MNS Low Pressure Extraction Switch Txee

Txheej txheem cej luam:

MNS hom qis-voltage rho tawm switchgear (tom qab no hu ua switchgear yog tsim los ntawm peb lub tuam txhab tom qab kev txhim kho zoo raws li MNS· series low-voltage switchgear los ntawm AB Company ntawm Switzerland, uas yog qhov siab tshaj qis tshaj -voltage rho switchgear nyob rau hauv Suav teb. Cov khoom lag luam txhim khu kev qha ntawm cov khoom siv hluav taws xob sib txuas tau tsim los ntaus ntawv, ua rau cov neeg siv kev nyab xeeb thiab txhim khu kev qha hauv kev siv.

Lub txee hloov no yog tsim rau AC 50 (60) Hz, ntsuas ua haujlwm voltage 400V. Nyob rau hauv 660 v, ntsuas tam sim no 5000 ib peb -theem tsib xaim ntawm cov hluav taws xob hluav taws xob, tuaj yeem siv rau hauv cov chaw tsim hluav taws xob, cov chaw ua haujlwm, cov chaw lag luam thiab tsuas, cov tsev, tsev so, tshav dav hlau, chaw nres nkoj, thiab xov tooj cua thiab TV kev sib txuas lus, xws li kev tsim hluav taws xob, kev xa tawm thiab kev faib tawm, kev hloov hluav taws xob thiab cov khoom siv hluav taws xob siv hluav taws xob, thiab los ntawm cov nyiaj them rov qab rau lub tsheb loj {7}. Ua raws li cov qauv hauv tebchaws: GB7251.1 "Low-voltage switchgear" IEC60439 "low-voltage switchgear thiab tswj cov khoom"

Cov xwm txheej siv li qub:

3.1 qhov kub ntawm huab cua puag ncig yuav tsum tsis txhob siab tshaj +40 degree, tsis tsawg tshaj li -5 degree, thiab qhov nruab nrab kub nyob rau hauv 24n yuav tsum tsis txhob siab tshaj +35 degree

3.2 Cov av noo nyob ib puag ncig tsis tshaj 50% thaum qhov kub siab tshaj yog +40 degree, thiab nws yog siab dua thaum kub qis dua, xws li 90% thaum kub yog +20℃. Txawm li cas los xij, txiav txim siab tias qhov nruab nrab condensation yuav qee zaus tshwm sim vim qhov kub thiab txias, qhov txheeb ze av noo ntawm cov huab cua ib puag ncig tsis tshaj 50% thaum qhov kub siab tshaj yog +40℃.

3.3 Rau kev siv sab hauv tsev, qhov siab ntawm qhov chaw yuav tsum tsis pub tshaj 2000m.

3.4 Nws yuav tsum tau muab tso rau hauv qhov chaw uas tsis muaj kev vibration hnyav thiab cuam tshuam, thiab qhov twg cov khoom siv hluav taws xob tsis corroded.

Khoom qauv:

Vim qhov kev taw qhia ntawm ABB Switzerland cov thev naus laus zis siab heev, thiab ntawm nws lub hauv paus tseem ceeb los txhim kho cov thev naus laus zis, ua kom nws ua tau raws li Tuam Tshoj lub teb chaws cov xwm txheej. Txee muab nws tus kheej rau hauv lwm txoj hauj lwm nrog 25 hli rau lub modulus ntawm C profiles los ntawm haum rau daim ntawv kom tau raws li ntau yam kev xav tau ntawm txhua yam ntawm cov qauv thiab cov tub rau khoom, lub MCC txee siv lub siab zog ntawm nplaim retardant engineering plastics Cheebtsam, ua rau nws kev ruaj ntseg kev ua tau zoo yog ntau txhim khu kev qha, tib lub sij hawm, ua ke nrog txawv teb chaws muaj nuj nqi board yuav muab retrofit 200 mm, raws li zoo raws li rau PC 2. txee Cov qauv tsim ntawm cov txee sib xyaw, chav rho tawm thiab cov txee muaj cov cuab yeej sib cuam tshuam, txhawm rau tiv thaiv kev hloov pauv hauv lub xeev ntawm lub zog nrog kev thauj khoom rub, txhim kho nws txoj kev nyab xeeb, ntxiv rau, lub txee feem ntau sib sau ua ke nrog txias dov steel phaj passivation kev kho mob, tab sis kuj raws li cov kev xav tau sib txawv ntawm cov neeg siv siv aluminium zinc steel phaj . 5.1 Hloov Txee hom A, hluav taws xob, kev sib txuas hauv tsev thiab ntau yam kev sib txuas lus RMW1, CW1, NA1, DW45, CDW7, MT, E series ntawm Circuit Court breakers ua lub ntsiab hloov, kom ua tiav lub zog lossis kev sib txuas ntawm lub tsheb npav. B. Fais fab chaw txee (PC) txais ntau hom txee khib Circuit Court breakers hauv tsev thiab txawv teb chaws, xws li DW45, NA1, CDW7MT, E series Circuit Court breakers rau kev faib khoom. C. Lub chaw tswj lub cev muaj zog (MCC) yog sib dhos los ntawm cov tub rau khoom. Lub ntsiab hloov ntawm txhua lub voj voog txais cov yas- rooj plaub Circuit Court breaker nrog lub peev xwm tawg siab lossis kev hloov pauv hloov nrog fuse. A, reactive fais fab nyiaj them txee 5.2 tub rau khoom hom muaj tsib qhov ntau thiab tsawg yog 8E (200mm) qhov siab, qauv qauv tsim, nws cov khoom siv tau zoo installation qhov siab yog 1800mm, kom tag nrho cov txheej txheem ntawm lub txee yog qhov tsim nyog, zoo nkauj dua 8E / 4: siab 200 × dav 150 X qhov tob 4004 qhov siab qhov sib txuas 2 0. 300 x D 400 qhov siab qhov chaw Parallel ua ke 2 tub rau khoom 8E: H 200x w 600 x D 400 qhov siab qhov chaw sib dhos 1 tub rau khoom 16E: Qhov siab 400x dav 600x qhov tob 400 qhov siab qhov chaw sib dhos 1 tub rau khoom qhov tob 24E: qhov siab 600x qhov dav 401 ntawm qhov siab 24E (600mm) qhov siab.
