Txheej txheem cej luam
YN28-12 armored tshem tau AC hlau-kab switchgear.Nws yog tsim rau peb-theem AC fais fab system nrog ntsuas voltage ntawm 12kV thiab ntsuas zaus ntawm 50Hz.Nws yog siv los txais thiab faib hluav taws xob hluav taws xob thiab tswj, tiv thaiv thiab saib xyuas cov circuits.
Standards ua raws:
GB3906-2006 "3.6 ~ 40.5kV AC hlau-kaw switchgear thiab tswj cov cuab yeej" GB11022-89 "Cov kev cai dav dav rau high-voltage switchgear" IEC298 (1990) "Rated voltage saum 1kV thiab 50kV thiab qis dua AC hlau-kaw switchgear thiab tswj Cov khoom siv" DL404-97 "Technical Conditions for Ordering Indoor AC High Voltage Switchgear"
Lub ntsiab lus qauv
Muaj nuj nqi thiab nta
Lub switchgear yog tsim raws li armored hlau-pob switchgear hauv GB3906-91.Tag nrho yog tsim los ntawm ob ntu: lub txee lub cev thiab qhov nruab nrab-mounted tshem tau ib feem (piv txwv li lub tawb nqa khoom).Lub txee tau muab faib ua plaub qhov sib cais, qib kev tiv thaiv ntawm lub qhov rooj yog IP4X, thiab theem ntawm txhua qhov chaw thiab lub qhov rooj ntawm lub qhov rooj yog IP2X thaum qhib.Nws muaj nyiaj siv ua haujlwm inlet thiab qhov hluav taws xob kab, cable inlet thiab qhov hluav taws xob kab thiab lwm yam kev ua haujlwm, uas tuaj yeem npaj thiab ua ke los ua tiav cov khoom siv hluav taws xob faib hluav taws xob.Lub switchgear tuaj yeem ntsia tau, debugged thiab khaws cia los ntawm pem hauv ntej, yog li nws tuaj yeem rov qab-rau-rov qab, muab ob npaug rau thiab ntsia rau ntawm phab ntsa, uas txhim kho kev nyab xeeb, yooj thiab hneev taw ntawm lub switchgear.
Ib txwm siv tej yam kev mob
◆ Ambient cua kub: siab tshaj plaws kub +40 ℃.Qhov ntsuas kub tsawg kawg -15 ℃.
◆ txheeb ze humidity: nruab nrab cov av noo txhua hnub: ≤95%;ib hnub nruab nrab dej vapor siab tsis tshaj 2.2KPa;Txhua hli nruab nrab cov av noo: ≤90%;Lub hli nruab nrab dej vapor siab tsis tshaj 1.8KPa;
◆ Qhov siab: qis dua 1000m.
◆ Kev siv av qeeg: tsis pub tshaj 8 degrees.
◆ Cov huab cua nyob ib puag ncig yuav tsum tsis txhob pom tseeb los ntawm corrosive lossis combustible gas, dej vapor, thiab lwm yam.
◆ Tsis muaj qhov chaw vibration hnyav.
◆ Yog tias nws siv raws li cov xwm txheej ib txwm teev hauv GB3906, nws yog nyob ntawm tus neeg siv thiab lub tuam txhab sib tham.
