252kV outdoor self-energy power high voltage SF6 circuit breaker 252kV outdoor self-energy power mataas na boltag SF6 circuit breaker

Pagpapakilala sa Produkto：

Ang LW58-252(W) outdoor self-energy high-voltage SF₆ circuit breaker ay disenyo para sa 252kV, 50Hz AC power systems, na nagsisilbing mahalagang kontrol at proteksyon device para sa interconnection ng power grid. Gumagamit ito ng SF₆ gas para sa pagquench ng arc at insulation, mayroon itong self-energy power arc extinguishing double-action interrupter structure kasama ang bagong spring operating mechanism. Kilala ito sa kanyang matibay na switching capability, mababang operating power, mababang ingay, at mataas na reliability, ang mga teknikal na indikador nito ay tugma sa advanced domestic at international counterparts.

Ang three-phase SF₆ circuit breaker na ito ay nag-upgrade mula sa single-pole, single-mechanism operation hanggang sa three-phase mechanical linkage system na pinapatakbo ng isang mechanism. Ang disenyo na ito ay binawasan ang mechanical complexity, pinaunlad ang three-phase linkage reliability, at inalis ang panganib ng single-phase misoperation.

Pangunahing Katangian：

• Self-Energy Arc Extinguishing Technology: Ang double-action structure ay sigurado sa stable breaking capacity sa iba't ibang loads.

• Mataas na Operational Efficiency: Nangangailangan lamang ng kaunti operating power, may mechanical life cycle na hanggang 10,000 cycles para sa prolonged reliability.

• Superior Contact Design: Ang copper-tungsten arc contacts ay gumagamit ng integral sintering, nakakatagal ng mataas na temperatura, minimal arc erosion, at higit sa 20 full breaking operations.

Reliable Sealing & Insulation:

• Annual SF₆ gas leakage rate < 0.5% sa pamamagitan ng precision sealing technology.

• Mahigpit na dehumidification processes na sigurado ang SF₆ moisture content na mas mababa pa sa industry standards.

• Mataas na insulation level na creepage distance > 31mm/kV.

Advanced Materials:

• Ang arc extinguishing chamber valve plates ay gumagamit ng lightweight zinc-base alloy para sa stable gas dynamics at breaking performance.

• Imported PTFE-composite nozzles na may excellent ablation resistance at consistent arc quenching.

• Premium Components: Secondary circuit electrical units at SF₆ density relays ay high-quality impact-resistant o joint-venture products.

• Pure Spring Operating Mechanism: Forged mula sa high-strength alloy steel, key components na resist wear, ensuring low failure rates during frequent operations.

Ano ang pangunahing uri ng tank circuit breakers？

SF6 Gas-Insulated Circuit Breaker：

• SF6 Gas-Insulated Circuit Breaker: Gumagamit ng sulfur hexafluoride (SF6) gas bilang insulating at arc-quenching medium. Ang SF6 gas ay may excellent insulating properties at arc-quenching capabilities, na nagbibigay dito ng kakayahang sumunod sa high voltage at high current breaking at insulation requirements sa small space. Ito ay malawakang ginagamit sa high-voltage at ultra-high-voltage power systems.

Oil-Immersed Circuit Breaker：

• Oil-Immersed Circuit Breaker: Gumagamit ng insulating oil bilang insulating at arc-quenching medium. Ang insulating oil ay may good insulating properties at heat dissipation capabilities, na effective sa pagquench ng arcs at cooling ng contacts. Gayunpaman, dahil sa fire risk at environmental pollution na kaugnay ng insulating oil, ang application range nito ay unti-unting bumaba. Sa kasalukuyan, ito ay pangunahing ginagamit sa specific situations kung saan ang fire prevention requirements ay hindi stringent.
