126kV 145kV mataas na tensyon na SF6 circuit breaker

Product introduction：

Ang LW36-126(145)(W) circuit breaker ay isang nangungunang elektrikal na aparato na disenyo para sa maraming aplikasyon sa mga sistema ng kuryente. Ang breaker na ito ay angkop para sa operasyong single-phase, electrical linkage ng three-phase, at mechanical linkage ng three-phase, at ito ay optimized para sa grid frequencies na 50/60Hz sa mga neutral-grounded at neutral-ungrounded systems. Ito ay nakakamit ang C2-level capabilities para sa back-to-back capacitor bank switching, no-load line-charging breaking, at no-load cable-charging breaking—na sumasagot sa pinakamataas na international standards para sa reliabilidad at performance.

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

Features

• 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 traditional models).

Reliability:

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

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

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

Materials:

• 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.

What are the performance characteristics of the canister circuit breaker？

High Insulation Performance：

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

Strong Arc-Quenching Capability：

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

Good Environmental Adaptability：

• Good Environmental Adaptability: Ang enclosed tank structure ay nagbibigay ng excellent resistance sa contamination, moisture, at windblown sand. Ito ay nagbibigay-daan para sa circuit breaker na gumana nang maayos sa iba't ibang geographical environments at climatic conditions, na ginagawang ito ay angkop para sa outdoor substations, industrial and mining enterprises, at iba pang lokasyon.
