126kV 145kV mataas na boltsing SF6 circuit breaker

Pagpapakilala sa Produkto：

Ang LW36-126(145)(W) circuit breaker ay isang higit na maunlad na elektrikal na aparato na disenyo para sa maraming aplikasyon sa mga sistema ng kuryente. Ang breaker na ito ay angkop para sa pag-operate ng single-phase, three-phase electrical linkage, at three-phase mechanical linkage, na itinayo para sa grid frequencies ng 50/60Hz sa neutral-grounded at neutral-ungrounded systems. Ito ay sumisikat sa mga mahirap na scenario, may C2-level capabilities para sa back-to-back capacitor bank switching, no-load line-charging breaking, at no-load cable-charging breaking—nagpapatupad ng pinakamataas na internasyonal na pamantayan para sa reliabilidad at performance.

Angkop para sa single-phase/three-phase (electrical/mechanical) operation sa 50/60Hz grids (neutral-grounded/ungrounded systems). Nagpapatupad ng C2-level standards para sa back-to-back capacitor bank, no-load line/cable switching.

Mga Katangian

• Arc Extinguishing: SF6 gas + self-energy technology para sa mababang power consumption, 40kA short-circuit breaking (22x consecutive without maintenance).

• Mechanism: Spring actuating system na may 10,000-cycle mechanical life (M2 class), mababang ingay (<65dB), at compact design (30% mas maliit kaysa sa tradisyunal na modelo).

Reliabilidad:

• Seismic: Nagsasalig sa IEEE693-2018 1.0g at ETG Chile standards.

• Insulation: Creepage distance >31mm/kV, nag-ooperate sa ≤3000m altitude, anti-pollution design.

• Sealing: SF6 annual leakage rate <0.5%, strict dehumidification (moisture content below industry norms).

Mga Materyales:

• Zinc-base alloy valve plates para sa stable gas dynamics.

• Imported PTFE spouts na may mataas na ablation resistance.

• Stainless steel mechanism cases + hot-galvanized fasteners para sa corrosion resistance.

Maintenance: ≥10-year maintenance-free cycle, 25,000+ global installations, optional phase closing device.

Ano ang mga katangian ng performance ng canister circuit breaker?

Mataas na Insulation Performance：

• Mataas na Insulation Performance: Kung gagamit ng sulfur hexafluoride (SF6) gas o insulating oil bilang insulating medium, ang tank-type circuit breakers ay may mataas na lebel ng insulation. Maaari silang tanggapin ang system operating voltages at iba't ibang overvoltages, nang mapanatili ang kaligtasan ng mga equipment at tao.

Matibay na Arc-Quenching Capability：

• Matibay na Arc-Quenching Capability: Ang espesyal na disenyo ng arc quenching chamber at ang arc-quenching medium ay nagbibigay-daan sa tank-type circuit breakers na mabilis na i-extinguish ang arcs kapag nag-interrupt ng short-circuit currents. Ito ay nagbabawas ng burn damage sa mga contacts, nagpapahaba ng electrical life at interrupting performance ng circuit breaker, at nagbabawas ng downtime at maintenance costs na may kaugnayan sa mga fault.

Mabuting Environmental Adaptability：

• Mabuting Environmental Adaptability: Ang saradong tank structure ay nagbibigay ng mabuting resistance sa contamination, moisture, at windblown sand. Ito ay nagbibigay-daan sa circuit breaker na mag-operate nang matatag sa iba't ibang heograpikal na environment at climatic conditions, kaya ito ay angkop para sa outdoor substations, industrial at mining enterprises, at iba pang lugar.
