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

Product introduction：

Ang LW58-252(W) outdoor self-energy high-voltage SF₆ circuit breaker ay gin disenyo para sa 252kV, 50Hz AC power systems, na naglilingkod bilang isang mahalagang kontrol at proteksyon na device para sa interconnection ng power grid. Gamit ang SF₆ gas para sa arc quenching at insulation, ito ay mayroong self-energy power arc extinguishing double-action interrupter structure kasama ng bagong uri ng spring operating mechanism. Kilala ito dahil sa kanyang matibay na switching capability, mababang operating power, mababang ingay, at mataas na reliabilidad, ang kanyang teknikal na indicators ay naka-align sa mga advanced domestic at international counterparts.

Ang three-phase SF₆ circuit breaker na ito ay nag-upgrade mula sa single-pole, single-mechanism operation patungo sa three-phase mechanical linkage system na pinapatakbo ng isang mechanism. Ang disenyo na ito ay nagbabawas ng mechanical complexity, nagpapataas ng three-phase linkage reliability, at nagwawala ng panganib ng single-phase misoperation.

Main characteristic：

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

• High Operational Efficiency: Nangangailangan lamang ng minimal 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, nakakatipon ng mataas na temperatura, mababang 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 na ang SF₆ moisture content ay mas mababa pa sa industry standards.

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

Advanced Materials:

• 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 nagbibigay ng 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, ang key components ay resist wear, ensuring low failure rates during frequent operations.

What are the main types of 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 nagpapahintulot nito na matugunan ang high voltage at high current breaking at insulation requirements sa small space. Ito ay malawak na 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 pag-extinguish 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 bumababa. Sa kasalukuyan, ito ay pangunihin na ginagamit sa specific situations kung saan ang fire prevention requirements ay hindi stringent.
