40.5kV Solid Insulated Switchgear/ Ring Main Unit

Paliwanag

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 na 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 nauugnay sa 40.5kV high voltage: Ginagamit ang high-strength solid insulating materials tulad ng epoxy resin, na may insulation design na optimized 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 high voltage, at nag-aasikaso ng reliable operation ng high-voltage power distribution systems.

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

• Compact high-voltage adaptive structure: Naglalabas ng metal-enclosed shell kasama ng modular layout, na nagsisiguro ng maliit na volume habang sinusunod ang 40.5kV high-voltage insulation distance. Ang floor area nito ay lamang 60%-70% ng traditional equipment, na siyang angkop para sa space-constrained high-voltage distribution sites tulad ng substations at large industrial parks, na simplifies ang 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 nag-shield ng high-voltage electric fields, na may built-in high-voltage live display at grounding status monitoring, na comprehensive na nag-aasikaso ng 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 ganap na isolated mula sa labas, na nagbabawas ng losses dahil sa high-voltage arcs at environmental erosion. Ito ay nag-aasikaso ng maintenance-free operation na higit sa 20 taon, na significantly 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-aasikaso ng diverse high-voltage distribution needs sa urban high-voltage distribution networks, large industrial enterprises, new energy power stations, atbp.
