35kV Solid Insulated Ring Main Unit/switchgear

Paliwanag

Karakteristik

• Napahusay na performance ng solid insulation para sa 35kV: Ginagamit ang high-strength na solid insulating materials tulad ng epoxy resin, na may espesyal na optimized na insulation structure para sa 35kV voltage level. Ito ay may mataas at matatag na insulation strength, hindi naapektuhan ng environmental factors tulad ng humidity, dust, at contamination. Ito ay maaaring makabuluhang tiyakin ang electrical stress sa ilalim ng mataas na voltage, na siyang nagbabawas ng risks ng flashover at breakdown, at nagbibigay-daan sa long-term reliable operation ng medium at high-voltage power distribution systems.

• Fully eco-friendly na gas-free design: Inabandona ang greenhouse gases tulad ng SF₆, na nagsisilbing pag-alis ng environmental hazards dahil sa gas leakage at subsequent links tulad ng gas monitoring at gas replenishment sa operation at maintenance. Ito ay sumasang-ayon sa international environmental standards at development trend ng green power grids, at lalo na ito ay suitable para sa 35kV power distribution scenarios na may mahigpit na environmental requirements, tulad ng ecological protection zones at urban core areas.

• Compact na high-voltage adaptive structure: Nagsasama ng metal-enclosed shell at modular layout, na siyang nagpapakita ng significant reduction sa equipment volume habang nakakasunod sa 35kV high-voltage insulation distance requirements. Ang floor area nito ay lamang 50%-70% ng traditional open-type equipment, na nagpapadali ng installation sa space-constrained high-voltage power distribution sites tulad ng substations at large industrial plants, at nagpapadali ng site planning at layout.

• Multiple na high-voltage safety protection mechanisms: Nakakamit ng 35kV-specific mechanical at electrical interlocking devices upang maipaglaban ang dangerous operations tulad ng on-load switching, incorrect grounding, at entry into live compartments; ang fully enclosed metal shell ay effective na nag-shield ng high-voltage electric fields, na may built-in high-voltage live display at grounding status monitoring functions, na siyang comprehensive na nag-aasikaso ng seguridad ng operation at maintenance personnel at equipment 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 high-voltage components ay completely isolated mula sa labas, na nagbabawas ng component losses dahil sa high-voltage arcs at environmental erosion. Ito ay maaaring makamit ang maintenance-free operation para sa higit sa 20 taon, na siyang nagbabawas ng life-cycle maintenance costs at shutdown risks ng 35kV equipment.

• Flexible na high-voltage distribution compatibility: Suportado ng multiple 35kV wiring methods tulad ng ring network power supply, dual power supply switching, at radial distribution. Ito ay maaaring seamless na konektado sa transformers, cable branch boxes, GIS equipment, etc., ng parehong voltage level, na siyang nag-aasikaso sa diverse 35kV power distribution needs sa urban medium at high-voltage distribution networks, malalaking industriya, new energy power stations (wind power, photovoltaic), etc.

Paggamit

Ang solid insulated ring main unit ay gumagamit ng rotary fuse structure sa loob, na nagpapadali ng pagpalit ng fuse cabinet type. Ang laki ng device ay ang pinakamaliit sa lahat ng gas-insulated cabinets, ang floor space ay ang pinakamaliit, at ito ay environmentally friendly para sa power supply at distribution ng urban users at residential applications.
