Siv Cov Cai

• Ambient kub: -40 ℃ ~ + 40 ℃ (qis dua -30 ℃ yuav tsum tau sib tham los ntawm cov neeg siv khoom thiab cov chaw tsim khoom);

• Qhov siab:

• Kev siv av qeeg: tsis pub tshaj 8 degrees;

• Qhov nruab nrab cov av noo siab tshaj plaws: 24h nruab nrab

• Qhov chaw tsis muaj hluav taws kub, tawg, tshuaj lom neeg corrosion thiab nquag vibration.

Tus yam ntxwv

• Tag nrho cov khoom siv thiab cov khoom siv insulated tag nrho: Txhua qhov nyob ntawm GRM6-24 raug kaw hauv ib lub thawv welded los ntawm 304 stainless hlau phaj, lub thawv ntim nrog SF6 roj nrog kev ua haujlwm siab ntawm 1.4bar, thiab qib kev tiv thaiv yog IP67. Nws yog qhov tsim nyog rau kev teeb tsa hauv thaj chaw uas muaj cov av noo siab thiab cov pa phem, tshwj xeeb tshaj yog tsim rau cov mines, lub thawv-hom substations thiab txhua qhov chaw uas muaj qhov cuam tshuam rau qhov chaw flashover vim huab cua muaj kuab lom. Cov khoom lag luam tau teeb tsa nrog lub tes tsho DIN47636 tus qauv, thiab txuas nrog lub cable los ntawm cov khoom siv insulated, tag nrho kaw, shielded cable sib koom ua ke.

• Kev ntseeg siab thiab kev nyab xeeb ntawm tus kheej: tag nrho cov khoom nyob tau raug kaw hauv SF6 cua chamber; Cov huab cua chamber muaj kev ntseeg siab nyem channel, uas tau dhau los ntawm 20kA / 0.5s nrog kev ua txhaum arc kuaj: qhov hloov pauv thiab hloov hauv av yog peb txoj haujlwm hloov, uas yooj yim rau kev sib cuam tshuam ntawm lawv. Muaj kev txhim khu kev qha txhua yam cuam tshuam ntawm lub cable compartment cover thiab lub load hloov, uas tuaj yeem tiv thaiv kom tsis txhob nkag mus rau lub sijhawm nyob ntawm qhov yuam kev.

• Kev tu-dawb thiab lub neej ntev lub voj voog Cov khoom tsim nrog lub neej voj voog ntawm 30 xyoo. Thaum lub sij hawm lub voj voog ntawm cov khoom, lub ntsiab hloov tsis tas yuav tsum tau saib xyuas. Tus nqi xau txhua xyoo ntawm cov khoom yog

• Cov qauv compact: Tsuas yog cov khoom siv hluav taws xob hluav taws xob ntsuas cua thiab PT txee, tag nrho cov modules tsuas yog 350mm dav, thiab cable txuas bushings ntawm tag nrho cov units muaj qhov siab tib yam rau hauv av, uas yooj yim rau kev tsim kho ntawm qhov chaw.

• GRM6-24 tuaj yeem teeb tsa nrog cov cuab yeej tswj hwm ntse (yeem), muab kev tiv thaiv zoo, tswj chaw taws teeb thiab saib xyuas, thiab txhawb nqa lub tshuab hluav taws xob automation.

• GRM6-24 muab ob txoj kev tiv thaiv rau transformers: load hloov fuse ua ke thiab Circuit Court breaker nrog relay tiv thaiv. Load hloov fuse ua ke cov khoom siv yog siv rau transformers ntawm 1600kVA thiab hauv qab no, thaum Circuit Court breakers nrog relays yuav siv tau rau transformer tiv thaiv ntau yam peev xwm.

• Kev tiv thaiv ib puag ncig: Kev txhim kho ntawm GRM6-24 suav nrog tsis yog cov khoom siv xwb, tab sis kuj tseem muaj kev tiv thaiv ib puag ncig los ntawm cov txheej txheem tsim khoom mus rau lub neej ua haujlwm ntawm kev hloov. Tag nrho cov ntaub ntawv raug xaiv los ua tus phooj ywg ib puag ncig, thiab cov txheej txheem ntxuav xoom xoom raug saws. Cov khoom raug kaw rau lub neej, thiab 90% mus rau 95% ntawm cov khoom tuaj yeem rov ua dua tom qab qhov kawg ntawm cov khoom lag luam lub neej.

Main Technical Parameters
