40.5kV Solid Insulated Switchgear/ Ring Main Unit

Pangungusap

40.5kV Solid Insulated Switchgear：Ang serye ng FYG solid insulated switchgear ay angkop para sa medium voltage power distribution system na may rated current ng 630A/1250A. Ito ay mas maasahan kaysa sa SF6 ring main unit, at mas angkop para sa mas malawak na aplikasyon ng mga pamantayan ng GB at IEC.

Karakteristik

• Solid insulation performance na naka-adopt para sa 40.5kV high voltage: Gumagamit ng high-strength solid insulating materials tulad ng epoxy resin, na may optimized insulation design para sa 40.5kV high-voltage level. Ito ay may matatag na insulation strength, hindi naapektuhan ng environmental factors tulad ng humidity at contamination, na nagbabawas ng risks ng flashover at breakdown sa ilalim ng mataas na voltage, at nag-aalamin ng reliable operation ng high-voltage power distribution systems.

• All-condition eco-friendly gas-free design: Inabandona ang greenhouse gases tulad ng SF₆, na sumisira sa environmental hazards at operation/maintenance risks dahil sa gas leakage. Ito ay sumasang-ayon sa international environmental regulations at green power grid construction requirements, at partikular na angkop para sa high-voltage distribution scenarios na sensitibo sa environmental protection, tulad ng ecological protection zones at urban core areas.

• Compact high-voltage adaptive structure: Naglalaman ng metal-enclosed shell at modular layout, na nagbibigay ng significant reduction sa volume habang nasasapat ang 40.5kV high-voltage insulation distance. Ang floor area nito ay tanging 60%-70% ng traditional equipment, na ginagawang ito angkop para sa space-constrained high-voltage distribution sites tulad ng substations at large industrial parks, simplifying installation layouts.

• Multiple high-voltage safety protection mechanisms: Nakakamit ng high-voltage-specific mechanical at electrical interlocks upang mahigpit na i-prevent ang dangerous actions tulad ng on-load operation at incorrect grounding; ang fully enclosed metal shell ay nagshields ng high-voltage electric fields, na may built-in high-voltage live display at grounding status monitoring, na nag-aalamin ng comprehensive operation at maintenance safety sa high-voltage environments.

• Long-life at low-maintenance characteristics: Ang solid insulating materials ay may excellent anti-aging at corrosion-resistant properties; ang core components ay completely isolated mula sa labas, na nagbabawas ng losses dahil sa high-voltage arcs at environmental erosion. Ito ay nag-aalamin ng maintenance-free operation para sa higit sa 20 taon, na nagbabawas ng whole-life-cycle cost ng high-voltage equipment.

• Flexible high-voltage distribution compatibility: Sumusuporta ng multiple high-voltage wiring methods tulad ng ring network, dual power supply, at radial type, at maaaring seamless na konektado sa 40.5kV transformers, cable branch boxes, at iba pang equipment. Ito ay nag-aalamin ng diverse high-voltage distribution needs sa urban high-voltage distribution networks, large industrial enterprises, new energy power stations, atbp.
