers (CTs) ay nagkaroon ng pagkakamali, ang buong gas compartment ay kailangang idepressurize at i-isolate para sa replacement, isang proseso na nagsasahimpapawid ng ilang araw. Ang solusyon na ito ay gumagamit ng innovative plug-and-play CT module design upang makamit ang 90% reduction in maintenance time, na sumasagot sa pangunahing operational challenge sa GIS system maintenance.
Key Technical Highlights
- Ultra-Fast Installation/Removal - Quick-Release Metal-Sealed Bellows Interface
- Modular CT gas chamber interface na nagbibigay-daan sa physical isolation; ang pagtanggal ay hindi nangangailangan ng depresurization ng main GIS gas compartment.
- Metal-sealed bellows structure na nag-uugnay sa permanent elasticity at insulation performance sa range ng -40°C hanggang 105°C.
- Dedicated hydraulic separation tools na nagbibigay-daan sa damage-free separation ng gas-tight surfaces; ang buong proseso ng pagtanggal/pag-install ay nagsasahimpapawid ng <120 minutes (vs. ~72h para sa traditional solutions).
- Plug-and-Play Operation - Calibration-Free EEPROM Technology
- Industrial-grade AT24C512 chips na embedded sa CT secondary windings na pre-store calibration parameters (linearity compensation ±0.1%, phase compensation angle <2 arcminutes).
- Automatic matching sa GIS measurement/control units upon connection, na nagwawala sa traditional current ratio/phase error verification steps.
- Supports 30,000 read/write cycles na may >25-year data retention period.
- Field Verification - Portable Calibration System
- Handheld injection tester na nag-output ng 0.5~5000A adjustable current (Class 0.05 accuracy), na sumasagot sa IEC 61869-2 testing requirements.
- Automatic comparison ng operational parameters laban sa EEPROM reference values; ang accuracy verification ay natatapos sa <30 minutes.
- Bluetooth transmission ng reports sa operation & maintenance (O&M) platforms para sa generation ng digital maintenance records (ISO 55001 compliant).
