40.5kV mataas na boltag SF6 circuit breaker

Pagpapakilala sa Produkto：

Ang LW36-40.5 outdoor self-energy HV AC SF6 circuit breaker usa ka outdoor three-phase HV AC equipment nga gigamit sa electricity grids nga adunay altitudes nga dili mas taas sa 3000m, environment temperatures nga dili mas baba sa -40℃, local pollution classes nga dili mas taas sa Class IV, ug AC 50Hz/60Hz nga may maximum voltage nga 40.5kV, kini ang suitable sa control ug protection sa HV supply ug transformation lines sa power station, converting stations, ug industrial ug mining enterprises. Kini usab mahimong gamiton isip connection circuit breaker.

Pangunhing Katangian：

Ang LW36-40.5 self-energy HV SF6 circuit breaker gisulod og advanced hot-expansion plus auxiliary pressure gas self-energy arc extinguishing technology ug matched sa new-type spring actuating mechanism, kini adunay mga katangian sama sa long electrical endurance, small operating power, high electrical ug mechanical reliability, high technical parameters, ug moderate price. Ang iyang pangunhing performance features mao kini:

• High rated technical parameters: rated current 2500A/4000A ug rated short circuit breaking current 31.5KA/40KA/50KA.suitable sa pagbukas ug pagpadara sa large-capacity electricity grids.

• High electrical reliability：

No-load line charging breaking ability ug no-load cable charging breaking ability 50/60Hz dual-frequency C2，back-to-back capacitor bank breaking ability 50/60Hz dual-frequency C2, walay re-breakdown;

Strong external insulation ability;, suitable sa regions nga adunay 3000m altitude o Class lV pollution.

• High reliability of operating mechanism:

Mechanical endurance: separating ug closing for 10000 times without replacing parts; mahimo mopasabot sa user' s requirement sa continuous running ug little maintenance.

New type spring actuating mechanism adunay few components parts; overall high-strength cast aluminum frame ug brake separating ug closing spring; ug centralized arrangement is adopted for the buffer, compact structure, reliable operation, low noise, ug convenient maintenance; suitable sa frequent operations.

• Al exposed parts gihimo sa stainless steel materials o hot-galvanized on the surface para sa high corrosion resistance.

• Reliable sealing structure ensures the product annual leakage rates≤0.5%.

• Four internally attached current mutual inductors for every phase mahimo mapasabot sa circuit breaker. Microcrystal alloy ug high permeability material giadopt sa internally attached current mutual inductors. The accuracy of 200A ug above current mutual inductors mahimo mapasabot sa Level 0.2 or 0.2S. Reliable electrical screening design giadopt sa cable coils sa internally attached current mutual inductors aron mapahimulos ang electric field distribution sa mutual inductors ug promote ang internal insulation sa product. kini mahimo magbuhat 120kv ug 5min working frequency withstand voltage test ug ang internal insulation dili mag-interfere sa short circuit breaking working conditions, kini nagbutang sa safe ug reliable.

 Unsa ang application fields sa tank circuit breakers？

Power Transmission ug Distribution：

• Power Transmission ug Distribution: Sa high-voltage ug ultra-high-voltage transmission lines, ang tank-type circuit breakers gigamit aron kontrolhon ug protektahan ang transmission sa electricity. Kini mahimo mogamit sa pagconnect ug pagdisconnect sa circuits sa normal operation ug quickly interrupt fault currents kung may faults, ensuring ang stable operation sa power system.

Substations：

• Substations: Isip usa sa core devices sa substations, ang tank-type circuit breakers molabor sa uban pang electrical equipment aron kontrolhon ug protektahan ang busbars, incoming ug outgoing lines sa uban-uban nga voltage levels sa substation. Kini nagensure sa safe ug reliable distribution ug conversion sa electrical energy.

Industrial Power Supply：

• Industrial Power Supply: Sa power supply systems sa large industrial ug mining enterprises, ang tank-type circuit breakers mahimong gamiton aron protektahan ang important electrical equipment ug production lines, preventing ang power outages gikan sa short-circuit faults ug uban pang issues. Kini nag-enhance sa continuity ug stability sa production.
