FZW28-12F sab nraum zoov high voltage faib lub tshuab nqus tsev load hloov

FZW28-12F series sab hauv tsev high-voltage isolating switchgear siv rau hauv cov tshuab fais fab nrog rated voltage ntawm 12KV, AC 50Hz thiab qis dua. Nws yog siv los qhib thiab kaw cov circuits thaum muaj voltage tab sis tsis muaj load. Nws kuj muaj cov khoom lag luam xws li anti-pollution high-altitude hom thiab nruab nrog lub cuab yeej tso saib nyob.

Cov koob ntawm cov disconnectors no yog peb-pole hom, muaj ib lub chassis, ib lub rotating ncej, ib lub lever, ib lub porcelain support insulator, ib lub riam switch thiab ib lub terminal block. Lub rotating ncej yog muab tso rau ntawm lub chassis, uas peb khub ntawm levers yog welded, thiab cov levers yog txuas nrog lub riam switch los ntawm ib tug rub pas nrig porcelain insulator. Lub rotating ncej txuas ntxiv tawm ntawm lub chassis, thiab txhua qhov ntawm nws tuaj yeem txuas nrog lub operating mechanism.

    Cov yam ntxwv

    1. Kev thaiv qhov txhaum luv luv ntawm interphase: Thaum muaj qhov txhaum luv luv tib yam tshwm sim hauv kab ceg ntawm tus neeg siv, lub qhov hloov ciam teb yuav raug qhib thiab xauv tam sim ntawd tom qab lub tshuab hluav taws xob substation lossis lub cuab yeej tiv thaiv rov qab. Tom qab lub chaw nres tsheb rov qab kaw, lub zog muab rau lwm tus neeg siv ceg ntawm kab pub mov yuav rov qab los sai sai;

    2. Nrhiav qhov chaw ua txhaum sai sai: Tom qab lub qhov hloov pauv ciam teb raug qhib vim muaj xwm txheej ntawm cov kab hluav taws xob, tus neeg siv lub luag haujlwm yuav raug txiav tawm ntawm lub zog thiab yuav siv zog los tshaj tawm cov ntaub ntawv xwm txheej. Cov neeg ua haujlwm ntawm lub tuam txhab fais fab tuaj yeem siv lub khoos phis tawj lossis lub module sib txuas lus los tshawb xyuas qhov ua rau muaj xwm txheej ntawm qhov chaw;

    3. Txiav tawm qhov txhaum av ib theem xwb: Thaum muaj qhov txhaum av ib theem xwb tshwm sim hauv tus neeg siv kab ceg, qhov hloov ciam teb yuav qhib tau;

    4. Lwm cov neeg siv ceg ntawm lub substation thiab feeder kab tsis tuaj yeem hnov ​​​​​​qhov tshwm sim ntawm qhov txhaum. Lub pob hloov no tuaj yeem ua tiav cov haujlwm hauv qab no: kev tiv thaiv sai-tawg, kev tiv thaiv overcurrent, peb-lub sijhawm rov kaw, kev kaw cov xwm txheej, kev tiv thaiv tiv thaiv surge, xoom-sequence tiv thaiv, lub moos tiag tiag, kev nrawm tom qab rov kaw, kev nug xwm txheej tiag tiag, kev tswj hwm lub computer ntse, kev teeb tsa hauv zos / chaw taws teeb ntawm cov nqi ruaj khov, kev tshaj tawm qhov txhaum nquag, thiab GSM luv luv message function.

    Ib puag ncig siv

    ◆Qhov kub ntawm huab cua ib puag ncig: qhov siab tshaj plaws +40 ℃, qhov qis tshaj plaws -40 ℃;

    ◆Tus nqi av noo: tus nqi nruab nrab txhua hnub tsis pub tshaj 95%, tus nqi nruab nrab txhua hli tsis pub tshaj 90%:

    ◆Qhov siab: ≤3000m;

    ◆ Cua siab: tsis pub tshaj 700Pal (sib npaug rau cua ceev 34m/s):

    ◆ Qib kev ua qias tuaj: Qib Ⅳ (qhov deb ntawm qhov nkag mus> 31mmvkV);

    ◆Tuab dej khov: ≤ 10 hli

    ◆Txoj kev av nruab nrab: qhov nruab nrab tsis tau av, qhov nruab nrab tau av los ntawm arc suppression coil, qhov nruab nrab tau av los ntawm kev tiv thaiv qis.
